Pocket Cutter & Screw Inserter

Pockets with Screws… DELIVERED 

Castle’s CSI-1.5 D Pocket Cutter/Screw Inserter saves time, reduces waste, and eliminates non-value-added labor and screw-handling motion trauma for high-production cabinet joinery.

By using patented Screw-in-Pocket (SIP) technology CSI-1.5 D cuts Castle’s distinctive screw pocket, drills a low angle pilot hole AND inserts a flush, stackable screw in 1.5 seconds. CSI-1.5 D provides faster production time by eliminating screw handling at assembly.

Using the Castle CSI Pocket Cutter/Screw Inserter can cut your assembly time nearly in half!

“We noticed an immediate impact on our production assembly in our finished products by 30%. We eliminated the inefficiencies of having the employee worry about inserting screws into panels and allowed them to concentrate on producing completed products. Another feature to note is we eliminated any employee using a wrong length screw during assembly since now all the panels are coming with the appropriate length screws pre-inserted. This new change in our company had the doubts of the shop floor in the beginning but after a solid month of utilizing the CSI machine we couldn’t imagine building our products without it.”

“The CSI has been a real game changer for us. We have been able to up production, without adding people.”

“The CSI from Castle has made a big difference in high-volume pocket hole work for us. We use pocket hole joinery in many applications and have several Castle machines. We build certain products that use a large number of pocket hole joints. The CSI literally eliminates one whole person from that assembly process. Also – Castle has always provided quality equipment that rarely needs service, but they have been very responsive with service and support whenever we have needed it. We appreciate Castle as a supplier and have been very happy with the CSI in particular.”
