Twist Drill Type N — 11 mm · 135° · Short · Bright finished · HSS-G · DIN 338

Twist Drill Type N by MetavCUT delivers a short, highly stable HSS‑G bit for precision metalworking on drilling machines and stationary equipment.

• MetavCUT Twist Drill Type N 11 mm, short design
• HSS-G ground bit for clean, precise holes
• 135° point angle for hard metals like stainless steel
• Short shank for higher stability and less deflection
• DIN 338 standardised for metalworking on machines

Faster cutting and lower feed force thanks to HSS‑G technology

The HSS‑G (ground high‑speed steel) construction of this short Twist Drill provides a tangible Work advantage: up to 40% faster drilling and approximately 50% less feed force compared with conventional HSS bits. This means shorter cycle times and reduced operator fatigue when machining Alloyed and Unalloyed Steel. Ground geometry produces sharp cutting edges and precise chip evacuation, making the bit particularly efficient for through‑holes in demanding metalwork.

Stable short design for precise drilling in tough materials

A reduced overhang and a short execution increase rigidity and minimise tool deflection, so holes remain round and on‑size even under higher cutting loads. The 135° point angle is optimised for hard materials such as Stainless Steel and Tempered Castings; the blunter tip shortens the penetration phase and improves centring on tough surfaces. For precision jobs where runout and wobble are critical, the short Type N configuration is the preferred choice.

Intended applications and recommended workpieces

The MetavCUT Twist Drill Type N is engineered primarily for metalworking: Alloyed Steel, Cast Steel, Gusseisen, Sintered Iron, Non‑Ferrous Metals and Hard Plastics. Use on stationary Drilling Machines or robust portable drilling equipment with appropriate clamping. For best results on thicker or denser workpieces, employ suitable coolant and moderate cutting speeds to preserve edge life and avoid excessive work hardening.

Ground vs rolled geometry, sharpening and handling tips

“Ground” indicates that the flute geometry and cutting lips are CNC‑sharpened rather than roll‑formed; the outcome is higher Rundlaufgenauigkeit and very clean bore surfaces, at the expense of somewhat increased brittleness. Reconditioning is possible by professional resharpening; however, typical practice is to use coolant and controlled feed to extend life. The Type N “normal spiral” geometry offers reliable chip removal in metal and is straightforward to resharpen for maintenance fleets.

FAQ

What is the MetavCUT Twist Drill Type N mainly used for?
The MetavCUT Twist Drill Type N is mainly applied for machining high‑strength workpieces and large hole diameters; its short, ground geometry is well suited to precise drilling in metals where clean bores and high dimensional accuracy are required.

Which three drill types exist?
Common drill categories are metal drills, wood drills, and masonry/concrete drills; the MetavCUT Twist Drill Type N belongs to the metal drill group and is optimised for metalworking tasks.

Why are Twist Drills pointed?
The point geometry reduces the cross‑cut at the tip; by sharpening the point the transverse edge becomes smaller, lowering friction and thus reducing required feed force while improving centring behaviour in the workpiece.

Can Twist Drills be used to drill wood?
A metal Twist Drill like the MetavCUT Type N can be used in wood, but guidance and finish are inferior to a dedicated wood bit; however, metal bits are easier to resharpen and show less self‑feeding behaviour.

For which drilling depths is the Twist Drill most commonly used?
Solid holes are typically executed with a Twist Drill; for diameters up to about 20 mm and drilling depths up to roughly 100 mm, the Twist Drill is the most frequently used tool.

What is better, HSS or HSSE?
The general belief that HSSE is always superior to HSS is incorrect; selection should be based on actual working conditions and whether the higher acquisition cost of HSSE is justified by the specific application.
