caption_attribution_description: English: A worker uses a specialized tool called a mortising machine to notch joints in timbers.
context_page_description: A mortiser or morticer is a specialized woodworking machine used to cut square or rectangular holes in a piece of lumber, such as a mortise in a mortise and tenon joint.
context_section_description: For cutting larger mortises such as those used in timber frame construction, chain mortisers are commonly used. A chain with cutters (similar to a chainsaw chain) rotating within a frame clamped to the work is successively plunged into the workpiece to mortise out the required volume.  The Makita 7104L is such a tool. These chains are made in varying widths, with numbers of chains in parallel. The teeth are often solid or tipped tungsten carbide. They are thus very expensive, sometimes as much as the rest of the mortiser.
