RS PRO 51-Piece HSS Twist Drill Bit Set for Metal, Sizes 1 mm to 6 mm, 0.1 mm Increments 668-0992

RS PRO 668-0992 51-Piece HSS Twist Drill Bit Set for Metal delivers a comprehensive range of high-speed steel bits designed for precision metal drilling tasks. The set spans sizes from 1 mm to 6 mm in fine 0.1 mm increments, ensuring versatile utility across diverse metal drilling requirements.

Crafted from a single piece of high-speed steel (HSS), these bits resist breaking and blunting, even under high stress or temperature conditions. Manufactured following DIN 338 standards, they guarantee superior geometric accuracy and precision tolerance, essential for professional metalworking.

The bits feature a ground flute that extends tool life beyond that of equivalent roll forged bits. A black oxide finish assists rapid material removal while offering added corrosion resistance. The shaft diameter is perfectly matched to the drill bit diameter, greatly reducing breakage risk during use.

While primarily intended for non-ferrous metals such as aluminium, copper, brass, zinc, and iron, these drill bits can also be deployed on plastic, wood, and masonry with anticipated performance adjustments.

The set contains 51 HSS drill bits ranging from 1 mm to 6 mm by 0.1 mm increments. Ideal for use in industrial, manufacturing, workshop, HVAC, and general metal fabrication settings. High resistance to heat and stress ensures durability in demanding drilling operations.

DIN 338 compliance guarantees professional-grade manufacturing quality. Black oxide finishing and ground flute design optimize cutting efficiency and longevity.

This RS PRO drill bit set is a reliable addition for professionals and hobbyists requiring a wide size range of durable, precise drill bits suitable for metalworking and related applications. Explore an extensive category selection for Drill Bit Sets and industrial tooling at EnvMart.
