Features Benefits
• Aluminum oxide abrasive • Fast cut rate and long life
• Resin bond • Free cutting action
• Burn-free cutting
• High strength, reinforced • Resists breakage and
construction provides straight cuts
• BFTK - side reinforced, • Maximum cut rate
rough sides
• Decimal thickness • Very narrow cuts; minimum kerf loss
• BFW - side reinforced, • Versatile; durable free cutting
rough sides
Used primarily for cutting off high speed steel drill bits
and end mills, as well as slotting dies.
Features Benefits
• Aluminum oxide abrasive • Fast cut rate and long life
• Resin bond • Free cutting action
• Burn-free cutting
• Long life
For use on machines where the work is rigidly clamped
and the wheel operates on a controlled cutting plane
with no twisting or lateral stresses. Ideal for slotting
dies or cutting off high-speed steel drills and end mills.

TechTip
• Reinforced cut-off wheels are designed to resist breakage caused by severe
cross-bending and are required on any operation where the work is not securely
clamped.
• Non-reinforced cut-off wheels are designed for use on “fixed-base” types of
machines where the work is securely clamped, guarded, and where the wheel
operates on a controlled cutting plane.
It is the user’s responsibility to refer to and comply with ANSI B7.1
