Twist Drill (Type N) — 7 mm, 135° Point Angle, Short, Bright finished, HSS-G, DIN 338

A Twist Drill (Type N) designed for precise metal drilling in Drilling Machines, offering a short, stable geometry for work on hard materials.

• Short design for improved stability
• HSS-G material for high cutting performance
• 135° point angle for hard materials
• Fully ground shank for excellent runout accuracy

Durable HSS-G construction for faster, cleaner holes

The HSS-G material of this Twist Drill ensures high wear resistance and reliable cutting behaviour when machining Steel and other Alloys. Because the flute geometry is produced by CNC grinding, the tool achieves very sharp cutting edges and a high concentricity, which translates into cleaner holes and longer tool life under correct cutting conditions. Users will benefit from up to 40% faster drilling and about 50% less feed force compared with conventional HSS designs, provided adequate coolant and appropriate speeds are used.

Short overall length increases precision and reduces vibration

A shorter design reduces the exposed overhang and therefore minimizes bending and chatter during operation. This results in higher positional accuracy and makes the drill particularly suitable for precise work in hardened materials such as Stainless Steel. The designation to DIN 338 confirms the geometry and format as a short Twist Drill with a Cylindrical Shank, ensuring compatibility with common chucks and fixtures in metalworking shops.

Geometry optimised for metalworking and hard materials

The 135° point angle is tailored to reduce initial drilling forces and improve centring in tough materials, shortening pilot time and improving surface finish in the hole. As a Type N (normal spiral) drill, this tool is engineered primarily for Metal applications including Cast Iron, Sintered Iron, Tempered Castings, Non-Ferrous Metals and Hard Plastics. For best results, use on stationary or machine-mounted Drilling Machines and apply appropriate cooling to avoid tempering the cutting edge.

Target users and handling recommendations

Workshop professionals, toolroom technicians and demanding hobbyists will appreciate the combination of a short flute length and a fully ground shank that delivers consistent runout and repeatable hole quality. To avoid brittleness-related breakage, operate the Twist Drill with steady feed, adequate coolant and secure clamping. Ground drills can be re-sharpened more easily than rolled equivalents, maintaining edge quality and service life when reconditioned correctly.
