Finally, the answer you've been looking for is here... 1 Sharp cutting edge 2 New flute geometry 3 Special margin shape 4 New coolant hole shape

WDO-SUS Drill for Stainless Steels & Various Materials OSG’s next generation of carbide drills is an almighty one. Focused on the reduction of thrust and aimed at machining Stainless Steel, WDO-SUS-3D/5D is the perfect drill to use for your machine. The ute design produces optimal chip shape, thereby realizing smooth chip evacutation. The margin form is designed to realize low resistance and low cutting temperature. Common machining problems associated with these materials : • Work hardening tendency • Elongation of chips • Low thermal conductivity • Welding on cutting tool

Key features & Benefits WDO-SUS-3D/5D 1 Solution for work hardening - Sharp cutting edge Reduces work hardening, which leads to longer tool life during tapping and reaming Tool 1.5MPa Water Soluble Internal Work Material Feed Rate Horizontal Machining Center Vickers Hardness Distance from the wall surface of the hole 2 Solution for elongation of chips - New flute geometry Enables the creation of compact cutting chips

Key features & Benefits WDO-SUS-3D/5D 3 Solution for high machining heat - Special margin shape Reduces friction and heat generation Margin surface Front view Side view 4 Solution for high machining heat - New coolant hole shape Improves coolant ow, chip evacuation and cutting heat generation (m/s) Coolant flow velocity 25.0 Analysis of coolant flow with spindle speed of 2,200min-1 5 Solution for welding - heatWXL® coating High adhesion strength, which minimizes the possibility of chipping
