Twist Drill (Drill Bit) – 11.5 mm, 135° tip, Extra-Long, Bright Finished, Fully Ground, HSS-G, DIN 1869

The Twist Drill (Drill Bit) is an extra-long HSS-G cutting tool for Drilling Machine applications, engineered for deep, precise holes in hard metals.

• Extra-long design for deep drilling
• 11.5 mm diameter for medium holes
• 135° tip geometry for hard materials
• Fully ground HSS-G for precise runout
• Conforms to DIN 1869 for deep-hole work

Deep-hole performance for demanding metalwork

The Extra-Long design of this Twist Drill delivers significant reach with a Spiral Length of 195 mm and a Overall Length of 280 mm, allowing deep-hole machining where standard lengths fall short. The 11.5 mm diameter provides a balance between stability and material removal rate, making the drill particularly suitable for through-holes and blind holes in tougher materials. For professionals facing restricted access or long reach requirements, this geometry reduces the need for extensions or special setups and helps maintain concentricity over long distances.

Precision geometry that improves hole quality

Manufactured as a Fully Ground HSS-G tool, the Twist Drill features ground flutes and cutting edges achieved by CNC grinding rather than forming. This results in very sharp cutting lips, high runout accuracy, and clean, burr-minimised holes in metal. The ground geometry typically enables up to 40% faster drilling and requires 50% less feed force compared with conventional rolled HSS types, which translates into less operator effort and steadier machining in stationary or machine-mounted operations.

Optimised tip angle and material compatibility

With a 135° tip angle, this Twist Drill is tuned for harder materials and reduces initial chattering and wandering at the start of a bore. The tool is suitable for alloyed and unalloyed steels, cast iron, sintered iron, non-ferrous metals and hard plastics; it can handle steels up to roughly 1000 N/mm² under appropriate cutting conditions. The larger tip angle shortens the effective lead-in time and supports better centring on tough surfaces, which is critical when consistent hole position and diameter tolerance are required.

Practical handling, cooling and machining notes

Because the Twist Drill is a ground HSS tool, it achieves high dimensional precision but can be more brittle than rolled designs; therefore machine mounting and the use of coolant are recommended for heavy-duty or interrupted cuts. Use moderate cutting speeds and consistent feed to exploit the HSS-G benefits and extend tool life. For drilling in very hard or abrasive materials, consider pecking cycles or intermittent withdrawal to clear chips effectively and avoid built-up edge formation.

Who benefits from this tool and when to choose it

This Twist Drill is aimed at workshop professionals, toolmakers and maintenance technicians who require reliable deep-hole drilling with minimal setup complexity. Its combination of DIN 1869 conformity, robust HSS-G material and long reach makes it well suited for demanding production, repair and prototyping tasks where precision and access are decisive factors.

FAQ

What is the Twist Drill by MetavCUT used for?
The MetavCUT Twist Drill (Drill Bit) is mainly applied to machining high-strength materials and larger hole diameters; its design is easy to regrind and endures higher loads, making it ideal where deep or demanding metal drilling is required.

Which three drill types exist?
Commonly recognised drill types are: metal drills, wood drills and stone/concrete drills; the MetavCUT Twist Drill belongs to the metal drill category and is optimised for such applications.

Why are Twist Drills tip-splitted (reground/pointed)?
The point modification reduces the cross-cut at the tip of a Twist Drill, cutting friction and therefore lowering the required feed forces while improving centring of the tip in the workpiece.

Can a metal Twist Drill be used to drill wood?
A metal Twist Drill like the MetavCUT Twist Drill can be used in wood, but guidance is less precise and hole finish typically is inferior; the metal drill is easier to resharpen and shows less self-feeding compared with dedicated wood bits.
