Twist Drill — Type N, 4.8 mm, 135° tip, Short, 5% cobalt-alloyed, HSS‑E, DIN 338 (MetavCUT)

The Twist Drill Type N is a short configuration drill for precision metalworking, engineered for handheld drilling machines and demanding machining of harder materials.

• Short design for high drilling stability
• 4.8 mm Diameter for precise metal holes
• 135° Tip angle for harder materials
• 5% cobalt-alloyed HSS‑E for heat resistance

Longer life and heat resistance through alloyed HSS

Built from HSS‑E with a 5% cobalt alloy, this short Twist Drill offers improved hot hardness and wear resistance compared with standard high-speed steels. The cobalt enrichment helps maintain cutting edge integrity at elevated cutting temperatures, which is particularly beneficial when drilling stainless steel or other tough metals. As a result, users gain longer tool life and fewer tool changes during longer runs.

Stable short design for precise, vibration‑reduced drilling

The shortened overall length reduces cantilever and increases rigidity, making the tool less prone to bending and chatter. With a short configuration and fully ground flute geometry, this Twist Drill provides a precise cut and excellent concentricity even in handheld or portable setups. For workshop tasks that demand accurate hole placement, the reduced overhang translates directly into cleaner holes and improved repeatability.

Geometry optimised for harder materials and clean entry

A 135° tip angle is chosen to reduce wandering on hard surfaces and to lower the initial penetration force, which improves centring on stainless and alloyed steels. The ground geometry (HSS‑G style) yields sharp cutting lips and a defined chisel edge, producing clean bores with good surface quality. For operators who require predictable performance when starting a hole in steel, this geometry is a practical advantage.

Suited uses and target users

This Twist Drill in the Standard Line series is intended primarily for metalworkers, maintenance technicians and industrial workshops that perform drilling in alloyed and unalloyed steel, cast iron, non‑ferrous metals and selected plastics. The tool is a robust choice for general metal drilling tasks on portable drilling machines and small machine tools where stiffness and hole quality matter more than extreme reach.

Handling, sharpening and recommended operating practice

Because the flute geometry is fully ground, the drill produces fine chips and precise holes but can be more brittle than rolled types; therefore, the tool benefits from controlled feeds and adequate cooling. For best results use cutting fluid when drilling harder alloys and avoid excessive feed rates on small diameters. If regrinding is required, the ground geometry allows restoration of sharp cutting edges, but care must be taken to preserve the 135° tip form for consistent performance.

FAQ

What is the Twist Drill from MetavCUT mainly used for?
The MetavCUT Twist Drill is primarily used for drilling high‑strength materials and larger diameter metal holes; its short design and ground geometry make it suitable for precision work in alloyed and unalloyed steel, cast iron, non‑ferrous metals and plastics, while offering easier regrinding and good resistance to breakage on small diameters.

Which three drill types exist and how does the MetavCUT Twist Drill fit in?
Common categories are metal drills, wood drills and masonry/concrete drills; the MetavCUT Twist Drill belongs to the metal drill category and is optimised for metalworking tasks with features like HSS‑E material and a Type N spiral suited to machining metals.

Why are Twist Drills point‑sharpened?
Point sharpening reduces the cross‑cut at the tip, lowering friction and cutting forces; by sharpening the tip the MetavCUT Twist Drill requires less feed force, centres better in the workpiece and delivers improved drilling behaviour across a range of metals.

Can a metal Twist Drill be used to drill wood?
A metal Twist Drill can be used in wood, but the MetavCUT Twist Drill will generally give less precise guidance and a rougher finish than a dedicated wood bit; however it is easier to resharpen and offers lower self‑feeding tendency compared with some specialised wood drills.
