Boring tools are used to cut or finish the inner diameter of holes. Products include both automated industrial machinery and handheld tools such as drills and bits, punches, awls, and chisels. Boring tools such as heavy-duty boring mills may be either vertically or horizontally oriented, and use an adjustable mount with a cutting tool which is lowered onto or pressed into the work piece. Boring tools use a variety of bits to determine the size and shape of the holes drilled in the material, and can include mortising chisels, spur bits, and countersinks. A boring tool can be used on metals, wood, and plastics.

Boring tools include pointed tools for making simple holes in wood, leather, fabric, or paper. Awls and brad drivers are used to create holes by either punching through the material or punching a brad, or thin wire nail, through the material. An awl is a sharp, pointed tools used to create holes. A brad driver is a tool that hold brads in place so they can be pushed into the wood. Boring tools for handheld usage also include braces and hand drills. Braces are handheld manual boring tools that consist of a doorknob-shaped handle and a horizontally-oriented rotating arm that can be hand-cranked to turn a drill bit. The drill bit is placed on the material. One hand holds the knob-shaped handle while the other hand moves the rotating handle in a circular motion to drive the bit. Hand drills consist of a drill bit and handle fitted with a manually-turned, vertically-oriented gearing mechanism that turns the bit.

Handheld boring tools include punches and chisels for working on wood or metals. A punch and chisel set typically includes a set of tools such as pin punches, taper punches, center punches, chisels with varying sizes of blades, and a chisel punch gauge. Boring tools also include scotch or ring auger bits for cutting different sized holes. Auger bits consist of a helical-shaped bit for carving out smooth holes in wood, rock, or ice.
