Plastic can melt, crack, or splinter if drilled incorrectly. Choosing the right drill bit — and using it at the right speed — makes all the difference. We’ve listed the three best options below, depending on your hole size and application.
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.
