Twist Drill (Type N) — MetavCUT short HSS‑E, Ø 7.9 mm, 135°, 5% cobalt‑alloyed, DIN 338, fully ground

A Twist Drill (Type N) designed for precision metalworking with a short, fully ground shank and a 135° tip angle for reliable centring in hard materials.

• Precision short design for stable drilling in metal
• 7.9 mm diameter for versatile metal applications
• 135° tip for improved centring in hard materials
• HSS‑E with 5% cobalt for superior wear resistance
• Fully ground shank for high runout accuracy

Durable material for demanding metalwork and longer tool life

The MetavCUT Twist Drill is made from HSS‑E with 5% cobalt‑alloyed composition, a combination that increases red hardness and wear resistance under elevated temperatures. This material choice improves tool life when machining alloyed and unalloyed steel, cast iron and non‑ferrous metals. The short design further reduces bending stress, so the drill sustains higher loads with less risk of breakage during demanding operations.

Stable geometry and tip angle for accurate holes

A 135° tip angle and classic fluting geometry ensure the drill centres reliably and reduces walking on hard surfaces such as stainless steel. The Type N normal spiral makes this tool suitable primarily for metalworking, providing a balance between chip evacuation and cutting edge strength. For operators this means cleaner entry holes, reduced rework and more predictable drilling performance in workshop environments.

Suited for professionals who prioritise precision and repeatability

Designed for use in a Drilling Machine or compatible hand drills, the short Twist Drill is ideal where stability and precision matter, such as jig work, production runs and machine shop tasks. Professionals benefit from the reduced overhang and higher rigidity: fewer deviations in hole geometry and improved repeatability when drilling series of components. The fully ground shank contributes to consistent clamping and low runout on collets and chucks.

Conforms to DIN 338 and built for easy handling and maintenance

Manufactured to DIN 338 for short twist drills with cylindrical shank, this tool follows recognised dimensions and tolerances, easing tool selection and replacement in professional settings. The fully ground flutes produce sharp cutting edges and excellent concentricity, while the short configuration simplifies cooling and reduces chatter. For best results use appropriate coolant and moderate speeds for the material to extend service life.
