Cutting Tools Small-Diameter Cutting Tools Seco Tools offers several small-diameter cutting tools designed to increase productivity and provide longer tool life for mold machining. Available in diameters from 0.75" to 2.5" and with a maximum cutting depth of 0.157", Square 6-04 shoulder milling cutters are suited for general machining operations on small and medium milling machines, including square shoulder milling, face milling, slotting, plunging and slotting by plunging. The High Feed 2 high-feed milling cutter provides high feed rates at small depths of cut for applications such as pocketing, ramping, helical interpolation, facing, contouring, slotting and plunging. Cutter diameters range from 0.625" to 1.25". Available in diameters from 1" to 5", the Double Octomill-05 face milling cutter is suited for small machines and applications requiring maximum depths of cut of 0.118". This cutter uses inserts that provide 16 numbered cutting edges to minimize cost per edge and per part. Insert pockets feature 8-degree negative angles for using double-sided inserts, while inserts use positive rake angles to minimize power consumption.

The uncoated grades deliver an effective solution in high-speed to general purpose turning. The BN1000 supplies users with excellent tool life in continuous cutting to light-interrupted cutting, the company reports. High speed finishing of die steels and bearings is made possible through improved fracture and wear resistance. The BN1000 sets the bar for high-speed uncoated turning. The BN2000 provides a general purpose grade for the machining of hardened steel. When machining bearings or die steels, the BN2000 provides stable tool life on continuous cutting to medium interrupted cutting. The uncoated series derives from a newly developed high-purity ceramic binding. This advanced binding increases heat resistance while strengthening the tolerated cutting force. The BN1000 and BN2000 are available in single corner and multi-corner type inserts.

DiamondPlus end mills feature a combination of micro and non-crystalline coatings and are engineered specifically for demanding applications such as machining graphite, green ceramics or composite materials such as MMC or CFRP. Stabilizer end mills feature specially engineered, variable-flute geometries designed to significantly reduce distorting harmonics and chatter. This design enables greater depths-of-cut, faster speeds, heavier feeds and better surface finish, resulting in increased tool life and productivity, the company says. Stabilizer end mills feature Microshield TiAlN coatings and are available in a range of configurations and sizes.
