Spiralbohrer — Twist Drill (Diameter 9.7 mm, 135° Tip, Type N, 5% Cobalt-Alloyed, Short, Fully Ground, DIN 338, HSS-E) — MetavCUT

The Spiralbohrer Twist Drill is a short, fully ground metal-drilling tool designed for precise work in alloyed and unalloyed steels and other metals when used in a Drilling Machine

• Short design for increased stability and accuracy
• HSS-E with 5% cobalt for higher heat resistance
• 135° tip angle for improved centring in hard materials
• Fully ground flute geometry for precise, clean holes
• Conforms to DIN 338 for short twist drills

Precision and Strength for Hard Materials

The Twist Drill is made from HSS-E with 5% cobalt-alloyed composition, giving the tool improved heat resistance and edge stability when drilling metals. The 135° tip angle reduces walking on hard surfaces and supports cleaner hole entry, which is especially beneficial for stainless steel and other tough alloys. Type N (normal spiral) geometry means the flute helix and cutting angles are optimised for metalworking; this results in consistent chip evacuation and reliable cutting performance when used with appropriate Cutting Fluid.

Short Length for Better Stability and Accuracy

With a Diameter 9.7 mm, Spiral Length 87 mm and Overall Length 133 mm, the short execution minimises overhang from the chuck and therefore reduces deflection and vibration during drilling. Shorter projection increases rigidity, improving positional accuracy and lowering the risk of bend-induced runout. For fine or precision applications on metal components, the reduced cantilever effect helps achieve tighter tolerances and straighter bores.

Fully Ground Finish and Practical Advantages

The “geschliffen” or fully ground flute geometry produces sharp cutting edges and excellent concentricity. Compared with roll-formed alternatives, ground drills typically deliver finer surface finish and higher roundness in the hole, which is advantageous for assembly operations or when subsequent reaming/machining is planned. Users should note that ground drills can be more brittle than rolled variants and therefore benefit from controlled feed, correct spindle speeds and coolant during operation.

Recommended Uses and Handling Tips

Designed primarily for metalworking on stationary or portable machines, the Twist Drill excels in drilling alloyed and unalloyed steel, cast iron, non-ferrous metals and some plastics. For best results, clamp the work securely, select cutting speeds and feeds appropriate to HSS-E material, and apply coolant for heat-sensitive metals. The short Type N design makes this tool particularly suitable for precise maintenance, fabrication and production tasks where accuracy and durability are required.
