Iscar 4550232 Boring Head 20mm MB20 Modular Bhr

Product Description

The ISCAR 4550232 is a single-cutter boring head designed for precision internal diameter machining on modular tooling systems. With a 20 mm body diameter and MB20 integral modular connection shank, this head fits directly into compatible modular tooling assemblies without an adapter. Manual actuation allows the operator to dial in bore diameter adjustments with control. The head covers a bore range from 22.00 mm (0.866 inches) to 27.99 mm (1.102 inches), making it suited for tight-tolerance finish boring where repeatable sizing is critical. It belongs to ISCAR's BHR series, a line built around modular boring configurations for CNC machining centers.

This boring head is used in precision machining environments including job shops, production facilities, and tool rooms running CNC vertical or horizontal machining centers equipped with modular tooling interfaces. The MB20 modular connection is a compact interface standard common in close-quarters boring applications where a smaller body profile is required. It is installed and adjusted by machinists or tooling technicians and is appropriate for both ferrous and non-ferrous bore finishing operations where dimensional accuracy is the primary requirement.

Key Features

• Single-cutter design for controlled, precise bore finishing
• Manual actuation for direct diameter adjustment at the machine
• MB20 integral modular connection shank for direct mounting into modular tooling systems
• Bore range of 22.00 mm to 27.99 mm (0.866 to 1.102 inches)
• 40.01 mm (1.575 inches) projection from shank face
• BHR series construction for compatibility within ISCAR modular boring configurations

Compatibility

Designed for use with modular tooling systems accepting an MB20 connection interface. Part of the ISCAR BHR series boring head line. Consult ISCAR tooling documentation to confirm compatibility with specific modular shanks and extensions in your setup.

Installation Notes

This boring head is installed and adjusted by qualified machinists or tooling technicians. Ensure the machine spindle is fully stopped and the CNC program is in a safe state before mounting or adjusting the head. Use the appropriate torque tools and follow the modular connection manufacturer's clamping procedure when securing the MB20 interface. Verify runout with a dial indicator after mounting and before cutting to confirm the assembly is within tolerance.
