Twist Drill Type N – 12.1 mm, 135° Point, Short, Bright Finished, HSS‑G, DIN 338

The Twist Drill Type N is a short HSS‑G metalworking drill designed for use with a Drilling Machine, offering high stability and precise holes in hard materials.

• Short design for higher stability and precision
• 135° point angle for hard materials like stainless steel
• HSS‑G ground geometry for faster, cleaner drilling
• Fully ground shank for excellent concentricity
• Conforms to DIN 338 for short twist drills

Short Design for Greater Stability and Precise Results

The Short execution reduces overhang and significantly increases Stability during drilling, which means less deflection and more accurate hole positioning. Shorter overall length leads to improved machine‑drill interaction on both stationary and portable Drilling Machines, so operators can achieve consistent results even when working with hard or alloyed steels. This construction particularly benefits setups where rigidity and repeatability are essential.

Ground HSS Geometry for Efficient Metalworking

The HSS‑G (ground High Speed Steel) flute geometry produces very sharp cutting edges and high Roundness Accuracy, delivering clean, burr‑reduced holes in metals. Compared with rolled designs, the ground finish allows for up to 40% faster drilling and requires significantly lower axial force, which improves cycle times and reduces operator fatigue in repetitive metalworking tasks. Note that ground drills are best used with adequate cooling and steady fixturing.

Engineered Tip and Application Range for Tough Materials

With a 135° Point Angle, this drill enters the workpiece with reduced tendency to wander and a flatter chisel edge, optimising performance in hard materials such as stainless steel, cast iron and sintered components. Classified as Type N (normal spiral), the geometry is the classic solution for metal drilling and performs reliably across a wide range of ferrous and non‑ferrous alloys. The design also supports straightforward resharpening when needed.

Who Benefits from This Tool

Production workshops, toolrooms and maintenance departments that require repeatable, precise holes in demanding materials will find the short Twist Drill especially suitable. The combination of a short shank, ground flutes and a robust tip angle makes it a solid choice for applications where deflection must be minimised and hole quality is critical. For manual drilling operations as well as machine setups, this drill delivers measurable efficiency improvements.

FAQ

What is a Twist Drill used for and which materials suit the MetavCUT Twist Drill Type N?
The MetavCUT Twist Drill Type N is primarily used for drilling metal; its short, ground HSS design is particularly suited to alloyed and unalloyed steel, cast steel, cast iron, sintered iron, non‑ferrous metals and hard plastics, offering precise hole quality and reliable performance on Drilling Machines.

For what is a Twist Drill mainly used?
A Twist Drill is mainly applied when machining high‑strength materials and larger hole diameters; its form allows easy resharpening and it withstands greater mechanical loads, making it appropriate for demanding metalworking tasks.

Which three drill types exist?
The main drill types are metal drills, wood drills and masonry/concrete drills.

Why are twist drills sharpened at the tip?
Tip sharpening reduces the cross‑edge at the drill point, lowering friction and thus requiring less feed force while improving centring accuracy in the workpiece.

Can a metal twist drill be used in wood?
A metal (HSS) twist drill can be used in wood, but guidance and finish are generally inferior compared with dedicated wood drills; however, HSS drills are easier to resharpen and exhibit less self‑feed.

At which drilling depths is the twist drill most commonly used?
Twist drills are the standard tool for through drilling; they are most commonly used for diameters up to 20 mm and depths up to 100 mm, providing efficient material removal for solid drilling.

Is HSS or HSSE better?
The general belief that HSSE steels are categorically superior to standard HSS is incorrect; selection should consider actual working conditions to determine whether the higher cost of HSSE is justified.
