Twist Drill Type N — short, Ø 4 mm, 135° tip angle, 5% cobalt-alloyed, HSS‑E, DIN 338, fully ground shank — MetavCUT

The Twist Drill Type N is a short HSS‑E metalworking drill designed for Drilling Machines, offering improved stability and precise performance when machining hard and alloyed steels.

• Short design for increased stability
• 135° tip angle for harder materials
• 5% cobalt-alloyed for heat resistance
• Fully ground shank for high concentricity
• Conforms to DIN 338 for standardised dimensions

Stable, precise drilling even in hard materials

A short Twist Drill made of HSS‑E combines rigidity and wear resistance to reduce vibration and improve hole quality. The reduced overhang of the short execution limits bending and delivers consistent concentricity, which means cleaner holes and longer tool life when working with alloyed and unalloyed steel. The 135° tip angle is tuned to penetrate harder materials with less walking at the start, improving process reliability in demanding metalworking jobs.

Material and geometry that add real value

The use of 5% cobalt‑alloyed HSS‑E gives this drill enhanced red hardness and thermal stability, reducing wear at elevated cutting temperatures. A fully ground shaft and flute geometry ensure sharp cutting edges and excellent runout accuracy, which benefits precision assemblies and reaming-sensitive operations. For users who need tools that are easy to resharpen and that maintain edge geometry under load, this construction is a practical choice.

Designed to match industrial standards and applications

Manufactured to DIN 338, this short Twist Drill Type N is suited for standard metalworking set-ups on portable and stationary drilling equipment. The Type N spiral is the conventional choice for metal drilling, delivering controlled chip removal and a balance between cutting speed and surface finish. Typical applications include drilling in steel, cast iron, non-ferrous metals and many engineering plastics where a robust, general-purpose metal drill is required.

Practical notes for users and support

For drilling below 6 mm diameter, the short form factor reduces breakage risk and is especially useful when machining with minimal clamping or on smaller workpieces.

FAQ

For what is a Twist Drill used?
A Twist Drill Type N from MetavCUT is primarily applied when machining high‑strength materials and larger drill diameters; its geometry is easy to resharpen and it withstands higher loads, making it suitable for demanding metal drilling tasks and for materials where increased toughness and heat resistance are required.

Which three drill types exist?
Common categories are Metal drill (such as the MetavCUT Twist Drill Type N), Wood drill, and Masonry/Concrete drill; each group is optimised in geometry and material to perform best in its respective material class.
