manufacturer of CCW/LH left Hand face driver pins for Left-hand helical groove & leadscrew machining! supplier of counterclockwise CW drive pins in face drivers for Back boring & reverse boring operation.

Left-hand face driver for twin-spindle centers. Carbide-tipped driving components for reverse boring, left-hand thread machining, and CCW rotation. Replaceable tips for Riten-style holders

For counterclockwise (CCW) spindles on twin-spindle machining centers and multitasking machines, the left-hand (LH) face driver delivers reliable torque transfer through hardened carbide-tipped driving components. These offset-style elements are designed to engage the workpiece end face during reverse boring and left-hand thread cutting operations.

Available for sub-spindle synchronization, the LH face driver features replaceable carbide tips that withstand high shock loads on forged or uneven surfaces. The driving components — offered in 3, 4, 6, or 8 configurations — compensate for workpiece end face irregularities up to 2mm.

Compatible with twin-spindle CNC lathes and multitasking centers (e.g., Mazak, DMG MORI, Okuma). CCW rotation models are stocked for immediate delivery. For left-hand thread machining or reverse boring applications, select the LH series with 90° or 60° carbide tips.
