12mm NC Spot Drill HSS-Co TiN 90° For Precise Centering And Countersinking, Cylindrical Shank DIN 1835-A - TECWERK

Benefit from the HSS‑Co construction and TiN coating combined with a DIN 1835‑A cylinder shank for repeatable, position‑accurate pilot drilling and simultaneous chamfering on NC machines and boring mills; order directly via Metav Werkzeuge or consult the Metav team for application support.

TECWERK NC centre drill D 12 mm, HSS‑Co, TiN, 90°

The TECWERK NC centre drill D 12 mm is designed for position‑accurate pilot drilling and one‑pass chamfering in production environments on NC machines and boring mills.

• Solid cobalt HSS construction
• Cylinder shank DIN 1835-A
• Right-hand cutting geometry
• Centre-drill and chamfer in one pass
• For NC machines and boring mills

Precision and durable cutting for high throughput

The tool combines HSS‑Co base material with a TiN coating to extend tool life under continuous use. The 90° tip geometry gives consistent entry and guidance for subsequent machining steps, while the DIN 1835‑A cylinder shank ensures secure clamping in standard toolholders. These technical choices translate into reduced rework and stable cycle times for serial production.

One operation: centring and chamfering to save cycle time

Designed for simultaneous centring and chamfering, this pilot drill reduces machining steps by performing two operations in a single pass. The right‑hand cutting geometry and optimised tip form enable clean chamfers and accurate hole positioning, so setups are simplified and downstream threads align reliably. The result is measurable time savings on high‑volume tasks.

Clear operating window and recommended feed

The tool is specified for a feed of 0.1 mm/rev in steel at cutting resistances up to 800 N, giving a defined machining window for process planning. The rated feed and material balance help planners and operators calculate spindle speeds and cycle times with confidence, supporting predictable production output on NC equipment.

Practical compatibility and handling benefits

With a standard cylinder shank, the centre drill fits common holders without adapters, simplifying tool changes at the machine. The combination of TiN coating and solid cobalt substrate provides corrosion resistance and wear performance suitable for repeated entry operations, making the tool a dependable choice for busy workshops and production lines.

FAQ

What materials can this centre drill handle?
The TECWERK NC centre drill is made from HSS‑Co and, with its TiN surface, is suitable for a wide range of steels; the specification includes a feed recommendation of 0.1 mm/rev in steel at loads up to 800 N.

Is the shank compatible with standard toolholders?
Yes; the cylinder shank complies with DIN 1835‑A, enabling secure clamping in standard holders on NC machines and boring mills.

Can this tool perform both centring and chamfering in one pass?
The geometry and tip design allow simultaneous centre‑drilling and chamfering, reducing the number of operations required for threaded or assembled holes.

How does the TiN coating help in production use?
The TiN coating increases surface hardness and reduces friction, extending tool life during repeated entry operations and improving consistency across long production runs.

Is the feed rate fixed or adjustable?
The tool has a recommended feed in steel of 0.1 mm/rev at up to 800 N cutting resistance; actual feeds can be adjusted within process parameters to suit machine capability and workpiece requirements.
