Twist Drill — Short HSS‑E Type N Drill, 12.1 mm, 135° Tip, 5% Cobalt‑Alloyed, DIN 338, Fully Ground Shank

The Twist Drill is a short HSS‑E Type N drill designed for precise metal drilling with a 12.1 mm diameter and a 135° tip for hard materials.

• Short Design for greater Stability and Precision
• 12.1 mm Diameter optimized for Metalwork
• 135° Tip suited for Hard Materials like Stainless
• HSS‑E with 5% Cobalt for improved Heat Resistance
• Fully Ground Shank for excellent Runout Accuracy

Outstanding material performance for demanding metalwork

Made from HSS‑E with 5% cobalt, this short twist drill delivers improved Heat Resistance and wear performance compared with standard HSS. The cobalt alloy increases hot hardness so the cutting edge retains strength at higher temperatures, which benefits longer tool life under continuous drilling or when coolant is limited. As a result, users experience fewer regrinds and more consistent hole quality during production tasks.

Short geometry for maximum precision and stability

The reduced overall length and shorter overhang provide notably higher rigidity and less deflection than long drills, so vibrations are minimised and hole positions stay accurate. The Fully Ground flute geometry ensures sharp cutting lips and high concentricity, producing clean, burr‑reduced holes in metal. This design is especially beneficial for operations where precise hole tolerances and repeatability matter.

Optimised geometry for hard materials and versatile use

Equipped with a 135° Tip, the bit penetrates hard and tough steels with less walking at the start and an improved centring behaviour, making it suitable for stainless steel and other high‑strength alloys. The short flute length (101 mm Spiral Length) and total length of 151 mm support both stationary drilling machines and handheld Drilling Machines for repair, maintenance and workshop production. The Type N normal spiral is the classic choice for metalworking.

Built to DIN 338 and engineered for professional workflows

Manufactured to DIN 338, this short twist drill conforms to standardised dimensions and tolerances for short Cylindrical Shank HSS drills. The ground variant offers very sharp edges and consistent runout, while requiring careful handling and appropriate coolant to reduce brittleness. For best results, use with suitable lubricants and steady feed to maximise tool life and hole surface finish.

FAQ

What is the Twist Drill used for and which materials suit it best?
The MetavCUT Twist Drill (Type N) is designed primarily for metalworking; it is especially suited to drilling alloyed and unalloyed steel, cast iron, non‑ferrous metals and many plastics. Its short design and HSS‑E composition make it effective for precise holes in harder materials.

Which three drill types should be known for different materials?
When selecting tools, consider the three main groups: Metal drills (such as HSS or HSS‑E twist drills), Wood drills, and Stone/Concrete drills. The MetavCUT Twist Drill falls into the metal drill category.

What advantages does the short MetavCUT Twist Drill offer for production work?
A short design reduces overhang and increases rigidity, which improves positional accuracy and reduces chatter during serial drilling operations. Combined with the 5% cobalt alloy, the tool maintains cutting performance under higher thermal stress.

Why is DIN 338 important for this short twist drill?
DIN 338 standardises dimensions and tolerances for short cylindrical‑shank twist drills, ensuring interchangeability and predictable performance. The MetavCUT Twist Drill produced to DIN 338 provides consistent fit, runout and geometry for reliable workshop use.
