Industrial-grade imperial twist bits for quick, scalable workshop replenishment.
Sutton Tools Blue Bullet Imperial Jobber Drills provide maximum cutting efficiency for continuous machine and hand-held trade operations. Available in loose individual fractional size replacements from 1/16″ up to 1/2″ (including micro sizes like 3/64″), these premium M2 High-Speed Steel (HSS) engineering bits feature a protective blue steam oxide coating that aggressively lowers friction and prevents chip welding when boring tough structural metals. 
  • Custom Selection: Purchase precise fractional imperial replacement sizes to restock your active trade drill indexes.
  • High-Thermal Integrity: Premium European M2 HSS core maximizes tool life and resists edge fatigue under continuous loads.
  • Friction & Wear Reduction: Blue steam oxide treatment keeps flutes lubricated and reduces overall drilling heat.
  • Anti-Wander Drilling: Precision 118° web-thinned split point cuts immediately on contact without slipping

Professional Fractional Imperial Jobber Drill Bits

Streamline your engineering shop or service rig replenishment with the Performance Blue Bullet series by Sutton Tools. Rather than purchasing an entire indexed drill set when highly repeated sizes break or go dull, these high-performance loose straight-shank bits allow fabricators, maintenance fitters, and machinists to restock precisely the diameters they use daily. 
Key Engineering Features for the Trade
  • Steam Oxide Blue Coating Finish: The specialized porous surface treatment holds onto drilling compounds and cutting lubricants tightly. This significantly reduces friction drag and lowers work-hardening risks when drilling through low-carbon steel plates or structural beams. 
  • Accurate Hole Sizing Tolerances: Manufactured to precise engineering standards using a precision ground parallel straight shank. This guarantees structural concentricity and absolute safety across hand drills, drill presses, and magnetic bases. 
  • Rapid Swarf Clearing Performance: Optimized spiral flute geometry smoothly forces hot metal shards and steel spiral chips up out of deep blind holes, keeping binding or binding-related breakages to an absolute minimum.

Recommended Trade Applications & Materials
  • Ferrous Metals & Mild Structural Steel Sections
  • Cast Iron, Carbon Steels, and Low-Alloy Structural Metals
  • Non-Ferrous Metals, Aluminum Sheet, Brass, and Tough Engineering Plastics
