NC spot drill D.6 mm VHM 90° by TECWERK — solid carbide, DIN 6535-HA shank

The NC spot drill D.6 mm VHM 90° is designed for precise spotting and chamfering on numerical control machines and boring mills, combining rigid shank standards with a 90° tip for reliable centring and chamfering in one operation

• Solid carbide construction for rigidity and wear resistance
• Cylindrical shank to DIN 6535-HA for secure clamping
• 90° tip for combined centring and chamfering
• Right-hand cutting for conventional machining

Accuracy that reduces rework and shortens setup times

Manufactured from solid carbide, this spotting tool is dimensionally stable under load and suited to high-production environments where repeatability is essential. The DIN 6535-HA cylindrical shank permits snug clamping in standard toolholders, while the h6 diameter tolerance minimises runout and vibration. For NC operations, the resulting reduction in spindle deviation leads to fewer rejected parts and more predictable cycle times. The 6 mm nominal diameter and close tolerance support fine positioning, which is particularly useful when subsequent threading or reaming follows.

Two-step saving: centring and chamfering in one pass

With a 90° tip geometry the tool performs centring and chamfering simultaneously, so the workpiece is prepared for tapping without a separate operation. This position-accurate approach saves handling time and lowers the risk of misalignment between centre and thread. The tool’s tip form produces a clear, chamfered lead that eases tap entry and improves thread quality, which is a distinct advantage when many holes require consistent results on a production run.

Suitability for demanding materials and defined cutting data

The design is particularly effective on high-strength steels, stainless steels and non‑ferrous metals, as well as various cast materials. The tool is specified for a recommended feed 0.09 mm/rev in steel at forces up to 800 N, enabling predictable material removal under controlled conditions. As the tool is right-hand cutting, conventional spindle directions and tooling strategies are maintained; machining parameters can therefore be integrated easily into existing NC programmes without additional toolpath complication.

Robust dimensions for industrial workflows

Measured dimensions such as 50 mm overall length and 18 mm spiral length provide a compact yet usable reach for most spotting tasks, while the NC machines-compatible shank standard eases tool change and inventory management. The combination of flute length and carbide body supports chip evacuation for short, interrupted contacts typical of centring operations. Specified tolerances and shank standardisation are intended to simplify toolholder selection and to keep toolset-up times to a minimum.

FAQ

What is the primary application of this spot drill?
The TECWERK NC spot drill is intended for position-accurate spotting and simultaneous chamfering on NC machines and boring mills, preparing holes for tapping in one operation.

Which materials can be machined with this tool?
This spotting tool performs well on high-strength steels, stainless steels, cast steel, grey cast iron and non‑ferrous metals as noted in the technical data.

What are the key dimensional specifications for tool setup?
For setup use the 6 mm nominal diameter, 50 mm overall length and 18 mm spiral length; the shank complies with DIN 6535-HA and diameter tolerance h6.

How does the 90° tip angle benefit tapping operations?
A 90° tip creates a controlled chamfer and clear centre mark, which aids tap entry and reduces the likelihood of cross-threading during subsequent threading operations.

Is the cutting direction standard for common machining centres?
Yes, the tool is right-hand cutting and is compatible with conventional spindle rotation and standard NC toolpaths.
