Steel

Our go-to for most steel jobs, ground HSS with a 135° split point ensures clean starts, less wander, and lasting performance. Also sharp and reliable for plastics like uPVC and ABS. For harder steels and stainless, cobalt alloys (M35/M42) offer better heat resistance and edge retention. Run slowly with light pressure and keep bits cool for best results.

Designed for cutting large-diameter holes in steel, plastic, and wood — including sheet metal, trunking, junction boxes, and panels. Best used at slow speed with steady pressure to avoid heat build-up, melting, or snagging. Ideal for wide openings in worktops, cladding, or electrical fittings.

Ideal for larger holes or use with high-torque drills

Tungsten carbide-tipped bits for when cobalt isn’t enough. Ideal for extreme materials like high-tensile fasteners, hardened bolts, and heavy-duty security plates. Often used by locksmiths, fabricators, and engineers. Requires precision and care.

For smooth, precise holes in reinforced or high-density materials. Typically used with core drilling machines — ideal for structural work or high-finish installs.
