Twist Drill Type N — 12.5 mm, 135°, HSS‑G, Short, Bright finished, DIN 338, Fully Ground Shank

A Twist Drill Type N for precise metal drilling, engineered for stable performance in Drilling Machines and stationary workshop setups.

• Short design for higher stability and precision
• HSS‑G CNC ground cutting edges for cleaner holes
• 135° tip optimized for hard materials like stainless steel
• Fully ground shank for minimal runout and accurate centering

Faster, more efficient metal machining thanks to short design and HSS‑G

The short Twist Drill by MetavCUT combines a reduced overhang with HSS‑G CNC grinding to deliver measurable productivity gains: up to 40% faster drilling and roughly 50% less feed force compared with conventional HSS bits. This results in less operator effort and more consistent cycle times when working with alloyed and unalloyed steel, cast materials or hard plastics. Conformance to DIN 338 ensures that geometry and dimensions meet recognised workshop standards, which supports reproducible machining results in production environments.

Greater accuracy and better surface quality through optimized geometry

A 135° tip reduces walking and shortens the initial penetration time on hard workpieces, helping to achieve centred starts even in difficult materials. The fully ground flute geometry produces sharp cutting edges and high roundness accuracy, resulting in cleaner drill holes and reduced burr formation. For users aiming at precision components, the combination of short length and ground flutes means less bending and improved positional accuracy when drilling on pillar or CNC drilling machines.

Built for professional workshops and demanding applications

This short Type N Twist Drill is intended primarily for professional shops and manufacturers who require reliable performance for metalworking. The tool is especially suitable for operations in steel, cast iron, sintered materials and non‑ferrous metals, as well as applications involving hard plastics. Its stability under load and predictable behaviour make it a practical choice for both one‑off jobs and series production where repeatability and tool life are essential.

Practical guidance: use, cooling and expected behaviour

For best results with the MetavCUT short Twist Drill, use appropriate cutting speeds and apply coolant when machining stainless or tempered steels to avoid premature wear. The shorter overhang reduces the tendency to chatter; however, the ground variant can be more brittle than rolled types and benefits from controlled feed and adequate cooling. The Type N normal spiral is the conventional metalworking geometry—simple to sharpen, versatile in feed rates and suitable for most drilling machines.

FAQ

What is the main use of the MetavCUT Twist Drill Type N?
The MetavCUT Twist Drill Type N is primarily used for drilling into high‑strength metals and larger hole diameters; its short design and ground geometry make it suitable for precise metalworking tasks and for materials where stable cutting behaviour is required.

Which three general drill types exist?
The three main drill categories are metal drill bits (like the MetavCUT Twist Drill), wood drill bits and masonry/concrete drill bits.

Why are Twist Drills tipped or re‑pointed?
The point modification reduces the cross‑edge at the tip of the Twist Drill by sharpening the central cutting geometry; this lowers friction, requires less feed force and improves centring of the drill in the workpiece.

Can the MetavCUT Twist Drill be used for drilling wood?
A metal Twist Drill can be used in wood, but the MetavCUT Twist Drill Type N will typically provide inferior guidance and a rougher finish compared with dedicated wood bits; it is easier to re‑sharpen and shows less self‑feeding behaviour.

For which drilling depths is the Twist Drill most commonly used?
Solid drilling with a Twist Drill is common for diameters up to about 20 mm and drilling depths up to approximately 100 mm; the short MetavCUT version is especially suited to stable, through‑hole work in this range.

Which is better: HSS or HSSE?
There is no universal superiority of HSSE over HSS; the decision depends on actual working conditions. Evaluate whether the operational benefits justify the higher cost before choosing HSSE instead of HSS.
