A tool mounting block for a cutting machine has a forward surface and an aperture in the forward surface for receiving the cylindrical mounting portion of a tool. The forward surface has a plurality of radial grooves therein extending to the outer surface of the tool mounting block. To extend the useful life of the mounting block, an annular insert is fitted around the aperture such that the forward surface of the insert provides a bearing surface to facilitate rotation of the tool within the mounting block.

Improvements in bits, bit holders and bit blocks used in road resurfacing equipment and mining and trenching equipment provide for improved rotatable bit holders in the bit block, ease of removability of bits from bit holders and for predetermined points of desired failure of any member of the combination if the bit should encounter a hard discontinuity while performing its work.

An improved bit holder with its mating bit block utilizes a slight taper in the bit block bore, and a tapered shank on the bit holder that includes a second larger diameter tapered distal segment that combines with an axially oriented slot through the side wall of the bit holder shank to allow a substantially larger interference fit between the distal tapered shank segment and the bit block bore than previously know. When inserting the bit holder in the bit block bore, the distal first tapered segment resiliently collapses to allow insertion of that segment into the bit block bore. A second shank tapered portion axially inwardly of the first distal tapered portion and separated therefrom by a shoulder provides a space between the bit block bore and the second tapered shank portion until the upper â to  inch of the second tapered shank portion meets and again forms an interference fit with the bit block bore at a portion of the shank above a termination of the slot therethrough. The dual tapered shank allows the insertion of the bit holder in the bit block with an interference fit that provides a secure mounting of the bit holder in the bit block. Since there is no fastener to maintain the bit holder in the bit block, it may be removed from the bit block by driving the base of the bit holder out of the bit block.

A tubular part is brazed into coaxial relationship with the bore in a metal body part having a counterbore for receiving the tubular part. In a first embodiment a tubular sleeve is fitted within the bores of the metal body and the tubular part. The parts are then heated and vibrated while the braze material is melted. In a second embodiment a frustoconical plug is inserted into the coaxial bores of the parts and the parts are again heated and vibrated. The parts are allowed to cool until the braze material hardens, after which the vibration is terminated. The remaining sleeve or plug is then machined out of the two bores leaving the tubular part brazed to the metal body.

A tool body is cold formed by inserting a blank into a die which defines a portion of the outer surface of the tool body after which a punch applies an impact to the blank causing the outer surface of the blank to conform to the contour defined by the die. The tool body has a tapered forward end, a central radial flange and a rearward cylindrical shank. To cold forge a fixed diameter in the central flange of the tool the forging die has a cylindrical portion having an inner diameter equal to the desired diameter of the flange, the die having an end to allow overfill to be released forward of the fixed diameter portion. Also, a shoulder is formed between the cylindrical shank and a frustoconical portion between the shank and rear surface of the flange. Finally, the shank has an elongate cylindrical hub to facilitate alignment of the tool.

A cutting tool has a tool body with a hardened insert brazed into a cylindrical seat having a given diameter at the forward end of the tool body. The insert has a cutting tip portion, a generally cylindrical base portion positioned behind the tip, and a frustoconical midsection extending from the tip section to the base section. The base section of the insert has a diameter substantially less than the diameter of the seat and a plurality of radial projection extending outward of the base section assist in aligning the base section within the seat prior to brazing the parts together.
