I need a blade clamp for a model 105112 Mastercraft jig saw. Is there a substitute or universal clamp that fits?

Sorry we do not sell parts here.

This tool has no mechanism for the fixating ot the saw but only a short ***** part 53 its a fault in the manual , it simply replace the saw with a screwdriver. or simply the clamp ***** to release turn it loose and from the top you can replace the clamp *****

Try going to a store that sells scroll saws and look at the new models to see how they hold the blade. Take your Dremel with you. Maybe you can find one that is similar enough that could work if you can get the part. Then go to the tool company's web site and search for the manual for the comparable tool you found - they all have on-line manuals nowadays. You should be able to order the part you need. Good luck!

To remove a blade on this saw, lift the knob on the top of the saw and rotate the knob counterclockwise. This will open the blade clamp. The blade should slide out. To install a blade, slide a blade in, being sure the back of the blade fit against the support roller. Clamp the blade in place by turning the knob on top of the saw clockwise until you hear a clicking sound, then push the knob down.

Hope this helps.

do you have the screwdriver that came with the saw? if not you need a longer straight slot screw driver and it must be ground down to fit into the blade clamp tightener. it is a narrower than usual screw driver. I lost mine and had to custom make one. good luck.

There is no model 7580 Jigsaw. The only model close to that I can see would be the 7588 Type 4. Unfortunately that part is unavailable for this model. You may want to contact your local Dewalt service center and see if there is a substitute for that part.

If you just loosen the screw enough,It will fall out.

take your saw to any hardware store and they will sell you a blade that fits your saw and show u how to change the blade. not all blades fit all jig saws.

Here is a link to the instruction manual, and just under the place where it says Save These Instructions it tells you how to change the blade.

Fitting the saw blade (figure A)
- Hold the saw blade (9) as shown, with teeth facing forward.
- Push the lever (3) downwards.
- Insert the shank of the saw blade into the blade holder (10) as far as it will go.
- Release the lever.

There is a little lever where the base of the blade fits into the holder that you depress to release the blade...You can see a picture of it in the manual.

I hope this answers your question...if so, please take a aec to rate this post...thanks.
