Twist Drill — Type N short, 3.5 mm, 135° point angle, TIN-coated, HSS‑G, DIN 338

The Twist Drill Type N short is a TIN‑coated HSS‑G metal drill designed for precise, stable drilling in hard materials with a 3.5 mm diameter and a 135° point angle.

• Short design for enhanced stability
• TIN-coated for extended tool life
• Fully ground shaft for high precision
• Optimised for hard metals such as steel
• Conforms to DIN 338 manufacturing standard

Engineered for precision and longer tool life

The short HSS‑G construction delivers high rigidity and precise hole quality even under tougher conditions. The TIN‑coating reduces friction and wear, which significantly extends the tool life when drilling metals. With a 3.5 mm diameter and a 135° point angle, the geometry is specifically suited to reduce walking on hard surfaces and to penetrate stainless and alloyed steels more effectively. This design helps achieve cleaner holes with less burr formation while maintaining long‑term performance.

Best use cases in workshop and industry

Choose this short Type N twist drill for demanding metalworking tasks on stationary drilling machines or robust hand drills where high stiffness and repeatable accuracy matter. The reduced overhang makes it ideal for short, deep plunge operations and for applications that require excellent concentricity. It is particularly recommended for alloyed and unalloyed steel, cast iron, copper, bronze and hard plastics where the combination of HSS‑G material and coating provides proven results.

Faster drilling with lower effort and improved runout

Thanks to the fully ground flute geometry, drilling can be up to 40% faster and require up to 50% less axial force compared with conventional untreated HSS tools in comparable conditions. The ground manufacture yields sharp cutting edges and excellent runout accuracy, which translates into superior surface finish and dimensional consistency. For workshop efficiency this means less rework and higher throughput on repetitive metal drilling tasks.

Practical handling, cooling and resharpening guidance

To maximise lifetime and safety, use appropriate coolant or cutting fluid; the TIN‑coating combined with cooling considerably reduces thermal load and wear. The 135° point angle shortens initial penetration time in harder materials, but the ground flute design can be more brittle than rolled variants—avoid excessive vibration and side loads. Re‑grinding is possible and practical: the tool geometry is straightforward to resharpen, restoring cutting edges and maintaining performance when required.

FAQ

What is the Twist Drill used for and which materials suit it best?
The Twist Drill from MetavCUT, Type N, is used primarily for machining high‑strength materials and larger drill diameters; its short design and high‑quality HSS‑G construction make it suitable for alloyed and unalloyed steel, temper castings, cast iron, sintered iron, copper, bronze and hard plastics. This form is easy to resharpen and withstands higher loads.

Which three drill types exist?
Commonly distinguished drill types are: Metal drill (such as the MetavCUT Twist Drill), Wood drill, and Stone/Concrete drill.

Why are twist drills resharpened?
The Tip is reshaped to reduce the cross cutting edge at the point. Resharpening lowers friction forces so that less axial feed is required and improves centring of the drill in the workpiece, which enhances performance and hole quality.

Can a Twist Drill be used to drill wood?
A metal Twist Drill from MetavCUT can be used in wood, but guidance and finish are inferior compared with dedicated wood drills. Metal drills are easier to resharpen and have lower self‑feeding tendencies, yet they deliver less clean, well‑guided holes in timber.
