摘要： A drill bit (100) for forming a round hole in a workpiece, includes a cylindrical shank (102) having a longitudinally extending fluted portion (104) with opposed first (106) and second (108) ends, and defining a longitudinal axis (A) about which the shank is rotatable. The fluted portion includes opposed helical flutes (110) formed in the cylindrical surface of the fluted portion of the shank and extending longitudinally along and between the first and second ends of the fluted portion. The helical flutes each define a concave surface (112) intersecting with the cylindrical surface of the shank to form opposed flute edges (114). The first end of the fluted portion includes a cutting tip (116) intersecting the helical flutes, wherein at least one of the flute edges has a concave cross-section extending from the second end toward the first end of the fluted portion.

摘要： A method of manufacturing endodontic files (10) involves a chemical milling process to yield endodontic files having a desired degree of sharpness. The chemical milling process forms a tapered portion (18) of the endodontic file (10). The process involves the steps of (a) forming helical cutting edges in the cutting portion of the metallic rod (12) and (b) chemically milling the cutting portion (18) of the rod (12) so as to at least sharpen and optionally taper the cutting portion (18). The rod (12) may be formed of any desirable metallic material, for example stainless steel or a nickel titanium alloy. The cutting edges may be formed by torsioning, cutting, grinding, machining, laser micromachining, or grit blasting. Chemical milling can also remove cracks or microfissures, yielding more contiguous cutting edges that better resist cracking or breakage.

摘要： The invention relates to a tool blank (1) for a drill, the tool blank being substantially cylindrical and having a front end (2), a rear end (3) and a central longitudinal axis (L) extending therebetween. The tool blank comprises at least one vein (4) of a superhard material formed at the front end, wherein the vein has a depth (D) in the axial direction and comprises a bottom surface (12), a first side surface (13) and a second side surface (14). Each vein has an extension in an inward direction from the periphery of the tool blank. For each vein, the first side surface forms an inclination angle (α) with respect to the longitudinal axis that varies with the radial distance to the longitudinal axis of the tool blank over at least a major part of the extension of the vein. The inclination angle substantially corresponds to a desired axial rake angle of a drill (5) to be manufactured from the tool blank. The invention also relates to a drill manufactured from such tool blank, and a method for manufacturing a drill.

摘要： A cutting tool body (109) is disclosed, comprising a first member (101) and a second member (102), both having a substantially cylindrical shape, and arranged such that a tool body central axis (T) coincides with a central axis (LI, L2) of each of the first and the second members. The first member has a tool characteristic of a first magnitude, and the second member has the tool characteristic of a second magnitude, different from the first magnitude. The cutting tool body comprises a transition member (103) arranged between the first and second members and connected at a first end to the first member and at a second end to the second member. The tool characteristic in the transition member is of the first magnitude at the first end, and of the second magnitude at the second end. The transition member comprises a transition region between the first and the second ends in which the tool characteristic transforms from the first magnitude to the second magnitude, furthermore, a method for forming a cutting body is disclosed.
