Abstract: A drill for producing a deep hole that does not produce a bend of the hole during cutting. A drill body is spirally provided with a pair of cutting edges. The cutting edges are spaced at about 180 degrees apart around a core of the drill and the edge line of a tip section of the cutting edges is depressed toward the core of the drill. When the outside dimension of the drill is 7.4 mm, an angle between the edge line and a line perpendicular to the core is 5 degrees and the core thickness (t) is 2.96 mm. Further, the drill is provided with a guide section for preventing bending during a cutting operation. The guide section is provided on a heel side on the same circumference as that on which the outer end section of the cutting edges passes.

Abstract: A drilling tool for producing drill holes includes a tip and a shaft arranged opposite the tip in a direction of a longitudinal axis of the drilling tool. The drilling tool has at least one geometrically defined cutting edge in the tip area, and has an expanded diameter trailing the tip in a longitudinal direction from the tip. The drilling tool has a first area with a first diameter that precedes the expanded diameter, and a second area with a second diameter, larger than the first diameter, that trails the expanded diameter. The drilling tool is distinguished in that the expanded diameter and/or the second area is/are embodied such that chips are produced in the area of the expanded diameter and/or in the second area when a workpiece is machined, chips consistent with those produced when a workpiece is machined with a geometrically undefined cutting edge.

Abstract: 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.

Abstract: A drill which includes a cylindrical main body and a shank contiguous to each other, and which is to be rotated about an axis of the cylindrical main body in a predetermined rotating direction, for machining a hole in a workpiece. The cylindrical main body has flutes which are formed in the cylindrical main body and extend from an axially distal end portion of the cylindrical main body toward the shank, so as to provide cutting edges in the axially distal end portion of the cylindrical main body. The cutting edges cooperate with each other to define a point angle which is not smaller than 170° and is smaller than 180°. Each of the cutting edges is substantially straight as seen in a direction perpendicular to the axis, or is curved such that each cutting edge is convexed as seen in the direction perpendicular to the axis.

Abstract: A cutting tool in the form of a drill bit or end-milling tool has an elongated body formed with at least one cutting edge defined by a flank of a flute running primarily along a rotation axis of the body and having leading and trailing flanks one of which is formed with wavelike and spaced projections and recesses. The depth of these grooves and, hence, the height of the projections increases toward the end cutting edge to break up chips.
