Extended flutes for ball nose range

In addition to other machining fields, the progressive work of the cutting tool maker’s creative R&D department has enabled the company to remain constantly at the forefront of milling cutting tool developments.

The latest company innovation is the expansion of Iscar’s ‘DropMill 3 Flute Ball Nose’ (BLPK) range by the addition of extended flute endmills. The new, extended flute ball-nose endmills carry tangent straight edge inserts that enables machining to be carried out beyond the round edge of the cutters. The extended flute ball-nose endmills are designed for both roughing and semi-finishing operations. In addition to use in general engineering, they are particularly useful for cavity profiling and shouldering in the die and mould industry.

The tools feature three effective flutes, centre cutting and coolant holes that are directed to the cutting edges. The application of a Hard Touch coating assists smooth chip flow; it provides protection from corrosion and also delivers excellent wear resistance.

The use of Iscar’s 3 Flute Ball Nose range enables machining at higher depths of cut than the cutter’s radius. In addition to allowing a wider application range, increased table speeds and depths of cut provide increased productivity when compared to the current BCM DropMill cutters that carry BCR inserts. Also, reduced cutting forces lead to improved stability and less power consumption.

Applications include the rough and semi-finish milling of complex surfaces, especially those with steep and perpendicular profiles, including up and down ramping. The advanced new tools are available in 32, 40 and 50mm diameters, complementing the company’s existing DropMill 3 Flute ball-nose line.
