double-sided turning tool holder

The double-sided turning tool holder is a specialized tool that allows simultaneous installation and use of two inserts in opposite directions. This design increases productivity and reduces tool change time during turning operations. The holder is typically made from alloy steel with a hardness of 50 to 62 Rockwell C, offering high resistance to pressure and wear. Its overall length ranges from 120 to 280 millimeters, with a square or rectangular cross-section measuring 16×16 to 32×32 millimeters. The rake angle in these holders is adjustable between 4 and 7 degrees, and the insert locking system is usually a high-strength set screw or clamping mechanism.

In the design of the double-sided turning tool holder, the length-to-cross-section ratio is kept below 5:1 to reduce tool vibration and maintain cutting accuracy. This tool can be manufactured according to ISO 5608 and ISO 10889 standards. Its weight varies between 0.5 and 1.6 kilograms depending on dimensions. TiN and TiAlN coatings ensure wear and heat resistance up to 800°C. When used with carbide inserts, this holder can support cutting speeds up to 240 meters per minute.
