Solid carbide twist drills are cutting tools designed to create precise round holes in workpieces.
Solid carbide spiral drill bits feature a compact design with a helical cutting edge that helps distribute cutting forces, reducing stress on the workpiece and extending tool life. Their advanced design and cutting geometry ensure a smoother drilling process, allowing for precise, round holes in the material.
Carbide Drill Bits Production Process
Carbide drill bits, made from tungsten carbide, which could offer an optimal balance of precision and penetration for drilling tasks.
● Optimized flute design balances cutting edge lightness, tool rigidity, and chip clearance.
● Advanced coating treatment ensures low-resistance, high-efficiency machining.
● Made from high-quality tungsten carbide with a DIN6535HA fixed shank, offering consistent shank diameter across specifications, reducing drill chuck costs.
Drilling Parameters
Drills come in different diameters for different hole sizes and depths.
Smaller diameter drills are commonly used and come in various lengths such as 3D, 5D, and 8D. Features include wide chip flutes for better chip evacuation and corrugated blades for efficient chip breaking.
- Small Carbide Drill Bits-Diameter 1-2.9mm
Carbide drill bits with diameters of 1mm to 2.9mm are precision tools designed for accurate small-hole drilling. Made from high-quality carbide, they offer excellent hardness, wear resistance, and durability.
- Micro Carbide Drill Bits 3D-Diameter 1-20mm
- Micro Carbide Drill Bits 5D-Diameter 1-20mm
- Micro Carbide Drill Bits 8D-Diameter 3-20mm
8D Micro Diameter Drill Bits are eight times their diameter, designed for deep hole drilling in applications such as aerospace components and micro-hole assemblies in medical devices.
