Two primary tools are used for brick cutting. A mason's hammer with a chisel-pointed end makes precise cuts through sharp, well-aimed strikes for basic shaping. For more complex shapes requiring higher precision, a power saw equipped with a water-cooled diamond blade is used. The choice depends on the complexity and accuracy needed for the specific brick shape.

A half-bat is a brick cut to half its original length, while a three-fourth bat is cut to three-fourths its original length. Both are standardized cut brick sizes used when full bricks cannot fit into remaining wall spaces. These sized bricks help masons fill gaps efficiently and maintain consistent bonding patterns in masonry construction.

Queen closers match the length and thickness of standard bricks but have half the width. King closers are shaped with one end cut to half the width, creating a slanted corner from the midpoint of two adjacent edges. Both serve specific purposes in brick masonry bonding patterns, with queen closers commonly used in English bond patterns.

A water-cooled diamond blade provides higher precision when cutting bricks into complex shapes compared to manual hammer methods. The water cooling prevents blade overheating and material damage, while the diamond blade's hardness cuts through brick efficiently. This method is essential when exact dimensions and intricate shapes are required for specialized masonry applications.

Beveled closers and mitered closers are specialized cut brick forms tailored to specific construction needs beyond standard sizing. Like other cut bricks such as quarter bats, these shapes are cut to achieve desired structural and aesthetic outcomes in masonry. Each type serves a particular purpose in achieving proper brick alignment and wall appearance.

A mason's hammer with a chisel-pointed end is used for basic brick shaping when a full brick cannot fit into remaining wall spaces. This hand tool is practical for simple cuts and on-site adjustments where precision requirements are moderate. Power saws are reserved for complex shapes requiring higher accuracy, making the hammer the efficient choice for straightforward cutting tasks.

Cut brick sizes such as half-bats and three-fourth bats allow masons to fill remaining spaces precisely without wasting material. These standardized cut forms enable efficient wall construction by reducing gaps and maintaining consistent bonding patterns. Using appropriately sized cut bricks improves structural integrity and reduces the need for excessive mortar adjustments during laying.
