Bump Knurling Holders for Swiss Machines

Bump style knurling can be performed on any type of lathe. This cost effective method is ideal for larger diameter parts as the amount of radial force required to produce the knurled pattern can be significant in some materials. If part deflection is of concern, we recommend using an alternative knurling method such as straddle knurling or axial feed knurling.
