Dormer A0024.7 drill bit set features 5 pieces of high-speed steel drill bits, each with titanium nitride (TiN) coating and 4 helical flutes. These industrial-grade drill bits measure 80mm overall length with a 47mm drilling length and a 4.7mm cylindrical shank suitable for both hand and machine use.

The 118° split-point drill tip ensures accurate hole positioning and efficient cutting performance. TiN coating extends tool life by improving wear resistance, especially when drilling harder materials like steel, cast steel, grey and malleable cast iron, aluminium alloys, plastics, and graphite.

This set complies with DIN 338 RN, BS 328, and ISO 235 standards, assuring quality and performance. The drill bits' helical flute design has been optimized for stiffness and enhanced chip removal, enabling drilling up to 4 times the drill diameter in various materials with ease.

These drill bits are marked with clear size engravings for convenience and quick identification on-job. The right-hand cutting direction combined with a cylindrical shank provides stable and accurate drilling operations in industrial, mechanical, construction, and laboratory use cases.

Note that these are jobber length drill bits, longer than mechanic types, making them well suited for deeper drilling tasks. The set is made in Brazil and packaged containing 5 drill bits, ideal for professionals requiring reliability and durability.
