Twist Drill Type N — Short HSS-G, 5.5 mm, 135° Tip, Bright Finished

The Twist Drill Type N is a short, fully ground metalworking drill designed for precision drilling in hardened materials and use with a Drilling Machine.

• Short design for enhanced rigidity and precision
• 135° tip for demanding and hardened materials
• HSS‑G fully ground for sharpness and clean holes
• Conforms to DIN 338 for standardised quality
• Suitable for Drilling Machine and metal applications

Precision and Material Quality for Clean Metal Holes

The short Twist Drill from MetavCUT is manufactured from HSS‑G, providing exceptionally sharp cutting edges thanks to CNC grinding. This fully ground shank geometry yields high roundness accuracy and produces clean, burr‑reduced holes in metal. Because the flute geometry is ground rather than rolled, users gain improved concentricity and hole quality, which is especially important when subsequent machining steps or press‑fits demand consistent tolerances.

Stability and Performance for Tough Materials

A reduced overall length and shorter protrusion from the chuck significantly increase stiffness and reduce deflection, making this short Twist Drill ideal for precise work in harder materials. The 135° tip is optimised for stainless steels and other tough alloys, shortening the initial bore time and improving centring. According to manufacturer data, the ground HSS design can deliver up to 40% faster drilling while requiring about 50% less feed force compared with conventional HSS drills, which directly reduces operator effort and cycle time.

Application Focused: Metalworking and Machine Use

Designed primarily as a metal drill, this Twist Drill (Type N) suits a wide range of ferrous and non‑ferrous materials including alloyed and unalloyed steels, cast steels, cast irons, sintered irons, non‑ferrous metals and hard plastics. Its configuration targets stationary and portable Drilling Machines where high accuracy and repeatability matter. Operators seeking reliable performance for workshop production or repair tasks will find the short axial length advantageous for minimising runout and improving tool life under controlled cooling.

Handling, Limitations and Best Practices

Because ground HSS drills tend to be sharper and less ductile than rolled versions, they can exhibit greater brittleness under inappropriate use. It is recommended to use adequate cooling and support, avoid excessive overhang, and prefer machine setups that limit vibration. The DIN 338 classification confirms standard dimensions and tolerances for short cylindrical‑shank twist drills, simplifying tool selection and replacement across toolholders and machines.

FAQ

What is the MetavCUT Twist Drill Type N mainly used for?
The MetavCUT Twist Drill Type N is primarily used for machining high‑strength materials and larger drill diameters; its short design and ground geometry make it well suited to demanding metalworking tasks and produce precise, clean holes even in hard materials.

Can the MetavCUT Twist Drill Type N be used in a Drilling Machine for stainless steel?
Yes, the MetavCUT Twist Drill Type N with a 135° tip is especially intended for harder materials such as stainless steel, offering improved centring and reduced initial penetration time when used in a properly set up Drilling Machine.

What are Twist Drills used for?
Twist Drills are mainly applied to the machining of high‑strength materials and larger drill diameters; their geometry allows relatively easy regrinding and they withstand higher loads.

Which three main drill types exist?
The three primary drill types are Metal drills, Wood drills and Stone/Concrete drills.

Why are Twist Drills sharpened at the point?
Point sharpening reduces the cross‑edge at the tip of the Twist Drill, which substantially lowers friction and therefore requires less feed force; at the same time the sharpened tip centres the drill more reliably in the workpiece.

Can metal Twist Drills be used to drill wood?
Metal Twist Drills can be used in wood, but they typically provide poorer guidance and a less clean hole compared with dedicated wood drills; however, they are easier to resharpen and show less self‑feeding.
