At Technidrill, we put our engineering expertise to work for drillers in mining production and quarries through our TD Range and T flat face bits. Designed specifically for top hammer drilling, this product line enhances operational efficiency, tool reliability, and overall productivity in demanding field conditions.

T Series – Built for tough drilling tools

The TD Range “T” series includes T flat face bits, engineered for high-performance drilling. Available in T38, T45, T51, and GT60, these bits feature various button shapes—round, semi-ballistic, and ballistic—to meet different rock fragmentation needs. You can also choose between a retrac skirt or a straight skirt to optimize stability and improve cuttings evacuation.

Type T extension rods – Full compatibility

Our type T extension rods are compatible with PINxPIN couplings and threaded sleeves across T38 to GT60. PINxBOX rods in T45, T51, and GT60 come in standard lengths of 1 m, 3.05 m, 3.66 m, and 4.27 m, offering flexibility for various drilling depths. Secure connections using BOXxBOX and PINxBOX adaptors or couplings ensure maximum durability on site.

Why choose Technidrill’s T flat face bits?

• Extended tool life with high-strength European steel for enhanced resistance to wear.

• Optimized design enables faster, cleaner cuttings evacuation, minimizing downtime.

• Lower operating costs thanks to long-lasting components that reduce the need for frequent replacements.
