I bought a cheap chinese cutter from Busy Bee tools for an upcoming project. I have never used one before so I figured I should do a test run and did a little reading about using one. I found a suggested method for an initial cutting sequence, in one of Harold Hall's books. The suggested cut was to take a 1mm depth of cut feeling and listening for any issues, then a second 1 mm cut and after that go to 2 mm. I didn't make it through the first 2" of 1mm deep cut in mild steel before it was obvious this thing was very dull and not going to work.
The saw is an HSS, 2 1/2" x 1/16" x 28 tooth blade. The blade is flat and there doesn't appear to be any rake (set) on the teeth. I ran it at 120 rpm using an arbor I made specifically for it. The blade didn't feel sharp before I started and is definitely dull now. I can see the wear on the sides of the teeth (both sides). It even felt dull on the outside edges of the teeth before starting.
Am I using the wrong tooth count, is this the wrong application for this blade or is there something else I need to be aware of?
