Upgrade your Scroll Saw with Pegas Blade Chuck Heads - 40% lighter, Less Vibration.

See list below for compatibility - This version also works with DeWalt and Delta models listed below.

Upper and Lower Scroll Saw Blade Clamp Replacement Set.  These new “Blade Chuck Heads” (also known as Scroll Saw Blade Clamps) were developed in Switzerland by Pégas in association with the HEIG engineering school in Yverdon. 
The studies and the tests demonstrated that the weight of these heads is in direct relation with the service life and the vibrations of the machine.

1) These new heads, manufactured with aeronautical aluminum for resilience and optimal weight, are 40 % lighter than you original Heads. 

2) Vibration will be greatly reduced

3) Changing Blades is easier and faster

4) Better protection of the mechanical parts of the scroll saw.

As you can see, they are clearly more compact than original heads and even easier of use. The assembly of these new Heads is very simple and takes only a few minutes.

Note - The Set Screws and Thumb Screws are wear parts on any blade clamps, and should be replaced every few months or couple of years depending on how much you use your scroll saw - Click here to see our selection of renewal kits.

Top and Bottom Clamp replacement (No tension lever as there is one at the front of these saws) For DeWalt 788 and Delta 690 Review by Steve Good.



Bottom Blade Clamp replacement. (Want to change both clamps? Order the Original. JET JWSS-22 Scroll Saw.  See Steve's comments in the post on the Original. Review by Steve Good. 

All parts are included to make this quick and simple scroll saw blade clamp replacement. Steve Good's review also shows how to remove your existing blade clamps and install the new one.



Aeronautical Grade Aluminum clamp.

There is a swivel on the end of the thumb screw that contacts with the blade. Instead of the blade spinning when you tighten it down, the swivel stays in place on the blade allowing the thumb screw to rotate without turning the blade.

I forgot the dates already but my order arrived four days later. This for me is very fast, an amazing service considering that I am from the Philippines and right at the middle of Quarantine lockdown where I live! Super! Thank you. I will surely place an order again.

Excellent quality, fast service 11/27/2021
By Robert Fredrick
I have a Jet 22" scroll saw, and was having trouble with blades slipping from the upper blade holder. The Jet factory was not able to diagnose the problem. I replaced the spring (and I think another part, but I can't remember which one), but that did not solve the problem. It was after that I decided to purchase the Pegas scroll saw chuck head kit.

Everything comes in a plastic case that holds the parts in foam. I am a woodworker but not much of a mechanic, but I found the installation intuitive. Actually, the most difficult part was removing the old lower blade holder because it was somewhat stuck and hard to get an allen wrench into that tight space. I made more room by tilting the saw, and everything went smoothly after that.

The Pegas heads work great. I am used to threading the blade from the bottom up, so I still do that. It's easy to tighten blades in both the lower and upper holders, then flip the lever up to tighten the blade. The saw is working great since the upgrade.

Amazing 11/26/2019
By Steven Hauser
I teach technology education and have a Hegner, an old 440 delta scroll saw, excalibur and a pegas saw(recently purchased) as part of my tech shop. The excalibur scroll saw was lying around like a shiny paper weight that never really held blades until I installed the Pegas chuck. Thanks to the Pegas chuck the Excalibur saw has been rejuvenated to a fine working, low vibration saw. Students use this saw daily in an inconsistent manner, pushing too hard sometimes with only one blade slipping off over a month. The new chuck makes the excalibur more enjoyable to use then the expensive Hegner that is sitting next to it. The Hegner is a great sturdy saw however the table is smaller and runs a little rougher. The trick with the Pegas chuck is only make it hand tight and it will hold the blade fine. I believe once you start wrenching the clamp down too tight that is when it will ruin. Finally the red anodized color makes this chuck really cool. BTW the old Delta is one of the most precis

Great Product 07/27/2019
By Jeff Vortisch
I purchased a new Seyco ST-21 in January of this year. I love the saw but very disappointed in the upper and lower blade holders. I never could figure out just how to easily to put either the top or bottom blades back into the holders. Sometimes it took close to a half a minute for get the top blade back into the saw. I heard about these replacements and based on the cost I hesitated in getting them. Finally two weeks ago I ordered them, They arrived on Tuesday and I installed them on Wednesday. I absolutely have to say this was the best money I have ever spent. This made my saw exactly what I wanted. The blade changes or now so simple and easy. I loved my saw before but now I would not trade it for any thing. And as a side note, I was considering the Pegas with the Seyco when I ordered my saw. I choose the Seyco only because of the table size. Thanks again for offering this great product.

Pegas Heads 03/25/2018
By Rodney Trezise
I replaced my original Excalibur blade holding heads with the Pegas ones. Very quick and easy to install.
The Pegas heads are less cumbersome and a bit easier to use than the original items.
The Pegas heads also seem to tighten the blade to the correct tension when flipping the tension lever. My original excalibur heads didn't seem to tension enough. I was always tightening the tension knob at the back of the machine by about 1/8th to a 1/4 of a turn to get the blade tight enough. I don't have to do this with the Pegas heads, just flip the lever and cut.
This makes the whole process a lot quicker, particularly with internal cuts where the blade is constantly being installed etc.
Good quality item and well made.

An improvement for sure 08/10/2021
By Robert A Kruszewski
I replaced these on my Excalaiber Scrollsaw. One of the top screws had to be rubbed with wax to get it to screw in , ot really was a tight fit. The top handle, tensioner, while holding the blade in tension seems to have 2 positions. While it stays in the first back position, it does not in the all the way back & down.( not sure if it is supposed to?). It is so easy and light to the touch that you would think it wound not hold, but it does! However it greatly improved the performance of my Excalaiber. I do not struggle changing blades or scroll sawing.Those little pivots on the blade holders are a great asset in holding the scroll saw blades too! I could use them my Hawk G4. Thank You, Robert.

It was all good!! 10/08/2020
By Rod Martinez
I purchased the Pegas blade chucks and they are great the packaging and delivery was outstanding!! I have an old EX30 and didn't use it for over a year cause the blade kept slipping out. I started scrolling in 1980 with an rbi hawk got purty good at it and started selling them at fairs and trade shows. after wearing out 3 rbi hawks I tried a Hegner in 1990 and started selling those I was given the EX30 and didn't like it. Now that I got the blade chucks from ya'll it much better I use it for the long things and my Hegners for most everything else my chair has wheels so I have them down low! Cheers to a Job well done!!

Love these chuck heads 08/31/2023
By Robert Fredrick
I have a Jet scroll saw, and I replaced the original heads with the Pegas. They come packaged in a plastic case with foam protection. I'm not a great mechanic, but I found installing these new chuck heads to be an intuitive process. The most difficult part was removing the screws from the old heads.
The Pegas heads hold the blade securely in both the upper heads, and changing the blade is quick, requiring no tools.
If you are thinking of upgrading your scroll saw with the Pegas heads, stop thinking and order!
Bear Woods fills orders quickly and they have a great customer service department.

Product and Service Satisfaction. 08/16/2018
By David Gandy
I ordered the new Pegas Blade Chuck on Aug. 10th, and received it and some blades on Aug. 15th.
The product was well packed, and easy to remove.
I did have an issue with removing one of the bearings

that was in the saw, but once I got it out, everything went great.
The hardest part of using the chuck is learning just how easy it is to operate.. No slip, no loss of tension.
When I inured about the product, the people at Bear Woods were very helpful.
Very happy with mdse. and service I received from Bear. I highly recommend them.

Pegas Heads 08/07/2018
By Charles Green
They do improve my saw!!! I was able to cut out one compound cut rose leaf, both sides with one blade. Before I had to use two blades. I did not have any release problems from the tension lever. They took off about 5-8 minutes in cut time for each leaf. There is no side give when cutting the thicker side of the pattern which creates a square cut resulting in the finished piece just falling apart. There was also no problem with heat burning the material. I am very satisfied with the performance of the saw since attaching the heads. I will recommend them to my friends. Thank you.

High quality 08/22/2019
By Robert Stavis
Outstanding product. Makes blade changing easier. Blade is very secure, retaining proper tension. I have no reluctance about releasing the blade to make an interior cut because I know how easy it is to re-secure it. Installation was easy, although some instructions would have been nice. It was harder to remove my old chuck heads than to install the new ones. The new heads arrived very timely and very well packaged. A high quality product that has helped me with scroll sawing. I will certainly do additional business with Bear Woods. Excellent product and excellent company.

Fantistic 12/10/2018
By Harry Webb
I ordered these chuck heads by Pegas and hoped that they would make a difference. What I found is that they make a huge difference in so many ways. The saw runs quieter, there is less vibration, and finally, I can now see where the blade goes in the chuck. I can't understand why the scroll saw manufacturers don't use a similar approach. They were quite easy to install and I noticed such a difference right away. Well worth the price. I saw one review that said there was not much difference...I seriously object to this opinion.

Excalibur Heads 09/26/2018
By James Reitz
Fixed problems scroll saw had since purchase. My saw was made just before Excalibur disappeared from market place. The pegas heads fixed most of the quaility problems from manufacturer. Wish I'd found them 2+ years ago. Thats Steve Good for reviewing this product. The Pegas blades are another joy. Been using FD for many years. For some reason the last couple orders of FD blades have suffered from quality problems. Again, the Pegas Blades are really great!

Excellent quality and easy to install 03/06/2019
By Anna R.
I have an Excelsior 16" scroll saw and do a lot of fretwork. My original chuck head had worn out and I was told that in order to replace some or all of the parts, I'd have to order each piece separately! When I saw the Peas complete set, I ordered it for its simplicity and Pegas' reputation for quality. It really was easy to install and it's easy to use - no more fiddling to get the blade to hold and tension properly. The order was received promptly too.

Pegas Blade Chuck Heads 03/04/2019
By Steve
Installed easily and worked great the first time I used them. Noticed an immediate improvement over the Excalibur clamps. Worth the price to not have to worry about blade slippage.
Need to provide instructions on how to install/adjust the screw/thumb screw to get the correct setup to clamp the blade. I have used and adjusted my Excalibut saw for years and knew the procedure. It may be a little different for the Pegas clamps.

It works 05/25/2018
By Roberta Moreton
When I bought my EX 21, I had problems with the blade slipping, tension relaxing, I replaced the top white tension thing, no help. I sanded the ends of my blades, no help. I hated my Saw.
I should have kept my old one.
Then I bought the Pegas Chuck Heads. Now my EX runs so much better! It is like finally getting the saw I was expecting when I bought my EX!
All problems solved! Easy to use, works every time! Thank You!

Scroll Saw Chuck Heads by Pegas 08/01/2018
By Bryce Landenberger
I'm very happy with these heads. My old heads were getting somewhat worn and had a tendency to release mid-cut. These were easy to install and seem to work very well. While it is somewhat subjective they appear to reduce the vibration, but what is clear is that the flip lever appears to engage more easily and does not give any indication that they will slip like my old heads. In my case it was money well spent.

Purchased these recently and they arrived with a bolt missing. After emailing, the bolt was couriered to me promptly - great service! These clamps exceeded my expectation - my saw is now fun to use. They make blade changing easy and the EX21 is now rapidly becoming my favourite to use after gathering dust for a year or more. I will recommend these clamps and Bear Wood to anyone interested

Do you have replacement set screws and tips. Same problem as with original parts on Excalibur saw. The clamp (top does seem to work better, but bottom clamp worked better for a while, but now blades are slipping. I am a top feeder. Approximately 1000 cuts on clamp. Thought servo repair screw and tip would work, but it is shorter. Are replacement sets available?

The Pegasus blade clamps far exceeded my expectations. They highly improved the slight vibration of my saw that I was not aware of until they were installed and in use. I highly recommended them for any saw they might fit. I do wish they had some instructions to work with. Even without the instructions the clamps were not difficult to install.

Pegas Chucks. 04/19/2019
By Bob Tucker
The Pegas Chuck Heads are doing what I was told they would do. I saw about four hours a day and I wanted chucks that would hold up. Time well tell the story. Shipping was to long. It took 9 days. Most other things I order I can get in about a week. Question: Do you sell just the insert to these chucks as well?

Pegas blade chuck 01/14/2019
By freeman pascal
Installed on my saw was very quick and easy. I would give it 6 stars if I could. I thought I had a new saw. What I like most is the ease of changing blades. I can see the top of the blade to clamp it. To say that it is the best thing since sliced bread and bottled beer is an understatement. Would I recommend it to other scrollers? yes

Blade chuck 05/18/2024
By Terry Muller
Blade chuck is a pegas product and is of the highest quality. Bear Wood customer service is a complete joke. After multiple tries, both phone and email they DO NOT RESPOND. A snail mail letter to the owner received no response. Buy your pegas blade clamps from Pegas direct and avoid Bear Wood completely.

I had seen many people talking about this head and wondered if it was as good as they said. It is! Easy to install and easy to change blades, and reduced some of the vibration. If you are looking to replace the head on your scroll saw, I would recommend the Pegas. It is money well spent.

Nice update 04/10/2018
By Sherman O Loges
Got these clamps installed, then took them for a test drive was amazed at how smooth the cut was. Part of the improvement was due to the fact that the original lower blade holder was damaged from the use of pliers to get the blade to stay put, resist.
