Ten Piece Incremental Size Carbide Drill Sets

Shop 10-piece incremental size carbide drill bit sets for precision drilling, PCB work, CNC use, plastics, composites, model making, hobby drilling, and small-hole applications. These sets group nearby drill diameters together so you can keep a useful range of sizes on hand.

Each set includes multiple solid carbide micro drill bits with standard 1/8" shanks. These incremental drill sets are useful when you need several close sizes for test fitting, prototyping, repair work, production setup, or fine adjustment.

Why Choose an Incremental Carbide Drill Set?

  • Nearby size ranges: Good when you need several close drill diameters instead of one exact size
  • Solid carbide construction: Useful for precision drilling in PCB materials, plastics, composites, brass, aluminum, and other appropriate materials
  • 1/8" shank: Fits many PCB drill holders, CNC collets, rotary tools, and precision drilling setups
  • Small quantity sets: Practical for hobby use, prototyping, repair work, and backup tooling

Common Uses

  • PCB and circuit board drilling
  • Electronics prototyping and repair
  • Model making and hobby machining
  • Small-hole drilling in plastics, composites, brass, aluminum, and similar materials
  • Testing nearby hole sizes before choosing a final drill diameter
