Dremel 506CU 7/8-Inch Premium Metal Cutting Rotary Wheel

The 506CU cutting wheel features a super abrasive grit called cubic boron nitride or CBN. CBN used on a cut-off wheel allows the wheel to remain sharp longer, stay cool, and it won’t shrink or break. When mounted on a Dremel Rotary tool, the Premium Metal Cutting wheels have 20X longer metal cutting life than most Dremel cut-off wheels. There is also no wheel breakage or shrinkage to create the most durable Dremel rotary metal cutting wheels. This saves time, storage space and cuts costs. For use with the 402 Mandrel with screw.Long life: At least 20x longer metal cutting life than standard Dremel rotary fiberglass reinforced cut-off wheels
