Magnum 1/4 Inch Insert 3/8 Inch Shank Indexable Tool Holder (BL6)

Achieve higher feed rates and prolonged tool life with this BL-style indexable tool holder. Featuring a 15-degree lead angle, it effectively thins the cutting chip and reduces radial pressure on your machine spindle, making it ideal for aggressive left-hand roughing. The 3/8-inch square shank and direct-screw locking mechanism ensure the carbide insert remains completely static, transferring cutting heat efficiently into the holder body.
