Diamond hand pads fill the gap between CNC finishing and installation touch-up — essential for corners, curves, and field repairs.
Even the best CNC workflow leaves corners, lamination seams, and field-cut edges that need manual finishing. Diamond hand pads — flexible pads with resin-bonded diamond grit on one face — give fabricators and installers a portable tool for blending profiles and removing micro-chips without hauling a polisher to every jobsite.
Where Hand Pads Outperform Machines
Inside radii, sink clip cutouts, and back-splash inside corners, rigid polishing wheels cannot maintain even contact. Hand pads conform to the surface, distributing pressure evenly and preventing flat spots that telegraph through the finished polish.
- Inside corners: Blend CNC profile transitions on bullnose and eased edges.
- Lamination seams: Level epoxy lines on mitered waterfall joints before final polish.
- Field repairs: Remove installation chips on granite and quartz without dismounting the countertop.
Grit Sequence and Usage
Follow the same grit progression as machine polishing — typically 50, 100, 200, 400, 800, 1500, and 3000 for a full granite polish. Skipping grits leaves scratches that appear only under raking light. Protec Tools hand pads are color-coded by grit to reduce operator error in busy shops.
Wet vs Dry and Pad Life
- Use water on granite and quartz to extend pad life and control dust.
- Dry use is acceptable for brief touch-up on pre-sealed surfaces.
- Replace pads when grit feels smooth and cutting action stops — continuing wastes labor.
