摘要： A method for producing cutting tools incorporated in the present invention is carried out as follows: a shank portion and a drill portion are formed separately such that the inner diameter of a hole made in the shank portion is slightly smaller than the outer diameter of the drill portion. The rear of the drill portion is forcibly inserted into the hole of the shank portion at normal temperature which is room temperature. The diameter of the inner wall of the hole is thereby enlarged, resulting in a tight fitting. After the insertion of the drill portion in the shank portion, the drill portion may be ground to form a drill edge. Before the insertion of the drill portion in the shank portion, the shank portion may be quenched under vacuum or the like, or the surface of the shank portion may be hardened by nitriding.

摘要： An improved drill bit for high speed, small diameter drilling of printed circuit boards uses flute/land ratio tapering in combination with the appropriate web thickness and point, cutting or flute angles to obtain high quality, accurately positioned holes. In one embodiment, the web thickness at the tip is 15% of the drill diameter, the flute/land ratio is 2.0, the tip angle is 130.degree., the second cutting angle is 20.degree., the third cutting angle is 30.degree., the flute angle is 32.degree., the relief groove depth is 0.001", body length is 0.256" and the distance between the body end and the flute end is 0.01". Such a bit is used in connection with an air jet cooling/cleaning system and a step feed drilling method wherein the first step is between four-six times drill diameter, the second step is between two-three times the drill diameter, and the third step and subsequent steps are between 1.5-2.5 times the drill diameter.

摘要： An apparatus for adjusting the positioning of a locating ring upon a drill bit. The apparatus comprises a housing having a drill seat attached thereto for slidably receiving the shank portion of the drill bit. The apparatus further comprises an adjustment mechanism which is attached to the housing for positioning the cutting tip of the drill bit at a desired separation distance from the drill seat. Also included is a reciprocal ram assembly attached to the housing for selectively bumping the locating ring into abutting contact with the drill seat subsequent to the insertion of the shank portion into the drill seat and the positioning of the cutting tip at the selected distance relative the drill seat.

摘要： Disclosed is a very small sized rotating and cutting tool comprising a rotating and cutting part such as drill bit and a shank which is a separate solid body having a through aperture permitting insertion of the rotating and cutting part into the through aperture and removal of the rotating and cutting part from the through aperture when it has been worn or broken. With this arrangement the worn or broken rotating and cutting part can be easily removed from the shank simply by pushing the rotating and cutting part out of the through aperture of the shank, and the shank can be reused. Also, advantageously the lathing of a relatively large cylinder into a "large-and-small cylindrical object" as is carried out in making a conventional miniature drill, is not required. For these reasons miniature rotating-and-cutting tools can be manufactured and marketed at reduced price.

摘要： A method for lubricating a material-working tool comprises depositing a material film by high energy level vacuum plating onto the tool for providing a thin mechanically insulating film having a low shear stress value. The material film has a hardness which is less than the hardness of the tool which it overlies.

摘要： The flute terminus or carry out of a microdrill is located spaced from cross-sectional changes of the drill and away from such areas of stress concentration and permits a slight flexing of the drill to compensate for standard production environment in efficiencies such as spindle runout, nonperpendicularity of drill to workpiece and workpiece material which is not homogeneous.
