| Induction motor |
| Induction motors are typically found on the larger stationary type tools such as radial arm saws, scroll saws, table saws, band saws, belt/disc sanders, drill presses and planers. They are very quiet with a long life since they do not have any brushes and are therefore more reliable. However, these motors are much larger than the comparable Universal or Permanent Magnet motor and have a higher cost and are limited to lower speeds. |
| |
| In-line filter |
| In-line filters remove moisture, oil impurities and small particles. They must be located a minimum of 15 feet away from the compressor to allow the air to cool and for moisture to precipitate. |
| |
| Anti-Kickback Pawl |
| A guard system attachment with sharp teeth that permits motion in one direction alone, and helps prevent kickback. See "Anti-Kickback Device" above. |
| |
| In-line oiler |
| The in-line oiler helps to continually lubricate air tools that require oiling by delivering the oil through the air flow during operation. |
| |
| Instruction Manual |
| The instruction booklet that comes with every power tool and describes proper operation, care, and maintenance of that tool. Always read and understand the manual before you attempt to use any tool. If you are unsure of the safe and proper set-up, be smart: Look it up in the tool's manual. |
| |
| Jack plane |
| The jack plane is 14 to 15 inches long and is intended for heavy use. It is used immediately after a saw cut to remove irregularities on rough surfaces. |
| |
| Jig saw |
| Jig saws are one of the most versatile cutting portable power tools. The blade is set vertically and moves up and down while the teeth face outward. A manual scroll allows the user to turn the blade in the direction of the cut without having to turn the entire saw body. An auto scroll automatically moves the blade in the direction of the saws direction. An orbital saw not only moves the blade up and down but it moves it on angles as in a reciprocating action. |
| |
| Joiner |
| Joiner (biscuit joiner) is a device that is used to cut slots in two pieces of wood so that the biscuit (along with glue) can be used to join them together. |
| |
| Jointer/planer |
| The jointer/planer allows the user to make long, even sweeps. It is used on the long edges of boards that will be joined edge to edge. This smoothing process eliminates possible gaps between the two pieces when they are placed side by side. Use this tool to prepare and finish cut stock for more precise project work. Wood is sized or smoothed by being passed along a rotating cutter head. The jointer squares edges of lumber and flattens boards that are slightly warped. The planer is used more to smooth surfaces or reduce wood faces and edges. |
| |
| Keyhole saw |
| Has a narrow blade that usually tapers to a small point. It is used mainly for cutting out holes and other irregular shapes in wood, wallboard, and lather and plaster. |
| |
| Kickback |
| Kickback occurs when the material being cut gets jammed in the blade and is thrown back towards the user. |
| |
| Known Grounded Outlet |
| A grounded outlet that's been tested and proven to have its ground terminal properly connected. Don't assume that every three-pronged outlet is grounded. You can't always judge an outlet by its cover. If in doubt, check with a circuit analyzer, or have it checked by a qualified electrician. |
| |
| Level |
| The level is used to determine the true horizontal (level) or vertical (plumb) of a surface. A slim, rectangular tool, the level is commonly used for grading, levelling, or aligning fences, driveways, or stonewalls. The air bubble in the liquid centres between two markings on the vial indicate level or plumb. |
| |
| Lineman's pliers |
| Also called combination or engineer's pliers are a standard type of solid joint plier. The flat jaws may be used for holding or pulling sheet metal or wire. Side cutting jaws add wire cutting capabilities. |
| |
| Listed |
| As in "UL Listed" or "CSA Listed," meaning approved for use by Underwriters Laboratories or the Canadian Standard Association. |
| |
| Long nose pliers |
| Pliers have serrated, tapering jaws to work in confined spaces and hardened cutting edges. Long nose pliers are used to form loops and bends of all sizes. |
| |
| Masonry Drill Bit |
| An accessory placed in the chuck of the drill that enables the drill to create holes in masonry materials such as brick, concrete, etc. |
| |
| Maximum Safe Speed |
| Tools maximum operation speed is indicated on the tool nameplate. Check the tool accessories and don't use if their rated speed is lower than that of the tool. |
| |
| Metric sizes |
| Tools that use the metric measurement system of millimetres - ie. 10mm, 11mm, 12mm |
| |
| Mitre box |
| A device to guide the saw in making mitre cuts. |
| |
| Mitre saw |
| A (bench power) mitre saw is almost like a portable radial arm saw. It takes the grunt work out of using a backsaw and mitre box. It makes quick, accurate crosscuts and mitre cuts, as well as bevel and compound cuts. A basic mitre saw cuts basic mitre angles; a compound mitre saw makes mitre and bevel cuts separately or at the same time. A slide compound mitre saw combines the functions of a mitre saw with that of a radial arm saw. The sliding blade allows for cutting wider pieces. |
| |
| Mitre square |
| The mitre square is the smallest square and has a bevel angle to mark both halves of a mitre joint at 45 degrees. |
| |
| Nail puller |
| The nail puller is a tool that's valuable in the shipping and receiving rooms of plants and stores to open wood boxes and crates. It's also the ideal tool for pulling nails from lumber that is to be reclaimed, such as loose boards which must be repositioned. |
| |
| Nut drivers |
| These tools have handles and shafts similar to those on screwdrivers, but instead of a blade, the handle ends in a socket with a head designed to fit over nuts for easy tightening and loosening. |
| |
| Open-end wrench |
| Wrench with a different size opening at either end, it is designed to engage the nut or bolt head from the side. |
| |
| Overreaching |
| A big mistake often followed by big trouble. When using power tools, always make sure you've got good balance and are firmly planted on your two feet. |
| |
| Pad sander |
| Pad or finishing sanders are capable of providing a smooth, even finish over a variety of woods. A straight-line sander uses a straight back and forth motion of the pad to produce a fine finish. An orbital sander creates a tight circular motion and is best applied to finish sanding and limited paint removal. Dual motion sanders gives the user the ability to choose between straight-line strokes and orbital motion for finish sanding or stock removal. A random orbital sander simulates hand sanding for finishes that are virtually free of swirls, scratches and burns. |
| |
| Permanent Magnet motor |
| Permanent magnet motors exist on battery powered tools and variable speed tools. They are compact and have a high starting torque as well as a high stall torque. However, this type of motor requires an inverter which adds to the cost of the tool. As well, its life is limited by the quality of the brushes in the motor. |
| |
| Phillips screwdriver |
| Fits round or flat head fasteners with a cross shaped slot on the head. |
| |
| Pin punch |
| The pin punch is used to drive various sizes of taper pins, cotter pins, or bolts out of holes. |
| |
| Pipe clamp |
| Clamps that use different size piping and clamps to adjust according to the exact requirements of the project. It is useful for repairing glued joints on chairs and other furniture or to clamp wood together for dowelling and gluing. |
| |
| Plane |
| A plane is a hand tool designed to trim wood by shaving it. An angled blade extends below the bottom edge of the tool so that it shaves the wood as it is drawn across its surface. Planing with the grain of the wood leaves the wood with a smooth surface. Planing across (or against) the grain leaves a rougher surface. |
| |
| Plate joiner |
| The plate joiner is used specifically to strengthen wood joints in applications such as furniture making. The joiner cuts grooves of varying depths into the adjoining side of two work pieces. Plates, or biscuits, are then glued into these grooves to reinforce the newly formed joint. |
| |
| Plumb bob |
| The plumb bob is used to find a true vertical (plumb) line. The bob is a weight attached to a string; the force of gravity pulls the bob straight down so that the string follows the true vertical. |
|
|
| Plunge Router
|
| A plunge router is just like a standard router however they have the ability to plunge into the work while a router has a setting fixed before being used on the work piece. |
