    • PROBLEM TO BE SOLVED: To smoothly discharge chips of a long bottom blade, by effectively restraining flank wear of the long bottom blade on the tip of an end mill body.SOLUTION: A bottom blade 9 is formed in a crossing ridgeline part between a gash 7 and a tip flank 8 on the tip of a plurality of chip discharge grooves 4 formed in the end mill body 1, and among the bottom blades 9, at least one sheet is formed as the long bottom blade 9A extending longer to the inner peripheral side than the other bottom bladeS 9B and 9C, and a coolant hole 10 is formed between the mutual chip discharge grooves 4 in the end mill body 1, and a coolant hole 10A between the chip discharge groove 4A of the gash 7A forming the long bottom blade 9A and the chip discharge groove 4C on the rear side in its end mill rotating direction T, is opened on a tip flank 8A of the long bottom blade 9A, and a coolant hole 10B between the chip discharge groove 4A of the gash 7 of the long bottom blade 9A and the chip discharge groove 4B on the side in its end mill rotating direction T, is opened in the gash 7A of the long bottom blade 9A.
    • 要解决的问题:通过有效地限制端铣刀体的顶端上的长底刀片的侧面磨损,平稳地排出长底刀片的切屑。解决方案:底刀片9形成在间隙之间的交叉棱线部分 7和在端铣刀体1中形成的多个切屑排出槽4的前端上的刀片侧面8,在底部刀片9之间形成有至少一个片材,作为延伸到内周的长底部刀片9A 并且在端铣刀体1中的相互排屑槽4之间形成有冷却剂孔10,并且在形成长底部的间隙7A的切屑排出槽4A之间形成冷却剂孔10A 刀片9A和位于其立铣刀旋转方向T的后侧的排屑槽4C在长底刀片9A的顶端侧面8A上打开,并且在槽口7的排屑槽4A之间的冷却剂孔10B 长底刀片9A和芯片盘 在其端铣刀旋转方向T侧的倾斜槽4B在长底刀片9A的齿槽7A中打开。
