Product information

Description

【PRECISE POSITIONING】: Compared to conventional glass hole saws, our hole saws have positioning aids. The pilot drill in the center helps you position accurately, ensuring the drill bit doesn't slip or jam, and helps you drill precise holes.

【CUTTING EFFECT】: The diamond surface coating uses sintering treatment methods. The cutting edge contains diamond particles from the inside out to guarantee it remains sharp. Low cutting resistance and stable drilling produce smooth, high-precision cuts without chipped edges for optimal cutting results.

【HIGH-QUALITY MATERIAL】The diamond hole saws are made of industrial-grade, high-strength carbon steel, and the surface is nickel-plated, which is effective against corrosion and rust.

The drill bit's diamond surface coating is thick and uniform, improving wear resistance and extending its lifespan. 【CHIP REMOVAL DESIGN】: The cutting head of our diamond drill bit features a notched design with side through holes. This design prevents the ingress of cooling water and ensures that chips and other particles are expelled through the through holes during operation, making drilling more convenient and efficient. 【WIDE APPLICATION】 The diamond drill bit is suitable for cordless drills, lithium-ion drills, and bench drills. It is widely used for cutting precise holes in glass, ceramics, porcelain, tile, limestone, slate, marble, pumice, and fiberglass.
