Twist Drill — Type N, short HSS‑G 12 mm, 135° tip, bright finished (DIN 338) by MetavCUT

The Twist Drill (Type N) is a short HSS‑G metal‑drilling bit designed for precise work in hard materials on a Drilling Machine.

• Short design for improved stability and precision
• Fully ground shank for high Runout accuracy
• 135° tip for better centring in hard metals
• Conforms to DIN 338 for standardized quality
• Bright finished surface for corrosion resistance and inspection

Precision and speed through engineered geometry

The HSS‑G construction and the short design deliver measurable advantages in metalworking. A shorter protruding length reduces bending and vibration, which directly improves hole quality and tool life. The fully ground flute geometry ensures sharp cutting edges and superior Runout Accuracy, while the specified 135° tip angle shortens plunge time in harder materials. For tasks that demand consistent hole geometry and minimal rework, this combination offers faster drilling with lower required feed force.

Reliable performance in demanding metal applications

Designed as a Type N normal spiral, the Twist Drill by MetavCUT is particularly suited to alloyed and unalloyed steels, cast steel, cast iron variants, sintered iron, and many non‑ferrous metals. The geometry supports effective chip evacuation during Through‑Drilling and contributes to clean, burr‑reduced holes. The 135° tip reduces the tendency to walk at start‑up and helps with centring when pre‑drilling is impractical, making it a solid choice for production or repair work on a Drilling Machine.

Handling, sharpening and recommended use

Because the flutes are produced by CNC grinding (HSS‑G), the bit achieves very sharp edges and high concentricity but can be more brittle than rolled alternatives; therefore, cutting fluids and appropriate speeds are recommended for stationary or guided drilling operations. The fully ground shank simplifies clamping and reduces slippage in the chuck. When reconditioning is needed, the ground geometry is easier to resharpen precisely, maintaining performance over multiple regrinds.
