Iscar 7003274 Modular Reamer Head 20mm Right Hand

Product Description

The ISCAR 7003274 is a modular reamer head designed for precision hole finishing in metal cutting applications. With a 20 mm head diameter and right-hand cutting direction, this head mounts to compatible modular reamer body systems to produce accurate, smooth bores in production and jobshop environments. It meets ISO 13399 tooling data standards, making it compatible with modern tool management and CAM software workflows. Machinists and toolroom technicians select this style of interchangeable head to reduce tooling inventory while maintaining dimensional accuracy across a range of bore sizes.

This modular reamer head is suited for use in CNC machining centers, lathes with live tooling, and manual boring operations where a 20 mm finished bore diameter is required. The modular design allows the cutting head to be swapped independently from the shank body, reducing replacement cost and setup time. It is used in aerospace, automotive, die and mold, and general metalworking applications requiring close-tolerance hole finishing.

Key Features

• 20 mm head diameter for precise bore finishing
• Right-hand cutting direction for standard spindle rotation
• Modular interface allows head replacement without changing the full tool assembly
• Meets ISO 13399 tooling data standards for CAM and tool management system integration
• Compatible with RM-BNT-3D/5D/8D modular reamer body series

Compatibility

Compatible with ISCAR modular reamer bodies in the RM-BNT-3D/5D/8D series.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Power down and lock out the machine spindle before mounting or removing the reamer head. Follow the tool manufacturer torque and mounting interface guidelines for the specific body series. Ensure the mating body interface is clean and free of chips or debris before seating the head to maintain runout tolerances.
