hole saw , also: holesaw

A hole saw is a metal cylinder with saw teeth around one end of the opening; the other end fits onto a special drill bit included with the saw.

You need a different size of hole saw for each size of hole: you can buy multiple hole saws which have 'nests' of different sizes.

It is roughed up with a "hole saw" from a hardware store; the hole saw is dragged by hand, back and forth across the screen.

Many types of specialised drill bits for boring clean holes in wood have been developed, including brad-point bits, Forstner bits and hole saws.

The depth to which a hole saw can cut is limited by the depth of its cup-like shape.

Most hole saws have a fairly short aspect ratio of diameter to depth, and they are used to cut through relatively thin workpieces.

By snapping the blades into different grooves on the disc, a hole saw of a wide variety of sizes can be constructed.

Drilling with hole saw may be required in doors lacking a hole for assembly.
