Twist Drill — Type N, 7.8 mm, 118°, HSS, short, black, DIN 338 (MetavCUT)

The Twist Drill from MetavCUT is a short Type N drill designed for precision metalworking in drilling machines and hand drills, offering a 7.8 mm diameter and a 118° point angle for reliable centring and stable performance.

• Short HSS design for improved stability
• Precise 7.8 mm diameter for accurate holes
• 118° point angle for better centring on workpieces
• Conforms to DIN 338 for short twist drills
• Suitable for drilling machines and hand drills

Robust HSS construction for durable metalworking

Built from HSS (High Speed Steel), this short Twist Drill combines toughness and elasticity for demanding metal applications. The roll-formed HSS manufacturing process reduces the risk of breakage when drilling smaller diameters and provides consistent performance in alloyed and unalloyed steel, cast iron, non-ferrous metals and many plastics. The compact geometry increases rigidity, which means fewer vibrations and cleaner hole quality when used in appropriate machines.

Short length and Type N spiral for precision and stability

A shorter overall length reduces overhang and thus the tendency to bend, delivering higher accuracy during machining. The short execution specified by DIN 338 makes the tool particularly suitable where stability and concentricity matter. The Type N normal spiral flute is optimised for metalwork, guiding chips away reliably while maintaining cutting edge life, and the 118° point angle supports easier centring on curved or less-than-flat surfaces.

Practical guidance on application and material compatibility

When the task involves drilling into steel, cast components or non-ferrous metals, the MetavCUT short Twist Drill is a practical choice thanks to its HSS composition and classical flute geometry. For softer materials a different point angle may be preferable, but for standard metalwork this configuration balances penetration and edge robustness. Regular checking of feed and speed settings in the drilling machine helps to maximise tool life and hole finish.

Who benefits and how to get optimal results

Workshop professionals and maintenance technicians who require repeatable, precise holes in metal benefit most from this short HSS Type N design. For best results, use appropriate cutting fluid when machining steels, ensure the drill chuck is concentric and avoid excessive feed that could overload the small-diameter flute. Proper resharpening of the 118° tip restores centring performance and lowers the required feed forces.

FAQ

What is a Twist Drill used for and where does the MetavCUT Type N excel?
The MetavCUT Twist Drill Type N is mainly applied to machining high-strength materials and larger bore diameters in metalworking; its short HSS design offers stability and easier handling under demanding loads, providing longevity and reliable performance for workshop and production use.

Which three drill types exist and how does this product fit in?
The three common drill categories are metal drills, wood drills and stone/concrete drills. The MetavCUT Twist Drill belongs to the metal drill category and is optimised for metalworking tasks with a Type N spiral and HSS material.

Why are Twist Drills pointed and what is the benefit of the 118° tip on the MetavCUT drill?
The point reduces the cross-edge at the tip of a Twist Drill; by pointing the tip the friction is significantly lowered, requiring less feed force and improving centring in the workpiece. The 118° geometry on the MetavCUT item balances penetration and centring for many common metals.

Can a metal Twist Drill be used to bore wood?
A metal drill such as the MetavCUT Twist Drill can be used in wood, but guidance and surface finish are inferior compared with dedicated wood drills. Metal drills are easier to resharpen and have lower self-feeding tendencies, yet they provide less precise tracking in soft timber.

For which drilling depths and diameters is the Twist Drill most commonly used?
A solid bore is typically made with a Twist Drill. For diameter ranges up to 20 mm and drilling depths up to 100 mm the Twist Drill is the most frequently used tool, making the MetavCUT short HSS drill suitable for many standard metalworking operations.

Is HSS or HSSE better for metal drilling?
The general belief that HSSE steels are always superior to HSS is not universally correct. Selection should consider actual working conditions and whether the higher acquisition cost of HSSE is justified; MetavCUT provides advice to choose the most appropriate grade for the intended application.
