Specifications
Material & Construction
Material: High-grade steel, Interface: BSA (Boring System Adapter), Accuracy: High precision, Finish: Precision ground
Explanation: BSA Size & W Dimension
BSA Format: BSA[size]
Boring System Adapter
Standard interface for square shank turning tools
Square Shank Size (Number)
Maximum square shank dimension in mm for turning bars
W Dimension - Tool Square Size
The W dimension indicates the square cross-section size of the cutting tool insert that fits into this holder.
W = 8mm → Fits turning inserts with 8mm × 8mm square cross-section
W = 10mm → Fits turning inserts with 10mm × 10mm square cross-section
Usage: BSA holders are designed for classical external turning tools with square profile shanks. Select the BT taper matching your spindle, then choose the BSA size corresponding to your turning bar's square shank dimension.
BT x BSA Oblique Cutter Boring Bars
BT x BSA Oblique Cutter Boring Bars are specialized tool holders designed for boring and turning operations using square profile turning bars. These holders combine the robust BT taper interface with the BSA (Boring System Adapter) standard, providing secure clamping for classical external turning tools in machining centers. Key Features: • BT Taper Interface: BT40 and BT50 configurations for various machine sizes • BSA System: Standard interface for square shank turning bars • Oblique Design: Optimal clearance for internal boring operations • Multiple BSA sizes: BSA25, BSA30, BSA38, BSA42 for different tool sizes • Precision clamping for square profile tools • High rigidity for stable boring operations • Suitable for CNC machining centers with BT spindles BSA Size Explanation: • **BSA25**: Designed for 25mm square shank turning bars • **BSA30**: Designed for 30mm square shank turning bars • **BSA38**: Designed for 38mm square shank turning bars • **BSA42**: Designed for 42mm square shank turning bars The number indicates the maximum square shank dimension that can be clamped in the holder. These are classical external turning tool holders adapted for use in machining centers. Applications: • Internal boring operations • Turning operations in machining centers • Square shank turning tool holding • Classical turning tool applications • Heavy-duty boring operations • Production machining with turning tools
