CCMT Inserts Manufacturer & Supplier in China
Source standard and custom CCMT positive turning inserts for internal machining, light external turning, and finishing, with size, edge, grade, and coating matched to the application.
What Is a CCMT Insert?
A CCMT insert is an ISO 80° diamond, 7°-clearance, M-tolerance, positive turning insert with a fixing hole and chipbreaking geometry. Its positive flank reduces cutting force and supports internal turning and finishing, while the two principal cutting corners are used from one face in compatible screw-clamp holders.

CCMT Insert Applications
CCMT inserts are commonly used where a positive cutting action, manageable cutting force, and access within bores or compact holders are required.
Internal Diameter Turning
Boring and internal longitudinal cuts where the holder and bore provide adequate chip evacuation.
Internal Facing
Facing shoulders or bore bottoms within the reach and clearance limits of the selected bar.
Light External Turning
Low-force external cuts on smaller components or less rigid setups.
Finishing
Fine stock removal with a radius and chipbreaker selected for finish and chip control.
Profiling and Chamfering
Light contouring and edge features when the holder orientation provides access.
CCMT Insert FAQ
How small a bore can use a CCMT insert?
The minimum practical bore is governed by the complete boring-bar head, screw, chip space, overhang, and required clearance—not by insert IC alone.
What causes chatter with CCMT boring tools?
Excessive bar overhang, insufficient bar stiffness, an unsuitable radius, loose seating, or unstable cutting data are common causes; provide the bar diameter and overhang for review.
Should a ground or molded CCMT edge be specified?
Ground edges may suit demanding sharpness or dimensional requirements, while molded options can be more economical; the correct choice depends on material, finish, and edge-strength needs.
Can CCMT inserts be supplied for non-ferrous materials?
A sharp, polished, usually uncoated geometry can be evaluated for non-ferrous work, but alloy, silicon content, finish target, and cutting data are needed.
What seat details are needed for replacement matching?
Send the holder designation plus clear photos or measurements of the seat, screw, shim if present, and current insert marking.
How is a custom CCMT insert inspected?
Inspection planning should identify datum surfaces and required checks for IC, thickness, hole, corner radius, edge condition, and any drawing-specific feature before production approval.
