150mm Thread Re-Drilling Tool M4 Solid Carbide TiN Coated 3-Flute Self-Centring, 3.3mm Core - TECWERK

Take advantage of the combination of solid carbide construction, TiN coating and a self‑centring, straight‑fluted geometry to remove broken taps reliably and reduce downtime; order the thread extraction drill directly via Metav Werkzeuge or consult the technical advisors if assistance is required.

Thread extraction drill M4 — solid carbide, TiN‑coated, 3‑tooth (TECWERK)

The Thread extraction drill M4 is a purpose‑built solid carbide tool for safe drilling out of broken HSS and HSS‑Co taps in workshop and production environments.

Solid carbide, TiN‑coated cutting head
Self‑centring, straight‑fluted design
Optimised for broken HSS and HSS‑Co taps
Three‑tooth geometry for efficient chip evacuation

Fast and reliable removal of broken taps for uninterrupted workflow

The drill is designed for targeted extraction of fractured taps and threaded tools, combining a solid carbide body with a TiN coating for extended edge life. The self‑centring geometry reduces the need for pre‑alignment, which shortens setup time and lowers the risk of further thread damage. As a result, downtimes are reduced and rework is minimised, supporting continuous production and predictable maintenance cycles.

Precision cutting and controlled chip formation for safe operation

A three‑tooth geometry and straight flutes provide consistent chip formation and evacuation through a dedicated chip length of 15 mm, which helps avoid clogging in blind holes. The cylindrical shank with a 6 mm diameter gives stable clamping in standard toolholders, while the 3.3 mm core hole dimension ensures a compact cutting core for precision guidance. Together, these attributes enable a clean extraction process with less force transfer to the workpiece.

Suitable cutting speeds and versatile application range

The tool is rated for use across a practical speed range of 1,500–3,500 rpm, with an operational recommendation of about 2,100 rpm for many typical M4 cases. That flexibility permits adaptation to different machine capabilities and material conditions. Specifically made for dealing with broken HSS and HSS‑Co taps, the tool is also appropriate wherever a robust, high‑precision solid carbide drill is required for corrective maintenance tasks in metalworking shops.

Practical benefits for workshop and service technicians

Thanks to the combination of TiN coating and solid carbide substrate, the tool offers improved wear resistance and easier cutting performance compared with uncoated alternatives. The straightforward geometry simplifies handling and reduces the learning curve for maintenance teams. For complex cases or unusual materials, Metav’s product specialists can provide application guidance and machining parameter suggestions to ensure effective use in everyday workshop practice.

FAQ

What materials is this tool intended for?
The TECWERK thread extraction drill M4 is designed specifically for removing broken HSS and HSS‑Co taps and is suited to standard steel workshop applications where corrective drilling of threaded tools is required.

Which spindle speed should be used for best results?
A practical operating range for the tool is 1,500–3,500 rpm; a typical recommendation for many M4 applications is approximately 2,100 rpm to balance cutting performance and tool life.

How does the TiN coating benefit the tool?
The TiN coating on the solid carbide body increases wear resistance and improves sliding properties, resulting in more consistent cutting performance and longer tool life during extraction tasks.

Is a special holder required for the 6 mm shank?
The cylindrical shank with a 6 mm diameter fits standard collets and chucks; secure clamping in an appropriate holder is advised to maintain concentricity during drilling.
