摘要： A coolant-hole equipped drill includes a drill main body, a cutting edge portion which has a tip flank, a chip discharging groove provided with a front groove wall surface and a rear groove wall surface, a cutting edge formed at a ridge line portion where the front groove wall surface and the tip flank intersect with each other, a land portion formed between the chip discharging grooves adjacent to each other in the rotating direction, and a coolant hole drilled at the land portion and opened at the tip flank. The coolant hole includes a front hole wall surface, a rear hole wall surface, and an outer-circumference hole wall surface.

摘要： A guide portion prevents the drilling hole from curving due to a skipping rope phenomenon, and also prevents the inner wall face of the drilling hole from being damaged, so that its surface roughness can be improved.Chip evacuating flutes 4 are formed in the periphery of a drill body 1 which has a stick shape and is rotatable on its axis O, from its front flank 3 toward the rear side.Cutting edges 2A are formed along ridge lines where the front flanks 3 intersect with wall faces 4A which are in the chip evacuating flutes 4 and face in a drill rotational direction T.A cutting edge section 2, where the cutting edges 2A are formed, is provided in the front side of the drill body 1. A cutting edge section 2 has an external diameter which is smaller toward the rear side in the axis O direction than the external diameter D at the cutting edges 2A.A guide portion 6 has a maximum external diameter part 6A at the front periphery side, and is provided to the rear side of the cutting edge section 2. An external diameter at the maximum external diameter part 6A is larger than the external diameter at the rear of the cutting edge section 2, and is smaller than or equal to the external diameter D at the cutting edges 2A.The maximum external diameter part 6A of the guide portion 6 shows a smooth convex curve shape in a rotatory figure obtained by rotating it on the axis O.
摘要翻译：引导部分防止钻孔由于跳绳现象而弯曲，并且还防止钻孔的内壁面被损坏，从而可以提高其表面粗糙度。切屑排出凹槽4形成在钻头主体1的周边，其具有棒状并且可以从其前侧3向后侧在其轴线O上旋转。切削刃2A沿着脊线形成，其中前侧面3与位于排屑槽4中并面向钻头旋转方向T的壁面4A相交。切削刃部分2形成切削刃2A，设置在钻头主体1的前侧。切削刃部分2具有比在切削刃2A处的外径D更靠轴O方向的后侧的外径。引导部6在前周侧具有最大外径部6A，并且设置在切削刃部2的后侧。最大外径部6A的外径大于后方的外径，并且在切削刃2A处小于或等于外径D. 引导部分6的最大外径部分6A在通过在轴线O上旋转获得的旋转图中显示平滑的凸曲线形状。

摘要： A drill comprises a drill body that is rotatable on an axis. Chip evacuating flutes, which are open on front flanks of the drill body and are extended rearwards, are formed in a periphery of the drill body on its front side. Cutting edges are formed along ridge lines where the front flanks intersect with wall surfaces of the chip evacuating flutes facing a drill rotating direction. At least first and second front flanks are formed on the front flanks in order of their locations in the drill rotating direction from its leading side to its trailing side. A clearance angle of the second front flank is greater than that of the first front flank. Intersection lines of the first and second front flanks cross the cutting edges.
