Multi-Purpose Drill Bits

Multi-Purpose Drill Bits

Multi-purpose drill bits are designed to handle a range of substrates — steel, masonry, tile, timber, plastic — without swapping bits between materials. They're not a replacement for purpose-specific bits in serious production work, but for tradespeople, maintenance crews, and site work where the next hole could be in anything, multi-purpose bits save tool changes and toolbox real estate. AIMS Industrial stocks a curated range from Sutton Tools, Bordo, and Champion.

How multi-purpose bits work

The geometry combines features from masonry and metal-cutting drills. The tip carries a tungsten carbide insert (like a masonry bit) brazed onto a steel body with cutting flutes ground for general-purpose drilling. That combination gives enough hardness to bore through brick, tile, and lightly-reinforced concrete, while still cutting steel up to medium carbon grades and timber without burning.

Where they earn their place

• Maintenance work — fixing brackets, signs, and accessories where the wall could be steel, brick, or timber stud
• Service vans — one set of bits covers most fasteners encountered on site
• Light fitouts — drilling pilot holes through mixed substrates without bit changes
• Tile and bathroom work — boring through ceramic tile into plaster or masonry without cracking the tile

Where to use a dedicated bit instead

For production work in a single material, a purpose-specific bit cuts faster and lasts longer. HSS jobber drills for steel, masonry bits for concrete, tungsten carbide-tipped for tile — each is optimised for its material. Multi-purpose bits are the right choice when material variety, not volume, is the issue.

Sizes and packs

Multi-purpose bits are stocked in metric sizes from 3mm to 13mm in singles and assorted sets. Sets typically cover the most-used sizes (4, 5, 6, 7, 8, 10mm) in a hard case for site work. Singles let you replace the size that's seen the most use.

Drilling practice

Run at low to medium RPM (carbide tip doesn't like high heat), use light pressure, and lubricate with cutting fluid for steel work. For tile, start with a slow RPM and a centre-punched mark to prevent skating. For masonry, hammer-drill mode helps speed but isn't always necessary on lighter substrates.
