Twist Drill — Type N, 12.4 mm, 135°, Short, Bright Finished, HSS‑G, DIN 338 (MetavCUT)

The Twist Drill Type N short version is a precision metalworking tool designed for stable, high‑performance drilling of hard materials on a drilling machine.

• Short design for higher rigidity
• Optimised for hard metals like steel
• Fully ground HSS‑G for precise holes
• 135° tip reduces walking in stainless steel

High‑performance Material for Demanding Metalwork

HSS‑G (High Speed Steel, Ground) gives this short twist drill a sharp cutting geometry and high dimensional accuracy. The fully ground flute profile produces clean, burr‑reduced holes and supports up to 40% faster drilling speeds while requiring approximately 50% less feed force compared with conventional HSS types, making it particularly efficient in professional machining. Users benefit from consistent hole quality and reduced operator effort when machining alloyed and unalloyed steels.

Short Geometry for Precision and Stability

The reduced overall length and shorter protruding part result in markedly improved stability and lower tendency to deflect. That geometry is especially advantageous when working on rigid setups, where vibration and runout must be minimised. Classified under DIN 338 as a short twist drill with a cylindrical shank, this version suits stationary or machine‑based applications and delivers repeatable concentricity in series production.

Built for Metals: Applications and Who Benefits

Engineered as a metal drill, this Type N tool from MetavCUT excels in drilling steel, cast steel, cast iron, sintered iron, non‑ferrous metals and hard plastics. The 135° tip shortens centre‑starting time and improves performance in stainless and harder alloys, making the tool suitable for workshops, maintenance teams and precision engineering shops that demand fast, accurate through‑holes in tough materials.

Operation, Maintenance and Safe Use

To achieve longest service life, use moderate feed with adequate coolant and avoid excessive flexing; fully ground drills can be more brittle and are best used in stable chucks or collets. Re‑grinding is possible and straightforward on ground geometries, but care must be taken to preserve the point angle and lip clearance. The fully ground shank ensures reliable clamping in the chuck and consistent concentricity during operation.

FAQ

What is the MetavCUT Twist Drill Type N mainly used for?
The MetavCUT Twist Drill Type N is mainly applied to the machining of high‑strength materials and larger drill diameters; its geometry is easy to regrind and it withstands higher mechanical loads, which supports demanding metalworking tasks.

Which three drill types exist?
The three primary drill types are metal drills, wood drills and stone/concrete drills; the MetavCUT Twist Drill Type N belongs to the metal drill category and is optimised for ferrous and non‑ferrous metals.

Why is the Twist Drill pointed?
The point sharpening reduces the cross‑edge at the tip of the drill; by sharpening the tip the friction forces are significantly lowered, requiring less feed force and improving centre accuracy when the MetavCUT Twist Drill Type N enters the workpiece.

Can the MetavCUT Twist Drill be used to drill wood?
A metal drill such as the MetavCUT Twist Drill Type N can be used in wood, but guidance and finish are inferior compared to dedicated wood drills; advantageously it is easier to resharpen and shows less aggressive self‑feeding behaviour.

At which drilling depths is the Twist Drill most commonly used?
A through‑hole is typically executed with a Twist Drill; for diameters up to about 20 mm and drill depths up to 100 mm this tool is the most frequently used option in metalworking.

What is better, HSS or HSSE?
The common assumption that HSSE steels are universally superior to standard HSS is incorrect; evaluate working conditions carefully to determine whether the higher investment for HSSE justifies the performance benefit for the intended MetavCUT Twist Drill Type N application.
