HSB-S Unimax ballnose, small, short-shank end-mills from Union Tool for material up to 70 HRc

Specifically aimed at the toolmaking industry, Rainford Precision has introduced the new series of HSB-S Unimax ballnose, small, short-shank end-mills from Union Tool for material up to 70 HRc.

The two-flute end-mills are ground to an H4 tolerance of 0/-0.004 mm and are designed for use with precision machine tools and toolholders such as shrink-fit units. Another key feature is the ±0.003 mm tolerance of the ballnose radius, which improves surface finish when machining.

Featuring HardMax coating technology and negative rake angle geometry, HSB-S Unimax is offered with a ball nose radius of 0.1, 0.15, 0.2, 0.3, 0.4, 0.5, 0.75, 1, 1.5 and 2 mm, with a length of cut from 0.2 to 4 mm and an overall length of from 35 to 40 mm to minimise tool protrusion and maximise rigidity.

A long-necked with a ballnose radius from 0.1 to 3 mm has a maximum clearance length of 20 mm and an overall length from 35 to 50 mm, depending upon the selected tool diameter.
