Drills

BB Tool drills cover CNC hole drilling, precision small-hole drilling, deep-hole drilling, and general metalworking applications. This drill range includes solid carbide drills, PRO carbide drills, micro drills, HSS and cobalt drills, center and spot drills, flat drills, step drills, indexable U drills, and friction drills.

Choose the right drill by workpiece material, hole diameter, hole depth, coolant method, machine rigidity, and hole geometry. Different BB Tool drill series are designed for different drilling conditions, including aluminum, copper, non-metal materials, steel, stainless steel, micro holes, flat-bottom holes, stepped holes, and deep-hole drilling where confirmed by the product specification.

Shop by Drill Type

  • Solid Carbide Drills: for CNC drilling with carbide rigidity and wear resistance.
  • PRO Carbide Drills: for higher-efficiency drilling, deeper hole ratios, and internal or external coolant options.
  • Micro Drills: for PCB, small-diameter, and precision micro-hole drilling.
  • HSS & Cobalt Drills: for general-purpose drilling and more flexible machine setups.
  • Center & Spot Drills: for accurate hole positioning, pilot preparation, and drill starting.
  • Flat Drills: for 180° flat-bottom holes, inclined surfaces, and curved surface entry.
  • Step Drills: for stepped holes, screw holes, and sheet or plate hole enlargement.
  • Indexable U Drills: for larger-diameter drilling with replaceable inserts.
  • Friction Drills: for thermal flow drilling and bushing-style holes in thin-wall materials.

How to Choose

  • By material: select aluminum/non-ferrous, steel, stainless steel, or special-material drill series according to the product specification.
  • By hole depth: choose regular, 3xD, 5xD, 8xD, 12xD, or 16xD drill options where available.
  • By coolant method: compare external cooling, internal coolant, and non-coolant-hole designs.
  • By hole geometry: choose spot drills, center drills, flat drills, step drills, U drills, or friction drills according to the required hole form.
