Drill bits and sets are essential cutting accessories designed for boring precise holes into masonry, metal, wood, and plastic. Using the correct bit for the substrate ensures clean finishes and prevents tool damage - helping you complete installations and fixings more efficiently.

High-speed steel (HSS) and cobalt drill bits for metal provide the heat resistance needed for tough alloys, letting you cut through stainless steel and cast iron without blunting the cutting edge. For heavy-duty building work, masonry and SDS bits are built to take the heavy pounding needed to drill into concrete and brick, clearing away dust and rubble quickly.
