Annular cutters can also be used to make holes in pipes and tubes without dimpling and deburring. To make a hole in a tube or pipe easily an annular cutter should be used with a magnetic base drilling machine and a tube/pipe clamping device. The tube clamping device is a metallic device that is clamped on the tube with an adjustable chain.
Where the high temperatures and sources of ignition required by hot cutting are not desirable, air- or hydraulically-powered pipe cutting machines are used. These comprise a clamshell or chain-mounted cutting head holding a tool steel and feed mechanism which advances the tool a set amount per revolution round the pipe.
Plastic tubing cutters, which resemble a pair of pruning shears, may be used for thinner pipes and tubes, such as sprinkler pipe. For use on thicker pipes, there is a pipecutter with a sharp wheel and adjustable jaw grips. These are used by rotating it around the pipe and repeatedly tightening it until it cuts all of the way through. [1]
A gimlet is a hand tool for drilling small holes, mainly in wood, without splitting. It was defined in Joseph Gwilt's Architecture (1859) as "a piece of steel of a semi-cylindrical form, hollow on one side, having a cross handle at one end and a worm or screw at the other".
Intermediate metal conduit (IMC) is a steel tubing heavier than EMT but lighter than RMC. It may be threaded. Electrical metallic tubing (EMT), sometimes called thin-wall, is commonly used instead of galvanized rigid conduit (GRC), as it is less costly and lighter than GRC. EMT itself is not threaded, but can be used with threaded fittings that ...
Tungsten carbide hole saw with arbor A 52 mm (2.0 in) hole saw with pilot bit A 115 mm (4.5 in) diamond hole saw. A hole saw (also styled holesaw), also known as a hole cutter, [1] is a saw blade of annular (ring) shape, whose annular kerf creates a hole in the workpiece without having to cut up the core material.
One of the most common ways to produce such threaded holes is to drill a hole of appropriate size with a drill bit and then tap it with a tap. Each standard size of female screw thread has one or several corresponding drill bit sizes that are within the range of appropriate size—slightly larger than the minor diameter of the mating male ...
A modern core drill is a drill specifically designed to remove a cylinder of material, much like a hole saw. The material left inside the drill bit is referred to as the core. Core drills used in metal are called annular cutters. Core drills used for concrete and hard rock generally use industrial diamond grit as the abrasive material and may ...
