NC Spot Drill D.3 mm HSS‑Co 120° — TECWERK centre/spot drill

The NC Spot Drill D.3 mm is a position‑accurate spot‑drilling tool for NC machines and drilling centres, combining centring and chamfering in a single operation.

• HSS‑Co for high wear resistance
• Cylindrical shank to DIN 1835‑A
• 120° point for precise centring
• Single‑pass centring and chamfering

Reliable performance for NC machining cycles

The tool is manufactured from HSS‑Co, offering improved wear resistance and heat tolerance compared with conventional high‑speed steels, which supports consistent performance under continuous operation. The DIN 1835‑A cylindrical shank ensures secure clamping in standard holders, reducing runout and improving positional accuracy. With right‑hand cutting geometry and a 120° point, the tool creates a clear centre mark and chamfer in one pass, shortening setup times and minimising the need for secondary drilling operations.

Shorter cycle times through combined centring and chamfering

By merging the functions of a pilot centre and a countersink, the centre drill enables immediate thread preparation and reliable tool entry for subsequent drills or taps. The single‑pass approach reduces handling and machine idle time, translating directly into higher throughput on both NC machines and manual drilling centres. The design supports a steady feed strategy that keeps cuts stable, lowering the probability of wandering or false starts when processing small or deep workpieces.

Measurable cutting data and process limits

The tool is specified for position‑accurate and fast spot‑drilling with a recommended feed in steel up to 800 N: 0.03 mm/rev, providing a clear process parameter for programming and setup. Such data helps planners and operators calculate cycle times and assess tool life under defined cutting conditions. Compatibility with standard machine tool holders and the concise feed recommendation make process integration straightforward, especially in batch or serial production environments.

Workshop advantages and supplier reliability

The robust construction and standardised shank reduce the frequency of tool changes and simplify inventory management. Metav’s role as a quality filter for the European market offers additional assurance: established logistics from Emmerich and a broad product range support uninterrupted supply and accessible technical advice. For shops seeking to streamline production without compromising precision, this tool presents a pragmatic choice that supports reproducible results and predictable maintenance cycles.

FAQ

What materials can this spot drill process?
The TECWERK NC Spot Drill D.3 mm, made from HSS‑Co, is specified for use in steel with a recommended feed of 0.03 mm/rev at loads up to 800 N and is suitable for typical workshop steel grades within those limits.

Is the shank compatible with standard holders?
Yes. The tool features a cylindrical shank to DIN 1835‑A, enabling secure clamping in standard tool holders used on NC machines and drilling centres.

Can the tool perform centring and chamfering at the same time?
Yes. The NC spot drill is designed to combine centring and chamfering in a single pass, reducing setup time and supporting faster cycle times.

What cutting geometry does the tool use?
The centre drill employs a 120° point with right‑hand cutting geometry, optimised for precise positioning and clean entry for subsequent drilling or tapping operations.
