Centre drill bits are short, rigid bits designed to create an accurately positioned starter hole in metal, ensuring precision when drilling to a larger diameter. Their stiff construction minimises wandering, making them ideal for use in lathes, milling machines, and drill presses where accuracy is critical.
Featuring a pilot tip and a wider countersink section, centre drill bits both locate the hole and create a chamfered entry to guide the following drill bit. They are essential for producing centred holes in workpieces for turning between centres, as well as for applications requiring precise alignment in machining and fabrication.
Made from high-speed steel (HSS) or carbide for strength and durability, centre drill bits are available in various sizes to suit different projects and machine setups.
