Twist Drill — Type N Short, 6.1 mm, 135° tip, HSS‑G, Bright Finished (DIN 338)

The Twist Drill short Type N is a precision Drilling Machine bit designed for stable, fast metalworking, especially suited to hardened materials and demanding workshop applications.

• Short design for increased rigidity and accuracy
• Sharp 135° tip for harder materials
• HSS‑G ground for clean, concentric holes
• Fully ground shank for excellent runout accuracy
• Conforms to DIN 338 for short twist drills

Engineered for higher drilling performance in metalworking

This short Twist Drill from MetavCUT delivers a performance-oriented solution for metal fabrication: the HSS‑G material and optimized geometry enable faster material removal with reduced drilling forces. The ground flute geometry creates very sharp cutting edges that produce clean, precise holes and reduce burr formation. For craftsmen and production workshops, this means shorter cycle times and more reliable hole quality when processing legierte and unlegierte steels, cast steels and non‑ferrous metals.

Short length increases rigidity and improves accuracy

A reduced overall length significantly reduces the cantilevered section protruding from the chuck, which increases stability and lowers the risk of bending under load. This makes the short Type N Twist Drill particularly suitable for precise operations on a Drilling Machine and for drilling in hard materials where deflection would compromise hole accuracy. Operators will notice improved concentricity and less chatter compared with longer tools.

Ground HSS construction explained and practical benefits

The designation HSS‑G (ground High Speed Steel) denotes that the flute geometry is produced by CNC grinding rather than rolling. This results in extremely sharp cutting lips and high dimensional accuracy, which is advantageous for demanding metalworking. A potential drawback is higher brittleness compared with rolled variants, so use with appropriate coolant and in a stable clamping setup for best results. The 135° tip angle is chosen to reduce initial cutting forces and to suit harder materials such as stainless steel.

Where this tool is most effective and who benefits

Workshops, toolrooms and industry professionals who require repeatable, precise holes in metals will find the Twist Drill short Type N especially useful. The design targets applications up to typical diameters and depths encountered in component manufacture, repair and assembly. Its characteristics make it a rational choice for tasks requiring tight tolerances and reliable hole geometry rather than for soft‑wood or masonry applications.

FAQ

What materials is the MetavCUT Twist Drill short Type N suitable for?
The MetavCUT Twist Drill short Type N is intended primarily for metalworking and performs well in alloyed and unalloyed steel, cast steel, cast iron, sintered iron, malleable iron, non‑ferrous metals and hard plastics thanks to its HSS‑G construction and 135° tip.

Is coolant recommended when using the MetavCUT Twist Drill Type N?
Using coolant or cutting fluid with the MetavCUT Twist Drill short Type N is recommended for prolonged tool life and improved chip evacuation, especially when drilling harder materials and when aiming for the best surface finish and dimensional stability.

For what is a Twist Drill mainly used?
A Twist Drill is mainly applied to the machining of high‑strength materials and large hole diameters. Its form allows relatively easy re‑grinding and it endures higher loads, which makes it suitable for tasks requiring robustness and repeatable performance.

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

Why are Twist Drills re‑pointed?
Re‑pointing reduces the cross‑cut at the tip of a Twist Drill. By re‑sharpening the point, friction forces are significantly lowered, which reduces required feed forces and improves centring in the workpiece.

Can a metal drill be used to drill wood?
A metal drill can be used in wood, but the guidance is worse and the hole finish is less clean. Metal drills are easier to re‑sharpen and exhibit less self‑feeding in soft materials.

At which drilling depths is the Twist Drill most commonly used?
The Twist Drill is the most used tool for through drilling. For diameters up to around 20 mm and drilling depths up to 100 mm, the Twist Drill is commonly employed.

Is HSS or HSSE better?
The general belief that HSSE steels are universally superior to HSS is incorrect. When choosing between HSS and HSSE for a MetavCUT Twist Drill Type N, assess whether your working conditions justify the higher cost of HSSE for your specific application.
