Frequently asked questions

Does this bit need water to drill?

No - the slotted barrel design gives natural air cooling and clears debris, so it's designed for dry drilling.

Which sizes are available?

14 diameters, from 18mm up to 110mm, so you can match the bit to the hole size you need.

Will it fit my drill?

The M14 thread fits directly onto a standard angle grinder. For a high-speed corded drill, you'll need an M14-to-Hex adaptor (sold separately).

What materials can I drill?

Porcelain, ceramic tiles, stone tiles and stone worktops.

Is this suitable for professional use?

Yes - the XCEL-grade diamond edge and slotted barrel are built for regular use by tile installers and fitters, not just occasional DIY jobs.

How is the barrel different from a solid barrel bit?

The slots run the length of the barrel to aid cooling and clear cut debris as you drill, which helps prevent the bit overheating or clogging during dry use.

Can I use this on wall tiles as well as worktops?

Yes - it's suited to both wall/floor tile installation and thicker stone worktop drilling, provided you choose a diameter that matches the fixing you need.
