NEO TOOLS Diamantová korunová vŕtačka M16, 82 x 10 x 80 mm

Drilling clean, precise holes in hard, brittle materials like porcelain, granite, or marble is a challenge that standard bits simply cannot handle. The NEO TOOLS Diamond Core Drill Bit M16 (82 x 10 x 80 mm) solves this problem with a sintered diamond segment design that cuts through ceramics, tiles, stoneware, natural stone, concrete, and brick without chipping or cracking. Its 82 mm diameter and 80 mm working length make it ideal for plumbing, electrical, and HVAC installations where accuracy and a smooth finish are critical.

Who is it for

This core drill bit is built for professional contractors, tilers, plumbers, and electricians who regularly work with hard surfaces. It is equally valuable for serious DIY enthusiasts tackling bathroom renovations, kitchen backsplashes, or outdoor stonework. If you need to create holes for pipes, cables, or anchor points in tough materials, this bit delivers reliable performance.

Tips

Always use water cooling during operation to prevent overheating and extend the life of the diamond segments. For best results, start the hole at a slight angle and gradually straighten the bit as it penetrates. Ensure the workpiece is securely clamped to avoid movement. When using an angle grinder, verify that the adapter is properly tightened and the tool is set to the correct speed for the material.
