NC spot drill D 3 mm (solid carbide, TiAlN, 90°) — TECWERK

A NC spot drill D 3 mm engineered for precise positioning and rapid spot drilling on NC machines and drilling centres, suitable for high-strength steels, castings, stainless steels and non‑ferrous metals.

• Solid carbide (VHM) construction
• TiAlN coating for heat resistance
• 90° point for precise centring
• DIN 6535-HA cylindrical shank

Accurate first-hole positioning for stable production

The centre-stage benefit of this spot drill is its ability to deliver repeatable accuracy at the outset of every drilling operation. With a 90° point geometry and a tolerance of h6 on the diameter, the tool provides reliable centring that reduces subsequent rework and scrap rates. The DIN-compliant cylindrical shank guarantees consistent seating in toolholders, which translates into stable tool run-out and improved process control on NC machines and drilling centres.

Coating and material choices that extend tool life

Manufactured from solid carbide, the drill combines edge stability with high rigidity for demanding applications. The TiAlN surface treatment increases thermal resistance and wear protection, making the tool particularly effective when machining high-strength steels, stainless steel and non‑ferrous metals. In practical terms, the coating and material pairing deliver longer tool life and more predictable tool-change intervals, helping to lower overall machining costs. Recommended cutting parameters include a feed of 0.05 mm/rev in steel under specified cutting forces, enabling controlled chip formation and consistent hole quality.

Compact dimensions and machine compatibility for efficient workflows

Designed with a 50 mm overall length and a 10 mm flute, this spot drill balances accessibility in confined setups with enough flute length to evacuate chips reliably during short plunge operations. The right-hand cutting geometry and the DIN 6535-HA cylindrical shank ensure compatibility with standard toolholders and automatic tool changers. By combining centring and light countersinking in a single operation, the tool reduces set-up steps and cycle time, supporting higher throughput and more efficient process chains in production environments.

FAQ

What advantage does a 90° point give for centring?
The 90° point concentrates the initial contact area to produce a clear, stable centre mark; the NC spot drill D 3 mm (TECWERK, SKU 2000865810NW) therefore ensures accurate guidance for subsequent drills and reduces wander.

Is the tool suitable for stainless steel and hardened materials?
Yes. The combination of solid carbide and TiAlN coating makes the tool suitable for stainless steel and many high-strength alloys; however, machining parameters should be adjusted according to material grade and hardness.

How does the TiAlN coating affect process reliability?
TiAlN provides thermal and oxidation resistance at high cutting temperatures, improving tool life and maintaining cutting-edge stability, which supports consistent hole quality in continuous production.

Can the drill be used in automated NC tool changers?
The cylindrical shank to DIN 6535-HA allows secure seating in standard holders and compatibility with automatic tool changers, facilitating integration into automated machining cells.

What machining benefit does centring and countersinking in one pass provide?
Combining centring and a light countersink in a single operation reduces handling and set-up time, improving cycle efficiency and ensuring aligned threaded holes for faster assembly.
