Specifications
Material & Construction
Material: High-grade steel, Interface: BSB (Boring System B), Accuracy: High precision, Finish: Precision ground
Explanation: BSB Size & W Dimension
BSB Format: BSB[size]
Boring System B
Square cutter interface for 90-degree boring operations
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
W = 13mm → Fits turning inserts with 13mm × 13mm square cross-section
Usage: BSB holders are designed for square cutter boring operations with classical external turning tools. Select the BT taper matching your spindle, then choose the BSB size corresponding to your square shank turning bar dimension.
BT X BSB Square Cutter boring Bars
BT X BSB Square Cutter boring Bars are specialized tool holders designed for square cutter boring and turning operations using square profile turning bars. These holders combine the robust BT taper interface with the BSB (Boring System B) standard, providing secure clamping for classical external turning tools with 90-degree square cutting orientation. Key Features: • BT Taper Interface: BT40 and BT50 configurations for various machine sizes • BSB System: Standard interface for square shank turning bars • Square Cutter Design: 90-degree cutting angle for square boring operations • Multiple BSB sizes: BSB25, BSB38, BSB50 for different tool sizes • Precision clamping for square profile tools • High rigidity for stable boring operations • Suitable for CNC machining centers with BT spindles BSB Size Explanation: • **BSB25**: Designed for 25mm square shank turning bars • **BSB38**: Designed for 38mm square shank turning bars • **BSB50**: Designed for 50mm 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 optimized for square cutter boring operations in machining centers. Applications: • Square cutter boring operations • Internal turning with square cutters • Square shank turning tool holding • Classical turning tool applications in machining centers • Heavy-duty boring operations • Production machining with 90-degree cutting tools
