Disc Milling Inserts and Cutter Bodies ( 335.14, 335.16, & 335.25)

Sept. 6, 2017
Seco Tools, LLC have met customer demands with cutters that cut materials in widths ranging from 0.39 to 0.82 in.

Disc milling inserts and cutter bodies 335.14 small-diameter exchangeable head system, 335.16 cutters for T-slot operations, and cassette versions of its 335.25 cutters that incorporate round inserts.


Using small-diameter exchangeable carbide heads, the 335.14 offers a versatile, precise cutting profile that easily tackles any type of material. These cutters are ideal for groove milling, circlip grooves, full radius profiles, threading profiles, and chamfering. Reliable exchangeable head systems control machining costs and the 335.14 product line comes in a wide variety of cylindrical and integrated collet chuck shanks in diameters from 0.38 to 1.37 in. (9.7 to 34.7 mm) that cut widths from 0.03 to 0.207 in. (0.74 to 5.26 mm).


The stable 335.16 cutters incorporate 4-edged inserts to economically perform demanding T-slot operations. Modern insert geometries reduce machining forces and noise for optimum tool life. Centralized cooling channels effectively remove chips and provide excellent surface finishes and finished part quality. Cutters come in diameters from 0.97 to 1.844 in. (25 to 50 mm) based on standardized T-slot dimensions. The expansive selection of insert geometries and grades cut many materials in widths ranging from 0.39 to 0.82 in. (11 to 21 mm).


The expanded line of 335.25 disc mill cutters now includes new cassettes for 0.63 and 0.79 in. (16 and 20 mm) round insert diameters. These cutters perform well in various full side, face or half side and face operations for applications involving corner radii. The exchangeable cassettes ensure long, reliable cutter performance, while the large choice of insert geometries and grades provide freer cutting operations and increase cost-efficiency in any type of material. Cutter diameters for these sizes range from 4 to 12 in. (100 to 315 mm).
