The A-32 FlexArm is designed for tapping small sizes. Bearings in the unit’s construction allow the operator to line up easily over the hole. With a working range of 11" x 34", the tapping arm stays perpendicular anywhere it is moved on the table. According to the company, the tapping arm was also built with strength and durability in mind. With a 400-rpm pneumatic motor on the unit, it has the capacity to use taps as large as 9/16" (M14) in steel.
