NC spot drill D 8 mm VHM TiAlN 90° by TECWERK — Solid carbide pilot tool with TiAlN coating and DIN 6535-HA shank

The NC spot drill D 8 mm VHM TiAlN 90° is a pilot and chamfering tool for positions‑accurate spotting on CNC machines and boring mills, designed to centre and chamfer threaded holes in a single pass

• Solid carbide VHM for high rigidity
• TiAlN coating for thermal wear resistance
• DIN 6535-HA cylindrical shank h6 tolerance
• 90° point for positioning and chamfering

High‑precision positioning for reliable production starts

The tool is engineered for precision spotting and one‑pass chamfering, which reduces cycle times and eliminates secondary operations. Thanks to the solid carbide grade and the defined 90° point geometry, positional accuracy is maintained when starting holes and preparing thread entries. This results in fewer rejects and less rework on production runs, which improves overall process efficiency for repeatable series work on CNC equipment.

Durable coating and material for demanding applications

A TiAlN coating enhances heat resistance at elevated cutting temperatures and prolongs tool life when machining tougher materials. The combination of the coating and the carbide substrate provides a balance of wear resistance and edge stability, so the cutter withstands hubs of high thermal load. For short‑run and long‑run tasks alike, this extends intervals between tool changes and helps maintain consistent hole quality.

Designed for machining a wide range of materials

The construction and geometry make the tool particularly suitable for high‑strength steels, steel castings, grey cast iron, stainless steels and various non‑ferrous alloys. Its right‑hand cut is optimised for conventional machining directions on NC lathes and milling centres. For steel operations with a cutting force up to 800 N, a recommended feed of 0.1 mm/rev supports secure chip formation and smooth entry without compromising the centring function.

Clear dimensions and machine compatibility simplify integration

The pilot cutter is supplied with a DIN 6535‑HA cylindrical shank in tolerance h6, enabling precise clamping and interchangeability in standard toolholders. Key dimensions such as 8 mm diameter, 60 mm overall length and a 23 mm spiral length are provided to verify fit and reach on the intended machine setup. These specifications ensure straightforward tool selection for programmed drilling and spotting cycles while maintaining reproducible results.
