⚡ At a Glance
- • Cutting Quality: Diamond grit and carbide tip deliver clean holes with minimal chipping
- • Best for: DIYers and tradespeople working on tiles, stone and masonry
- • Not ideal for: Hammer-mode drilling or cutting through reinforced steel
Diamond bits are intended for wet or dry tile and stone drilling while the carbide-tipped eccentric bit handles pre-drilling and positioning. A 6.35mm hex shank enables quick, slip-resistant bit changes.
Accurate Positioning and Faster Anchors - with a carbide-tipped eccentric drill bit
Carbide drill bit measures 90mm in total length with a 54mm working depth, designed for pre-drilling and rapid penetration in softer masonry and brick. Dry drilling is suitable for materials such as wood, plastic, foam, red bricks, cement and concrete, but rebar must be avoided.
Precise pilot holes make fixing anchors and fixtures easier and reduce the chance of slippage when following up with larger bits. Faster pre-drilling speeds up routine installation tasks on-site.
Clean Holes in Tile and Stone - thanks to diamond-tipped bits with 50/60 grit
Diamond drill bits have a total length of 65mm, with an 8mm diamond height and 50/60 grit specification, suitable for dry or wet drilling on tiles, ceramics, granite and marble. Wet drilling can extend bit life and reduce dust when working on harder surfaces.
Holes for fittings and pipework appear with minimal chipping and smoother edges, so patching and finishing time is reduced. Wet or dry operation gives flexibility depending on site setup.
Quick Fit and Secure Grip - with a 6.35mm hex shank for common drills
All five bits have a quick-fit hex shank (6.35mm / 1/4" flats) to prevent slipping in chucks and to speed up bit changes. Suitable for ordinary hand drills, table drills and rechargeable lithium-ion drills with power higher than 24V, but must not be used in impact or hammer mode.
Rapid swapping between the carbide pilot and diamond cutters keeps workflow moving, and the slip-resistant shank reduces round-hole wobble during drilling. Compatible with widely used drill types on most sites.

❓ Frequently Asked Questions
Q: Are these bits suitable for cordless drills?
A: Yes. Compatible with ordinary hand drills, table drills and rechargeable lithium-ion drills with power higher than 24V, provided impact or hammer mode is not used.
Q: Can the diamond bits drill porcelain, marble and glass?
A: Diamond bits are suitable for tiles, ceramics, granite and marble and can be used wet or dry; for vitrified/full-ceramic tiles, marble and glass, use coolant as recommended.
Q: Can the carbide tip be used on reinforced concrete or in hammer mode?
A: Avoid drilling through rebar with the carbide tip and do not use impact or hammer mode, as that can damage the bits and the workpiece.
🏆 Our Verdict
Ideal for DIYers and tradespeople who regularly drill tiles, stone and standard masonry, offering a mix of diamond cutters and a carbide pilot for versatile jobs. The combination of 50/60 grit diamond cutters, an 8mm diamond height and a 54mm-working-depth carbide pilot gives precise, low-chipping holes. While representing an investment above basic bits, durability and included spares deliver long-term value for frequent use.
