Twist Drill – Short Type N, 3.5 mm, 135°, 5% Cobalt-Alloyed, HSS‑E, Fully Ground, DIN 338 (MetavCUT)

The Twist Drill is a short Type N drill designed for precise metalworking in hand drills and drilling machines.

• Short design for high stability and precision
• 3.5 mm diameter for fine, precise holes
• 135° tip for harder materials like stainless steel
• 5% cobalt-alloyed HSS‑E for increased wear resistance
• Fully ground flutes for clean, accurate holes

Engineered for precise metal drilling with reduced flex

This short Twist Drill is optimised for metal applications where dimensional accuracy matters. With a 3.5 mm diameter and a 135° point angle, it reduces walking on hard surfaces and shortens the pilot time when entering stainless steel or other tough alloys. The geometry follows DIN 338, which classifies short HSS drills with a cylindrical shank. As a result, users benefit from repeatable hole position and improved concentricity when working on both stationary and portable machines.

Short length and fully ground construction for stability

The reduced overall length and shorter overhang translate into less deflection and improved control during drilling. The 39 mm spiral length and 70 mm overall length keep the cutting forces close to the chuck, while the Fully Ground flute geometry ensures a sharp cutting edge and excellent roundness of the hole. This combination is particularly helpful for precision tasks and reduces the risk of chattering when drilling through thicker or harder sections of metal.

Material selection and wear resistance for demanding tasks

Manufactured from HSS‑E with 5% cobalt-alloyed composition, this short spiral drill offers enhanced red hardness and wear resistance compared with standard HSS. The cobalt addition supports higher cutting temperatures and extends tool life in continuous or interrupted cutting conditions. Being a Type N (normal spiral) geometry, it is primarily aimed at metalworking; the flute design facilitates reliable chip evacuation for cast iron, alloyed and unalloyed steel, and many non‑ferrous metals.

Practical recommendations for safe, accurate use

For best results clamp the workpiece securely, select appropriate spindle speeds and use coolant for stainless and other heat‑resistant alloys. The short design suits precise workshop tasks, maintenance and production runs where hole quality and repeatability are priorities. A short spiral drill is less suitable for deep, through‑holes beyond its flute capacity; for deeper holes consider a longer, purpose‑designed drill. MetavCUT's short design is ideal for users seeking controlled, clean holes with reduced breakage risk when used with adequate support and cooling.

FAQ

What materials is the Twist Drill by MetavCUT (Type N) suitable for?
The MetavCUT Twist Drill (Type N) is primarily intended for metalworking; its HSS‑E composition with 5% cobalt‑alloying makes it suitable for alloyed and unalloyed steel, cast iron and many non‑ferrous metals. For stainless steel or other heat‑resistant materials use cutting fluid and moderate speed to preserve tool life.

Which three drill types exist?
Common categories are metal drills, wood drills and stone/concrete drills. The MetavCUT Twist Drill belongs to the metal drill group and is optimised for metal applications rather than woodworking or masonry.
