Product Overview
Achieve perfect thread forms with our UN Unified Full Profile laydown threading inserts. Designed for the American market, these inserts produce precise 60° threads compliant with UN, UNC, UNF, and UNEF standards.
Featuring a “Full Profile” geometry, these carbide threading inserts cut both the thread groove and the crest (Topping) simultaneously. This ensures the thread is concentric, burr-free, and perfectly sized, making them the superior choice for high-precision threading inserts for lathe operations.
Key Features & Benefits
- The Industry Standard: Our 16er threading inserts are the go-to solution for general machining, covering the vast majority of standard UNC/UNF pitches from 32 TPI down to 8 TPI.
- Heavy Duty Capability: For coarser threads (7 TPI to 4 TPI), we offer larger I.C. sizes (22ER/IR and 27ER/IR) to maintain rigidity and tool life.
- Complete Directional Control: We provide a full range of standard right-hand tools as well as left hand thread insert (EL/IL) options for reverse turning or specific setup needs.
- Micro-Boring Ready: Internal inserts available as small as 1/4″ I.C. (11IR) for small diameter bore threading
