What is a compass?
The compass is a small hand or power supply with a narrow tapering blade used for cutting curves and internal profiles in leaves of wood, PVC and plasterboard. These devices are also useful for use in small limited spaces where larger saws are impractical. The compass saws have solid or retractable blades that are usually interchangeable. This allows you to use the dull blades and several blade lengths and dental spacing with one handle. The compass saws are similar to keyhole saws, except that they are slightly larger and typical blade lengths run between 5 and 15 inches (127 and 381 mm).
Compass saws are usually used to reduce unpleasant holes from the internal surfaces of various common building materials. They are also often used to cut PVC or wood tubes in small cramped areas. The saw can be used to reduce most plastic, non -ferrous metals, soft wood panels, pressed wood and plasterboard. Their narrow tapered blades allowEasy cutting of circular holes and small curvature curves. These saws are generally operated manually, even if the electric reciproce of compass.
The compass blade is either a solid or retractable design. They are usually interchangeable, allowing easy replacement of blunt or broken shoulder blades. This also allows you to use a range of blade lengths and teeth sphering with one eating handle for slices in material selection. The most popular blade lengths are 10 to 12 inches (254-304 mm), although different lengths are also commonly used for specific applications. For example, short blades allow the saws to be used to cut out shapes from one side of the plasterboard without penetrating the opposite sheet.
When cutting holes in soft materials, such as dry, it allows a narrow pointed blade to achieve initial penetration without having to pilot H before drilling holes. The ability to pull the blade on an opttiMal length on some saws also prevents unwanted blade bending and the blade breaking when cutting harder materials. Most of the SOMPAS SAW blades have teeth that only cut on the pull, helping to prevent the blades from cutting when cutting. This function also ensures clean cuts even when working in limited spaces.
6 The general rule is a denser and heavier material, the softer the dental pitch. The blade for general purposes will have a dental pitch between 8 and 10 teeth per inch (25.4 mm). The blade designed for harder wood and aluminum can have tooth density of up to 20 teeth per inch. Compass saw the blades used for softer fibrous boards or dry walls has only a few teeth per thumb.
