Features:

Comprehensive Size Range: This 20-piece micro drill bit set includes graduated sizes from 0.3mm through 1.6mm, covering the most frequently used diameters for precision work. The incremental progression includes 0.3, 0.35, 0.4, 0.45, 0.5, 0.55, 0.6, 0.65, 0.7, 0.75, 0.8, 0.85, 0.9, 0.95, 1.0, 1.2, 1.3, 1.4, 1.5, and 1.6mm. This variety ensures the right bit for every miniature drilling application

Material: Manufactured from high-speed steel, these twist drills deliver exceptional hardness and heat resistance for extended cutting life. Micro drill bit HSS composition maintains sharpness through repeated use in wood, plastic, and circuit board materials. Professional-grade metallurgy ensures clean, accurate holes without premature dulling or breakage

CNC Precision Grinding: Each drill bit undergoes precision CNC machining to achieve exacting dimensional accuracy and consistent cutting geometry. Mini drill bit computer-controlled grinding creates symmetrically ground flutes for balanced rotation and efficient chip evacuation. Micro drilling bit manufacturing precision results in straight, burr-free holes in delicate materials

Organized Storage Case: Supplied in a specially designed box that securely holds each bit in an individual compartment, preventing damage and loss. Miniature drill bit transparent lid allows instant visual identification of the correct size without opening. Compact storage keeps your micro drill set organized and portable for workshop, bench, or field use
