Stainless steel JS4045 GX2140 Carbon steel Alloy steel Pre-hardened steel Hardened steel 30̃45HRC Applications Cast iron Design Registration No.1579894 Design Registration No.1579895 Reduces uncut remnants on work pieces The cutting edge shape was reviewed for TD4N so that uncut remnants are reduced. This enables the load on the next process to be reduced by up to 40%compared to conventional products. ・Since it is difficult to create tool shape definitions in CAM for the complicated cutting edge shapes of high-feed tools, in many cases the tools are used with the definition for a simple R...

Large tip diameter for excellent handling ・Compared to conventional high-feed tools, TD4N has a large tip diameter, which suppresses the generation of uncut remnants which easily occur on the bottom surface of machined areas. In addition, since the cutting width (ae) can be set to a large value, this is also effective for improving machining efficiency. Photograph of machined surface at corner (viewed from above) Tip diameter （Flat area） Uncut remnants Tool diameter Excellent chip discharge characteristics ・Reduces the occurrence of sudden problems due to jamming of cutting chips.

* Red indicates primary recommended insert grade. Cutting depth per rotation should be set to ap = 1 mm or less. [Note] V It is recommended that the tool be used while performing sufficient chip removal and checking that there are no abnormal vibrations. © The ramp angle 9 should be set within the ranges listed above. Use at ramp angles of 0.5° or less is recommended. © For hole diameters outside the ranges listed above, a pilot hole should be drilled before milling. Points requiring care when creating the machining program • In CAM, define the tool shape as an R2.0 radius shape. • Use with...
