HSS GROUND Pro Jobber Drill Bit – M2 – Imperial & Metric

The HSS ground jobber drill bit is one of those tools that sits quietly in every tradesperson’s kit, doing the work without any fuss. This M2 grade bit is ground to a 135-degree split point from 3mm and above, which means no centre punching, no wandering, and no pre-drilling faff. Line it up, pull the trigger, and it goes where you put it. That matters when you’re drilling twenty holes in a morning rather than two.

Black oxide finish helps with heat resistance and gives a degree of corrosion protection during storage and use. The bits are roll forged and manufactured to DIN338, which is the standard specification for jobber-length twist drills — so you know what you’re getting in terms of length-to-diameter ratio and overall geometry. Nothing exotic, just a solid, properly made bit that performs consistently across the size range.

Where the HSS Ground Jobber Drill Bit Earns Its Keep

This is a general-purpose drill bit for non-alloy materials: mild steel, aluminium, brass, copper, timber, sheet materials and most plastics. It handles the day-to-day without complaint. The split point geometry is particularly useful when drilling curved or sloped surfaces where a standard 118-degree tip would skate about until it finally bites. From 3mm upward, it self-centres on contact.

Available in both metric and imperial sizes, which is more useful than it sounds. Plenty of jobs still call for fractional imperial sizing, particularly when working to older specifications or matching clearance holes to imperial-threaded fixings. Having both systems available from a single product range avoids the need to keep two separate sets on the van.

Build Quality and Material Grade

M2 is the standard high-speed steel grade for general workshop and site use. It holds a good edge under normal working temperatures and is tough enough for intermittent use without snapping under side load. Ground bits produce a cleaner hole than rolled-only alternatives, which matters when tolerance is tight or surface finish counts. These are not cobalt bits and are not intended for hardened steels or stainless, but for the vast majority of drilling tasks on a typical job, they do exactly what’s needed.
