Tunneling & Construction
Carbide Solutions for Civil Engineering
From road milling to tunnel boring, our carbide tips and inserts are engineered for the specific wear mechanisms and impact conditions encountered in construction and civil engineering applications.

Applications & Grade Recommendations
Select the application that matches your operation. Each card shows the recommended Harttek grades and their specific advantages.

Road Milling / Cold Planing
Purpose-built grades for road surface removal equipment. Our carbide tips deliver long tool life and consistent cutting performance in both cement and asphalt milling operations.
Enhanced wear resistance for the abrasive conditions of concrete and cement-stabilised surfaces.
Coarser grain for improved toughness in the lower-abrasion, higher-impact conditions of asphalt removal.

Tunneling
Carbide inserts for tunnel boring machines and raise boring equipment. Our tunneling grades address the two primary failure modes: abrasive wear and thermal cracking.
Enhanced microstructure for maximum tool life in abrasive rock formations where wear is the dominant failure mechanism.
Coarser grain with enhanced binder for resistance to thermal fatigue cracking in high-heat tunneling operations.

Rotary & Pick Tools
Carbide tips for rotary cutting tools, point-attack picks and conical cutters used in mining, trenching and foundation drilling applications.
Balanced grades offering good wear resistance and toughness for standard pick tool and rotary cutter applications.
Recommended for demanding applications where thermal cracking and abrasive wear occur simultaneously.

Custom Development
When standard grades do not meet your requirements, our engineering team develops tailored carbide grades and shapes optimised for your specific application conditions.
Bespoke cobalt content, grain size and binder formulation engineered to your operating parameters and failure analysis data.
Non-standard tip geometries, button profiles and insert designs manufactured to your drawings or co-developed with our engineers.
Why Harttek for Construction
Application Engineering
Our engineers analyse your wear patterns, failure modes and operating conditions to recommend the optimal grade and geometry.
Consistent Quality
Every batch is tested to strict TRS, hardness and density specifications. Consistent powder processing ensures repeatable performance.
