Twist Drill Type N — 6.4 mm, 135°, short, 5% cobalt-alloyed, HSS‑E, DIN 338

The Twist Drill Type N is a short HSS‑E metal drill designed for precise work in Hand Drilling Machines and stationary setups.

• Short design for increased rigidity and accuracy
• 135° point angle for hard materials like stainless steel
• HSS‑E with 5% cobalt for improved heat resistance
• Fully ground shank for high concentricity and clean holes
• Compliant with DIN 338 for short twist drills

Greater Precision through a Short, Stable Design

The short configuration of this Twist Drill minimises overhang and produces higher stability during drilling, which directly benefits precision and reduces the risk of wandering. The fully ground Shank delivers excellent concentricity, resulting in cleaner, rounder holes in Metal. For operators seeking reproducible results on benches or in jigs, the reduced tendency to deflect means less rework and better fit for threaded components.

Suited to Hard Materials — Faster Penetration, Better Control

With a 135° Point Angle and the Type N Normal Spiral geometry, this short HSS‑E tool is optimised for demanding tasks in Steel, Cast Iron and other hard materials. The geometry shortens initial touch‑in time and helps maintain the centre when starting a hole. Compliance with DIN 338 indicates manufacture to accepted dimensions and tolerances for short twist drills, supporting consistent performance across batches and easy integration in production workflows.

Practical Guidance for Efficient Use

Use the Twist Drill in a suitable Drilling Machine with adequate clamping and coolant to extend tool life. The 5% cobalt-alloyed composition increases heat resistance, allowing for higher cutting temperatures and improved wear stability; nevertheless, coolant or lubricant is advised for continuous or deep drilling. The shorter overall length favours operations where stiffness and tool control are critical, such as drilling into thicker plates or working with tight positional tolerances.

Material and Handling Benefits from HSS‑E Chemistry

The HSS‑E grade combined with 5% cobalt yields a balance of hardness and toughness that performs well under thermal load. The Standard Line production and the fully ground flute geometry create sharp cutting edges and excellent runout characteristics. Operators should note that ground drills offer superior hole quality but can be more brittle than rolled alternatives; therefore, controlled feed rates and proper cooling will help prevent chipping and extend service intervals.

FAQ

What is the MetavCUT Twist Drill Type N used for?
The MetavCUT Twist Drill Type N is primarily used for drilling Metal and is suitable for demanding applications where a short, stiff tool is required. It is especially effective on harder materials thanks to the 135° point angle and HSS‑E chemistry, which together improve centring and heat resistance.

For what is a Twist Drill used?
A Twist Drill is mainly applied to the machining of high‑strength materials and larger bore diameters. Its form allows relatively simple resharpening and it withstands higher loads. This geometry is commonly used where durability and the ability to drill tough materials are required.

Which 3 drill types are there?
Common classifications are Metal drills, Wood drills, and Masonry/Concrete drills.

Why are Twist Drills point‑ground?
Point grinding reduces the cross‑cut at the tip of the Twist Drill, which lowers friction and consequently the required feed forces. In addition, a ground tip improves centring in the workpiece and leads to more accurate, controlled drilling.
