TECWERK NC spot drill D 12 mm, solid carbide, 90°

The TECWERK NC spot drill D 12 mm is a solid‑carbide, 90° centre drill designed for position-accurate spot drilling, centring and chamfering on NC machines and boring mills

• Solid carbide with cylindrical shank DIN 6535‑HA
• 90° point for centring and countersinking
• Right‑hand cutting for fast, precise entry
• Suitable for stainless and high‑strength steels

Precision entry and shorter cycle times for NC setups

The solid‑carbide construction and DIN 6535‑HA cylindrical shank ensure rigid clamping and consistent concentricity, which translates into repeatable drilling cycles on CNC machines and boring mills. Using a 90° point allows combined centring and chamfering, so a single pass creates a precise entry and a chamfered edge for subsequent tapping. The specified feed guideline of 0.12 mm/rev in steel (up to 800 N) helps maintain tool life while keeping cycle times low. For workshops seeking reliable first‑hole accuracy, this approach reduces repositioning and inspection steps, increasing throughput without compromising hole quality.

Broad material compatibility reduces tooling variants

Designed for demanding substrates, the tool is particularly effective in high‑strength steels, cast steel, grey cast iron, stainless steels and a range of non‑ferrous metals. The combination of a robust carbide body and a 90° geometry provides controlled chip formation and stable cutting under interrupted entry conditions. This results in fewer burrs and cleaner edges, which eases downstream operations such as tapping and finishing. By choosing a single centre drill that covers multiple materials, machine shops can reduce the number of dedicated spot drills required and simplify inventory management.

Machine‑compatible design that supports process reliability

Optimised for NC machines and drilling rigs, the right‑hand cutting geometry promotes secure penetration and predictable chip flow during rapid positioning cycles. The cylindrical shank matches standard toolholders complying with DIN 6535‑HA, enabling straightforward integration into existing tool setups. The tool’s ability to centre and chamfer in one operation minimises handling and alignment errors, supporting a smoother production flow. Combined with Metav’s quality filter and distribution from Emmerich, purchasing this centre drill supports consistent availability and reliable part production across serial and small‑batch work.
