HSS & Metal Bits
Discover our range of HSS drill bits and metal drill bits from Dormer, DEWALT, Irwin, Faithfull, Starrett, BlueSpot Tools and Trend, covering jobber drills, cobalt drill bits, TiN coated bits and step drill bits from 1mm up to 34mm diameter.
HSS (high speed steel) bits are the standard choice for drilling metal, giving better heat resistance and edge retention than standard carbon steel. Coatings and alloys extend this further: cobalt content adds heat resistance for stainless steel and hardened alloys, while TiN (titanium nitride) coating reduces friction and extends bit life in general steel and aluminium work.

HSS & Metal Bits – Product list
Standard HSS jobber drills
Jobber drills are the everyday general-purpose metal drill bit, with Dormer's A100 and A002 ranges forming the backbone of this collection. The A100 HSS Jobber Drill covers standard diameters, while the A002 HSS-TiN Coated Jobber Drill range, covering diameters from around 6.5mm up to 13mm, adds a titanium nitride coating for extended tool life in repeated steel drilling. Faithfull's Long Series HSS Jobber Drills give extended reach beyond standard jobber length for deeper drilling needs.
Cobalt drill bits for hard metals
Cobalt drill bits handle stainless steel and other hard, heat-generating materials that standard HSS bits struggle with over repeated use. The Faithfull Professional Cobalt Jobber Drill Bit range and Irwin's HSS Cobalt Drill Bit range, including the 15 Piece Set, give better heat resistance and edge retention than standard HSS when drilling stainless steel, cast iron and other demanding alloys.
TiN coated and titanium bits for extended life
Irwin's HSS Pro TiN Coated range and the HSS Titanium Metal Drill Bit Set (13 Piece) reduce friction at the cutting edge, extending bit life in general steel, aluminium and non-ferrous metal drilling compared to uncoated HSS. This coating matters most for regular, repeated drilling where bit replacement cost adds up over time.
Imperial and metric HSS drill sets
For workshops needing a full range of sizes on hand, Dormer's metric sets, such as the A191 No.419 Metric HSS Drill Set (19 pieces, 1.0-10.0mm) and A094 No.413 TiN Coated Set (13 pieces), cover common diameters at 0.5mm increments. The imperial A190 No.20 Imperial HSS Drill Set (15 pieces, 1/16-1/2in) serves work still specified in imperial measurements. DEWALT's DT20620 BLACK&GOLD range and Makita's D-54097 25 Piece Set give broad general-purpose coverage for workshops and site kits.
Step drill bits for sheet metal
Step drill bits cut a range of hole diameters with a single tool, ideal for thin sheet metal and electrical panel work where multiple exact hole sizes are needed without carrying a full set of standard bits. DEWALT's Extreme Step Drill Bit range, from the compact 6-12mm up to the 20-34mm, covers small to large diameter progressions, alongside Faithfull's HSS Step Drill Bit range and the compact BlueSpot Tools 1/4in Hex Shank Step Drill for use directly in an impact driver.
Hex shank bits for impact driver use
Standard round-shank HSS bits can slip in an impact driver's hex chuck under load. Irwin's HSS Drill Bit Hex Shank range and DEWALT's BLACK&GOLD Hex HSS-G Drill Bit range are built with a hex shank specifically for secure impact driver use, giving the drive positive grip without needing a separate keyless chuck adapter.
Blacksmith's and heavy-duty large diameter bits
For larger diameter, heavier-duty metal drilling, the Faithfull Blacksmith's M2 HSS Professional Drill Bit range covers larger diameters, such as 20mm and 25mm, built from M2 high speed steel for demanding, sustained metalworking use beyond typical jobber drill capacity.
Choosing the right bit type
Match bit type to material and use: standard HSS jobber drills suit general mild steel drilling, cobalt bits handle stainless steel and hard alloys, TiN coating extends life for repeated general use, step drills solve thin sheet metal work with fewer tool changes, and hex shank bits suit impact driver use specifically.
