DRILLNOVA / ROTARY DRILLING TOOLS
Trench cutter teeth
Two distinct cutting systems: round-shank CWT teeth and plate-profile JL / JM / JR teeth. Compare their body geometry and mounting interfaces before choosing a wheel replacement.

Round-shank CWT teeth.
CWT-H1, CWT-1 and CWT-C1 share the catalogue dimensions below, while the illustrated upper-body profiles differ. The H1 illustration has a ridged ring zone; CWT-1 has a plain profile; CWT-C1 shows a dark upper-body band. The band material is not specified in the supplied catalogue.



CWT-C1
A dark upper-body band distinguishes the illustration; the page does not name its material.

The rotary-drilling brochure documents CWT-1 in granite at the TianGui Intercity Railway project, Guangzhou, in December 2023. No timed comparison or measured wear result is provided.
For a trial on another wheel, record the initial tooth layout and inspect fixed positions after defined drilling intervals. Include holder rotation or movement where applicable, steel loss beneath the carbide and the condition of the cutting edges.
