EXACT High Speed Steel Step Drill Bit 4 to 20 mm, Hex Shank, Titanium Aluminium Nitride Coated 4450067

EXACT 4450067 High Speed Steel Step Drill Bit is engineered to deliver precision drilling with a diameter range of 4 to 20 mm. Its step drill functionality enables users to efficiently bore multiple hole sizes in a single operation, making it ideal for industrial and workshop environments dealing with sheet metal, pipes, and profiles.

This drill bit is crafted from high speed steel (HSS) and equipped with a titanium aluminium nitride (TiAlN) coating. The TiAlN surface increases resistance to wear and heat, significantly extending the working life of the tool even when used in tough materials such as stainless steel, construction steel, and non-ferrous alloys.

The hex shank design offers secure mounting in the drill chuck, prevents slippage, and facilitates easy handling. A special two-edged straight tap geometry ensures burr-free drilling and planing, while eliminating the need for centre-punching. The drill bit stays true without running off the material surface, improving operator accuracy and safety.

Diameter specifications are lasered clearly on every step, allowing quick identification and repeat usability for fabricators. The three-faced driving shaft is designed to optimize power transmission, further reducing the risk of tool slip and providing reliable performance in professional environments.

EXACT 4450067 is recommended for use with construction steel, CrNi stainless steels, non-ferrous metals, Plexiglas, and plastics, and can handle wood applications up to 6 mm thickness. Its versatility makes it suitable for industrial, commercial, and laboratory settings where frequent material changes are common.

The overall build quality, advanced coating, and step-drill convenience make this bit a valuable choice for manufacturing, maintenance, HVAC, electrical, fabrication, and construction workshops.

Supports step drilling from 4 mm up to 20 mm diameter for versatile metalworking. Manufactured from high speed steel for enhanced performance and durability. Features a titanium aluminium nitride (TiAlN) coating for extended tool life, especially in tough materials.

Hex shank design prevents slippage in drill chucks and increases handling security. Suitable for burr-free drilling and planing in sheet metal, pipes, and profiles. No centre-punching required due to advanced tip geometry.
