A stonemason's hammer, also known as a brick hammer, has one flat traditional face and a short or long chisel-shaped blade. [1] It can thus be used to chip off edges or small pieces of stone, cut brick or a concrete masonry unit, without using a separate chisel. The chisel blade can also be used to rapidly cut bricks or cinder blocks.
Stone chisels are used to carve or cut stone, bricks or concrete slabs. To cut, as opposed to carve, a brick bolster is used; this has a wide, flat blade that is tapped along the cut line to produce a groove, then hit hard in the centre to crack the stone. Sculptors use a spoon chisel, which is bent, with the bevel on both sides.

Percussion tools for hitting - such as mallets, axes, adzes, bouchards and toothed hammers. Tools for rough shaping of stone, to form a block the size needed for the carving. These include feathers and wedges and pitching tools. Chisels for cutting - such as lettering chisels, points, pitching tools, and claw chisels. Chisels, in turn, may be ...
Compressed-air powered tools have made working of stone less time-intensive. Petrol and electric-powered abrasive saws can cut through stone much faster and with more precision than chiseling alone. Cemented carbide-tipped chisels can stand up to much more abuse than the steel and iron chisels made by blacksmiths of old.
Bronze plugs and feathers were then driven into grooves which had been previously cut with a chisel and mallet. This was the most common method used by the Egyptians for quarrying limestone and sandstone. Evidence of this method for cutting obelisks in the quarries of Aswan can clearly be seen. [4] The technique was also used by the Romans. [5]
The square chisel mortiser (also called hollow chisel mortiser), similar to a drill press in many respects, combines the cutting of a four-sided chisel with the action of a drill bit in the center. The bit clears out most of the material to be removed, and the chisel ensures the edges are straight and clean.
Although each blow is of relatively low force, these thousands of blows per minute are more than adequate to break up concrete or brick, using the masonry drill bit's carbide wedge to pulverize it for the spiral flutes to whisk away. For this reason, a hammer drill drills much faster than a regular drill through concrete, brick, and thick lumber.
