Internal Turning Tool Holder | Precision Boring Bars for CNC Machining

Our internal turning tool holders, also known as boring bars, are specially engineered for high-precision internal turning, boring, and facing operations on CNC lathes and turning centers. These boring tool holders deliver excellent rigidity, vibration resistance, and cutting accuracy—making them an essential tool for deep-hole and small-diameter machining tasks.

High-Precision Boring Bars for Internal Turning

Constructed from premium alloy steel or tungsten carbide, our internal turning holders are built to withstand the demands of high-speed machining. Designed to accommodate a variety of standard inserts (such as CCMT, DCMT, or TPMT), they ensure consistent surface finish and dimensional accuracy in internal features, bores, and holes.

Key Features

• Available in steel and solid carbide options for different machining conditions
• Compatible with ISO standard turning inserts
• Ideal for boring, facing, and internal threading
• Excellent chip evacuation and anti-vibration performance
• Suitable for stainless steel, alloy steel, cast iron, and aluminum

Applications

Perfect for use in CNC turning centers, horizontal lathes, and Swiss-type machines, our boring bars are trusted across the aerospace, automotive, mold-making, and precision manufacturing industries.
