20090033043 | TOOL HOLDER FOR CLAMPING TOOLS BY SHRINK FIT - The invention relates to a tool holder ( | 02-05-2009 |
20090085308 | Tool connector having different driving members - A tool connector includes a outer sleeve having a noncircular bore, and a tool shank slidably engaged in the bore of the outer sleeve and having two end portions slidably engaged in the bore at two end portions of the outer sleeve and extendible out of the end portions of the outer sleeve for engaging with different tool elements or for driving different tool elements. One of the end portions of the tool shank may be engaged into the bore of the outer sleeve when the other end portion of the tool shank is extended out of the outer sleeve for allowing a tool member to be engaged with the bore of the outer sleeve and for allowing different tool elements to be driven by the tool connector. | 04-02-2009 |
20100225074 | DEVICE FOR CLAMPING AND UNCLAMPING A TOOL THROUGH INDUCTIVE WARMING OF A TOOL HOLDER - A device for clamping and unclamping of tools comprising a tool shaft, by which device a sleeve section ( | 09-09-2010 |
20100301569 | "Bi-directional quick change tool-less lever and wedge actuated collet chuck, system and/or method for using the same" - A bi-directional quick change tool-less lever and wedge actuated collet chuck, a system and/or a method provide symmetrical tool bit shank holding pressure before, during and after operation of a rotary-style power tool. The collet chuck is attached to and/or is integrated with high speed, variable speed and/or low speed rotary-style power tools, such as, for example, electrically driven rotary-style power tools and/or pneumatically-driven rotary-style power tools. The collet chuck provides tool-less automatic and/or tool-less manual tightening of the collet around a shank of an accessory for the rotary-style power tool. The collet chuck, the system and/or the method provide tool-less manual loosening of the collet for accessory replacement. | 12-02-2010 |
20120126496 | Method for Making by Assembling a Tool to and in a Tool Holder, and the Tool and Told Holder, and the Assembled Tool and Tool Holder - A method for making by assembling a tool to and in a tool holder, and the tool and tool holder, and the assembled tool and tool holder. The tool is shrink-fitted into a cylindrical bore of the tool holder, and a shoulder of the tool abuts an abutment face of the tool holder. A structure, such as press, a screw, a draw bolt, or a cylinder, for example, is provided to apply an axial force to the cutting tool to force the tool shoulder against the abutment face of the tool holder. | 05-24-2012 |
20130328276 | Quick Change Bit Holder With Ring Magnet - A bit holder assembly for a rotary hand or powered tool, includes a body having a hex shank at its rearward end and a retraction collar slidably disposed on the body. The body has a coaxial hex socket formed therein to allow a tool bit to be inserted thereinto. A coil spring biases the retraction collar forwardly and biases a retaining clip toward the bottom of an angular slot formed in the body. The bit is removed by sliding the retraction collar rearwardly, to compress the coil spring and allow the retaining clip to retract back up the slot. A ring magnet is disposed at the forward end of the retraction collar to magnetize a fastener to retain the fastener to the bit. | 12-12-2013 |
20140210169 | SHRINK FIT TOOL HOLDER - A tool holder has a chuck portion with a retaining bore in which a cutting tool can be inserted. The tool has flat surfaces extending from its end, and circumferential groove at rear ends of the flat surfaces. When the tool is inserted into the retaining bore, first protrusions of the tool holder pass through spaces between the flat surfaces and the inner wall of the retaining bore and fitted in the groove. When the tool is turned, the protrusions move in and engage the side edges of the groove, thus preventing the tool from pulling out of the chuck portion. When the first protrusions are fitted in the groove, second protrusions of the tool holder are located on the flat surfaces. When the tool is turned, the second protrusions are received in ends of the respective spaces, thereby preventing rotation of the tool relative to the chuck portion. | 07-31-2014 |
20150042050 | SHRINK-FIT CHUCK WITH TOOL COOLING - A shrink-fit chuck having a receiving body, a receiving opening for a tool shank, arranged in the receiving body, an accumulation and collection chamber arranged in the front region of the receiving opening and at least one coolant supply channel leading to the accumulation and collection chamber. The accumulation and collection chamber is delimited to the front by a ring bar arranged at the front end of the receiving opening. The internal diameter of the ring bar is adjusted to the internal diameter of the receiving opening in such a manner that as small an annular gap as possible exists between the ring bar and the tool shank. A plurality of outlet openings are provided in the ring bar for discharging to the outside a coolant routed via the coolant supply channel into the accumulation and collection chamber. | 02-12-2015 |

279103000 | Drill type | 2 |
20090008886 | Chuck - A chuck includes a body, a connector, a bit-retaining device and a pusher. The body includes a first section, a second section, a hexagonal hole defined in the first section and a circular hole defined in the second section. The connector includes a substantially circular and toothed section fit in the circular hole of the body. The bit-retaining device is movably mounted on the first section of the body between a releasing position where a bit can be inserted into and removed from the hexagonal hole of the body and a retaining position where the bit can be retained in the hexagonal hole of the body. The pusher is movably disposed in the body and used to push the bit from the hexagonal hole of the body in the releasing position of the bit-retaining device. | 01-08-2009 |
