EXACT 3-Piece Step Drill Bit Set for Metal 4 mm Min, 30 mm Max, HSS Material 05331

EXACT 05331 3-Piece Step Drill Bit Set is crafted with high-speed steel (HSS) and designed for professional metal drilling including construction steel, CrNi steel, and other metals. It covers hole sizes from 4 mm minimum up to 30 mm maximum, ensuring versatility for various industrial and workshop applications.

The step drill bits feature a straight tap and two cutting edges to facilitate burr-free drilling and smooth planing of sheet metals, pipes, and profiles without the need for centre-punching. This results in enhanced precision and efficiency during drilling operations.

Thanks to the laser-etched diameter markings on every step, maintaining hole size accuracy is straightforward. The three-faced shaft prevents slipping in the drill chuck, improving safety and operational control.

This set is ideal for use in construction sites, metal fabrication workshops, manufacturing plants, and laboratories where precision metalworking is critical. The bits perform well on non-ferrous metals, plastics including Plexiglas, and wood materials up to 6 mm thickness, broadening application possibilities.

The bits are housed in a protective plastic case, providing secure storage and easy transport. Manufactured in Germany, this drill bit set conforms to high standards of quality and durability, making it a reliable choice for industrial professionals and technicians.

The set contains three step drill bits made from durable high-speed steel. Designed for burr-free drilling and planing of sheet metal, pipes, and profiles. No centre-punching required as drill bits do not run during use.

Suitable for construction steel, CrNi steel, non-ferrous metals, Plexiglas, plastics, and wood up to 6 mm thickness. Diameter sizes are laser etched on each level for easy identification. The three-faced driving shaft design prevents slipping in drill chucks.
