Bump type knurl holders are best suited to shorter work or longer work if knurling can be done close to the chuck or tailstock.  When a long, raised diamond pattern is required, a different type of holder, using one right hand and one left hand knurl is recommended.  A carbide pin and hex wrench are included.  Knurl is not included.

 

Setup Procedure:    Mount the holder perpendicular to the spindle, in the turret or cross-slide.  Move the holder toward the spindle until the knurl just contacts the work.  Adjust a small amount deeper and make a test roll.  If the knurl pattern is too shallow adjust it again.

 

*OR BH-BPS IS LEFT HAND STYLE, MIRROR OF ABOVE VIEW.   OTHER HOLDERS SUPPLIED RIGHT HAND STYLE, AS SHOWN.
