Plunge Cut Blades
on January 31, 2010
The blades are of excellent quality and make precise cuts with ease. I was able to cut through a hidden nail which dinged the blade, but after dressing the blade end on a bench grinder I ended up with a very good coarse scraper (really bites). I noticed the blades have a tendency to loosen with cutting pressure (blade holding area gets rounded & worn from the sonicrafters vibrations). Having 3 worn blades I decided to make a friction washer (60 grit belt sander material). That's sandpaper with a cloth backing, I cut-out circles the same size as the hold-down washer, used a hole punch to make a hole in the center of the sandpaper washer. When installing a used saw blade I put the grit side (homemade washer) against the blade, then the hold-down washer, and finally the set screw. This method worked great to hold the saw blade securely and even after making many plunge cuts the blade never needed to be retightened (this was a used worn blade). This simple "fix" solved the loosening & wearing problem.
