BMT45-90° External Lock Driven Tool Holder with ER25 Wrench for CNC Lathe

Product Overview

This aftermarket replacement driven tool holder is a BMT45 90 degree external lock tool holder with an ER25 wrench, intended for CNC power lathe applications that use the BMT45 turret interface. A driven tool holder transmits rotational power from the machine turret to a cutting tool so that milling, drilling, and similar operations can be performed on a lathe. The holder is identified by the BMT45-90° designation and accepts ER25 tooling.

Key Features & Performance

• Driven tool holder design that transfers rotary power from the turret to a rotating cutting tool for live tooling operations on a CNC lathe.
• 90 degree configuration positions the tool axis perpendicular to the mounting interface for radial or angular work orientations.
• External lock design allows the tool holder to be secured at the turret mounting interface.
• ER25 collet compatibility for holding suitable ER25 tooling.
• Supplied with a wrench for use with the ER25 collet nut.

Fitment & Compatibility

• for CNC power lathe applications using the BMT45 turret interface

Common Uses

• Replacing a worn, damaged, or malfunctioning driven tool holder on a CNC power lathe.
• Supporting live tooling operations such as milling and drilling on a lathe equipped with a BMT45 interface.
• Servicing the turret tooling setup during routine machine maintenance.
