Twist Drill — MetavCUT Type N short HSS‑E, 7.8 mm, 135°, 5% cobalt‑alloyed, fully ground shank, DIN 338

The Twist Drill Type N short is a precision metalworking drill for drilling machines, designed for stable, accurate holes in hard and alloyed steels.

• Short design for higher stability and reduced deflection
• 135° point angle for hardened and stainless steels
• 5% cobalt‑alloyed HSS‑E for improved wear resistance
• Fully ground shank for high concentricity and precise running
• Conforms to DIN 338 for short cylindrical‑shank twist drills

Durable HSS‑E construction for demanding metalwork

Built from HSS‑E with 5% cobalt, this short twist drill offers increased Heat Resistance and superior wear behaviour when cutting alloyed and unalloyed steels. The cobalt‑enrichment improves toughness at elevated cutting temperatures, so the tool maintains its cutting geometry longer during repetitive metal drilling. This results in fewer tool changes and greater process reliability without sacrificing hole quality.

Stable short length for precision drilling

A reduced overall length and a shorter Spiral Length give the drill a stiffer setup and less tendency to bend under load. That improved rigidity makes the short Twist Drill especially suitable for precision work and for drilling into hard materials where accuracy is essential. For shop applications on drilling machines or hand drilling machines, the compact geometry contributes directly to cleaner holes and better positional accuracy.

Geometry optimised for hard materials

The 135° point angle reduces walking on the surface and shortens the plunge time when starting holes in tougher materials such as stainless steel. Combined with the Type N normal spiral geometry, this results in reliable chip evacuation and consistent cutting action when working with metal. For users less familiar with drill geometry: a larger point angle leads to a flatter tip that resists wear and improves centering on hard surfaces.

Precision shank and production standard

The fully ground cylindrical shank (HSS‑G style) ensures excellent concentricity in chucks and collets, reducing runout and vibration. Manufactured to DIN 338, this short twist drill follows industry standards for dimensions and tolerances, making it easy to integrate into existing tooling setups. The careful grinding process yields sharp cutting edges and a clean drill profile, which is beneficial for fine metalworking and repeatable results.

Practical guidance for use and care

When using this short Twist Drill in metal, apply adequate cutting fluid and moderate feed to exploit the HSS‑E properties and avoid overheating. Short drills tolerate higher feeds thanks to their stiffness, but cooling remains crucial to extend life. For repairs or modifications, remember that fully ground drills can be re‑sharpened to restore cutting edges, though sharpening requires suitable tooling and skill to preserve geometry.
