Screeching Mortiser

The bit shouldn’t be tight in the chisel. When setting it up, push the bit up until it comes in contact with the chisel and then let it back out about 1/16”. This might solve your problem.

General chisels seem pretty nice. I’ve hardly used mine, but they seem to do the trick.

I have been using Fisch bits. Hold an edge well good chip clearing.

Thanks, I did try it 2-3 times to see if it would resolve it but it didn’t do the trick.

John and Peter thanks for your advice on bit brands.

I have the same powermatic mortiser for 2+ years now and I like it very much. Here is a link that will give you some good info for fine tuning and setting it up.

Don’t trust that the chisels that you bought are sharp, many a times when the mortiser is strugling is due to not so sharp chisels.
Get yourself the sharpening tool for hollow chisels it is not that expensive.
Also if the bit is too tight inside the hollow chisel maybe they gave you the wrong bit? If the bit is the correct size then I would return the hollow chisel and get a replacement. I doubt Woodcraft will not make it right for you.
Have fun with your new toy….
