Application Color Coding
The horizontal and vertical colored
bars indicate the material(s) that this
product can grind or cut:
RED – steel/metal
BLUE – stainless steel
GREEN – masonry
GREY – aluminum
YELLOW – foundry-specific materials
Diamond Marking System
A quick reference to performance
– higher number of diamonds
represents better performance grains
with faster cut rate and longer life than
those with lower diamond values.
Application Icons
Show material to be cut or
ground. Also can indicate if
grinding or cutting wheel is
iron-, sulphur-, or chlorine-

Troubleshooting Guide
PROBLEM POSSIBLE CAUSES SUGGESTED CORRECTION
Poor cutting rate Insufficient power used Increase feed or pressure to full power
Wheel too hard Use softer grade, Free Cut or thinner wheel
Contact area too large Reduce contact area
Wheel too coarse Use finer grit or Free Cut wheel
Wheel side out of truth Check spindle runout
Non-square cuts Work not clamped properly Check clamp and clean to remove swarf
Misaligned spindle bearings Check for bearing truth and alignment
Poor coolant distribution Ensure equal volume of coolant to each wheel side
Wheel is too hard Use softer acting wheel: softer grade, or finer grit, or Free Cut
Workpiece burn Insufficient feed rate Work machine to maximum power available
Poor coolant flow Increase volume and direct at cutting point
Wheel is too coarse Use finer grit or Free Cut wheel or more machine power
Wheel is too hard Use softer grade, thinner, or Free Cut wheel
Wheel is running out Check spindle and flanges
Wheel speed is too slow Ensure tight flanges and observe maximum speed on wheel
Poor finish Too much burr Use finer grit, or softer grade, or Free Cut wheel
Wheel too coarse Use finer grit or Free Cut wheel
