Metal Drill bit (4mm)

Description

Achieve pinpoint accuracy and high-speed performance with the TOKOMA 4mm High-Speed Steel (HSS) Drill Bit. Engineered for the meticulous demands of metal fabrication and precision repair, this bit is designed to slice through tough materials with minimal friction. Its specialized geometry makes it the ideal tool for creating pilot holes, clearing paths for M4 fasteners, or detailed work in light-to-medium gauge metals.

Industrial HSS Construction: Forged from premium-grade High-Speed Steel, providing the thermal stability and hardness required to maintain a sharp cutting edge during high-RPM operations in dense metals.

Precision 4mm Diameter: The essential size for detailed mechanical work, electrical panel installations, and preparing surfaces for rivets or machine screws.

No-Wander Split Point Tip: Features a precision-ground 118° tip designed to bite into the surface instantly. This ensures an accurate start on contact without “skating” or wandering, even on curved metal surfaces.

Rapid Chip-Removal Flutes: Engineered with high-volume spiral flutes that efficiently eject metal shavings. This reduces heat buildup and prevents the bit from seizing or clogging during deep-hole drilling.

Multi-Material Versatility: Optimized for effortless drilling through mild steel, aluminum, brass, copper, and hard technical plastics.

Universal Straight Shank: Compatible with all standard 10mm and 13mm drill chucks, making it a versatile addition to any corded or cordless power drill kit.

Enhanced Fatigue Resistance: Professionally tempered to provide a balance of hardness and flexibility, significantly reducing the risk of snapping when encountering varied material densities.

Sharp precision. Cool operation. The professional standard for high-accuracy metal drilling.
