Description of the technology

Purpose of use

hole designing (creating a machining base for the next hole machining operation)

Use in industry

all industries

General characteristics

Countersinking is a method of machining in which an cavity is made in solid material along the axis of the hole to be drilled. This process is carried out using a rotating tool called a centre drill. During drilling, the primary (rotary) motion is made by the tool or the workpiece (lathe countersinking). The feed motion is performed in a direction parallel to the axis of the centre drill by the tool or workpiece.
