Jobber Drill Bit Set Selection — Quick Reference
Jobber drill bit sets = STANDARD WORKSHOP drill bit kits — DIN 338 length (~7-10× diameter). Workshop + maintenance + service van + production starter kit. Metric + imperial + cobalt + coated options.
| Jobber Set Type | Best For |
|---|---|
| Metric Jobber Set (1-13mm) | Standard workshop range |
| Imperial Jobber Set (1/16-1/2") | US-origin + workshop |
| Number Drill Set (#80-#1) | Small precision + tap drills |
| Letter Drill Set (A-Z) | Larger precision + UNC tap drills |
| HSS Standard | Mild + low-alloy steel |
| HSS Cobalt | Stainless + tough alloys |
| TiN-Coated | Extended life |
| Solid Carbide | Production + extended |
| Indexed Case (Slot per Size) | Workshop organisation |
Critical: Workshop starter = metric 1-13mm + imperial 1/16-1/2" + number + letter (~115 bits total). Indexed case = quick size identification. Brands: Sutton Tools, Bordo. Companion: jobber drill bits, drilling, drill bit size chart.
Jobber Drill Bit Sets
AIMS Industrial stocks jobber drill bit sets in metric and imperial sizes for general workshop, CNC, maintenance and construction drilling. Our comprehensive range from Sutton Tools, Saber, Bordo and Pferd covers HSS, HSS-Co cobalt and TiN-coated sets in sizes from 1 mm to 25 mm for drilling steel, stainless, cast iron and non-ferrous materials.
Jobber Drill Set Types
- HSS jobber sets: Standard high-speed steel — suitable for mild steel, aluminium, copper, brass and plastics in most workshop and maintenance applications.
- HSS-Co cobalt sets: 5% or 8% cobalt-enhanced HSS for harder alloy steels, stainless steel and work-hardening materials where standard HSS wears prematurely.
- TiN-coated sets: Titanium nitride coating improves surface hardness, reduces friction and increases drill life in steel, aluminium and composite materials.
- TiAlN-coated sets: High-performance PVD coating for dry or minimum-quantity lubrication drilling in hardened steel, cast iron and exotic alloys.
- Split-point sets: 135° split point geometry self-centres on flat surfaces, reduces feed force and eliminates walk in CNC drilling without a centre punch.
Set Size Range Selection
- 1–6 mm sets: Essential for PCB drilling, small tapping pilots, instrument work and fine metalwork in toolroom and electronics manufacturing.
- 1–10 mm or 1–13 mm sets: The most popular general workshop set — covers the majority of tapping, clearance and through-hole drilling in standard metal fabrication.
- 1–25 mm sets: Comprehensive maintenance and toolroom sets for facilities requiring the full diameter range without changing to a hole saw or annular cutter.
- Set case quality: Indexed plastic cases with individual drill grooves prevent damage and enable rapid size selection — preferable to cloth pouches in production environments.

People Also Ask — Jobber Drill Bit Sets
Q: What does "jobber length" actually mean for a drill bit?
It refers to the DIN 338 standard length, roughly 7 to 10 times the bit's diameter — the standard general-purpose proportion, as opposed to short/stub or extra-long bits built for specific reach requirements.
Q: What's the difference between a number drill set and a letter drill set?
Number sets run from #80 to #1 for small precision work and tap-drill pairing on fine threads. Letter sets run from A to Z for larger precision work and UNC tap-drill sizes — the two ranges cover different size bands for different precision and tap-drill needs.
Q: What does split-point geometry actually do that a standard-point jobber bit doesn't?
A 135° split point self-centres on flat surfaces, reduces feed force, and eliminates walk in CNC drilling without needing a centre punch first — a standard point is more prone to wandering before it bites.
Q: When would a 1-25mm comprehensive drill set be worth it over a standard 1-13mm workshop set?
A 1-25mm set suits facilities needing the full diameter range without switching to a hole saw or annular cutter for larger holes. A 1-13mm set covers the majority of everyday tapping, clearance and through-hole drilling that most workshops actually do.
Q: What's the practical benefit of an indexed case over a cloth pouch for a drill bit set?
Individual grooves in an indexed case prevent bit damage and enable rapid size selection — preferable to cloth pouches in production environments where speed and keeping the set organised both matter.
