GBJ 22pcs 3/8″ Lathe Threading Tool SNR0010K11 Holder with AG60

Description

Product Overview

The GBJ 22pcs 3/8″ Lathe Threading Tool set is engineered to meet the demanding requirements of modern machining environments. At its core is the SNR0010K11 holder, fabricated from premium 42CrMo steel, a material renowned for its high tensile strength, excellent hardness of 89 HRA, and impressive bending strength of 2.6 GPa. This robust construction provides a stable platform for the included AG60 inserts, which feature a CVD coating and a specialized tough fibrous structure that significantly enhances wear resistance and fracture toughness. The inserts themselves are coated with a Ti compound layer, delivering a thin yet hard surface that resists deformation while maintaining sufficient toughness to absorb machining stresses. Complementing the holder and inserts are ten M2.5×6 screws, precision‑machined to ensure a secure fit and reliable torque transmission during both internal and external threading operations. The entire kit is compact, weighing just 11.29 ounces, and is designed for quick tool changes, reducing downtime and increasing productivity on the shop floor.

Usage

This threading tool set is versatile enough to serve a broad spectrum of users, from hobbyist machinists working on small‑scale projects to professional engineers handling high‑volume production runs. The 3/8″ shank diameter (10 mm) and overall length of 125 mm make it compatible with most standard lathe machines, while the included screws enable secure mounting on both external and internal threading applications. Ideal for creating precise M2.5 threads, the tool excels in aerospace component fabrication, automotive part manufacturing, and precision instrument assembly. Its CVD‑coated inserts provide consistent chip evacuation and reduced heat buildup, allowing users to maintain tight tolerances even under heavy cutting conditions. Whether you are threading a stainless‑steel shaft, a brass connector, or a high‑strength alloy component, this set delivers reliable performance and repeatable results.

FAQ

What types of materials can this threading tool handle?

The tool is suitable for a wide range of materials, including carbon steel, stainless steel, brass, aluminum, and high‑strength alloys. The CVD‑coated inserts and robust holder allow it to maintain precision even when machining tougher materials.

How do I install the inserts and screws correctly?

Begin by cleaning the holder’s insert seat to remove any debris. Place the AG60 insert into the seat, ensuring the cutting edge aligns with the tool’s orientation markings. Secure the insert with the provided set screw, tightening it to the recommended torque. Finally, insert the M2.5×6 screws into the designated holes, confirming a snug fit without over‑tightening.

Can this tool be used for both internal and external threading?

Yes, the GBJ set is designed for both internal and external threading operations. The holder’s geometry and the included screws allow you to adapt the tool for a variety of thread profiles, making it a flexible solution for diverse machining tasks.

What maintenance is required to keep the tool performing optimally?

Regularly inspect the inserts for wear and replace them when the cutting edge becomes dull. Keep the holder free of chips and coolant residue, and periodically check the torque of the set screws to maintain proper clamping force. Applying a light oil coating to the shank can also help prevent corrosion.
