Review roller-bit quantity, mounting space and cutting paths together. Use one centre and reference plane to check the first pair, full layout and welded assembly.

Tell a missing roller cone from insert loss or a stiff cone. Inspect the leg, preserve the damaged parts and send a numbered tool record for a technical review.

Define roller-bit traceability and inspection records before ordering. Connect component batches, measured features and sample scope to the supplied parts.

Compare a centre fixture with a marked layout plate for roller-bit positioning. Check radius, cutter orientation and height against the selected drawing.

Read the outer cutting path, steel-ring reference and inner cutting path separately. Use the common centre to check the ring and the complete roller-bit layout.

Two historical JM samples illustrate dimensional measurement and brazed-joint inspection. Use the current part drawing to define acceptance limits.

Prepare the cutting diameter, rig connection, ground data and required supply scope for a core-barrel quotation. Include current-tool photos when replacing parts.

Compare welded legs, matched holders and bolted systems before ordering roller bits. Check the existing interface, installation access and replacement scope.

Compare the starting tooth, its numbered position and the surrounding holder. Use repeat photos and a replacement log before interpreting uneven bullet-tooth wear.
