——
The overall hard alloy spiral drill bit is designed to be compact and typically features spiral cutting edges,
This helps to disperse cutting forces, thereby reducing stress on the workpiece and extending the tool's lifespan.
Its excellent infusion design and cutting geometry can achieve a smoother drilling process,
Capable of creating precise circular holes on the workpiece.
Hard alloy drill bit is a drilling tool made of tungsten carbide material. They provide the best combination of penetration and precision.
——
● The new chip groove shape takes into account the portability of the cutting edge, the rigidity of the tool, and the chip space.
● Professional coating post-treatment ensures low resistance and high efficiency processing.
● High quality hard alloy rod, DIN6537 fixed shank alloy drill bit, as long as it is within the specification range, the shank diameter is the same, saving the cost of drill chuck.

Drill bits come in different diameters and are suitable for different hole sizes and depths.
Generally speaking, drill bits with smaller diameters are more widely used. According to the size and specifications of the drill bit, there are micro diameter drill bits/3D/5D/8D. Wide chip grooves can improve chip removal, and corrugated blades can finely crush chips.
Small hard alloy drill bit - Dia1-2.9mm
Small hard alloy drill bits with a diameter range of 1mm to 2.9mm are precision cutting tools designed specifically for drilling small holes, with good accuracy and performance. These micro drills are made of high-quality hard alloy materials, known for their hardness, wear resistance, and durability.
Micro hard alloy drill bit 3D-Dia1-20mm
The length of a 3D micro diameter drill bit is three times its diameter. This means that when the depth of the hole is three times the diameter of the drill bit, a 3D micro hole drill bit is required. This type of micro diameter drill bit is suitable for applications that require relatively shallow micropores, such as electronics, medical devices, and micro mechanical fields.
Micro hard alloy drill bit 5D-Dia1-20mm
The 5D micro diameter drill bit is five times longer than its diameter. This type of micro diameter drill bit is suitable for relatively deep micropores, such as those used in aerospace, automotive manufacturing, and petroleum exploration applications. Due to its longer length, 5D microporous drill bits may require more consistent and precise machining equipment to ensure the quality and accuracy of the holes.
Micro hard alloy drill bit 8D-Dia3-20mm
The 8D micro diameter drill bit is eight times longer than its diameter. This is a micro diameter drill bit used for deep hole drilling tasks, typically for specific applications that require deeper holes. These applications may include certain aerospace components, microporous components of medical equipment, etc.
140 degree cutting edge drill bit suitable for hard materials
Low carbon steel, medium carbon steel, high carbon steel, alloy steel, quenched and tempered steel, quenched and tempered steel (45~50HRC), stainless steel, tool steel, cast iron, ductile iron, copper alloy, aluminum alloy castings, titanium alloy, nickel alloy, magnesium alloy (different models can be processed with different materials).
