A mattock (/ ˈ m æ t ə k /) is a hand tool used for digging, prying, and chopping. Similar to the pickaxe, it has a long handle and a stout head which combines either a vertical axe blade with a horizontal adze (cutter mattock), or a pick and an adze (pick mattock).
When a component is produced with one single punch and die where the entire outer profile is cut in a single stroke the tool is called a blanking tool. Blanking is the operation of cutting flat shapes from sheet metal. The outer area of metal remaining after a blanking operation is generally discarded as waste. Size of blank or product is the ...
It is a power-driven metal cutting machine which assists in managing the needed relative motion between cutting tool and the job that changes the size and shape of the job material. [1] The precise definition of the term machine tool varies among users, as discussed below. While all machine tools are "machines that help people to make things ...
The ends of a digging bar are shaped for various purposes. [3] Typically, each end has a different shape so as to provide two different tool functions in one tool. Common end shapes include: Blunt — a broad, blunt surface for tamping. Point — for breaking hard materials and prying. Wedge — an unsharpened blade for digging, breaking and ...
A shovel is a tool used for digging, lifting, and moving bulk materials, such as soil, coal, gravel, snow, sand, or ore. [1] Most shovels are hand tools consisting of a broad blade fixed to a medium-length handle. Shovel blades are usually made of sheet steel or hard plastics and are very strong.
Ceremony hammer of a miner VEB Kombinat Senftenberg - with honorary uniform. A pickaxe, pick-axe, or pick is a generally T-shaped hand tool used for prying.Its head is typically metal, attached perpendicularly to a longer handle, traditionally made of wood, occasionally metal, and increasingly fiberglass.
Cutting tool materials must be harder than the material which is to be cut, and the tool must be able to withstand the heat and force generated in the metal-cutting process. Also, the tool must have a specific geometry, with clearance angles designed so that the cutting edge can contact the workpiece without the rest of the tool dragging on the ...
Grinding is a subset of cutting, as grinding is a true metal-cutting process. Each grain of abrasive functions as a microscopic single-point cutting edge (although of high negative rake angle), and shears a tiny chip that is analogous to what would conventionally be called a "cut" chip (turning, milling, drilling, tapping, etc.) [citation needed].
