125036000 | TOOLS | 9 |
20090145417 | Power tool stand and tool coupling for mounting a portable power tool on the stand - A power tool stand includes a guide carriage ( | 06-11-2009 |
125038000 | Surface traversing | 3 |
20080295822 | RAIL GUIDE WITH BEARINGS FOR TILE SAW - A tile cutting machine includes a tool support assembly having at least one rail with a rail bearing associated therewith for selective movement there along. The rail bearing includes a housing having a bore therethrough. A plurality of slots are located in the housing adjacent the bore. The slots receive an axle pin having a wheel thereon to provide a roller bearing. Portions of the wheels extend into the bore and ride along an outer surface of the rail when it is received in the bore. | 12-04-2008 |
125039000 | Diamond | 2 |
20100031947 | Blade - A blade comprises a strip having a main body portion and an edge portion. Cutting medium in the form of a diamond grit is secured to the strip by braze material. The edge portion is thinner than the main body portion. | 02-11-2010 |
20100175677 | Diamond wire saw - A diamond wire saw with an improved structure is provided. The diamond wire saw is capable of cutting operation along curved paths with small radii of curvature. In addition, the diamond wire saw is configured to prevent a diamond particle layer covering a surface thereof from flaking off. Thus, the diamond wire saw has improved durability and enhanced sharpness as well as low production cost. | 07-15-2010 |
125040000 | Impact | 5 |
20110283985 | DEMOLITION BIT WITH BOUNCE BACK BIT EXTRACTOR - The invention provides a demolition tool comprising a chisel and a bounce back element. | 11-24-2011 |
20120060816 | Isolator Plate Assembly for Rock Breaking Device - A rock breaking device employs a falling weight and a striker pin or other tool held within a tool holding structure supported by a recoil assembly includes a number of isolator structures that protect the rock breaking device by absorbing excess forces that may be applied to the recoil assembly. Each isolator structure includes a front plate that extends below a lower side of a recoil tube flange. In new rock breaking devices, the front plates may be incorporated as part of the isolator structures. Alternatively, an existing rock breaking device can be retrofitted by welding a heavy plate onto the front of an existing front plate of the isolator structures. The heavy plate extends beyond the lower side of the recoil tube flange to provide greater strength. | 03-15-2012 |
20130125872 | HARD FACE STRUCTURE, BODY COMPRISING SAME AND METHOD FOR MAKING SAME - A body comprising a steel substrate and a hard face structure fused to the steel substrate, in which the hard face structure comprises at least 1 weight percent Si, at least 5 weight percent Cr and at least 40 weight percent W and substantially the balance of the hard face structure consisting essentially of an iron group metal M and C, M being selected from Fe, Co and Ni or an alloy thereof; the hard face structure including a plurality of elongate or platelike micro-structures having a mean length of at least 1 micron, a plurality of nano-particles having a mean size of less than 200 nanometres, and a binder material; the micro-structures comprising more than 1 weight percent Cr and a phase having the formula M | 05-23-2013 |
125041000 | Bush hammers and chisels | 1 |
20150096548 | CHISELS - A chisel includes an elongate shank portion composed of a first steel, and a working end portion composed of a second steel that is different than the first steel. The working end portion is joined to the shank and configured to chisel a workpiece. The joined shank portion and working end portion has been heat treated to cause the first steel of the shank portion to adopt a first microstructure comprising bainite, the second steel of the working end portion to adopt a second microstructure comprising martensite, and the working end portion to have a greater hardness than the shank portion. | 04-09-2015 |
125043000 | Miners' picks | 1 |
20140102433 | MAGNETIZED PICK AXE AND METHOD OF FORMING SAME - A pick axe is provided with recesses formed in the concave surfaces of its pick and its blade which are then filled with adhesive into which corresponding magnetic slugs are then bedded. The adhesive is faired with the adjacent surfaces around each recess and once set up or cured fully encapsulates the magnetic slug within its larger recess to isolate the higher frequency, or the higher energy components of each pick axe impact to protect the received slugs from demagnetization and/or fracture. | 04-17-2014 |
