[Features]
·Demonstrates high performance in processing general steel, SUS304, and heat-treated steel (up to 50 HRC)
·By leaving the round land width (the width of the cylindrical part without relief angle on the peripheral flute), it is possible to obtain an effect similar to that of a reamer and improve the surface roughness of the machined surface
·The end cutting edge is nearly flat, making it ideal for finishing counterbore holes.
·By adopting 3-flute shape, chattering that tends to occur in drilling and counterboring is suppressed
·Optimal for machining in low to medium rotation range due to the general-purpose 30° helix angle
·It has coating with high oxidation resistance and high hardness, and achieves a long service lifespan. Effective in high-speed machining and dry machining as coating properties

● It achieves an effect similar to a reamer by leaving a round land width (the width of the cylindrical part of the peripheral blade without neck relief), increasing the surface machining accuracy.
● The bottom blade is nearly flat, ideal for finishing countersunk holes.
● It has a 3-flute blade shape that suppresses the chatter that tends to result from hole drilling and countersunk hole machining.
