The Top Groove & Top Thread system is the most rigid tool on the market. Locking forces in three directions on the insert offer superior resistance to thrust and tangential force. The simplistic design avoids costly set-up errors that can occur with laydown type threading tools. Accepts both threading and grooving inserts. First choice for heavy-duty or high-feed applications. The rigid tool results in better surface finishes. Excellent chip control. Consistent carbide grades provide long tool life. Multiple grooving and threading insert endforms available as standards.
  • Holder shipped with clamp and clamp screw
  • Right hand #3

Best choice for job shop environments. Especially effective for single-point threading of course pitches, Acme, Buttress, and API threads. Best for multi-tooth threading applications. Right-hand holders use right-hand inserts. Left hand holders use left-hand inserts
