Benefit from precise centring and chamfering in a single operation, combined with the wear resistance of HSS‑Co for reliable cycle times. The DIN 1835‑A cylindrical shank guarantees secure clamping and repeatability; order the item directly via Metav Werkzeuge or ask our consultants if further details are required.

NC centre drill D 5 mm HSS‑Co, 120° – TECWERK

The NC centre drill D 5 mm HSS‑Co is a spotting tool engineered for position‑accurate spot drilling and combined chamfering on NC machines and drill rigs

• Cobalt HSS construction for high wear resistance
• Cylindrical shank to DIN 1835‑A for secure clamping
• 120° point for accurate centring and chamfering
• Feed 0.04 mm/rev in steel up to 800 N

Reduce set‑up and improve tap starts with a single pass

The centre‑first design enables precise centring and initial chamfering in one operation, which reduces set‑up time and minimises the risk of drill walk before tapping. The 120° point geometry provides a defined entry and stable contact with the workpiece, resulting in consistently concentric start holes and better thread engagement. For mixed production runs the combined action of spot drilling and chamfering reduces fixture changes and improves overall process efficiency while maintaining high repeatability.

Long service life and secure toolholding for uninterrupted runs

Manufactured from HSS‑Co (cobalt high‑speed steel), the tool resists heat and wear better than conventional high‑speed steels, extending life under demanding conditions. The DIN 1835‑A cylindrical shank with tolerance h8 ensures a precise fit in standard toolholders and collets, reducing run‑out and vibration. This combination of material and shank design supports stable cutting behaviour and fewer tool changes, contributing to predictable maintenance intervals and lower production downtime.

Optimised geometry and feeds for NC production

With a nominal 5 mm diameter, spiral length 14 mm and overall length 62 mm, the tool is dimensioned for use on NC machines and conventional drilling rigs. The specification allows a recommended feed of 0.04 mm/rev in steel with tensile strength up to 800 N, providing a balance between efficient material removal and surface quality. The right‑hand cutting direction and compact flute length support fast, position‑accurate spot drilling and chamfering of tapped holes in a single pass, simplifying cycle programming and reducing machining steps.

FAQ

What materials is this centre drill suitable for?
The TECWERK NC centre drill in HSS‑Co is suitable for machining a wide range of steels and general workshop materials; the specified feed of 0.04 mm/rev applies for steel with tensile strength up to 800 N.

Can the tool be used directly before tapping?
Yes. The geometry provides both centring and chamfering in a single pass, preparing the hole for subsequent tapping and improving thread start consistency.

What shank and clamping are required?
The tool has a DIN 1835‑A cylindrical shank and tolerance h8, so it is intended for standard collets and holders compatible with DIN 1835‑A shanks.

Is this item suitable for NC machining centres?
The NC centre drill is specifically designed for NC machines and drill rigs, offering position‑accurate spot drilling and chamfering for automated production.
