Seco’s line of Square 6 shoulder milling cutters answers the need for added economy in square shoulder milling. This unique square shoulder milling cutter uses trigonal inserts with three cutting edges on each side – six total cutting edges – to lower the cost per cutting edge. Inserts lock into place via a strong center screw placed in the same direction as cutting forces, and wiper flats optimize surface finishes. The 90° setting angle ensures a true 90° square in one milling operation, eliminating the need for secondary operations and saving valuable production time and money. With two different cutter family sizes – Square 6 -04 and Square 6 -08 – each having multiple options in insert geometries and pitch, Square 6 offers superior performance in a wide range of materials, operations and machining conditions. Square 6 -08 is the larger insert version for higher depths in more demanding applications. The smallest diameter in this range is 1.5" up to 6.0". With a maximum depth of cut of 0.295", Square 6 -08 is the perfect choice for larger machines in applications requiring maximum security. Multiple grades and geometries are available to provide peak performance in a variety of workpiece materials. Like its larger counterparts, the Square 6 -04 effectively tackles a wide range of materials, operations and machining conditions, but from cutting diameters that range from 0.75" to 2.5", with a maximum cutting depth of 0.157". Square 6 -04 is a reliable, cost-effective, first-choice solution for all general machining requirements, including square shoulder milling, face milling, slotting, plunging and slotting by plunging.
