NC spot drill D 3 mm, HSS‑Co, TiN, 90° point (TECWERK)

The NC spot drill D 3 mm, HSS‑Co, TiN, 90° point is a precision spot‑drilling tool for centring and countersinking on NC machines and drilling centres, designed for fast, position‑accurate starts and combined centring and chamfering operations.

• HSS‑Co construction for high wear resistance
• TiN coating for extended tool life
• DIN 1835‑A cylindrical shank for direct mounting
• 90° point for precise centring

Consistent precision from material to geometry

Constructed from HSS‑Co, this spot drill delivers improved resistance to abrasion and thermal loads compared with standard high‑speed steels. The combination of HSS‑Co and a TiN surface layer reduces flank wear and maintains cutting geometry longer, which supports consistent hole quality during extended runs. The result is fewer reworks and a reliable, repeatable centring performance.

Optimised for NC machining efficiency

With a 3 mm diameter and a 90° point angle, the tool is designed for quick, position‑accurate starts on automated equipment. The DIN 1835‑A compliant cylindrical shank allows secure mounting in chucking systems on NC machines and drilling centres, reducing setup time and improving process stability. Measured feeds and geometry promote efficient cycle times without sacrificing accuracy.

Simple handling and productive process integration

The right‑hand cutting orientation and the standard shank form facilitate straightforward integration into existing tool cycles. The tool enables combined centring and countersinking in a single pass, eliminating extra operations and simplifying tool inventories. Its standardised shank also eases interchangeability between setups, reducing machine downtime during tool changes.

Practical operating data and suitable workpiece materials

For machining in steel with a tensile strength up to 800 N, the recommended feed is 0.03 mm/rev, which balances chip formation and surface finish for the sizes concerned. The tool’s tolerance h8 on the diameter supports precise positioning in fixtures, while the TiN coating helps when moderate heat or adhesive wear might otherwise shorten tool life. Use on NC machines and drilling centres for reliable pre‑drilling and thread‑preparation tasks.

FAQ

What materials can this spot drill machine effectively?
The TECWERK NC spot drill D 3 mm, HSS‑Co, TiN, 90° point is suitable for steel up to a tensile strength of 800 N and for general pre‑drilling and centring tasks on common workshop steels.

How should the tool be mounted in the machine?
Mount the tool by its DIN 1835‑A cylindrical shank in the machine chuck or holder designed for cylindrical‑shank tooling to ensure concentricity and secure clamping.

What feed should be used for clean centring in steel?
For steels up to 800 N, use a feed close to 0.03 mm/rev to achieve a balance between chip control and surface finish with this tool geometry.

Does the TiN coating improve performance for small diameters like 3 mm?
Yes, the TiN coating reduces adhesive wear and improves sliding properties, which is especially beneficial for small‑diameter tools where heat and friction are concentrated.
