Match the bit to the material, not just the size. HSS bits suit metal and general use, masonry bits are tipped for concrete and brick, and wood bits such as spade or auger types are designed to clear timber waste efficiently. Using the wrong bit type wears out faster and gives a rougher hole.
Frequently Asked Questions
What is the difference between HSS and cobalt drill bits?
HSS bits suit general metal and wood drilling, while cobalt bits are alloyed for extra heat resistance and hold an edge longer on harder metals such as stainless steel.
What drill bit do I need for concrete or brick?
A masonry bit with a tungsten carbide tip is required, standard HSS bits will blunt quickly on masonry.
Can I use a wood bit on metal?
No, wood bits are designed to clear soft material quickly and will blunt or break on metal, use an HSS or cobalt bit instead.
What size drill bit set should I buy for general use?
A set covering 1mm to 10mm in HSS covers most general wood and metal drilling, add masonry sizes separately if you drill into brick or concrete regularly.
Do you stock SDS drill bits as well as standard bits?
Yes, we stock SDS Plus and SDS Max bits for rotary hammer drills, alongside standard round shank bits.
Can you source a specific drill bit size not listed?
Yes, tell us what you need and we will try to source it for you.
