Montolit Mondrillo FPS Diamond Tapered End Mills for Countersinking Holes – Precision Finishing for Smooth, Stress-Relieved Tile Openings

The Montolit Mondrillo FPS Diamond Tapered End Mills for Countersinking Holes are specialized finishing tools engineered to improve the strength and appearance of existing tile penetrations. Designed to chamfer and smooth the edges around drilled or cut holes, these diamond-tapered end mills relieve internal stresses in materials like porcelain, ceramic, and glass — which are prone to cracking or chipping when left rough after core drilling or cutting. 

These tools aren’t meant to drill holes; instead, they work by refining the circumference of a completed opening, reinforcing the edge profile and creating a clean transition that reduces the chance of breakouts under tension or load. Whether you’re working around plumbing fixtures, LED cutouts, or other exposed applications, the Mondrillo FPS gives tile pros a reliable way to achieve cleaner, stronger, more professional hole edges. 

Because they’re suitable for both dry and wet use, you can run these diamond end mills on angle grinders or rotary tools with confidence across a variety of tile materials, keeping your workflow flexible and productive.
