Iscar 4509646 Boring Bar Modular Adapter 1.5 in

Product Description

The ISCAR 4509646 is a modular boring bar adapter designed to extend and connect boring bar assemblies in CNC turning and boring operations. With a 1.5 inch bore diameter and a C6 connection size, this adapter provides a rigid, accurate interface between the machine spindle and the boring bar. Internal coolant delivery channels direct cutting fluid directly to the cutting zone, improving chip evacuation and extending tool life in deep-bore applications. The 0.4724 inch lock screw secures the boring bar within the adapter. This component is installed by machinists and tooling technicians in production and job-shop environments.

This modular adapter is suited for internal turning and boring operations on CNC lathes and machining centers where a C6 modular connection is required. The internal coolant feature makes it particularly well suited for deep-bore applications where flood coolant cannot reach the cutting edge effectively. The 2.756 inch bore depth accommodates standard boring bar shanks in that size class. Typical use includes precision diameter boring in steel, stainless, cast iron, and high-temperature alloys.

Key Features

• C6 modular connection for compatibility with standard C6 tooling systems
• Internal coolant delivery directs fluid to the cutting zone for improved chip control
• 1.5 inch bore diameter accepts standard boring bar shanks
• 2.756 inch bore depth for secure shank engagement
• 0.4724 inch lock screw thread for positive, repeatable clamping
• 2.953 inch body diameter and 4.134 inch body length provide a robust, low-overhang profile

Compatibility

Designed for use with C6 modular boring bar systems requiring a 1.5 inch bore adapter with internal coolant capability. Consult the ISCAR modular tooling catalog to confirm fitment with specific boring bar shanks and machine interfaces.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the machine spindle is fully stopped and all energy sources are locked out before mounting or removing the adapter. Clean all mating surfaces and confirm the C6 interface is free of chips or debris before assembly. Torque the lock screw according to the tooling manufacturer documentation supplied with the assembly; do not use impact tooling on the lock screw.
