Twist Drill (Drill Bit) – 7.5 mm, 135° tip, Type N, Bright Finished, Short, HSS‑G, DIN 338 by MetavCUT

The Twist Drill short Type N drill bit is a precision metalworking drill designed for Drilling Machines, offering a 7.5 mm diameter and a 135° tip angle for robust performance in hard materials.

• Short Type N design for high stability
• HSS‑G: up to 40% faster drilling and less feed force
• 7.5 mm diameter with 135° tip for hard steels
• Fully ground shank for precise clamping
• Conforms to DIN 338 for short metal Twist Drills

Faster metalworking through optimised HSS‑G performance

The HSS‑G material provides a measurable efficiency advantage: according to manufacturer data this fully ground High Speed Steel formulation enables up to 40% faster drilling and requires roughly 50% less feed force compared with conventional HSS bits. This translates into shorter cycle times and reduced operator effort when machining alloyed and unalloyed steels, cast steels, cast iron, sintered iron, tempered castings, non‑ferrous metals and hard plastics. The result is higher productivity in workshops and production environments without sacrificing hole quality.

Stability and precision thanks to the short DIN 338 format

A short Spiral Length and reduced overhang, as defined by DIN 338, reduce deflection and vibration during drilling. This geometry improves concentricity and hole tolerances on stationary and portable Drilling Machines, making the bit especially suitable where rigidity matters. For precision tasks in metal fabrication or maintenance work, the compact design minimises chatter and bending, delivering cleaner holes and extending tool life through lower mechanical stress.

Tip geometry and dimensions engineered for hard materials

The 7.5 mm diameter combined with a 135° tip angle is tailored for harder materials such as stainless steel and other tough alloys. A larger tip angle increases the material contact area at the start of the cut, reducing the tendency to grab and shortening the initial penetration time. The Type N normal spiral is the classical metalworking profile, optimised for chip evacuation and consistent cutting in metallic substrates. The bit is bright finished for good surface consistency and chip flow.

Secure clamping and simple regrinding for extended use

The fully ground cylindrical shank guarantees accurate seating in chucks and collets, supporting repeatable concentricity and uncomplicated tool changes. Compared with rolled shank variants, a ground shank improves grip and reduces slippage under higher torque. Additionally, the straightforward geometry of this Twist Drill allows economical regrinding where appropriate, helping to extend service life and keep workshop costs down while maintaining acceptable hole quality.

Practical applications and recommended user groups

Designed for robust metalworking tasks, this short Twist Drill suits maintenance technicians, toolroom operatives and industrial workshops that require reliable, repeatable holes in steel and related materials. Its balance of stability, tip geometry and HSS‑G performance makes it a practical choice for production runs on Drilling Machines as well as precise repair and retrofit jobs where reduced runout and clean entry are important. METAVCUT’s Basic Line positions this bit as a dependable everyday tool for demanding metal applications.

FAQ

What materials is the Twist Drill by MetavCUT suitable for and where is it best used?
The MetavCUT Twist Drill short Type N is intended primarily for metalworking; its HSS‑G composition and Type N spiral make it well suited to alloyed and unalloyed steels, cast steels, cast iron, sintered iron, tempered castings, non‑ferrous metals and hard plastics, and it performs reliably in workshop and industrial drilling applications.

How does the short design affect drilling results with the MetavCUT Twist Drill?
A short format per DIN 338 reduces the exposed length of the bit, increasing stiffness and lowering the risk of bending; this improves concentricity and hole accuracy on Drilling Machines and is particularly advantageous for precision tasks and drilling in hard materials.

For what are Twist Drills used?
Twist Drills are mainly applied when machining high‑strength materials and larger diameters; this form is easy to regrind and withstands higher loads, making it a common choice for demanding metalworking and production tasks.

Which three drill types are there?
The main categories are metal drill bits, wood drill bits and stone/concrete drill bits.
