Product Overview

Maximize your workshop’s efficiency with our 55° Partial Profile laydown threading inserts. Specifically engineered for 55° British Standard threads (such as BSW, BSF, and BSP/G), these tools feature a non-topping geometry.

Unlike full profile tools, these threading inserts for lathe applications cut the thread groove without modifying the major or minor diameter. This design allows a single insert grade to machine multiple pitches, significantly optimizing your tool inventory.

  • The “Universal” 55° Solution: Our 16er ag55 threading insert is the industry standard for versatility, capable of machining pitches from 0.5mm to 3.0mm (48-8 TPI) without a tool change.
  • Broad Inventory: We supply a complete range of threading inserts, from small 5/32″ I.C. inserts for internal boring up to heavy-duty 5/8″ I.C. tools.
  • Reverse Machining: To meet all turning requirements, we offer specific left hand thread insert options (such as 16EL AG55) alongside standard right-hand tools.
