Bolt cutters

Function as release devices, such as rod or bolt cutters that sever a rod or link between two items of hardware. A cable cutter functions by forcing a blade into a receiving anvil, severing connectors interposed... 

Miscellaneous tools and paraphernalia—A variety of small tools could be needed, as well as shovels, pickaxes, axes, rope, flares, emergency lights, sawhorses, a bullhorn, a chain saw, a metal cuffing saw, a bolt cutter, and a jaws of life metal spreader. Special nonsparking tools may be required where sparks may ignite flammable vapors. 

Do locks have substantial strength to prevent removal without applying excessive force such as bolt cutters [29 CFR 1910.147 (c)(5)(ii)(C)(l)]... 

To remove the lock, a bolt cutters or master key may be used. OSHA says that it is acceptable to use a master key if removing the lock is performed under the employer s direction and in accordance with the procedures above (these procedures and associated training must be outlined in the employer s energy control program). OSHA says, the one person, one lock, one key practice is the preferred means and is accepted across industry lines, but it is not the only method to meet the language of the standard. ... 

In a February 28, 2000 letter of interpretation, OSHA states that bolt cutters, or other devicedestructive methods, are not the only permissible means by which to remove a lockout device, if the employer can demonstrate that the specific alternative procedure, which the employer follows prior to removing the device, provides a degree of safety that is equivalent to the removal of the device by the authorized employee who first affixed it. 

Machine screws (or bolts) require special tools. The combination wrench is one type of hand tool used with machine screws. The adjustable wrench is more versatile, allowing the technician to use it with different sizes of machine screws (see Figure 8-20). We may also use pliers, second-class levers, during the combining process. Pliers can be found in various types (see Figure 8-21). Slip joint pliers allow material to be held firmly. Needle nose pliers can hold smaller items. Diagonal pliers (cutters) are actually a shearing tool for wire. 

A spotface cutter. Fig. 8.15, is used to provide a flat and square seating for a screw, bolt or nut on the surface of the workpiece, usually on the surface of a rough casting which would not otherwise provide a sufficiently accurate seating. The spotface is similar to a counterbore cutter, but has teeth on the end only. It will cut to only a very limited depth and caimot be used to counterbore. Counterbore cutters, on the other hand, can be used to spotface. 

Designed for milling tee slots in machine tables, this cutter has teeth on its circumference and on both sides. To reduce chatter and provide maximum chip clearance, the teeth are alternately right-hand and left-hand helix, and each alternate side tooth is removed. To produce a tee slot, the groove is first cut using a side-and-face cutter, end mill or slot drill and finally the wide slot at the bottom is cut using a tee-slot cutter. Fig. 11.8(k). The shank is reduced to clear the initial groove. This cutter is available for standard tee slots to suit bolt sizes up to 24 mm. 

To machine the broach debris, ellptlcal nosed cutters of various angles were tried and non contact stand off ultrasonic techniques similar to that used for fishplate Interfaclal oxide measurements (6) evaluated. After a number of trials It was found that If the socket was machined out to a flat base of approximately 4mm diameter a 0° compression wave transducer could be used to generate an ultrasonic beam parallel to the bolt axis In a conventional contact type test, the machined socket head conveniently providing a reservoir for couplant (In this case ethylene glycol) prior to application of the probe. 

Prior to Inspection at L83, minor modifications were made to the equipment. The cutter length was extended to cut to 10mm depth and the transducer repositioned. This overcame the problem and data was obtained from all four bolts at this location. 

Strand chopper n. (1, pelletizer) A type of cutter into which multiple extruded and chilled strands are fed for cutting into short lengths about equal to the strand diameter. The strands are fed perpendicular to the edge of a thick stationary knife and are sheared off by several rotating knives bolted to a massive cylindrical head. The pellets so formed are discharged into a shipping container or conveyed into... 

The contents of chemical munitions may also be under pressure and liquid agent can spray as they are opened. Other problems encountered by some have included seized bolts and the problem that lubricants used to unseize the bolts must be used in a manner that does not interfere with CW agent monitoring equipment. Equipment used to open munitions, such as pneumatic wrenches and saw pipe cutters, must be used with care, especially in cases where the munitions still have their fuses attached. 

To begin, cut a board the length of a radius of the circle you wish to cut, plus extra for a handle. Mark a line across the board for the saw slot (1) and bore it out (2) (be careful of saw kick-back as you do this). Clamp the edger to the sawbar, insert the bar through the slot and bolt the unit to the board (3). Measure from the inside edge of a chain cutter and mark the desired radius in the center of the board (4). Drive a spike through the board at that mark for a pivot (5), and tack the spike into the center of the circle. Start the saw and enter the cut by pushing the handle end of the board (6).
