Lathe tool bits, blanks, and sets are used on lathes to perform turning, boring, grooving, and threading operations. Lathe tool bits are single-point tools with cutting edges at one end that cut features into a workpiece as it rotates against the tool. Lathe tool bit sets include multiple single-point tool bits in different sizes or cutting-tip styles. Lathe tool blanks are solid bars that can be machined to make custom single-point lathe tool bits.
