    • Multiple product options available

      These micro drill bits allow precise small diameter and close tolerance metalworking applications. Heat-resistant solid carbide offers greater rigidity than high speed steel.

      Multiple product options available

  • Solid Carbide Micro Drill Bits, EXO Finish
    • Multiple product options available

      Micro drill bits allow precise small diameter and close tolerance metalworking applications. Heat-resistant solid carbide offers greater rigidity than high speed steel. EXO nickel boron finish helps to reduce friction and increase wear resistance.

      Multiple product options available

  • Solid Carbide Micro Drill Bits, AlTiN Nano Finish
    • Multiple product options available

      These micro drill bits allow precise small diameter and close tolerance metalworking applications. Heat-resistant solid carbide offers greater rigidity than high speed steel. AlTiN nano finish maintains wear-resistance, low friction, and low thermal conductivity at high temperatures where these properties degrade in other coatings.

  • Solid Carbide Micro Drill Bits, AlTiN Finish
    • Multiple product options available

      Micro drill bits allow precise small diameter and close tolerance metalworking applications. Heat-resistant solid carbide offers greater rigidity than high speed steel. AlTiN finish maintains wear-resistance, low friction, and low thermal conductivity at high temperatures while these properties degrade in other coatings.

      Multiple product options available

  • Carbide-Tipped Micro Drill Bits, Uncoated Finish
    • Multiple product options available

      These micro drill bits allow precise small diameter and close tolerance metalworking applications. Carbide-tipped bits stay sharp longer than steel. Uncoated bits can be sharpened without damaging any finish.

      Multiple product options available

  • Solid Carbide Micro Drill Bits, Altima Finish
    • Multiple product options available

      These micro drill bits allow precise small diameter and close tolerance metalworking applications. The heat-resistant solid carbide offers greater rigidity than high speed steel. The ALtima® coating adds strength, making these bits suitable for use on difficult-to-machine materials, such as hardened steel and titanium alloy.

      Multiple product options available

  • Solid Carbide Micro Drill Bits, TiCN Finish
    • Multiple product options available

      Micro drill bits allow precise small diameter and close tolerance metalworking applications. Heat-resistant solid carbide offers greater rigidity than high speed steel. TiCN finish is harder and more wear-resistant than many other coatings.

      Multiple product options available

  • Solid Carbide Micro Drill Bits, AlCrN Finish
    • Multiple product options available

      These micro drill bits allow precise small diameter and close tolerance metalworking applications. Heat-resistant solid carbide offers greater rigidity than high speed steel. AlCrn finish is ideal for difficult-to-cut tough alloys in which the chips are longer.

      Multiple product options available

  • High Speed Steel Micro Drill Bits, Uncoated Finish
    • Multiple product options available

      Micro drill bits allow precise small diameter and close tolerance metalworking applications. Made of heat-resistant, long-lasting high speed steel, they're capable of cutting through extremely hard materials. Uncoated bits can be sharpened without damaging any finish.

      Multiple product options available

  • Cobalt Steel Micro Drill Bits, Bright Finish
    • Multiple product options available

      Micro drill bits allow small diameter and close tolerance metalworking applications. Cobalt steel material is great for drilling into harder steel as well as stainless steel grades. The bright finish is smooth and polished, which is great for use on aluminum.

      Multiple product options available

  • Cobalt Steel Micro Drill Bits, TiN Finish
    • Multiple product options available

      These micro drill bits allow precise small diameter and close tolerance metalworking applications. Cobalt steel material is great for drilling into harder steel as well as stainless steel grades. TiN finish on these bit allows you to run the drill faster than uncoated bits to increase tool life.
