NC spot drill D 8 mm solid carbide 120° TECWERK – Solid‑carbide NC spot drill with DIN 6535‑HA shank

NC spot drill D 8 mm solid carbide 120° TECWERK is a right‑hand spot drill designed for position‑accurate starting holes and chamfering in a single pass on NC machines and boring mills.

• Solid carbide for high rigidity and wear resistance
• 120° tip for accurate centring and chamfering
• Cylinder shank to DIN 6535‑HA for secure clamping
• Suitable for high‑strength, stainless and non‑ferrous metals

Precision start holes and one‑pass chamfering to save cycle time

The solid carbide design provides high rigidity and a long service life under the loads typical of CNC production. The 120° tip gives a defined centring geometry that produces consistent, burr‑reduced start holes and an integrated chamfer in one operation, which shortens cycle times and reduces handling. With right‑hand cutting and a feed guideline of 0.1 mm/rev in steel up to 800 N, the tool is dimensioned for controlled material entry and repeatable hole quality, making it suitable for series production and setup‑sensitive tasks.

Robust shank and secure clamping for reliable machining

The cylindrical shank made to DIN 6535‑HA ensures compatibility with standard toolholders and a secure grip for heavy‑duty NC applications. The combination of shank standardisation and solid carbide body minimises run‑out and vibration, which directly benefits hole concentricity and surface finish. For workshops processing a range of alloys, the geometry is especially effective on high‑strength steels, steel castings, grey cast iron, stainless steels and non‑ferrous metals, reducing the need for frequent tool changes and simplifying tool inventory.

Tailored for NC machines and practical workshop use

Engineered for use on NC machines and drilling centres, the tool permits positions to be picked off accurately and repeatedly, which supports automation and unmanned shifts. The integrated centring and chamfering function reduces process steps and potential error sources during thread preparation. Maintenance is straightforward thanks to the wear‑resistant carbide; worn items can be replaced without complex re‑calibration of the process. For questions on integration into an existing toolchain or to confirm cutting data for specific alloys, Metav’s technical advisers provide targeted guidance.
