EXTERNAL TOOL HOLDERS WITH INTERNAL COOLANT

A unique product line of external tool holders equipped with an internal coolant – enabling a flow of coolant to the cutting edge. This reduces the temperature of the cutting edge while machining, helping to extend the life span of the tool. Additionally, the coolant liquid aids in removal of the chips during operation – improving the cutting performance.

Features:

  • Two coolant connectors (Elbow fitting and top clamp)
  • Available with either ø4 mm or ø6 mm (the default) connectors
  • Left-hand and right-hand variants available
  • Coated holders provide abrasion resistance

Image

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
