Unique Bargains Square Hole Drill Bit 3/4-Inch High-Carbon Steel Hollow Chisel Mortise Power Tool for Woodworking

Feature - This square chisel mortiser achieves double the effect when used with a mortise and tenon machine, and square hole punching requires tools such as an electric drill and hammer.

Benefit - This tool reduces labor intensity for construction workers, speeds up construction, and lowers costs for installation, renovation, and decoration industries.

Operation - The square chisel mortiser combines a four-sided chisel with a central drill bit, where the bit clears most material and the chisel ensures straight and clean edges.

Application - This square hole drill is ideal for drilling square holes in wood with a mortising machine or attachment, and fits all mortising machines and drill press attachments for woodworking projects.

Note - Install directly in a square hole machine for best results, but if using a bench drill or electric drill, follow the operation method strictly to avoid only producing round holes.
