Now available from Horn is a new generation of milling cutters for machining at high feed rates. The DAH82 and DAH84 milling systems feature a precision-sintered indexable insert with eight cutting edges for cost-effective metal cutting. Despite its negative mounting position, the positive cutting geometry ensures good chip removal combined with a smooth, soft cut. Furthermore, the large radius of the insert’s main cutting edge ensures even distribution of the cutting forces, extending tool life.

Horn offers the inserts in the SA4B substrate, which is suitable for universal use on various materials. Maximum cutting depths are 1.0 mm for the DAH82 and 1.5 mm for the DAH84.
The DAH82 variant is available as an end mill and as a screw-in milling cutter in the following diameters: 20 mm (z = 2), 25 mm (z = 3), 32 mm (z = 4), 35 mm (z = 4) and 40 mm (z = 5), where z denotes the number of inserts. As an arbour milling cutter, it is available in diameters of 40 mm (z = 5), 42 mm (z = 5) and 50 mm (z = 6).

For diameters in excess of 50 mm, the larger DAH84 indexable insert is used. It can be supplied as an arbour milling cutter in the following standard diameters: 50 mm (z = 4), 52 mm (z = 4), 63 mm (z = 5), 66 mm (z = 5), 80 mm (z = 6), 85 mm (z = 6), 100 mm (z = 7) and 125 mm (z = 8). All tool bodies receive a special surface treatment of high strength and hardness, providing long-term protection against abrasive wear from chips.

Seco Tools is offering a new family of versatile, highly productive solid-carbide end mills: the JSE510 series. Redesigned to offer more rigidity, chip control and tool life, the company says the new milling cutters achieve the lowest possible costs per metre of machined steel, stainless steel, cast iron, titanium and some aluminiums. The cutters provide high process reliability across a broad application range.

JSE510 cutters offer higher versatility in comparison with the previous version of this product range, not just for general engineering, contract manufacturers and job shops, but those specifically serving the aerospace, medical and automotive industries. Seco’s design for the JSE510 stands up to tough milling applications with a versatile carbide grade, advanced polished SIRA coatings and a strong, sharp cutting edge. To extend tool life further, the tools offer a vibration-damping variable pitch design and an optimised helix.

Seco’s JSE510 family includes 216 tools in four geometries, with two length variants in the three and four-flute version: normal (LV2) and long (LV3). The two-flute JSE512 handles the large chips produced in helical interpolation or peck drilling, keyways and slotting applications, while the three-flute JSE513 offers universal milling performance for ramping, full slotting and side milling. The four-flute JSE514 is for side milling and slotting, as well as dynamic milling. Finally, the ball-nose end-mill geometry of the JSB512 offers the versatility required for finishing operations.

“These cutters offer productivity in less stable machining conditions or when pushed hard to balance productivity and tool life costs,” says Rob Mulders, solid end mills global product manager. “This versatility makes the JSE510 series particularly useful when shops face increased tooling costs because of a greater variety of applications and materials.”
