Performance That Stays Sharp Under Pressure

Tough materials demand serious tools. Sutton Jobber Cobalt Drills are built for precision under heat, maintaining sharpness & cutting speed where standard HSS bits fail. The cobalt blend boosts hardness, while the split-point tip prevents wandering on curved or hardened surfaces.

Trades across Australia rely on these drills for fabrication, automotive & construction projects. They pair well with Power Tools – Drills for everyday site work & with Grinders & Sanders when prepping or finishing metal surfaces. With smoother chip removal & better heat control, each bit delivers cleaner holes & faster results in any setup.

For the best finish, use Jobber Drill Sets to cover all size options, keep your gear maintained through Tool & Equipment Care Services & finish each job with the same precision these drills are built for. Upgrade your toolkit further with Hand Tools – Wrenches & Spanners for fastening & alignment, ensuring every project runs smoothly from start to finish.

► Cobalt-reinforced HSS design for heat resistance & long life
► Split-point geometry for fast starts & reduced wandering
► Ideal for stainless steel, hard alloys & general metal drilling
► Backed by Industrial Shed’s Same Day Dispatch & Trade Guarantee
