Sandvik Coromant 5727558 Indexable Boring Bar 10mm Shank

Product Description

The SANDVIK COROMANT 5727558 is an indexable boring bar designed for internal turning operations on CNC lathes and machining centers. Built to CoroTurn 107 series standards, this steel-body bar features a 10 mm shank diameter and a 12 mm minimum bore diameter, making it suitable for small-bore finish and semi-finish turning. The bar uses a screw clamping method to secure CCMT 06 02 04 inserts and has a neutral rake angle of 0 degrees with a -5 degree lead angle. Overall length is 125 mm (approximately 4.92 inches). Coolant-through capability supports chip evacuation and tool life in demanding bore finishing applications. Machinists and CNC operators install and maintain this toolholder.

This boring bar is intended for internal turning of bores at or above 12 mm in diameter in materials suited to CCMT insert grades. The right-hand cut orientation and -5 degree lead angle are appropriate for standard bore entry configurations. With a center-to-cutting-edge distance of 6 mm and multi-use turning designation, the 5727558 fits common production turning scenarios in both job shop and production environments. It is packaged as a single unit.

Key Features

• CoroTurn 107 series steel boring bar with 10 mm shank diameter
• 12 mm minimum bore diameter for small-bore internal turning
• Screw clamping for secure, repeatable CCMT 06 02 04 insert indexing
• Neutral rake (0 degrees) with -5 degree lead angle for controlled cutting geometry
• Coolant-through design aids chip removal and reduces heat at the cutting edge
• Right-hand cut, compatible with standard CNC lathe toolpost orientations

Compatibility

Designed for use with CCMT 06 02 04 indexable inserts. Fits toolholding setups requiring a 10 mm shank boring bar with a minimum 12 mm bore diameter clearance, consistent with CoroTurn 107 series toolholder specifications.

Installation Notes

Installation is performed by CNC machinists or toolroom technicians. Power down and lock out the machine spindle before inserting or removing the boring bar from the turret or toolpost. Ensure the shank is fully seated and clamped to the required engagement depth per your machine tool specification before running. Use calibrated torx or hex keys appropriate to the screw clamp insert fastener; follow insert manufacturer torque guidelines for the CCMT clamping screw.
