NC spot drill D.8 mm — solid carbide, TiAlN, 90° »TECWERK«

NC spot drill D.8 mm is a solid-carbide, right-hand spot drill with a 90° point and a cylindrical shank to DIN 6535-HA for position-accurate pre-drilling and combined centring and chamfering on NC machines and drilling centres

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

Accurate starts and one-pass chamfering for reliable holemaking

The tool delivers precision starts thanks to its 90° geometry and a ground point that anchors the cutting action immediately. Built from solid carbide, the geometry resists deflection and maintains concentricity during rapid indexing on CNC machining centres. The design enables simultaneous centring and chamfering, which shortens cycle times and reduces set-up complexity compared with separate operations. For production environments seeking repeatable hole starts and consistent countersinks, this spot drill supports stable, high-quality hole preparation.

Heat-resistant coating and material versatility for demanding jobs

A TiAlN coating increases thermal tolerance at the cutting edge and reduces adhesion when working with difficult materials. The combination of the coating and the carbide substrate makes the tool particularly suited for high-strength steels, stainless steel and a range of cast and non-ferrous materials. Operators benefit from longer tool life under elevated temperatures and improved surface condition at the entry point. Where material variability is common, this configuration reduces downtime caused by premature wear and decreases the frequency of tool changes.

Shank standard, cutting direction and recommended feed for process integration

The cylindrical shank complies with DIN 6535-HA, ensuring secure clamping in standard collets and holders and supporting stable machining at higher spindle speeds. The drill is right-hand cutting, optimised for conventional machine set-ups. For typical steel workpieces with cutting forces up to 800 N, a feed of 0.1 mm/rev is recommended to balance chip formation and tool life. These parameters translate directly into predictable machining cycles and improved throughput when the tool is programmed into NC routines.

Practical benefits for shop-floor workflows and maintenance

Using a dedicated spot drill of this specification reduces the risk of wandering during initial penetration and improves thread preparation when used prior to tapping. The robust carbide body and coating lower the frequency of replacements, resulting in fewer interruptions to batch production. Documentation of repeatable feeds and the standard shank format also simplifies inventory and toolholder planning, supporting lean material handling and consistent set-up times across multiple machines.
