Metalworking Micro Drill Bits
Available360 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.
Primary Material Application
Coolant-Through AlTiN-Coated Spiral-Flute Solid Carbide Metalworking Micro Drill Bits
The AlTiN coating on these drill bits protects them from wear when drilling hard and abrasive materials and is more resistant to high heat than a TiAlN coating. These drill bits have holes that allow coolant to flow to their tip to reduce heat and help clear chips during drilling. 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. Spiral-flute drill bits evacuate chips as the bits drill into a workpiece.

Bright Finish Spiral-Flute High-Speed Steel Metalworking Micro Drill Bits
High-speed steel micro drill bits provide more flexibility and absorb more shock and vibration than cobalt and carbide micro drill bits, making them suitable for use in manual drilling machines and handheld power tools. They may leave a rough finish on the hole. The bright finish on these drill bits is not affected when the bits' cutting edges are resharpened. Spiral-flute drill bits evacuate chips as the bits drill into a workpiece.

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.

SS-Coated Spiral-Flute Solid Carbide Metalworking Micro Drill Bits
The SS coating on these drill bits is harder than a TiCN coating and withstands high temperatures. It protects the bits from abrasion and wear when drilling steel, stainless steel, and heat-resistant alloys. 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.

Metric AlTiN-Coated Spiral-Flute Solid Carbide Metalworking Micro Drill Bits
These drill bits come in standard sizes expressed in millimeters. The AlTiN coating on these drill bits protects them from wear when drilling hard and abrasive materials and is more resistant to high heat than a TiAlN coating. These bits do not have coolant holes, so a separate hose is required to bring coolant to the bits' tip if it is needed. 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.

Left-Hand Bright Finish Spiral-Flute High-Speed Steel Metalworking Micro Drill Bits
These bits have a left-hand drilling direction and can be used in reverse-drilling applications to remove broken screws from a hole. High-speed steel micro drill bits provide more flexibility and absorb more shock and vibration than cobalt and carbide micro drill bits, making them suitable for use in manual drilling machines and handheld power tools.
