Frequently Asked Questions

Are Sealey core drill bits suitable for wet and dry drilling?

Many Sealey core drill bits are designed for dry drilling applications, which is ideal for most building work. However, Sealey also offers specialist wet core bits for heavy-duty concrete drilling where water cooling extends bit life and improves cutting performance. Always check the specific product specifications to ensure you select the right bit for your application.

What diameter core bit do I need for standard UK pipework?

For 22mm copper pipe or 32mm waste pipe, a 35-40mm core bit provides adequate clearance. For larger 110mm soil pipes, you'll need a 120-130mm diameter bit. Sealey offers core bits in all standard sizes to accommodate common UK plumbing and electrical installations.

Can I use Sealey core drill bits with my existing power drill?

Sealey core drill bits are available with different shank types to suit various tools. SDS-plus bits require an SDS rotary hammer drill, whilst hex shank versions can be used with standard 240v drill drivers fitted with a suitable chuck. For best results and safety, always use the recommended power tool type for your chosen core bit.
