The Sandhog CNC Chuck is a cutting tool system with high-precision design, specifically developed for thread cutting using replaceable tungsten carbide inserts. This professional chuck is meticulously engineered to deliver superior performance in CNC lathe machining, ensuring exceptional stability, durability, and cutting accuracy for both external and internal thread cutting.

Technical specifications

Precision Design

The chuck features a robust construction with a clearance accuracy of 0.02 mm, ensuring a tight fit between the insert and the body. This level of precision guarantees minimal vibration and maximum cutting stability during the thread cutting process.

Excellent material quality

The chuck is made of high-quality alloy steel 42CrMo, fully forged, and possesses excellent wear resistance, strength, and rigidity. Advanced heat treatment technologies ensure uniform hardness distribution throughout the body, extending service life even under intensive machining conditions.

Versatile Applications

The designation 22ER/IR indicates compatibility with external and internal right-hand thread machining. The 4.0TR size is ideal for medium-sized threads, while the system also supports 5.0TR and 6.0TR inserts for machining larger threads.

Advantages

High Efficiency: The holder design minimizes setup time and maximizes cutting efficiency, thereby reducing the overall machining cycle time.
Excellent surface finish: precision construction ensures clean and accurate threads, as well as excellent surface quality, which generally eliminates the need for subsequent finishing.
Economic Efficiency: The combination of a robust design and compatibility with standard tungsten carbide inserts provides excellent cost-effectiveness throughout the tool's service life.
Broad Material Compatibility: Suitable for thread cutting on various materials, including steel, stainless steel, cast iron, and other metals.

Applications

This holder system is widely used in various industries:
Automotive industry: thread cutting on engine, transmission, and suspension components
Aerospace industry: precision thread cutting on key aircraft components

General machinery: production of bolts, shafts, and other threaded parts

Oil and Gas Industry: Threading of Pipeline Fittings and Valve Components
