Pipe cutters - answerused to cut steel, brass, and iron pipe.
Tubing cutters - answerused to cut thin-wall iron, brass, steel, copper, and aluminum
tubing.
Putty Knives/Scrapers - answerStep Hold the knife in one hand at an effective angle to
the work, and scrape the gasket off using smooth, even strokes.
Diagonal Cutters - answerare small pliers used to cut wire cotter pins, and other items
made of light material that are inaccessible with other types of cutters.
Tin Snips - answerThey are used to cut light-gauge sheet metal where the shape,
position, or location prevents the use of power metal-cut- ting tools.
Red- handled aviation snips cut to the - answerLeft
Green-handled aviation snips cut to the - answerRight
Yellow-handled aviation snips cut a - answerstraight line.
Dies - answerare used to cut external threads on bolts and rods.
Taper taps - answerare used when starting tapping operation or when tapping through
holes. They have a chamfer length of 8 to 10 threads.
Thread Gauges - answeralso known as screw pitch gauges are used to measure the
pitch of threaded fasteners.
Sheave Gauges - answerAre used to measure the side wall wear of a belt sheave.
Packing Pullers - answerused remove packing mate- rial from valves, pumps, and some
motors.
, Extractors - answerUse ____ if the screw or tap is broken near or below the surface of
the work
Spiral Screw Extractors - answeror easy-outs, are reverse- threaded to remove right-
hand threaded screws or bolts.
Portable grinders - answerMaintence craftworkers use ___ for beveling
End Grinders - answerType of grinder designed to reach into small areas with limited
working space.
Vertical Grinders - answervery similar to angle grinders. but are set at a 90-degree
angle from the handle.
Grinder accessories - answerWhen selecting a grinding wheel for a given job, two
factors must be considered. wheel must be suited to the material being ground, and the
maxi- mum rotational speed of the wheel must be rated higher than the rotational speed
of the grinder. correct wheel can be identified by referring to the manufacturer code
stamped or printed on the wheel.
Safty warning grinding - answerAlways grind with the direction of the bevel and position
the wheel to the bevel, so that if it kicks off, it will kick off from you.
PIPE THREADING MACHINES - answermultipurpose power tools that center, hold, and
rotate pipe, conduit, or bolt stock while cutting, reaming, and threading operations are
performed.
Correct threads - answerIf the threads are correct, you should be able to screw a fitting
three and a half revolu- tions by hand onto the new threads.
Thread classes - answerClasses each 3A other and by 3B the allow degrees of
minimum tolerance distinguished clearance and permitted.
Nominal size - answerApproximate diameter of the fastener.
buttress thread - answerOne side of the thread cut square and the other cut at a slant. It
has great strength along the thread axis in one direction only. This thread form is used
to screw thin tubular parts together
Grade markings - answerGenerally, the higher-quality steel fasteners have a greater
number of marks on the head.
Cap Screws - answer____ screws often used on high-quality assemblies requiring a
finished appearance.
