RUKO SPB-Set 25-Piece HSS Twist Drill Bit Set with TL3000 Coating, DIN 338, 1-13mm in Metal Cassette

This 25-piece HSS twist drill bit set features the advanced TL3000 multi-layer coating, delivering a hardness of approximately 3000 HV and heat resistance up to 800°C. The set includes all sizes from 1.0 mm to 13.0 mm in 0.5 mm increments, making it a comprehensive solution for precise drilling in high-alloy steels, stainless steel, cast iron, non-ferrous metals, and plastics.

Overview

The RUKO SPB-Set 25-piece HSS twist drill bit set is engineered for professional use. Each drill bit is ground from solid high-speed steel and finished with the TL3000 coating, which reduces friction and increases tool life. The split point design (DIN 1412 C) ensures accurate centering and reduces thrust requirements, while the 130° point angle is optimized for a wide range of materials. The set is supplied in a robust metal cassette for organized storage and easy transport.
