CAT (V-Flange) END MILL HOLDERS All toolholders are: - Precision ground for solid spindle contact - 100% inspected for quality control - Value-priced to control your costs On The Fast Track: For optimum performance on today’s high speed machining centers, balanced toolholders are recommended by most machine tool spindle manufacturers. All Centaur Toolholders are balanced for 16,000 R.P.M., with AT3 or better accuracy on the taper fit and finish — one third of the ANSI specification requirement, and concentric to .0002 TIR or better. All Centaur Toolholders have fully ground flanges and V-grooves to ensure smooth, accurate handling in automatic tool changers and reduced vibration at high R.P.M. Centaur’s commitment to toolholder accuracy provides the best spindle to cutting tool union in the industry and will provide these benefits: - Extended tool life = More time in the cut, less downtime for tool replacement. - Increased feed rates at higher R.P.M. = Less vibration and better concentricity allow the cutting tool to perform as designed. - Increased workpiece accuracy = Lower costs for machine adjustments and inspection. - Improved workpiece surface finish = Less secondary finishing. - Centaur Toolholders = finished products with better dimensional accuracy at a lower cost...
