GRAIN

            • A – Aluminum Oxide: for general purpose use on all metals except titanium

            • C – Silicon Carbide: for use on non-metallics and titanium

 GRIT

            • 24 – Coarse: for fast cutting and maximum wheel life

            • 30 – Medium/Coarse: for fast cutting and long wheel life

            • 36 – Medium/Coarse: excellent for general purpose cutting

            • 46 – Fine/Medium: for a smoother finish and reduced burr

            • 60 – Fine: for a burr-free cut

            • 80 – Fine: for a burr-free cut

GRADE

            • T-V – Hard: for maximum wheel life

            • R/S – Medium/Hard: for improved stock removal

            • E-N – Soft: for maximum cut rate

 

Soft vs. Hard Wheels

SOFT

• Shorter wheel life

• High stock removal

• Faster cut

• Large contact areas

• Less bond holding the grain together

HARD

• Longer wheel life

• Lower stock removal

• Slower cut

• Finer finishes

• Small contact areas

• More bond holding the grain together
