Twist Drill — Short HSS‑E Metal Drill, 12.5 mm, 135° Tip, Type N, 5% Cobalt‑Alloyed, Fully Ground Shank, DIN 338 (MetavCUT Standard Line)

A short Twist Drill designed for precision metal drilling with Drilling Machines and Hand Drills, especially where stability and clean holes in hard materials are required.

• Short Design: higher Stability and Precision
• 12.5 mm Diameter for robust Metal Holes
• 135° Tip Angle for Hard Materials like Stainless Steel
• 5% Cobalt-Alloyed HSS‑E for improved Heat Resistance
• Fully Ground Shank, DIN 338 Standard Compliance

Durable Material for demanding metalworking

Hardened HSS‑E combined with a 5% cobalt‑alloyed composition ensures that the drill retains hardness and resists softening at higher cutting temperatures. This material choice increases the tool life when working with alloyed and unalloyed Steel, Cast Iron and Nichteisenmetals. The metallurgical makeup reduces wear during continuous operation, so fewer tool changes are necessary and machining runs more economically.

Stable geometry for precise holes in tough materials

Thanks to the Short Design and a 12.5 mm Diameter, the tool shows reduced overhang and less tendency to deflect, which improves roundness and positional accuracy of holes. The 135° Tip Angle shortens initial penetration time and is tailored to harder materials such as Stainless Steel; combined with the Type N normal spiral this provides a reliable entry and controlled chip formation for clean bores.

Ground flutes and shank for concentricity and finishing quality

The version with a Fully Ground Shank (HSS‑G style) features CNC‑ground flutes that deliver sharp cutting edges and high runout accuracy. This results in smoother hole walls and improved surface finish compared with rolled drills. For production or assembly tasks where hole quality matters, this geometry reduces rework and supports consistent assembly fits.

Recommended use, handling and machine compatibility

Engineers and professional metalworkers will find this Twist Drill suitable for stationary and portable machines like conventional Drilling Machines and robust Hand Drills when appropriate clamping is used. For best results apply adequate cutting fluid and moderate feed to prevent premature breakage; coolant is especially advisable for deeper or continuous drilling in harder Steels. This short variant is particularly advantageous for precision operations and for drilling into thick or hardened components.

FAQ

What is the Twist Drill suitable for and which materials can it handle?
The MetavCUT Twist Drill (Type N) is primarily designed for Metal work; its HSS‑E composition and 5% cobalt‑alloyed formulation make it suitable for alloyed and unalloyed Steel, Cast Iron and many Non‑Ferrous Metals, offering improved heat resistance during demanding drilling tasks.

For what is a Twist Drill used?
A Twist Drill is mainly applied when machining high‑strength materials and for larger hole diameters. Its form is relatively easy to regrind and it withstands substantial loads. The shape and material make it especially suitable for metalworking operations.

Which three drill types exist?
The main types are: Metal drills (e.g. Twist Drill), Wood drills, and Stone/Concrete drills.

Why are Twist Drills point‑sharpened?
Point sharpening reduces the secondary cutting edge at the tip of the Twist Drill. By sharpening, frictional forces are significantly reduced, which lowers the required feed forces and improves centring of the drill tip in the workpiece.
