Castle CSI 1.5D Pocket Cutter and Screw Inserter

by Castle

With the patented Screw-In-Pocket (SIP) technology, CSI-1.5D cuts Castle’s distinctive, low-angle screw pocket, drills a low-angle pilot hole and inserts a flush screw - all in 1.5 seconds.

Castle’s CSI-1.5D Pocket Cutter/Screw Inserter Pocket cuts pockets and inserts screws in one step: pockets with screws, delivered! Our patented technology reduces assembly time by 50%. The CSI-1.5D produces stackable parts in faster production times, reduces waste, and eliminates non-value-added labor in high-capacity production joinery.
