Take advantage of solid carbide construction and a TiAlN coating together with a 142° point angle for rapid, position‑accurate centring and chamfering; order the NC centre drill directly via Metav Werkzeuge or consult the Metav team for further advice.

NC centre drill D12 mm, solid carbide, TiAlN, 142° – TECWERK

The NC centre drill D12 mm is a precision spot‑drilling and chamfering tool for NC machines and drilling rigs, designed to centre and deburr thread holes in a single pass with a cylindrical shank to DIN 6535‑HB.

• Solid carbide, TiAlN‑coated
• 142° point angle for accurate centring
• Cylindrical shank to DIN 6535‑HB
• Suited to high‑strength steels, cast iron, stainless

Faster, one‑pass centring and chamfering to cut cycle times

The tool achieves rapid, position‑accurate pre‑drilling and countersinking by combining a 142° point angle with a stiff solid‑carbide body. This geometry provides a stable centre with reduced axial run‑out, allowing a precise start for subsequent drilling or tapping operations and cutting setup times. The capability to centre and chamfer in a single operation reduces tool changes and handling, which directly improves throughput on high‑volume NC production runs.

Engineered for demanding materials and continuous performance

Constructed from solid carbide and finished with TiAlN, the drill resists thermal wear and keeps the cutting edges sharper for longer under elevated cutting temperatures. This results in consistent hole quality when working with high‑strength steels, cast iron, grey cast iron, stainless steels and non‑ferrous alloys. The right‑hand cutting geometry maintains reliable chip control and surface finish at the feeds and speeds typical for industrial NC machining, delivering repeatable results across mixed‑material production.

Precision fit and machine compatibility for reliable process integration

The cylindrical shank manufactured to DIN 6535‑HB ensures a tight, concentric fit in standard holders and spindles, while the diameter tolerance h6 secures repeatable positioning in collets. Designed for use on NC machines and drilling equipment, the centre drill is also intended to align with solid‑carbide drills that have point angles between 120° and 140°, enabling accurate transfer of the centre mark. Recommended feed guidance in steel under comparable thrusts is 0.12 mm/rev at up to 800 N, supporting controlled penetration and minimal wander.
