EXACT HSS Step Drill Bit 5 mm to 20 mm, Spiral Tap, TiAlN Coating, Model 05285

EXACT 05285 HSS Step Drill Bit is a specialist drilling tool engineered using high-speed steel (HSS) with a spiral tap and titanium aluminum nitride (TiAlN) coating to deliver exceptional durability and resistance to wear when cutting through tough materials.

This step drill bit is specifically designed to precisely cut holes in sheet metals, pipes, and profiles without burrs, making it ideal for construction steel, stainless CrNi steel, non-ferrous metals, plastics, plexiglass, and wood up to 5 mm thick. Its minimum head size is 5 mm and maximum head size 20 mm, providing versatility for various drilling tasks.

The TiAlN coating enhances the bit’s hardness and helps maintain sharpness, allowing longer service life even under heavy-duty use. Crosswise grinding removes the need for center-punching by preventing the bit from wandering on entry. The diameter guide is laser-etched into the tap to ensure clarity even during rotation, and the three-faced driving shaft ensures a firm grip in the drill chuck to avoid slipping and improve control.

Manufactured in Germany, the drill bit adheres to strict quality and production standards, although it does not have specific approvals or certifications. It is not suitable for aluminum drilling and should be used without cooling agents to maintain performance.

Constructed from high-speed steel (HSS) for durability and precision drilling. Features a minimum head size of 5 mm and a maximum head size of 20 mm for versatile applications. TiAlN coating enhances toughness and performance in demanding materials.

Designed for burr-free drilling and planing pipes, sheet metals, profiles, and moulding. Suitable for construction steel, CrNi steel, non-ferrous metals, plastics, plexiglass, and wood up to 5 mm thickness. Crosswise grinding eliminates the need for centre-punching; drill bits do not run during operation.

Diameter guide is laser-etched into the tap for legibility during rotation. Three-faced driving shaft prevents slipping in the drill chuck for secure fitting. Manufactured in Germany ensuring high-quality standards and performance.

Not suitable for aluminium and recommended for use without cooling agents.
