The 3M™ Cut-Off Wheel 654BK is a general purpose cut-off wheel for carbide tool manufacturing. With a highly concentrated diamond abrasive mineral, solid construction and a steel core, it is commonly used for trimming tool blanks on carbides, high speed steels and hard metals. Go-to Wheel for Cutting Tools A "go-to" wheel, the 3M™ Cut-Off Wheel 654BK strikes a balance between form retention and cut rate. It is designed to retain form under use. This cut-off wheel features a steel core. The steel core allows the use of smaller wheel flanges and it improves the lateral stability of the cut-off wheel. The resin bond is designed for use with a water-based coolant. This wheel conforms to the 1A1R shape and is 6 inches in diameter, 0.35 inches thick and the arbor hole is 1-1/4 inches. Recommended Applications This cut-off wheel is an outstanding choice for cutting carbide blanks to length or trimming off the damaged ends of end mills and drill bits prior to re-sharpening. Many other wheel configurations are available.

• Offers balance between form retention and cut rate
• Performs well on carbides, high speed steels and hard metals
• Resin bond construction with 100 mesh diamond mineral
• Typically used on the cutting end of the tool when re-grinding and the shank end when forming a blank
• Coolant: water oil emulsion
