Seco Tools LLC, Troy, Mich., introduced two new insert sizes to its family of 335.25 disc milling cutters, a line that is said to provide manufacturers with high flexibility and productivity. With the additions of XNHQ inserts in 9mm and 12mm sizes, the cutter now offers a range of cutting widths from 0.531" to 1.26" (13mm to 32mm) for an even greater variety of applications.

The 335.25 disc milling cutter performs slotting, back facing, helical and circular interpolation, and plunging operations. Incorporating a unique cutter design and insert geometry with four cutting edges, the 335.25 cutter reportedly reduces cutting forces and optimizes chip flow to ensure reliable and productive machining. The line features both fixed-pocket and adjustable-width versions to accommodate all production environments.

Available in diameters ranging from 4" to 12", the 335.25 line includes 0.75" and 1" cutting widths for the fixed-pocket version, and from 0.531" to 1.26" cutting widths for the adjustable-pocket version. Inserts are offered in four sizes with corner radii from 0.016" to 0.236" (0.4mm to 6.0mm). Additionally, the range of insert grades available allows the 335.25 to be applied to all material types, and each insert reportedly reduces costs by offering four cutting edges, two left hand and two right hand.
