摘要： The present invention relates to a drill body for a drill having a rotational axis, comprising an inner pocket (20) formed adjacent to the rotational axis at a proximal end of the drill body and an outer pocket (20') formed further away from the rotational axis than the inner pocket at the proximal end of the drill body. Each of said pockets comprises a first wall (51, 61, 51", 61") facing the workpiece, a second wall (51', 61', 51"', 61"') substantially perpendicular to the first wall and disposed adjacent to the rotational axis of the drill body, and a bottom surface (71, 71'). Each of the first wall and the second wall comprise a respective flat lower side surface (61, 61', 61", 61 "', 61"") adjacent to the bottom surface and a respective curved upper surface (51, 51', 51", 51"', 51"") extending from the lower side surface. The first walls of the inner and outer pockets include identical surface shapes while the second walls of the inner and outer pockets include identical surface shapes.

摘要： The invention relates to a hard metal insert (2) for a rock drill (1), which is designed as a spiral drill operating without percussion, comprising a cylindrical drill head (11) and a working end (13) comprising the hard metal insert (2). The hard metal insert (2) comprises two main cutting edges (22) arranged radially opposite one another with respect to a drilling axis of rotation (d) and at an angle to each other to form a centring tip (21), which can each be assigned a peripheral conveying helix (14). In order to realise a drill hole in an easier and simpler manner and without risk of damage, in a workpiece made of rock, glass or similar, it is proposed that the main cutting edges (22) are formed asymmetrically to one another, wherein at least one of the main cutting edges (22) defines a tip (23) projecting in the drilling direction (b) over the radial course of same in a middle region spaced apart from the radial ends thereof.

摘要： A holesaw assembly (10) includes a holesaw (12) and a pilot bit (16). The holesaw includes a hollow cup (18) defining a center axis. The cup has a round base perpendicular to the center axis and a peripheral wall coupled to and extending axially forward of the base to a peripheral edge at a free end of the wall. The pilot bit (16) is received in the holesaw (12) along the center axis. The pilot bit (16) has a shaft received in the base, a cutting head coupled to a front end of the shaft, and an at least partially threaded tip (82) coupled to a front end of the cutting head. The holesaw (12) is free of any radial cutting elements disposed inside the cup (18) between the drill bit and the peripheral wall of the cup (18).

摘要： A drill according to an embodiment of the present invention has a pair of main cutting edges positioned at a front end of a drill body, a pair of first chisel edges each extending from the pair of main cutting edges toward a rotation axis, and a second chisel edge positioned between the pair of first chisel edges and intersecting with the rotation axis of the drill body. When viewing a locus of rotation of the pair of first chisel edges and a locus of rotation of the second chisel edge in a cross section taken so as to include the rotation axis, the respective locus of rotation of the pair of first chisel edges have a rectilinear shape, and respective imaginary straight lines obtained by extending the locus of rotation of the pair of first chisel edges toward the rotation axis are positioned further to a rear end side of the drill body than the locus of rotation of the second chisel edge.
