Quality Hole Saws

by
I recently ordered 3 of these hole saws: 1-3/8", 2-1/2", & 3-1/2". I used them to drill some very dense, very brittle porcelain. They worked beautifully on my Makita's slowest speed. I bought the adapter to use the hole saws with a 1/2" drill, but have yet to use it.
If you need quality hole saws at a reasonable price look no further.
