Twist Drill — Short Type N Drill, Ø 7.3 mm, HSS‑G, 135°, Bright Finished

The Twist Drill is a short Type N drilling tool designed for precise metalworking on drilling machines and hand drills.

• Short design for higher stability and accuracy
• HSS‑G ground geometry for sharp, clean holes
• 135° point angle optimised for hard materials
• Fully ground shank for excellent concentricity
• Conforms to DIN 338 for short twist drills

Higher stability for accurate metal holes

Shorter centre‑to‑end length gives the short design a clear advantage: it reduces overhang and vibration, resulting in greater stability and consistently round bores even at higher spindle speeds. This makes the tool particularly suitable for drilling steel and other hard materials where any bending of the tool would degrade hole quality. The reduced tendency to deflect means fewer reworks and a more predictable machining process for workshop and industrial operations.

Faster, cleaner drilling in tough materials

Thanks to the HSS‑G (ground high speed steel) geometry, chips form and evacuate cleanly while the cutting edges remain sharp. The 135° point angle is chosen to shorten the initial penetration time in hard metals and to improve centring on difficult surfaces. As a result, drilling becomes more efficient with less required feed force, which benefits both handheld and machine applications when working with alloyed and unalloyed steels, cast iron and other demanding materials.

Designed for professionals and workshop environments

Manufactured to the DIN 338 specification and offered in the Profi Line, this twist drill is engineered for repeatable performance in daily production. The fully ground shank ensures accurate clamping and minimal runout, supporting high precision on dedicated drilling machines. For craftsmen and maintenance technicians seeking a reliable short drill for metal, this Type N tool delivers the robustness and repeatability expected in professional settings.

Clear advantages for specific applications

When drilling in materials such as stainless steel or tempered castings, the combination of Type N normal spiral and a robust tip geometry reduces walking and improves guidance. The short version is preferable when hole precision supersedes reach, for example in jigged assemblies or where machine access limits tool length. Selecting this twist drill helps to avoid oversize holes and poor surface finishes that can arise from longer, more flexible cutters.

FAQ

What materials is the Twist Drill from MetavCUT suitable for?
The MetavCUT Twist Drill Type N is primarily designed for metal: alloyed and unalloyed steel, cast steel, cast iron, sintered iron, malleable iron, non‑ferrous metals and hard plastics. Its HSS‑G ground geometry delivers clean cutting action and good wear resistance for these materials.

Can the Twist Drill be used in a hand drill as well as a drilling machine?
Yes, the MetavCUT Twist Drill Type N can be used in both drilling machines and hand drills; however, its short design is especially advantageous in machine setups where stability and concentricity are critical for precision holes.

What is a Twist Drill used for?
A Twist Drill is mainly applied to machining high‑strength materials and larger drill diameters. The form is easy to grind and withstands greater loads, making it suitable for demanding metal drilling tasks.

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

Why are Twist Drills sharpened at the tip?
Sharpening reduces the cross‑edge at the tip of the Twist Drill, significantly lowering friction and required feed forces; it also improves centring of the tip in the workpiece.

Can a metal drill be used for wood drilling?
A metal drill can be used in wood, but guidance is poorer and hole finish is less clean. Metal drills are easier to resharpen and exhibit less self‑feed than dedicated wood drills.

For which drilling depths is the Twist Drill most commonly used?
A twist drill is typically used for through drilling; for diameters up to about 20 mm and drilling depths up to 100 mm it is the most frequently employed tool.

Is HSS or HSSE better?
The general belief that HSSE steels are always superior to HSS is incorrect. Choose between HSS and HSSE based on specific working conditions and whether the performance gain justifies the higher cost.
