Raizi High Speed Dry Diamond Core Bit for Granite Quartzite (T-segment)

The Raizi High Speed Dry Diamond Core Bit is engineered for fast, clean drilling through granite, quartzite, and engineered stone. Featuring Arix diamond technology and a T-segment cutter head, it runs cooler, cuts faster, and lasts longer than standard sintered or welded core bits.

Key Features

• ✅ T-segment cutter head — safer and sharper than ordinary sintered and welded cutter heads
• ✅ Arix diamond technology — highest quality diamonds placed on inside and outside of the barrel for reduced friction, lower heat, and minimal drag
• ✅ Efficient heat dissipation — strategically placed side holes keep the bit cool for higher RPM performance without compromising lifespan
• ✅ Diamond side protection — enables continuous cutting throughout the drilling process
• ✅ Laser welded construction — durable bond for demanding job site conditions
• ✅ Dry or wet use
• ✅ 40+ holes lifespan — varies by material; built for consistent, reliable performance cut after cut
• ✅ Extendable cutting depth — use extensions and adapters to increase beyond the standard 100mm depth
• ✅ Korean manufactured — premium quality standards
