Micro Drill Bit Set 0.3 – 1.2 mm (10 Pieces)
Detailed Product Review
The precision of drilling operations in micro-machining processes is a critical determinant of the functional integrity and mechanical performance of the final product. This Micro Drill Bit Set includes 10 specific tools with nominal diameters ranging from 0.3 mm to 1.2 mm, designed to achieve high-tolerance hole geometries required in the production of miniaturized components. Each drill bit is manufactured based on principles of optimizing cutting edge geometry and maximizing chip evacuation dynamics. Parameters such as the cutting edge strength, thermal stability, and wear resistance of the set, management of radial and axial forces during machining, effective removal of micro-level chip formation, and minimization of hole wall surface roughness directly impact the overall performance of the tool. The ability to provide maximum hole accuracy and surface quality with minimal runout forms the basis for this set to deliver reliable and repeatable results even in applications requiring critical tolerances.
The tool components in this set are precisely machined from engineering materials such as High-Speed Steel (HSS) or Tungsten Carbide, selected according to specific application requirements. While HSS offers high toughness and impact resistance, Tungsten Carbide guarantees superior hardness and wear resistance with high-temperature performance. Material selection is optimized based on the properties of the material to be machined, such as hardness, abrasiveness, and thermal conductivity, to maximize tool life and machining efficiency. From electronic component assembly to medical device manufacturing, precision mold making, and optical systems, these micro drill bits can be seamlessly integrated into industrial automation systems. Standard cylindrical shank types ensure compatibility with the chucks of existing CNC machining centers and micro-drilling machines, allowing for quick tool changes and easy adaptation to the production line. Specially designed helix angles and cutting edge geometries provide optimal chip removal and heat management in different material groups, maximizing tool life while preserving the structural integrity of the machined part and preventing micro-crack formation.
Advantages of the Micro Drill Bit Set 0.3 – 1.2 mm (10 Pieces)
Precise Hole Geometry and Positional Accuracy: In micro-machining operations, hole diameter, circularity, cylindricity, and positional accuracy are critical for the final product’s assemblability and functional performance. These drill bits are designed with a precision that can narrow production tolerances down to the H7 class. Minimizing tool runout to micron levels reduces dynamic deviations at the cutting edge’s contact point with the workpiece, thereby minimizing deviations in hole geometry (taper, ovality). This is indispensable, especially in critical applications such as via holes on multi-layer printed circuit boards (PCBs) or micro-channels in medical implants, for optimizing electrical conductivity or fluid flow.
Advanced Material Composition and Surface Engineering: High-Speed Steel (HSS) or Tungsten Carbide-based tool materials are selected based on specific machining conditions to offer optimum mechanical properties. HSS minimizes tool breakage in vibrating cuts or interrupted feeds due to its high toughness, while the high hardness and compressive strength of Tungsten Carbide ensure long tool life even in abrasive materials. Optional PVD (Physical Vapor Deposition) coatings, such as Titanium Nitride (TiN), reduce the coefficient of friction of the tool surface, decrease cutting forces, prevent chip adhesion, and increase the tool’s thermal stability limits. These coatings keep the tool’s cutting edge temperature under control, significantly extending tool life and providing stable cutting performance even at high speed/feed rates.
