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.
| References | Insert Ø | Body Ø | Upper / lower length | Lower Ø callouts |
|---|---|---|---|---|
| CWT-H1 / CWT-1 / CWT-C1 | 22 mm | 60 mm | 72 / 65 mm | 30 / 38 mm |



CWT-C1
A dark upper-body band distinguishes the illustration; the page does not name its material.
Request this configurationPlate-profile JL / JM / JR teeth
These are a separate shape and mounting interface from the round-shank CWT group. Select the cutting profile and wheel position from the complete assembly drawing.
Some plate-profile tooth assemblies use a welded inner seat; others use a separate insert within an outer holder. On the selected assembly drawing, mark whether the required replacement is the tooth, the inner seat or insert, or the complete holder. Confirm the construction and part reference for that assembly; the tooth profile alone does not identify the holder parts.

JL
JL tooth profile. Match its outline and mounting interface to the selected holder drawing.

JM
JM tooth profile. Match its outline and mounting interface to the selected holder drawing.
Request this configuration
JR
JR tooth profile. Match its outline and mounting interface to the selected holder drawing.
Request this configurationA recorded CWT-1 application
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. Record the condition of the tooth and holder, steel loss beneath the carbide and the condition of the cutting edges.

Match the cutter tooth to your wheel
Send the tooth reference or clear front and side photos, plus photos or a drawing of the holder and retention arrangement. Show the tooth position on the complete cutting wheel and include the machine or wheel reference. List the teeth, holders or retention parts required, with the quantity of each part and the destination.
