Twist Drill — Type N short HSS drill, 7.9 mm, 118°, black, DIN 338 (MetavCUT)

The Twist Drill Type N is a short HSS metal drill designed for precision drilling in steel and non-ferrous materials, compatible with standard Drilling Machines and handheld units.

• Short HSS design for increased stability
• 7.9 mm diameter with 118° tip for reliable centring
• Conforms to DIN 338 for short twist drills
• Type N Normal spiral optimised for metal drilling
• Black finish for clear visual contrast during machining

Long-lasting HSS construction for demanding metalwork

Deriving strength from High Speed Steel (HSS), this short twist drill combines elasticity and toughness to resist breakage when machining small diameters. The HSS composition makes the tool especially suitable for drilling in alloyed and unalloyed Steel, Cast Iron, Non-Ferrous Metals and various Plastics, while retaining the ability to be resharpened easily. This focus on material quality results in a tool that offers predictable wear behaviour and extended service life for repetitive metalworking tasks.

Improved precision thanks to short design and 118° tip

A shorter overall length reduces overhang and bending, delivering greater Stability and more accurate hole positioning during high-precision operations. The 118° tip angle favours fast penetration and improved centring on curved or softer surfaces, making it a practical choice when consistent hole geometry is required. Together, the short execution and the tip geometry minimise deviation and chatter, which increases first-pass accuracy in production or repair work.

Optimised for metal: Type N spiral and DIN 338 compliance

The Normal spiral of Type N is a classic geometry tailored to metal drilling: it balances efficient chip removal with robust cutting edges. Conformance to DIN 338 clarifies that this is a short twist drill with a cylinder shank manufactured to industry standards, ensuring interchangeability and reliable performance in both stationary and portable drilling equipment. For tasks involving drilled holes in metal components, this configuration offers a dependable combination of repeatability and tool life.

Practical compatibility and recommended uses

Designed for use in standard Drilling Machines and handheld devices, the drill’s 7.9 mm diameter and 117 mm total length make it well suited for through-holes and shallow-depth bore operations up to typical industrial limits. The short spiral length improves rigidity for tougher alloys and reduces wobble when drilling from the face of the workpiece. This makes the tool appropriate for maintenance, prototyping and small-batch production where precision and resilience are required.

Who benefits from this drill

Machinists, maintenance technicians and workshop professionals engaged in metal fabrication and repair will value the balance of Precision and durability offered by this short HSS twist drill. Its suitability for a range of steels and non-ferrous materials, together with easy resharpening, supports cost-effective tool management and predictable machining results even under frequent use.

FAQ

What is the Twist Drill (MetavCUT, Type N) best used for?
The MetavCUT Twist Drill Type N is primarily applied to the machining of high-strength materials and larger drill diameters in metalworking. Its design allows for straightforward resharpening and it withstands greater loads, making it suitable for alloyed and unalloyed Steel, Cast Iron, Non-Ferrous Metals and Plastics.

Which three drill types exist?
The main categories are Metal drills, Wood drills and Stone/Concrete drills; the MetavCUT Twist Drill Type N belongs to the metal drill group optimised for steel and related materials.

Why are Twist Drills pointed?
Pointing reduces the cross-cut at the tip of the Twist Drill, significantly lowering friction and thus requiring smaller feed forces. At the same time the sharpened tip improves centring in the workpiece for more accurate hole starts with the MetavCUT Type N.

Can the Twist Drill (MetavCUT, Type N) be used for wood drilling?
A metal drill such as the MetavCUT Twist Drill Type N can be used in wood, but guidance and finish are usually inferior compared with dedicated wood bits. Metal drills are easier to resharpen and tend to have less self-feed in wood.

For which drilling depths is a Twist Drill most commonly used?
A solid bore is typically performed with a Twist Drill. For diameters up to about 20 mm and drilling depths up to 100 mm a Twist Drill is the most frequently used tool, including the MetavCUT Type N configuration.

Is HSS or HSSE better?
The general assumption that HSSE steels are always superior to HSS is incorrect. Assess working conditions carefully to decide whether the higher purchase price of HSSE is justified; for many standard metal drilling tasks the MetavCUT HSS answer is appropriate.
