20150130258 | Dirt and Rock Cutting Bit Tool - A dirt and rock cutting tool includes a cutting bit mounted on a bit holder. The cutting tool is secured to a bit holder in a manner that allows infinite rotational positioning of the cutting bit but substantially prevents rotation of the cutting bit once secured to a bit holder. The bit holder includes a planar shoulder and a shank extending from the planar shoulder. Shank has a terminal end which includes a threaded bore member. The bit holder includes a receiver dimensioned for receiving the shank. At least one hardened pin member is carried by the bit holder. At least a portion of the tip of the hardened pin extends beyond the surface of the shoulder. Upon securing the bit holder to the bit block, the hardened pin is pulled into the softer metal of the bit block, substantially preventing rotation of the bit holder within the bit block. | 05-14-2015 |
20120181845 | Dual Slotted Holder Body for Removal Tool Access - A plurality of differing horizontal pairs of slot shapes are positioned in the upper body portion of a quick change type bit holder to provide access to a bit extractor tool for removing the bit holder from its associated bit block. | 07-19-2012 |
20120013168 | Spring Biased Rotatable Tool - A rotatable tool has a tool body that is generally symmetrical about a longitudinal axis, an enlarged cutting head, and a rearwardly extending shank. The shank joins the enlarged cutting head at an annular flange. A compressible sleeve is fitted around the shank and a wear ring is around the shank at the forward end of the sleeve. A disc spring is positioned between the radial flange and the sleeve to remove axial play between the shank and the sleeve and to seal the parts so that hard particles cannot enter and interfere with rotation of the tool. | 01-19-2012 |
20100320829 | Bit Holder Usable in Bit Blocks Having Either of a Cylindrical or Non-Locking Taper Bore - A bit holder for use in a bit assembly in road milling, mining and trenching equipment has a hollow generally cylindrical shank and first and second elongate slots positioned in spaced axial relation through the shank. The first slot extends along the shank to the distal end thereof. The second slot may be altered in length and/or shaped to fine tune the outward radial force the shank exerts against the bore of a bit holder block into which it is inserted. | 12-23-2010 |
20100253130 | Slotted Shank Bit Holder - A quick change type bit holder for use in a bit assembly for road milling, road planing, trenching and mining equipment wherein a bit shank extends completely through an axially oriented bit holder bore includes a slotted shank having an outwardly tapered bit holder bore wherein insertion of the bit shank in a bit block acts to slightly collapse the shank which collapses the tapered bore to a generally cylindrical configuration that preferably snugly retains the bit shank rotatably therein. | 10-07-2010 |
20100045094 | Bit Holder Usable in Bit Blocks Having Either of a Cylindrical or Non-Locking Taper Bore - A bit holder for use in a bit assembly in road milling, mining and trenching equipment has a hollow generally cylindrical shank and first and second elongate slots positioned in spaced axial relation through the shank. The first slot extends along the shank to the distal end thereof. The second slot may be altered in length and/or shape to fine tune the outward radial force the shank exerts against the bore of a bit block into which it is inserted. | 02-25-2010 |
