Widia Hanita 4976 endmills designed to boost productivity on a variety of materials

Widia Hanita 4976 solid carbide endmills are manufactured from a high quality micro grain carbide and AlTiN coated. Capable of side milling, slotting and ramping processes, they are available with either three or four flutes to offer a solution for machining a wide range of materials and applications. ITC recommends that end users utilise robust and rigid machine tools capable of meeting the optimal speed and feed range of the cutters. With a diameter range that includes 4, 5, 6, 8, 10, 12, 16 and 20 mm – and a maximum length of cut from 8 to 38 mm – the 4976 Series has been developed with optimal geometries and proportionate dimensions for rigidity and high material removal rates. Overall cutter lengths are from 57 to 104 mm depending upon diameter selected. The endmills also incorporate a flat shallow pitch ripper form to promote the elimination of chatter and vibration by improving cutting efficiency particularly on difficult to machine materials. The optimised 30º polished flute geometry removes swarf efficiently from the cutting zone and eliminates any potential for re-cutting of the chips and the inevitable cutting edge damage that is an issue for alternate milling cutters. A 0.25 mm chamfer on diameters from 4 to 10 mm and a 0.35 mm chamfer on endmills from 12 to 20 mm diameter ensure that chipping of the cutting edge is eliminated. The Widia Hanita 4976 endmills are featured in ITC's latest Widia Slimline catalogue.
