Miranda Ball Nose End Mills, 2 & 4 Flute, AlTiN, 1mm to 20mm

Mould cavities, die contours, freeform surfaces: Miranda ball nose end mills cover 3D work from 1.00mm to 20.00mm diameter in both 2-flute and 4-flute versions, Standard and Long lengths. The working split: rough with 2-flute for chip clearance in deep cavities, finish with 4-flute for surface quality, often in the same setup. Step-over decides your finish; at 3-5% of ball diameter, scallop height drops under a micron for near-mirror mould surfaces. AlTiN coating copes with the speed swing across the ball, from near zero at the tip to full speed at the periphery, and DIN 6535HA h10 shanks fit standard holders. Mould makers and die shops across Noida-NCR buy these as matched sets. Stocked at Sector 9, Noida; WhatsApp for price.

Frequently Asked Questions: Ball Nose End Mills

For a mirror-like finish on moulds, use a step-over of 3-5% of the ball diameter. For general finishing, 8-10% works well. For roughing, you can go up to 25-30% step-over. For example, with a 10mm ball nose end mill, a 0.5mm step-over (5%) gives an excellent surface finish with scallop height under 1 micron. The finer the step-over, the smoother the surface, but machining time increases significantly.
