CNC Lathe Internal Threading Boring Bar SNR0013M16 TiN Carbide Inserts

Description

Product Overview

The SNR0013M16 CNC lathe internal threading boring bar is engineered for high‑precision machining in demanding industrial environments. Constructed from 40Cr steel, the shank provides exceptional rigidity while maintaining a compact overall length of 150 mm (5.9 in). The package includes eleven TiN‑coated 16IR AG60 carbide inserts, each designed to handle pitch ranges from 0.5 mm to 3.0 mm, delivering a balance of hardness and low friction that translates into longer tool life and smoother chip flow. The TiN coating further enhances wear resistance and chemical stability, making the tool suitable for a wide variety of steel alloys. All components are finished with a TiN layer to reduce thermal buildup during extended cutting cycles, ensuring consistent performance across thousands of parts.

Usage

This boring bar excels in applications that require internal thread creation within small‑diameter holes, such as bolt manufacturing, gear shafts, and precision instrument components. The right‑hand cutting geometry is optimized for standard metric and UNC/UNF thread profiles, allowing machinists to achieve tight tolerances without the need for secondary operations. Its compact size makes it ideal for CNC lathe setups where tool holder clearance is limited, and the 13 mm shank diameter fits standard collet chucks without modification. Users can quickly swap the included T15 wrench to replace worn inserts, minimizing downtime. The tool’s versatility also extends to light roughing and finishing passes, providing a single solution for both coarse material removal and fine thread finishing.

FAQ

What material is the boring bar made from?

The boring bar is fabricated from 40Cr steel, a high‑strength alloy that offers excellent toughness and wear resistance, making it suitable for demanding machining tasks.

Can the carbide inserts be replaced?

Yes, the package includes a T15 wrench for easy removal and replacement of the 16IR AG60 inserts, allowing users to maintain optimal performance without additional tools.

What thread sizes can this tool handle?

The 16IR AG60 inserts are rated for pitch ranges from 0.5 mm to 3.0 mm, covering most standard metric and UNC/UNF thread specifications used in industrial applications.

Is the TiN coating durable under heavy use?

TiN coating provides a hard, low‑friction surface that resists wear and thermal degradation, ensuring the inserts retain their cutting edge even during prolonged high‑speed machining.

What is the recommended spindle speed for this tool?

While exact speeds depend on the workpiece material, a typical range of 1500‑2500 RPM is effective for steel parts, balancing surface finish and tool longevity.
