Gashing with 3M™ Gashing Wheels

3M™ Gashing Wheel, shape 1V1, is used to grind a slot or notch along the cutting face to allow for chip flow. These gashing wheels are available in diamond and CBN mineral.

Primary Relief with 3M™ Primary Relief Wheels

3M™ Primary Relief Wheels with shapes 11V9, 12V9 and 11V5 are used to remove material directly behind the cutting edge, helping enhance chip clearance. This can be done with diamond or CBN mineral.

Cutting with 3M™ Cut-Off Wheel

3M™ Cut-Off Wheel shape 1A1R is used to trim blanks to length. They are typically used on the cutting end of the tool when re-grinding and on the shank end when forming a blank.

End Work with 3M™ Wheels for End Work

3M™ Wheels for End Work in shapes 11A2 and 11V2 are used to grind a small relief angle on the face (tip) of the tool, reducing the contact area between the tool and the workpiece.

Fluting with 3M™ Fluting Wheels

3M™ Fluting Wheels in shape 1A1 and 1V1 will grind either helical or straight grooves into the cutting tool body. This provides a pathway to permit the removal of chips, and to allow coolants to reach the cutting surface.

Secondary Relief with 3M™ Secondary Relief Wheels

3M™ Secondary Relief Wheels are used to grind a slight bevel next to the primary relief. We recommend wheel shape 11V9, 12V9 or 11V5.

OD Grinding

3M superabrasive wheels in shape 1A1 are ideal for grinding round cutting tool blanks to their final diameter. Our diamond and CBN wheels are optimized for OD grinding on carbide and high speed steel.
