Drill Sets - Pre-Packed Jobber Drill Bit Sets

Pre-packed jobber drill bit sets for the workshop and field. Sets remove the buy-by-the-piece work of building a kit - one purchase covers the full common size range. Common piece counts: 13-piece (1-13mm metric), 19-piece, 25-piece (1-13mm + half-mm increments), 29-piece, plus imperial sets in fractional sizes.

Metal-cutting bits are the workshop default - HSS (High Speed Steel) or HSS Cobalt. Cobalt sets handle stainless and hardened steels without dulling the cutting edge. Both work in steel, non-ferrous metals and timber.

Brands stocked at BNA: Alpha (Sheffield Group), Sutton Tools (Australian), Bristol (UK).

Pair with individual Jobber Drill Bits when you need to replace a single size from the set, or Molyslip cutting compound to extend bit life on stainless and hardened materials.

What size range should I pick for a general set?

13-piece (1-13mm in 1mm increments) is the everyday metric set - covers most fastener sizes you'd ever drill. 25-piece adds half-mm increments for fine-tolerance work. 29-piece adds the smaller sub-mm sizes for sheet-metal pilot holes.

HSS or HSS Cobalt set?

HSS is fine for general steel and timber. HSS Cobalt costs more but handles stainless and hardened steels - keeps the cutting edge longer on tough materials. For mixed-material workshop work, the Cobalt set is the better long-term investment.
