Drill Bits Built for Metal
Metal drill bits are precision tools designed to bore clean holes through various metals, including mild steel, stainless steel, aluminium, copper, and cast iron. The right drill bit ensures smooth, frustration-free results for any metalworking task.
Our range includes high-speed steel (HSS) bits for general use, black oxide-coated bits for added durability, and cobalt bits for hardened steels. Trusted brands like Sutton Tools deliver professional-grade performance for tradies and DIY enthusiasts alike.
When choosing a drill bit, consider the material. HSS bits are ideal for softer metals like aluminium, while cobalt bits (5-8% cobalt) excel at drilling stainless steel and hardened materials. Titanium-coated bits offer heat resistance and extended life for regular steel applications.
We stock drill bits in various sizes, from fine precision to larger diameters, in both metric and imperial measurements. Many feature split-point tips to reduce walking and ensure faster penetration, with 135-degree point angles optimized for metal drilling.
For best results, use cutting fluid, run drills at appropriate speeds (slower for harder metals), and apply steady pressure. Regular sharpening maintains performance and extends the life of your bits.
Frequently Asked Questions
What types of metal drill bits do you stock?
Our selection includes HSS bits for general drilling, cobalt bits for hardened and stainless steel, titanium-coated bits for durability, and black oxide bits for heat resistance. We offer individual bits, multi-piece sets, and specialty options like step drills and annular cutters.
Which drill bits are best for stainless steel?
Cobalt drill bits are ideal for stainless steel, offering superior hardness and heat resistance. They maintain their edge when drilling tough, work-hardening materials.
How do I know what size drill bit I need?
Drill bits are measured by diameter in metric (millimetres) or imperial (inches). Check project requirements or fastener specifications. Our sets include commonly used sizes for versatile applications.
