Horn R105051914BCB10 Boring Bar Solid Carbide 4mm

Product Description

The HORN R105051914BCB10 is a solid carbide boring bar engineered for precision internal boring operations on small-diameter workpieces. With a minimum bore diameter of 4.00 mm and an overall length of 25.00 mm, this right-hand cutting tool is built for tight-tolerance applications where rigidity and dimensional accuracy are critical. The 0.20 mm corner radius reduces cutting forces and supports fine surface finishes in confined bore geometries. Solid carbide construction provides the hardness and vibration resistance needed for consistent performance in production and job-shop environments. Machinists and tooling setters working on CNC lathes and boring machines are the primary users of this bar.

This boring bar is suited for small-bore internal turning and finishing operations on CNC turning centers and manual lathes. Its compact geometry makes it appropriate for applications requiring access to shallow or narrow bores. The right-hand cutting direction is the standard orientation for conventional lathe setups. This bar belongs to HORN Series 105, a line designed for micro and small-bore machining where carbide rigidity is essential to maintaining tolerances at reduced diameters.

Key Features

• Solid carbide construction for maximum rigidity and wear resistance in small-bore applications
• 4.00 mm minimum bore diameter enables machining of very tight internal geometries
• 0.20 mm corner radius supports fine surface finishes and reduced cutting forces
• Right-hand cutting direction suits standard CNC lathe and boring machine setups
• 25.00 mm overall length provides adequate reach for shallow bore applications
• Part of HORN Series 105, designed specifically for micro and small-bore internal machining

Compatibility

Designed as an OEM-style tooling component for CNC turning centers and boring machines capable of accepting small-diameter internal boring bars with right-hand cutting orientation.

Installation Notes

Installation and setup should be performed by a qualified machinist or tooling technician. Ensure the machine spindle is fully stopped and the machine is placed in a locked-out, de-energized state before mounting or adjusting the boring bar. Secure the bar in a compatible toolholder with sufficient clamping force to prevent deflection during the cut. Verify bar overhang is minimized to maintain rigidity and dimensional control at the 4.00 mm minimum bore diameter.
