Order LookupMetalworking Micro Drill Bits
Available3 products
Metalworking micro drill bits are small-diameter drill bits used for creating precise, tiny holes with close tolerances. The geometry and material of the bits provides optimal chip clearance when drilling into metal. The drill bits are used in handheld drills and machine setups such as drill presses.

AlCrN-Coated Spiral-Flute Solid Carbide Metalworking Micro Drill Bits
The AlCrN coating on these drill bits protects them from wear during dry, high-speed machining applications. It is harder, resists cracking and oxidization better, and performs better in high-feed applications than a TiAlN coating. It also resists high heat better than an AlTiN coating. Carbide micro drill bits provide excellent hardness, wear resistance, and heat resistance. They create precise holes with a smooth finish and often eliminate the need for reaming the hole after drilling. Carbide bits require a rigid setup such as a fixed-spindle machine. These bits have spiral flutes that evacuate chips as the bits drill into a workpiece.

EXO-Coated Spiral-Flute Solid Carbide Metalworking Micro Drill Bits
The EXO coating on these drill bits is a multilayered TiAlN coating with a very smooth finish. It resists wear better than a standard TiAlN coating. EXO-coated drill bits can be used at high speeds and withstand high temperatures. Carbide micro drill bits provide excellent hardness, wear resistance, and heat resistance. They create precise holes with a smooth finish and often eliminate the need for reaming the hole after drilling. Carbide bits require a rigid setup such as a fixed-spindle machine. These bits have spiral flutes that evacuate chips as the bits drill into a workpiece.
