Twist Drill — 6.9 mm, 135° Point, Type N, Short, Bright Finished, HSS-G, DIN 338 (MetavCUT)

A Twist Drill Type N for Drilling Machines, designed to deliver stable, precise holes in hard metals and industrial applications.

• Short design for increased stability
• 6.9 mm diameter for precise holes
• 135° point angle for hard metals
• Fully ground shank for high runout accuracy
• Conforms to DIN 338 for consistent quality

Exceptional precision and faster machining for metalworking

The short-design Twist Drill from MetavCUT combines a reduced overhang with a HSS-G grinding geometry to minimise deflection and improve hole accuracy. This construction enables up to 40% faster drilling and requires about 50% less feed force compared with conventional HSS variants, which translates into shorter cycle times and less operator fatigue in repetitive tasks. The compact flute length and robust body deliver reliable concentricity when used in a properly clamped Drilling Machine, making this tool particularly effective for precision work in alloyed and unalloyed steels.

Ground geometry and point angle tailored for hard materials

A ground flute geometry (HSS-G) means the cutting edges and chip gullets are produced by CNC grinding, resulting in very sharp cutting lips and excellent surface finish of the hole. The 135° point angle reduces the tendency to wander on hard materials such as stainless steel, shortening the initial penetration time. Type N (Normal Spiral) geometry is optimised for metalworking, so the drill cuts efficiently while maintaining centring properties; for less experienced users, this design also makes resharpening straightforward while retaining cutting performance.

Best applications and handling recommendations for reliable results

Use this short HSS-G drill primarily for machining Metals on stationary or portable Drilling Machines where rigidity can be ensured. Suitable application ranges include Steel, Cast Iron, Sintered Iron, Non-Ferrous Metals and Hard Plastics. For deeper or larger-diameter holes, select appropriate pecking cycles or coolants to manage chip evacuation; this drill performs particularly well up to typical diameters and depths encountered in workshop settings when used with coolant and correct feeds. Operators benefit from reduced burr formation and cleaner hole edges when using the correct speed and feed for the material.

Durability considerations and safe working practice

While the ground construction offers superior precision and surface finish, it can be less tolerant to shock loads than rolled variants; therefore, avoid impact or hammer drilling modes and ensure stable clamping in the chuck. Regular cooling and proper feed rates extend tool life and prevent premature breakage. Conformity to DIN 338 assures standardised dimensions and interchangeability, supporting quality control and repeatability in production environments. For demanding or unfamiliar materials, consult technical support to confirm optimal cutting parameters.

FAQ

What is a Twist Drill used for?
The MetavCUT Twist Drill is primarily applied to the machining of high-strength materials and larger bore diameters; its short design and ground geometry make it especially suitable for precision drilling in metals such as alloyed and unalloyed steel. This variant is comparatively easy to resharpen and withstands higher loads while delivering clean, accurate holes.

Which three drill types exist?
There are three main drill families: Metal drills, Wood drills and Stone/Concrete drills. The MetavCUT Twist Drill belongs to the metal-drill category (Type N), optimised for drilling in metallic materials rather than soft wood or masonry.
