Description
KEYSTONE Green MOUNTED Silicon Carbide STONES,
HP MOUNTED Silicon Carbide Stone · Green Large Taper (I-6) [1631210] 12pk
Overview
KEYSTONE Green MOUNTED Silicon-Carbide STONES are the lab bench abrasive for grinding and contouring porcelain restorations, fired ceramics, and dental composite. Green silicon-carbide STONES cut hard, brittle materials at a controlled rate without glazing the surface — ideal for shaping porcelain margins, adjusting bake-on opaque, and trimming composite test pieces on the lab bench.
Color-coding is critical to using MOUNTED STONES correctly: each color is formulated for specific materials. Green is for porcelain and composite. (Pink is for precious-metal ceramics; blue is for chrome-cobalt finishing; white is for non-precious ceramics; red is for general purpose lab work.) Using the wrong color costs time and can damage the work — always read the color first.
- Green silicon-carbide bond. Engineered specifically for porcelain and composite — cuts hard ceramics at a controlled rate without glazing.
- 3/32" HP shank. MOUNTED points are pre-MOUNTED to the universal lab handpiece shank — no separate mandrel needed.
- Multiple head shapes. Taper, inverted cone, round, barrel, and knife-edge geometries for every porcelain contouring task.
- Predictable wear rate. STONES wear at a consistent rate, giving technicians control over removal depth without overshoot.
- Standard 12-pack or 72-pack box. Sized for high-volume labs.
