Key broaches

Key broaches are used for broaching key slots in orifices. The dimensions for key broaches with shanks are established by the applicable standards. Typically, key broaches have the same design features and shapes as spline broaches. When using key broaches, either single or group cutting pattern is used. The group cutting pattern provides for higher efficiency due to the number of teeth in the group (2) and two angular chamfers on the first tooth.
