Iscar 4550235 Boring Head 40mm MB40 Modular Bhr Series

Product Description

The ISCAR 4550235 is a single-cutter boring head designed for precision internal diameter machining on CNC machining centers and boring mills. The head features a manual actuation system for diameter adjustment and mounts via an integral MB40 modular connection shank, part of ISCAR's BHR series. With a body diameter of 40 mm (approximately 1.575 inches) and a projection of 80.01 mm (3.15 inches), it is built for stable, accurate boring at moderate reach. The 4550235 covers a bore diameter range from 50.01 mm (1.969 inches) to 68.00 mm (2.677 inches), making it suitable for close-tolerance bore work in steel, cast iron, and similar materials.

This boring head is intended for use in production and toolroom environments where an MB40 modular tooling interface is already in use. Typical applications include finish boring of housings, bearing bores, and cylindrical features on vertical or horizontal machining centers. The integral mount design eliminates adapter stack-up, improving rigidity and reducing runout. It is installed and adjusted by machinists or tooling technicians familiar with modular boring systems.

Key Features

• Single-cutter head with manual diameter adjustment for controlled bore sizing
• Integral MB40 modular connection shank for direct mount without adapters
• Bore diameter range: 50.01 mm (1.969 inches) to 68.00 mm (2.677 inches)
• Body diameter of 40 mm with 80.01 mm (3.15 inches) projection for moderate reach applications
• Part of the BHR series, designed for consistent, repeatable boring performance

Compatibility

Compatible with MB40 modular connection tooling systems. Designed as a direct-mount boring head for machining centers and boring mills equipped with an MB40 interface. Verify spindle taper and modular interface standard before ordering.

Installation Notes

Installation and adjustment should be performed by a qualified machinist or tooling technician. Power down and lock out the machine spindle before mounting or adjusting the boring head. Use the appropriate torque wrench and manufacturer-specified clamping hardware for the MB40 modular connection. Confirm bore diameter setting with a bore gauge or micrometer before initiating a cut.
