Horn R105182355TN35 Profile Boring Bar Solid Carbide Tin

Product Description

The HORN R105182355TN35 is a solid carbide profile boring bar designed for internal profiling operations on CNC lathes and machining centers. With a minimum bore diameter of 0.197 inches and a maximum bore depth of 1.181 inches, this bar handles tight-bore profiling work where rigidity and edge geometry are critical. The TiN (titanium nitride) finish coating improves surface hardness and wear resistance, extending tool life in ferrous and non-ferrous applications. The right-hand cut configuration and 0.008 inches corner radius suit general internal profile turning tasks. Machinists and tooling technicians working in precision machining environments are the primary users of this tool.

This boring bar is suited for precision internal profiling in both production and job-shop environments. Its compact geometry, with an overall length of 1.772 inches and a 4.00 mm shank diameter, makes it appropriate for small-bore applications where clearance is limited. The TN35 manufacturer grade indicates suitability for a range of cutting conditions typical in profile boring operations on lathes equipped with small-bore tooling systems.

Key Features

• Solid carbide construction for maximum rigidity and vibration resistance in small-bore applications
• TiN finish coating enhances wear resistance and extends cutting tool life
• Right-hand cut orientation for standard lathe and machining center setups
• 0.008 inches corner radius for internal profile turning with controlled surface finish
• Compact 1.772 inches overall length suits tight-clearance boring applications
• 4.00 mm shank diameter compatible with small-bore tooling holders

Compatibility

Designed as a profile boring bar for use in small-bore internal turning applications requiring a 4.00 mm shank and right-hand cut geometry. Verify toolholder compatibility and minimum bore clearance before installation.

Installation Notes

Installation of this boring bar should be performed by a qualified machinist following the toolholder manufacturer specifications for clamping and overhang. Ensure the machine spindle is fully stopped and the machine is placed in a safe state before changing tooling. Do not exceed the maximum bore depth of 1.181 inches, as excessive overhang beyond rated depth reduces rigidity and risks tool deflection or breakage. Confirm shank seating and runout with a dial indicator before cutting.
