DEDRA CORONA DE DIAMANTE SOLDADA AL VACÍO M14 50MM PARA CORTE EN SECO DE AZULEJOS, PORCELANA, GRANITO

Where standard diamond bits glaze over and burn out on dense porcelain or natural stone, the DEDRA DED1592S50 vacuum brazed core drill bit keeps cutting cleanly without water. Its 50 mm diameter and M14 thread mount directly onto any angle grinder, turning a common handheld tool into a precise hole-cutting system for tiles, stoneware, granite, marble, and even glass. The continuous diamond rim is bonded to a high-grade steel core under vacuum, exposing sharp industrial diamonds across the full cutting edge for fast, chip-free results in dry conditions.

Highlights

• Vacuum brazed diamond technology for superior grit retention and long life
• 50 mm cutting diameter with continuous rim for clean, chip-free holes
• M14 thread fits standard angle grinders — no special arbor needed
• Dry drilling: no external water cooling required, ideal for finished spaces
• Cuts ceramic tiles, porcelain, stoneware, granite, marble, natural stone, and glass
• High-grade steel core resists flexing and heat buildup
• Industrial diamond grade for professional durability and repeat use

In daily use

This bit is built for electrical sockets, pipe penetrations, and fixture holes in hard, brittle materials. The vacuum brazing process holds each diamond firmly in place, preventing the premature loss of abrasive that plagues electroplated bits. Because it runs dry, you can work in finished bathrooms, kitchens, and facades without messy slurry or cleanup. The continuous rim distributes cutting pressure evenly, reducing edge chipping on glazed surfaces and leaving a hole ready for escutcheons or flanges. For best results, use a medium speed on your angle grinder and let the bit do the work — no hammer action, no water feed.
