Abrasive Grain
typically have higher cut rates than grinding wheels, rubber bonded or cotton
impregnated wheels.
Minimize undercuts – 4" diameter contact wheel less prone to undercuts common
with small diameter (<1") wheels found on most portable belt grinders.
Overall reduced finishing costs – Full utilization of abrasives, quicker initial stock
removal, reduced abrasive change-over time, more localized, smaller repair area.
One tool for complete finishing system – Elimination of multiple tools needed
for cut-down wheels, square pads, and surface conditioning wheels.
Improved consumption of abrasive article – Square pads are ineffective when
corners become worn, access diminishes when surface conditioning wheels wear.
