Iscar 5530132 Helical Boring Bar Solid Carbide Tialn

Product Description

The ISCAR 5530132 is a solid carbide helical boring bar designed for internal turning and bore finishing operations on CNC lathes and machining centers. It features a right-hand cutting direction, a minimum bore diameter of 0.315 inches (8.00 mm), and a maximum bore depth of 0.9449 inches (24.00 mm). The bar is coated with TiAlN for elevated heat resistance and extended tool life in demanding materials. Manufactured to ISCAR grade IC908, this boring bar suits high-speed finishing passes where tight tolerances and consistent surface finish are required. It weighs approximately 0.01 pounds and is sold individually.

This boring bar is suited for small-diameter internal boring applications in production machining environments, including both light interrupted cuts and continuous finishing passes. The 8.00 mm shank diameter makes it compatible with standard ER collet chucks and purpose-built small-bore toolholders common in Swiss-type and gang-tool lathe setups. Machinists working in aerospace, medical device, and general precision component manufacturing will find the IC908 grade appropriate for hardened steels, stainless alloys, and heat-resistant superalloys.

Key Features

• Solid carbide construction for rigidity in small-diameter bore applications
• TiAlN finish coating for heat resistance and extended tool life
• Right-hand cutting direction for standard lathe spindle rotation
• 0.3 mm corner radius for fine finishing and controlled edge geometry
• ISCAR grade IC908 suitable for hardened and difficult-to-machine materials
• 8.00 mm shank diameter compatible with standard small-bore toolholding systems

Compatibility

Designed as an OEM-style solid carbide helical boring bar for use with standard 8.00 mm bore toolholders in CNC turning and machining center applications. No specific model compatibility data was provided in the product input.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Ensure the machine spindle is fully stopped and the control is in an e-stop or safe state before inserting or removing tooling. Use a calibrated torque wrench when clamping the shank in the toolholder to avoid micro-fractures in the carbide. Verify runout with a dial indicator after installation before taking the first cut.
