Spring Steel Extended Anti-Vibration Internal Boring Bar SCLCR06/SCLCR09, Hardened CNC Internal Turning Tool Holder 6mm~25mm Shank

S-SCLCR Spring Steel Anti-Vibration Extended Internal Boring Bar

This series CNC internal boring bar is manufactured from premium hardened spring steel with excellent anti-vibration performance, available in shank diameters S06, S08, S10, S20 and S25, matching SCLCR06 and SCLCR09 heads for CCMT indexable inserts. The extended shank design supports deep bore machining on CNC lathes with stable cutting rigidity.

The 95° entering angle SCLCR geometry with screw clamping system firmly locates the insert and ensures precise cutting positioning. Optimized spring steel substrate effectively suppresses cutting chatter during deep hole boring, reducing vibration marks and improving inner bore surface finish for steel, stainless steel and alloy steel workpieces.

Each tool holder undergoes strict dimensional inspection and hardness testing to guarantee consistent accuracy and long service life. Fully compatible with standard CCMT06 and CCMT09 carbide inserts, it is widely applied in precision hardware, mold and automotive parts deep bore turning and profiling operations.
