This high-quality, 19-piece HSS-Co (High-Speed Steel alloyed with Cobalt) screw tap drill bit set has been developed for precise drilling tasks, especially for automotive body repair work and general metalworking applications. The drill bits comply with the strict DIN 338 standard, ensuring consistent quality and performance.
The screw tap drill bits included in the set feature a cylindrical shank, which is ideal for machine chucking, ensuring stable and vibration-free operation. The material of the drill bits is HSS (High-Speed Steel), enhanced with cobalt, which significantly increases the tools' wear resistance and service life, especially when machining harder materials.
In terms of surface treatment, the drill bits are available in a bright or steam-tempered finish, which further enhances durability and reduces friction during drilling.
Design and Geometry:
Type: Type N design, suitable for universal applications.
Cutting Direction: Right-hand cutting design.
Point Angle: 118° point design, enabling optimal centering and precise cutting.
Edges: Each drill bit is equipped with two cutting edges, resulting in efficient material removal and a clean hole surface.
The set is the ideal choice for anyone looking for reliable, long-lasting tools capable of handling various metal materials.
The 19-piece set covers a comprehensive range of sizes that satisfy most common drilling requirements. The sizes follow each other in increments of 0.5 mm, guaranteeing precise size selection.

The HSS-Co drill bits are highly resistant to high temperatures due to their cobalt content, which is essential for high-speed drilling or when machining difficult materials.
Main Advantages:
Increased Lifespan: The cobalt alloy ensures a longer lifespan for the tools compared to traditional HSS drills.
Precise Holes: The 118° tip geometry and manufacturing according to DIN 338 standards guarantee precise dimensional accuracy.
Versatility: Suitable for general-purpose metals, including alloy and structural steels, as well as certain stainless steels (due to the cobalt content).
Easy Machine Operation: The cylindrical shank provides excellent clamping stability in drill chucks.
This set is an indispensable tool in professional workshops where reliability and durability are key.
