Twist Drill short Type N — Diameter 12.3 mm · 135° Tip · 5% Cobalt-Alloyed · HSS‑E · DIN 338 · Fully‑Ground

The Twist Drill short Type N is a precision HSS‑E metalworking drill designed for stable, high‑accuracy holes in hard materials on drilling machines and hand drills.

• Short Design for Higher Stability and Precision
• 5% Cobalt-Alloyed HSS‑E for Increased Wear Resistance
• 135° Tip Angle for Easier Entry into Hard Materials
• Fully-Ground Shank for High Runout Accuracy
• Conforms to DIN 338 for Standardised Quality

Maximum Precision through a Short, Stable Geometry

The short construction of this Twist Drill reduces the unsupported length outside the chuck, which significantly improves Stability and minimises deflection during drilling. This leads to more consistent hole diameter and better surface finish in demanding operations. For professional workshops and maintenance tasks, the reduced tendency to bend makes this design especially suitable when tight tolerances are required.

Durable Alloy and Tip Geometry for Hard Materials

Manufactured from HSS‑E with 5% Cobalt, the drill offers higher red hardness and wear resistance compared with standard HSS. The 135° Tip is optimised for hard and stainless steels: it reduces walking on the surface and shortens the time to penetrate the workpiece. HSS‑E (High‑Speed Steel with Cobalt) means the material retains hardness at higher temperatures, which improves tool life under continuous cutting and when coolant access is limited.

Ground Flutes and Type N Spiral for Accurate Metal Drilling

A fully‑ground shaft and sharpened flute geometry produce sharp cutting edges and excellent runout characteristics. Type N refers to a normal spiral suitable for metal drilling; the ground manufacturing process yields high concentricity and clean hole walls, while the short flute length promotes rigidity. For everyday metalworking—cast iron, alloyed and unalloyed steel, non‑ferrous metals and many plastics—this geometry balances cutting performance and service life.

Practical Guidance and Best Use Cases

Because of its short form and alloy composition, this drill performs best with steady clamping and, where possible, cutting fluid to carry away heat and chips. It is intended for use on drilling machines and compatible hand drills when rigidity is ensured. For diameters under 6 mm, the short, rolled or ground HSS design reduces breakage risk; for larger diameters the cobalt content and tip geometry help maintain penetration and tool life.

Who Benefits Most from This Tool

Workshop professionals, maintenance technicians and metal fabricators will appreciate the combination of Precision, Durability and conformity to DIN 338. The tool is designed to deliver repeatable results in production and repair contexts where accurate, burr‑reduced holes are required. The Standard Line series offers an industrial‑grade solution for repetitive metal drilling tasks.

FAQ

What is the Twist Drill used for and which materials suit it best?
The MetavCUT Twist Drill Type N short is primarily used for metalworking; it excels in drilling alloyed and unalloyed steel, cast iron, non‑ferrous metals and many plastics due to its HSS‑E composition and 135° tip, which together provide better penetration and wear resistance in hard materials.

Which three drill types are commonly distinguished?
The main categories are: Metal drills (for steel and alloys), Wood drills (timber‑specific geometry) and Stone/Concrete drills (for masonry and concrete).

For what is a Twist Drill typically used?
A Twist Drill is mainly applied in the machining of high‑strength materials and for larger hole diameters; its shape is easy to sharpen and withstands greater loads, making it suitable for demanding metal drilling tasks.

Why are Twist Drills sharpened (repointed)?
Sharpening reduces the cross‑edge at the tip, lowering friction forces and thus the required feed force; it also improves centring of the tip in the workpiece and yields cleaner, more accurate holes.
