Seco Tools has improved the Perfomax indexable insert drills, including a changed helix for improved productivity and chip evacuation; a refined core for improved strength and stability; and an improved drill point to increase tool life and achieve better tolerance, the company says.
The drills feature an optimized chip flute design, a low friction-coated drill body and strong insets. This allows users to increase productivity and reduce total cost by boosting speeds and feeds while avoiding common problems of deflection, poor tool life and quality, even with long lengths and deep-hole drilling applications. These drills use square inserts to provide a strong, 90-degree corner and the economy of four cutting edges.
Perfomax is available in a range of user-friendly drill diameters (0.59" to 3.50") and lengths of as much as 5 × diameter in certain sizes. The tool uses different inserts in periphery and center insert pockets to provide the balance of cutting forces and the highest cutting data possible.
