GRAPHITE Diamond Drill Bit for Porcelain Stoneware 83 mm, M14 Thread

Cutting clean holes in hard porcelain stoneware demands a tool engineered for the job, and this 83 mm diamond drill bit from GRAPHITE delivers exactly that. Built for use with angle grinders, it features an M14 thread shank and a continuous diamond rim that slices through tough ceramic materials without chipping or cracking.

Highlights

• 83 mm diameter for large openings – ideal for sockets, pipes, and plumbing
• Continuous diamond rim ensures clean, chip-free cuts
• M14 thread shank fits standard angle grinders
• Suitable for dry drilling; wet drilling extends bit life
• High-grade steel body with industrial diamond coating for durability

In daily use

Mount the bit onto your angle grinder and mark the drilling spot. For best results, start at a slight angle to create a groove, then straighten to full depth. While the bit is designed for dry use, adding water cooling will significantly increase its lifespan, especially when drilling granite or marble. The 35 mm drilling depth covers most tile and stone thicknesses encountered in renovation and installation work.
