INTERNAL TOOL HOLDERS WITH COOLANT BORE

Tool holders for cutting internal threads. These holders improve on the basic internal tool holders by adding an integrated coolant bore. The coolant liquid helps to evacuate the chips, which helps to maximize tool performance, as well as extend the life of the insert.

Features:

TOOL HOLDERS WITH 3.5° HELIX ANGLE

Tool holders for internal thread turning jobs. Unlike the standard holders that use a 1.5° helix angle, the tool holders that belong to the current product line use 3.5°.

Typically, one would consider using such a tool holder in case of a large-pitch thread with a relatively small diameter.

CARBIDE SHANK THREADING BARS

These carbide shank bars can be used to cut internal threads. They are especially well-suited for deep small bores with a long overhang, or for use in other situations, where chatter and deflection are expected. These bars have an integrated coolant bore, which helps with chip evacuation. This helps to maximize tool performance, as well as extend the life of the insert.

Features:

  • Left-hand and right-hand variants available
