Sintered Diamond Drill Bits for Stone & Granite

Sintered Diamond Drill Bits for Stone – Heavy Duty Core Bits | XTREME

The XTREME Sintered Drilling Core Bit Type A is a high-performance tool designed for professional masonry and stone fabrication. These diamond drill bits for stone are engineered with advanced sintering technology, which bonds industrial diamonds deep within the metal matrix.

This ensures that the drill bit maintains its sharpness and structural integrity even when working on the toughest granite surfaces. Whether you are installing kitchen countertops or performing architectural stone carving, this tool provides the reliability and speed required for heavy-duty industrial applications.

Deep Insights: Why Choose Sintered Over Vacuum Brazed?

When searching for the right drill bit for stone, it is important to understand the durability of the tool. Our Type A sintered bits feature a 10mm segment height. Unlike thin-coated bits, the diamonds are embedded throughout the entire segment. As the metal bond wears away during the drilling process, new sharp diamonds are constantly exposed.

This “self-sharpening” effect ensures a consistent drilling speed and a much longer tool life, making it a cost-effective choice for high-volume stone workshops.

Key Features

Long-Lasting Durability: The sintered metal bond provides a significantly longer lifespan than standard vacuum brazed or electroplated bits.

Fast and Smooth Cutting: The segment design reduces friction and allows for efficient debris removal, preventing the stone drill from overheating.

Precision Engineering: Each bit is balanced to minimize vibration, ensuring that every hole is perfectly circular and free from edge chipping.

Versatile Connections: Supports multiple thread types including M12, M14, 5/8″-11, and 1/2″ Gas to fit various international machine standards.

Wide Size Range: Available in diameters from 6mm up to 100mm to cover every possible project requirement.

Technical Specifications

A high-quality stone drill bit is essential for creating clean and precise holes without cracking the surrounding material. This series is optimized for:

Granite Drilling: Specifically designed to handle the high density of granite slabs.

Stone Installation: Perfect for creating faucet holes in countertops or passage holes for plumbing and electrical lines.

Dry Use Performance: Engineered for dry use on angle grinders, providing convenience for on-site construction where water access may be limited.

Machine Integration: Compatible with standard angle grinders and professional drilling machines using M14, 5/8″-11, or 1/2″ Gas connections.
