20080258536 | High-impact Resistant Tool - A high impact resistant tool comprises a steel shank. The steel shank has a hollow portion and first and second ends. The shank is adapted for insertion into a holder and connection to a driving mechanism. A carbide cap is joined at a brazed joint to the first end of the shank. | 10-23-2008 |
20100237684 | Core Breaker With Dust Suppression System - A core breaker for use with a continuous mining machine used to cut earth strata wherein the continuous mining machine has at least two spaced apart cutting drums whereby each one of the cutting drums cuts the earth strata leaving a core. The core breaker includes an elongate support positioned mediate of the two cutting drums. In one aspect, the elongate support includes a channel formed therein. The core breaker further includes a plurality of tool components attached to the elongate support. The core breaker also includes a plurality of spray nozzles positioned adjacent to the tool components. In one aspect, the plurality of spray nozzles each have a first end in fluid communication with the channel formed in the elongate support and a second end positioned adjacent an outer surface of the elongate support. The tool components may be, for example, a breaker wedge or a cutting tool such as a conical bit. | 09-23-2010 |
20110080037 | Rotatable Cutting Tool With Through Coolant - A rotatable cutting tool for use in impinging earth strata such as, for example, asphaltic roadway material, coal deposits, mineral formations and the like. The rotatable cutting tool includes a cutting tool body having a through coolant channel and a two-piece head portion, e.g., the head portion of the cutting tool body having a base portion and a nose portion with a hard tip cutting insert affixed to the nose portion. The through coolant provides for cooling the hard tip cutting insert during operation of the cutting tool. In addition, the through coolant also provides for suppressing dust created by the rotatable cutting tool during operation. | 04-07-2011 |
20130241266 | Chisel Holder - The invention relates to a bit holder for an earth working machine, in particular a road milling machine, having a support member onto which an insertion projection is indirectly or directly attached on an insertion projection side, the support member comprising two first and/or two second stripping surfaces that are at an angle to one another, and the support member having a working side that comprises a bit receptacle. In order to achieve a stable and long-lived configuration for such a bit holder, provision is made according to the present invention that the first and/or second stripping surfaces diverge from the insertion projection side toward the working side. | 09-19-2013 |
20140117741 | Chisel Holder For A Soil Treatment Machine - The invention relates to a bit holder for an earth working machine, in particular a road milling machine, that comprises a bit receptacle in the region of a working side of a support member and that indirectly or directly carries an insertion projection on an insertion projection side of the support member, the support member comprising two stripping surfaces [first or second stripping surfaces] that form a stripping surface pair and are at an angle to one another. In order to achieve a stable and long-lived configuration with such a bit holder, provision is made according to the present invention that the support member comprises at least one further stripping surface that is at an angle to the two stripping surfaces of the stripping surface pair. | 05-01-2014 |

20110006587 | Water Spray Assembly etc. - A water spray assembly for replaceable location in a receiving bore of a pick box, which pick box is also adapted to receive a replaceable mineral cutter pick, is constructed from two components. One component is a spray body and the other component is a co-axial spray nozzle. The two components are releasably connected together by screw threads, whereby the spray assembly may either be removed from or inserted into, its receiving bore as a whole, or alternatively as individual components. | 01-13-2011 |
20120119563 | Cutting Tool with Nozzle for Spraying Water on a Cutter Bit - A cutting tool has a holder block and a sleeve. The sleeve includes a shank and an enlarged flange at an end of the shank. The sleeve shank is received in a hole in the holder block, with the flange against a surface of the holder block and the sleeve shank facing the holder hole wall. A first fillet extending between the holder bore wall and a second fillet extending between the sleeve shank and sleeve flange cooperatively form an annular flow passage for flow of water from the holder into the sleeve. | 05-17-2012 |
20120175939 | BIT HOLDING SYSTEM WITH AN OPENING FOR REMOVAL OF BROKEN BITS - A cutting tool assembly including a bit holder having a forward portion, a rearward portion, and a generally planar mounting surface between the forward and rearward portions. The forward portion defines a front aperture having an axis inclined relative to the mounting surface, and the rearward portion defines a rear aperture open to the front aperture. A cutting bit is mounted in the front aperture and includes a rearward end accessible through the rear aperture of the bit holder rearward portion. | 07-12-2012 |
20140312678 | Mineral Cutter Pick Etc - A water spray system particularly, but no exclusively, for mineral mining, comprising a pick ( | 10-23-2014 |
