Designed for CNC Machines: Compatible with CNC machines that support through-spindle coolant, requiring a minimum of 300 psi for optimal performance.

Optimal Cutting and Chip Removal: Special coolant pipes and chip-guiding geometries ensure continuous flushing of the blade window and the blade, promoting superior chip removal and consistent cutting performance.

The BSF tool is a standout in precision engineering, particularly revered in the aerospace and automotive sectors for its single-operation back spotfacing and counterboring capabilities. This tool is engineered to eliminate the need to rotate the workpiece, streamlining production and enhancing efficiency.

The tools and blades are sold separately and they each have an OFFSET dimension. When combined they equal the effective counterbore diameter. For assistance, use our online Tool Selector.

Efficient Operation: Operates without the need to rotate the workpiece, utilizing a smoothly swinging blade that activates by spindle rotation and retracts through internal coolant or air pressure.

"By using the BSF tool we've gone from using 5 blades per part to only 1 blade. Our cycle time went from 62 minutes to 7 minutes and 45 seconds. And we're also estimating over $130,000 in savings."

Advanced Mechanics: Functions without an anti-rotation device, spindle direction change, or machine modifications, thanks to a simple swing mechanism enhanced by internal coolant pressure.

High Performance: Counterbores up to 2.3 times the diameter of the drill bit, featuring replaceable carbide-coated blades that extend tool life.

Crafted with precision for CNC machining, the BSF operates by harnessing centrifugal force upon spindle activation to expand its blade. Controlled by coolant pressure, a piston orchestrates the blade's smooth retraction into its housing. This distinctive design is finely tuned to deliver unmatched cutting precision, unwavering reliability, and seamless chip removal, setting new standards in machining excellence.
