🔪 High-Speed Stainless Steel Cutting Tools by Rocaris - Hole Saw Review

I received this product the day after I placed my order and started work. I drilled holes in thick 10-12 steel studs. After 14 holes the bit feels as sharp as I got it. I usually drill about halfway through (at a slower speed), then apply lube to the cut and finish the hole. The first pilot bit broke on the second hole, but I think it's because I didn't tighten it properly. I simply replaced it with one of the similarly sized bits, tightened, and continued drilling. This product definitely met…

I used several of these sizes to cut holes in the 1/16" tin case for the knobs. Buying a set was cheaper than I needed separate saws, so I took a chance. It cut through the metal fairly quickly with no problems. He left a clean hole that was easy to smooth out. I don't know about long-term use. I also appreciated the separately labeled drawers for each bit. This made it easy to find the sizes I needed and organize them with my tools. Overall happy with the purchase.

God these puppies are amazing. I used them in an M12 Milwaukee drill. For those of you who don't know, the m12 doesn't have enough speed or torque, no matter what Milwaukee claims, but they're amazing and they've gotten better. I bought this set for the 24mm crown only, but figured I'd find a use for the others as well. I drilled about a dozen holes with each crown to test them and for the most part they held up great. And some of them are close enough to be used for fittings. Pros: 1) damn…
