Twist Drill — Twist Drill, Diameter 9 mm, 135° Tip, Extra Long, Bright Finished, HSS‑G, DIN 1869

The Twist Drill is an extra‑long HSS‑G drill bit for drilling machines, designed for deep metal drilling and precise holemaking in alloyed and unalloyed steels.

• Extra long design for deep drilling
• 9 mm diameter with 135° tip angle
• HSS‑G fully ground for precise bores
• Conforms to DIN 1869 for deep‑hole work

Precision and material: ground HSS for clean metal holes

The fully ground HSS‑G geometry delivers high concentricity and sharp cutting edges, producing clean, precise holes in metal. Grinding the flutes rather than rolling creates a sharper cutting profile, which reduces chatter and improves roundness when used with appropriate feed and coolant. This makes the bit particularly suitable for alloyed and unalloyed steel, cast iron and non‑ferrous metals where hole quality and dimensional accuracy are required.

Deep drilling capability: extra length for difficult access

With an extra long overall length and an extended spiral, this design allows drilling in deep parts or where access from the rear is restricted. The extended spiral assists chip evacuation during deeper cuts, reducing the risk of clogging. For tasks requiring long reach, the extra‑long execution provides the working length necessary without compromising guidance when used in a suitable drilling machine and with correct cooling.

Tip geometry and performance: 135° for harder materials

A 135° tip angle reduces the tendency to wander and shortens centring time on harder workpieces such as stainless steel. The larger tip angle reduces the aggressiveness of the lead, distributing cutting forces over a broader area and often requiring less feed force. For demanding materials, the combination of tip geometry and HSS‑G composition improves tool life when adequate coolant and a stable setup are used.

Practical use and user group: suited for workshops and industrial settings

This twist drill was developed for professional workshops and industrial users who need reliable deep drilling in metals. It is best applied in drilling machines under steady clamping and with cooling. Compared with rolled types, the ground version can be re‑sharpened more easily to renew cutting edges, making it advantageous for users who perform maintenance on tooling and value reproducibility and finish.

FAQ

What is the MetavCUT Twist Drill used for?
The MetavCUT Twist Drill is primarily applied for drilling high‑strength workpieces and larger diameters in metal; its extra‑long HSS‑G design and DIN 1869 specification make it suitable for deep drilling where extended reach and durable cutting performance are required.

Which three drill types exist?
Common categories are Metal drills, Wood drills and Masonry/Concrete drills; the MetavCUT Twist Drill belongs to the metal drill category and is optimised for metalworking tasks.

For what is a Twist Drill mainly used?
A Twist Drill is mainly used for machining high‑strength materials and larger hole diameters; its form allows straightforward resharpening and it withstands higher loads in demanding applications.

Why are twist drills pointed?
The point reduces the cross‑edge at the tip of the Twist Drill, significantly lowering friction and feed forces while improving centring in the workpiece; a pointed geometry therefore eases penetration and enhances accuracy.
