GTN Grooving Inserts Manufacturer & Supplier in China
Source standard and custom GTN carbide grooving inserts from China. Review verified designations, dimensions, applications, holder information, and drawing-based customization requirements.
What Is a GTN Grooving Insert?
A GTN insert is a replaceable carbide parting and grooving insert used in compatible clamping blades. Verified Chinese supply data lists nominal families GTN2 through GTN6, while catalogued actual cutting widths are approximately 2.2, 3.1, 4.1, 5.1, and 6.4 mm. Blade pocket and insert profile must be matched as a system.

GTN Grooving Insert Applications
GTN inserts should be applied only after the insert seat, holder system, cutting width, radius, maximum cutting depth, hand, and operating conditions have been confirmed.
External Grooving
Producing radial grooves on outside diameters after confirming holder seat, width, reach, and center-height alignment.
Parting-Off
Separating bar or component stock with controlled overhang, rigid clamping, coolant access, and chip evacuation.
Shoulder Recessing
Machining a narrow relief near a shoulder where holder access and side clearance have been checked.
Repeated Groove Production
Producing repeat grooves when insert seating, indexing, width control, and inspection method remain consistent.
GTN Grooving Insert FAQ
How should incoming GTN inserts be dimensionally inspected?
Use a documented sampling plan and calibrated optical or contact equipment appropriate to the tolerance. Check width, radius, profile, seating surfaces, edge condition, and lot traceability without contacting a fragile cutting edge incorrectly.
How can edge chipping be separated from normal flank wear?
Inspect the edge under magnification and compare its location and pattern. Random fractures often indicate impact, vibration, chip recutting, or an unstable seat, while progressive uniform wear develops more continuously along the engaged edge.
How should unused GTN inserts be stored?
Keep inserts separated in clean original-style trays, dry, clearly lot-labelled, and protected from edge-to-edge contact. Do not mix trial lots or return used inserts to a new-insert compartment.
Should a worn GTN insert be reground?
Regrinding changes the cutting width, profile, edge preparation, coating, and seating relationship. Treat it as a separately engineered item and validate the revised geometry rather than returning it to service as an unchanged standard insert.
Which records make a production trial useful?
Record part and machine identifiers, lot number, edge index, actual speed and feed, coolant, overhang, cut count or time, measured groove results, chip photographs, and the final wear or failure mode.
Why are GTN widths not exactly the same as the number in the designation?
The verified blade-system data uses nominal family numbers while actual widths include values such as 2.2, 3.1, and 4.1 mm; use the catalogued width and matching blade, not the code alone.
