HSS Roll Forged Jobber Drill Bit Sets – Timco

The Timco HSS roll forged jobber drill bit set is the kind of thing you reach for daily without thinking about it — and that’s exactly how it should be. Available in a 19-piece set covering 1–10mm and a 25-piece set covering 1–13mm, these are solid, no-nonsense HSS-R bits suited to general drilling across non-alloy materials. Steel, timber, aluminium, plastics — the sort of everyday drilling that makes up most of a working day on site or in the workshop.

Roll forging gives each bit a consistent, accurate geometry that you just don’t get with cheaper pressed alternatives. The blank is shaped under pressure rather than cut, which refines the grain structure and produces a bit that holds its edge noticeably longer under normal use. It’s not glamorous engineering, but it makes a real difference when you’re halfway through a run of holes and the last thing you need is a blunt bit wandering off centre.

The 135° Split Point on These Timco Jobber Drill Bits

The 135° split point is worth paying attention to. A conventional 118° point needs a centre punch to stop it skating across a smooth surface before it bites. The tighter split point on these Timco bits self-centres on contact, so you can get straight into the material without marking up first. Faster to use, fewer steps, less aggravation. On a job where you’re drilling dozens of holes in steel plate or aluminium sheet, that adds up quickly.

Sizing the Set to Your Work

The 19-piece set is fine for most general trades work — if you rarely need anything above 10mm, there’s no point carrying a bigger case. The 25-piece set extends to 13mm and suits anyone working regularly with larger fixings, conduit, or structural timber where a broader size range earns its place in the bag. Both sets are priced at the kind of level where buying a spare set makes sense rather than being a luxury.

As jobber-length bits, they strike a practical balance between reach and rigidity. Long enough for most applications, short enough to stay accurate without flex. If you’re drilling deep-section steel or need extended reach, you’d want specialist bits — but for the vast majority of day-to-day drilling, this Timco HSS roll forged jobber drill bit set covers the ground.
