NC spot drill D.8 mm, solid carbide, 120° – TECWERK

The NC spot drill D.8 mm VHM 120° TECWERK is a solid carbide spot drill with a cylindrical shank to enable accurate, rapid spot drilling and chamfering on NC machines and drilling rigs

• Solid carbide for high wear resistance
• 120° tip for secure centring and chamfering
• Cylindrical shank DIN 6535-HA
• Diameter tolerance h6 for precision fits

Precision where it counts

This pilot tool is constructed from solid carbide to deliver consistent edge retention and long tool life under demanding conditions. The combination of a DIN 6535-HA cylindrical shank and h6 tolerance ensures repeatable clamping and a reliable runout, which reduces scrap and rework. For process planners this means fewer setup checks and predictable hole location accuracy for subsequent operations.

One-step centring and chamfering for efficient cycles

Equipped with a 120° tip, the tool performs both centring and chamfering in a single pass, shortening NC cycle times and reducing tool changes. The geometry is optimised for a stable cut and clean entrances, making it particularly suitable for high-strength steels, grey cast iron, stainless steel and non‑ferrous metals. The specified feed guidance of 0.1 mm/rev in steel (up to 800 N) supports steady cutting performance under standard machining forces.

Designed for modern NC machining environments

With an 8 mm diameter, 23 mm fluted length and a total length of 60 mm, this pilot drill suits compact and conventional tool setups on milling centres and dedicated drilling rigs. The right-hand cutting direction and standardised shank format facilitate integration into existing tool holders and automatic tool-changers, enabling short changeover times and consistent positioning on production lines.

Durability that keeps production moving

The combination of a wear-resistant carbide body and stable tip geometry reduces frequency of tool replacement and helps maintain surface quality at the hole entry. Predictable tool life and consistent performance contribute to reduced downtime and lower unit costs over production batches. For technical questions about process parameters or material recommendations, consultation with the supplier can help tailor feeds and speeds to individual machines.

FAQ

What materials can this spot drill work on?
The NC spot drill D.8 mm VHM 120° TECWERK is suitable for high-strength steels, grey cast iron, stainless steels and a range of non‑ferrous metals.

What is the recommended feed for steel?
For steel with cutting forces up to 800 N a feed of 0.1 mm/rev is advised for the TECWERK NC spot drill to maintain stability and tool life.

Is the shank compatible with standard tool holders?
The tool features a cylindrical shank to DIN 6535-HA, which is compatible with standard collets and many automated tool-change systems.

How does the 120° tip benefit hole preparation?
The 120° tip allows for secure centring and simultaneous chamfering, reducing the need for separate operations when preparing holes for tapping or drilling.

What tolerance can be expected on diameter fits?
The drill is supplied with a diameter tolerance of h6 to ensure precise fits and consistent positional accuracy.
