    摘要： A drill bit sharpening apparatus designed to sharpen the points of bits having differing diameters and differing point angles. The apparatus accommodates bits having differing point angles by providing a bit cradling member that has a plurality of mounting apertures formed therein wherein the respective positions of such apertures are predetermined to position the bit to be sharpened in proper angular relation to the grinding means, such aperture positions being mathematically determined. Bits of differing diameters are accommodated by a mechanism that positions the bit cradling member and hence the bit to be sharpened in the proper spaced relation to such grinding medium, said positioning also being mathematically determined. A different gauge member is provided for each differing point angle, and a plurality of algorhythm-derived points are marked on each gauge, which points represent the respective settings of the apparatus as between bits of differing diameters.

    摘要： TO THIN THE WEB OF A DRILL, THE DRILL IS ORBITED SO THAT, ONCE DURING EACH ORBIT, ITS WEB CONTACTS A ROTATING GRINDING WHEEL THAT IS POSITIONED APPROXIMATELY AT A 25DEGREE ANGLE FROM THE HORIZONTAL. THE GRINDING WHEEL ABRADES THE WEBS TO FORM A RECESS HAVING A RADIUS DETERMINED BY THE RADIUS OF THE ORBIT. THE RADIUS OF THE ORBIT MAY BE ADJUSTED WHILE THE DRILL IS ORBITING.

    摘要： A holder for sharpening twist drills wherein the drill rests between sets of rollers mounted on a pair of parallel shafts. The shafts form part of a frame which pivots a limited amount about an axis perpendicular to the axis of the drill. A clamp is secured to the drill, and is provided with diametrically disposed shafts either one of which is insertable between a pair of fixed rods underlying the rollers which cause the drill to turn on its axis as the frame is moved arcuately. An adjustable stop controls the axial position of the drill. A modification involves the use of a slotted V-guide.
