Iscar 5100030 Modular Reamer Head Helical Flute 20mm

Product Description

The ISCAR 5100030 is a modular reamer head designed for precision hole finishing in high temperature alloy materials. The helical flute geometry promotes smooth chip evacuation and reduces cutting forces during reaming operations. This head measures 20.00 mm in diameter with a head length of 0.409 inches and carries an h7 hole tolerance rating, making it suitable for applications requiring tight dimensional control. A bright coating is applied to the cutting surfaces. The left-hand cutting direction suits specific spindle configurations and fixturing setups encountered in aerospace and high-temp alloy machining environments. Machinists and tooling technicians working on precision boring and finishing operations are the primary installers of this component.

This modular reamer head is used in CNC machining centers and boring mills where modular tooling systems allow quick head changes without disturbing the full tool assembly. It is particularly suited for finishing bores in high temperature alloys such as those common in aerospace, power generation, and industrial turbine component manufacturing. The h7 tolerance class targets interference and transition fit bore applications where dimensional accuracy is critical. The left-hand cut configuration is selected when workpiece rotation or fixturing requires non-standard cutting direction.

Key Features

• Helical flute geometry supports efficient chip evacuation in difficult-to-machine alloys
• 20.00 mm head diameter with h7 hole tolerance for precision bore finishing
• Left-hand cutting direction for specialized spindle and fixturing requirements
• Bright coating applied to cutting surfaces
• Modular design enables head replacement without removing the full tool from the holder
• Conforms to ISO 13399 tooling data standards

Compatibility

Designed for use with modular reamer systems accepting a 20.00 mm head diameter in left-hand cut configuration. Material application is rated for high temperature alloys. Verify interface compatibility with the specific modular shank or arbor system in use before installation.

Installation Notes

Installation is performed by qualified machinists or tooling technicians familiar with modular cutting tool systems. Ensure the machine spindle is fully stopped and locked out before mounting or removing the reamer head. Confirm the mating shank interface is clean and free of chips or burrs before seating the head to achieve proper torque transfer and runout performance. Follow the tooling manufacturer assembly torque guidelines for the specific modular interface being used.
