TCMT Inserts Manufacturer & Supplier in China
Source standard and custom TCMT triangular positive inserts for internal turning, external finishing, profiling, and chamfering.
What Is a TCMT Insert?
A TCMT insert is an ISO 60° triangular, 7°-clearance, M-tolerance, positive single-sided turning insert with a fixing hole and chipbreaking geometry. Its positive flank reduces cutting force, while three corners can provide economical indexing in compatible internal or external turning holders.

TCMT Insert Applications
TCMT inserts are selected where their verified shape, clearance, and holder access match the cutting path and setup.
Internal Turning
Boring cuts with adequate bar clearance and chip evacuation.
External Finishing
Lower-force longitudinal turning on stable or smaller components.
Profiling
Moderate contours using the access of a 60° triangular corner.
Chamfering
Edge breaks and chamfers within the holder's permitted approach.
Internal Facing
Bore-bottom or shoulder facing where bar geometry provides clearance.
TCMT Insert FAQ
How is minimum bore size determined for TCMT?
It depends on the complete boring-bar head, screw, chip space, overhang, and clearance rather than the insert IC by itself.
Can every TCMT holder use all three corners?
Corner access depends on holder design, hand, chipbreaker direction, and operation path; confirm with the holder designation.
Why might a 0.2 mm radius be selected?
It can reduce force or enter fine details, but feed capability and edge strength are lower and must be matched to the setup.
What causes chip packing in internal TCMT work?
Insufficient evacuation space, unsuitable chipbreaker engagement, low feed, coolant direction, depth, and bore geometry are common contributors.
How should TCMT equivalency be requested?
Send the full designation and suffix, grade, holder, material, cutting conditions, target finish, and current wear result.
Can TCMT be customized for aluminium?
A sharp polished geometry may be reviewed after alloy, silicon content, coolant, finish target, batch size, and dimensional requirements are known.
