Twist Drill 4 mm — Type N, Short, TIN-coated HSS-G, 135° (DIN 338) by MetavCUT

The Twist Drill 4 mm is a short Type N drill designed for precise metal drilling with a Drilling Machine, combining a TIN-coated finish and HSS-G material for enhanced life and performance.

• Short design for improved stability and precision
• TIN-coated surface for reduced friction and wear
• Fully ground shank for high concentricity and clean holes
• 135° point angle for tougher materials and stainless steel
• Conforms to DIN 338 for short HSS twist drills

Increased precision and longer tool life for metalworking

Engineered for demanding metal applications, this short Twist Drill from MetavCUT delivers reliable performance when working with alloyed and unalloyed steel, cast iron and non-ferrous metals. The HSS-G construction means the flute geometry is produced by grinding, resulting in very sharp cutting edges and superior concentricity. The TIN-coated surface reduces friction and wear during cutting, which extends service life especially under appropriate cooling. For users seeking cleaner holes with fewer burrs, the ground geometry offers a measurable benefit in repeatable accuracy.

Stability and faster feeds thanks to the short design

Because the overall length is reduced, the short execution offers higher rigidity and less tendency to bend under load, which allows for more aggressive feed rates and a reduction in wandering when starting a hole. The fully ground shank ensures excellent runout characteristics in standard chucks, improving hole quality. The 135° point angle is optimised for harder materials and stainless steels: it shortens initial penetration and reduces the risk of chipping at the tip. For workshop environments where precision and cycle-time matter, this configuration supports efficient and consistent production.

Practical use, compatibility and recommended handling

This Type N Twist Drill is intended primarily for metalworking on stationary or portable drilling machines and is particularly suitable when holes up to moderate depths are required. For best results, use suitable coolant to benefit from the TIN coating and to reduce heat-related wear. The short, ground design makes the bit easier to regrind compared with rolled geometries, but care should be taken to avoid excessive force; the combination of sharpness and some brittleness makes controlled feeds advisable. Users seeking guidance on selecting the correct bit for specific alloys or machine setups can rely on METAV Werkzeuge’s expert consultation.

FAQ

What is the Twist Drill 4 mm used for and which materials suit it best?
The MetavCUT Twist Drill 4 mm (Type N) is primarily used for metalworking; it is applied to alloyed and unalloyed steel, temper castings, cast iron, sintered iron, brass, copper, bronze and hard plastics. Short, ground geometry and TIN coating make it robust for high-strength materials and larger diameters where durability is essential.

Which three drill types exist and how does the MetavCUT Twist Drill fit in?
Besides the MetavCUT Twist Drill (Type N) tailored for metal, the three main drill categories are: metal drills, wood drills and stone/concrete drills. The MetavCUT product belongs to the metal drill category, optimised for metalworking tasks rather than timber or masonry applications.
