SHOWA Mortising Chisel Bit 3/4" Shank

A mortising chisel bit with a 3/4" shank is a specialized tool used in hollow chisel mortisers or mortising attachments for drill presses. It cuts clean, square-sided holes (mortises) in wood, typically for joinery such as tenon-and-mortise joints. This type of bit combines a square hollow chisel with a central twist drill bit for efficient chip removal and precision.
