Epoch Deep Radius F changes common sense about corner radius end mills! Features of EPDRF-TH Flute shape provides both rigidity and cutting performance. Chattering is not likely even during high-speed cutting. Machined surface roughness of bottom is also good. Carbon steel Alloy steel Stainless steel Pre-hardened Tool steel steel Like ball end mills, corner radius accuracy is kept to within ±0.005mm relative to the tool's central axis, achieving an unprecedented high corner radius accuracy. This enables high-accuracy finish machining to be performed, something which has been difficult to do...

^Comparison based on the individual characteristics of radius end mills and ball end mills O Large step widths can be taken for flat machining. (Fig. 1) 2 Since peripheral speed is increased at the cutting point, machining efficiency can be increased on machines for which rotation speed cannot be increased. e Because chip removal characteristics are high at the cutting point, chip jamming is reduced. o For small-diameter long-neck end mills in particular, cutting resistance is reduced, enabling stable machining compared to ball end mills. (Fig. 2) 5 When using tools with R size matching the...

Work material The indicated standard cutting depth is a reference value for Group 2 work materials. For materials in other groups, the cutting depth should be adjusted using the reference ratio shown in the above table. The above conditions are reference conditions for finish machining. For rough machining, it is possible to increase the feed rate by around 30%. ®Use the appropriate coolant for the work material and machining shape. ©These Recommended Cutting Conditions indicate only the rule of a thumb for the cutting conditions. In actual machining, the condition should be adjusted...

Cautions regarding handling (1) When removing the tool from its case (packaging), be careful that the tool does not pop out or is dropped. Be particularly careful regarding contact with the tool flutes. (2) When handling tools with sharp cutting flutes, be careful not to touch the cutting flutes directly with your bare hands. 2. Cautions regarding mounting (1) Before use, check the outside appearance of the tool for...
