Sandvik Coromant 5728277 Boring Head 50mm Body 55-70mm Bore

Product Description

The SANDVIK COROMANT 5728277 is a boring head designed for precision internal diameter machining in metalworking and manufacturing environments. With a 50 mm body diameter and a bore diameter range of 55 mm to 70 mm, this head provides adjustable boring capability across that span. It is installed on compatible boring bars or modular tooling systems and is used by machinists and toolroom technicians on CNC machining centers and manual boring mills. The unit weighs approximately 2.16 pounds, making it a compact but solid tooling component suited for production and repair work.

This boring head is applicable to internal boring operations where hole diameters fall between 55 mm and 70 mm. It fits into setups requiring repeatable bore sizing on ferrous and non-ferrous workpieces. Typical use cases include production machining of housings, bores, and cylindrical cavities where dimensional accuracy is critical. It is suited for shop-floor use in manufacturing facilities, job shops, and toolrooms running standard or tight-tolerance boring operations.

Key Features

• 50 mm body diameter for compatibility with standard boring tool interfaces
• Bore diameter range of 55 mm to 70 mm for adjustable internal machining
• Compact form factor at 2.16 pounds for reduced spindle load
• OEM replacement-grade component from SANDVIK COROMANT tooling line

Compatibility

Designed as an OEM-style replacement boring head for modular boring systems accepting a 50 mm body diameter interface. Specific system compatibility should be verified against the end-user machine and toolholder configuration prior to ordering.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician familiar with boring bar assemblies and modular tooling systems. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before mounting or adjusting the boring head. Verify interface fit and secure all locking screws to manufacturer specification using appropriate torque tools before initiating any cutting operation. Confirm bore diameter setting within the 55 mm to 70 mm range before taking a trial pass.
