Corner radius milling cutter EPDRF-TH

Flute shape provides both rigidity and cutting performance No chattering even during high-speed machining Machined surface roughness of bottom is also good. Like bail end mills. corner R accuracy is kept to within ±0.005/im relative to the tool's central axis, achieving an unprecedented high corner R accuracy. This enables high-accuracy finish machining to be performed, something which has been difficult to do with previous corner radius end mills. In addition, the smooth cutting face provides a corner R bit with no joints from the outer flûte to the bottom flûte. By using a flûte shape with both good chip removal characteristics and rigidity, high-efficient deep machining can be performed. Chip jamming is prevented and chattering vibrations are suppressed so that a good machined surface can be achieved. By designing the bottom blade to hâve a slight wiper blade (by providing a slight angle), good finish cutting of the bottom surface is possible even for high-efficient cutting. Particularly for tools with long below-the-neck lengths, for which vibrations are likely to occur, good surface roughness can be achieved for bottom finish machining, such as for deep rib
