This has not been a good week for me and my motiser. I needed a 5/16” chisel/bit for the project I am working on. I did the first couple of mortises with my 1/4” bit, but since the mortises are 3 1/2” long, I was heating up the bit after having to basically cut each mortise twice to get the full width. I decided I should get a real 5/16” bit.
My first mistake was the CMT bit I ordered on Amazon—too much in a hurry and didn’t realize it was for a drill press.
So this morning I drove to Woodcraft first thing and picked up a 5/16” bit from them. It says it fits all the standard Asian mortisers. But the Woodcraft bit is only 2 12” long below the color compared to the 3 1/2” of all my other bits. It worked, but I had to hand chisel the bottoms out because I need space for 1” tenons on this plan. I have an x-y vise and I can only raise the work piece so high and still hold it securely.
Seems like for most chisel/bits on web sites, they only give the shank and set sizes, but not the length below the collar.
Now I’d like to find some 3 1/2” length bits. Any advice?
