Iscar 6402762 Boring Bar 0.315 in Min Bore Solid Carbide

Product Description

The ISCAR 6402762 is a solid carbide boring bar designed for small-diameter internal turning and boring operations on CNC lathes and machining centers. It cuts in a right-hand direction and features a TiCN and TiN finish coating over an IC228 grade carbide substrate, which provides wear resistance and edge stability in steel, cast iron, and similar workpiece materials. The minimum bore diameter is 0.315 inches (8.00 mm), the maximum bore depth is 0.0591 inches (1.50 mm), and the overall length is 1.0236 inches (26.00 mm). The shank diameter is 6.00 mm. This bar is suited for machinists and tool-room technicians working tight-tolerance bore finishing passes.

This boring bar is intended for precision internal machining applications where small bore diameters and shallow depths are required. It is well suited to finish boring, counterboring, and port or seat work in ferrous and non-ferrous components. The compact overall length and solid carbide construction make it appropriate for high-speed, low-vibration passes in production and job-shop environments where dimensional consistency is critical.

Key Features

• Solid carbide construction for rigidity and dimensional stability in small-bore applications
• IC228 manufacturer grade carbide substrate for wear resistance in steel and cast iron
• TiCN and TiN dual-layer finish coating for extended tool life and reduced built-up edge
• Right-hand cutting direction for standard lathe and machining center setups
• Minimum bore diameter of 0.315 inches (8.00 mm) for tight-clearance internal work
• Compact 1.0236-inch overall length suits confined tooling envelopes

Compatibility

Designed as an OEM-style replacement or direct tooling selection for CNC lathes and machining centers requiring a 6.00 mm shank, right-hand solid carbide boring bar with a minimum bore diameter of 0.315 inches.

Installation Notes

Installation and tool changes should be performed by a qualified machinist with the machine powered down and in a locked-out, tagged-out state per applicable facility lockout-tagout procedures. Ensure the shank is properly seated and clamped in a compatible boring bar holder or tool block before resuming operation. Do not exceed the rated bore depth or use the bar in bore diameters smaller than the stated minimum, as doing so risks tool deflection or breakage. Handle solid carbide tooling carefully to avoid chipping the cutting edge during setup.
