6mm Diamond Hole Saw Drill Bits, 15 Pieces

These diamond hole saw drill bits are designed for precise drilling through hard materials. Each set contains 15 pieces with a 6mm (1/4″) hole diameter and 52mm total length, delivering clean, accurate cuts every time.

The bits are manufactured from high-quality iron alloy with a corrosion-resistant surface coating for long-lasting durability. The efficient cutting design features large clearance holes that maximise water flow for cooling and chip removal, enabling smoother and faster drilling without compromising quality.

Suitable for glass, ceramics, porcelain tiles, marble, granite, quartz, limestone, and fibreglass. Ideal for both DIY and professional applications, whether tiling, renovations, or specialist projects requiring precision drilling.

For best results, start drilling at a 45-degree angle and gradually align to 90 degrees as the hole forms. Always use water for cooling to extend bit life and improve cut quality. The robust construction handles demanding projects while maintaining accuracy across multiple uses.

Start with water cooling and begin your next project with confidence.
