Flexovit® 4-1/2" X .045" X 7/8" RAZORBLADE 27® 60 Grit Aluminum Oxide Grain Reinforced Type 27 Depressed Center Cut-Off Wheel (A0481 Pack of 25)

Cost a little more,but work a lot faster. I cut .100" SS sheet, these cut quick, are easy to cut a straight line with, last a good while.

With the reinforcement in the blades they don’t blow apart like several other brands that I have tried. The offset mounting style make it much easier to cut close to other close pieces with a straight cut. If you keep the cuts flat and don’t wear down the top or bottom sides of the wheels they last even better.
