Seco Tools announces developments to its 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. Also available are a coated lathe drill (SD572) and coated large-diameter drill (SD542) that incorporates a helix flute and a range of 2.25" to 3.5".
According to the company, drills featuring an optimized chip flute design, low-friction coated drill body and strong insets offer excellent productivity. This is said to allow 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. Unlike other indexable insert drills, these use square inserts to provide a 90-degree corner and the economy of four cutting edges, the company says.
The indexable insert drills are available in a range of drill diameters from 0.59" to 3.50" and lengths to 5 × D in certain sizes. The inserts are also available in a range of geometries.
