Shark Welding USA PN-26-6M Die Grinder Cut-Off Wheel and Mandrel Kit, 3-Inch x 1/32" x 3/8” Shark Type-1 Double-Reinforced Thin Wheels, 54 Grit (6 Cutting Discs and 1 Mandrel)

Trial use was to cut an automotive wheel bearing race in half and it cut like butter especially when pushed to its rated max speed of 25,000 rpms. Only used one disc, no chips in the disc and it didn’t blow apart. Thumbs up!

Like, did the jobs I wanted to get done

Runs true when used in a drill press. I've used mine for trimming down 223 brass to be sized into 300 AAC Blackout. I made a little jig to hold seven at a time and it cuts very rapidly. I have done over 200 cases so far and it has worn down the disk very little. I don't know how it will cut in steel but for what I have been using it, it does the job nicely.

Very happy with this purchase!

Been using 2 inch wheels. These 3 inch wheel cuts much faster and also cooler because less time to generate more heat. The supplied arbor is a real plus. Did have to dress a tiny bit to run truer. Great wheels.
