4" 4.5" 5" Premium Cupwheels

Engineered for precision grinding in confined spaces, these 4″, 4.5″, and 5″ cupwheels are purpose-built for edging, step treads, vertical surfaces, and overhead work where larger tools aren’t practical. Built with pro-grade diamond segments in aggressive and fine profiles, these wheels offer fast, clean prep with minimal chatter or overcut.

Select from super coarse 16/20 grit, 30/40 coarse grit, or specialty PCD designs to match your removal rate, surface hardness, and prep strategy. Teardrop and small-tooth segment layouts reduce scratch patterns while delivering consistent material removal under demanding field conditions.

All wheels are compatible with most 4.5″–6″ angle grinders and mount directly without adapters. Designed to pair with dust shrouds like the Dust Avenger for compliant dry grinding on slab edges or vertical walls.

• Optimized for edge work, risers, wall bases, and detail prep
• Available in 16/20, 20/25, 30/40 60/80 100/120 grits, and PCD for coating removal
• Fits standard small angle grinders with 5/8″-11 arbor with or withour dust shrouds

Choose the right cup to match your method—maximize speed, edge quality, and surface consistency with pro-grade tooling.
