Twist Drill — Type N, 4.2 mm, 135° point angle, short, bright finished, HSS‑G, DIN 338

The Twist Drill Type N is a short HSS‑G metal drill designed for precision drilling in demanding materials with a 135° point angle and a fully ground shank for high concentricity.

• Short design for improved stability
• HSS‑G geometry for precise metalworking
• 135° point angle for hard material entry
• Fully ground shank for excellent concentricity
• Conforms to DIN 338 for short twist drills

Precision Material and Cutting Performance

The short HSS‑G construction of this twist drill combines sharp cutting edges with material hardness optimised for metalworking. A ground flute geometry results in clean holes and high roundness, while the shorter overhang reduces vibration and bending. For users working with alloyed and unalloyed steel, cast steel, spheroidal graphite iron, non‑ferrous metals and hard plastics, this design translates into higher drilling speed and reduced feed force compared with conventional HSS tools. HSS‑G (ground High Speed Steel) means edges are manufactured by CNC grinding for better sharpness and hole quality.

Designed for Demanding Metalwork

Engineered as a Type N (normal spiral) twist drill, the 135° point angle facilitates controlled entry into harder workpieces and reduces the tendency to wander on start. This geometry shortens initial penetration time and improves centring when commencing a bore. Because the tool is a short variant, it is particularly suitable for stationary and hand‑guided drilling where stability and accuracy are critical. The cutter is therefore recommended for precision shops and maintenance tasks that require consistently round, burr‑reduced holes.

Handling, Compatibility and Practical Advantages

With an Overall Length of 75 mm and a Spiral Length of 43 mm, the short profile ensures a stiff setup when mounted in drill chucks. The fully ground cylindrical shank aids in secure clamping and precise run‑out on collets or chucks used in Drilling Machines and hand drills. Users will find less chatter and improved surface finish, which reduces subsequent rework. For laypersons: a fully ground shank means the shaft and flute were machined to exact tolerances rather than rolled, giving better balance and a sharper cutting geometry.

Who Benefits Most from This Tool

This short twist drill is aimed at professionals and advanced hobbyists who bore metals requiring repeatable accuracy—toolmakers, maintenance technicians and fabrication shops. Because the drill suits harder materials, it is less ideal for very soft woods where specialised wood bits give cleaner guidance; however, its robustness makes it versatile for many workshop applications. If precise, repeatable metal holes are your priority, this product meets those needs through focused engineering rather than general‑purpose compromise.

FAQ

What is the primary use of the Twist Drill (MetavCUT Type N) and when should it be chosen?
The MetavCUT Twist Drill Type N is primarily used for machining high‑strength materials and larger drill diameters; its short design and ground flutes make it suitable for precision work in steel, cast alloys and hard plastics where stability and clean hole quality are required.

Which three drill types exist and how does the MetavCUT Twist Drill fit in?
The three common drill categories are metal drills, wood drills and stone/concrete drills. The MetavCUT Twist Drill Type N belongs to the metal drill family and is optimised for metalworking rather than for timber or masonry applications.
