Description

B27G covers auxiliary equipment, hand tools, and protective mechanisms used in wood and wood-like material processing operations. This includes accessory machines that support primary woodworking processes, specialized hand tools for shaping and finishing wood, and safety devices designed to prevent injury during wood machining operations. The classification encompasses both stationary auxiliary equipment mounted to primary machines and portable tools employed in woodworking, as well as guards, brakes, and control systems that enhance operator safety.

Scope Notes

Glossary: Auger Augers Wood augers are wood drills that have a screw to pull them into the wood, as a gimlet has, and a cutting lip that slices out the bottom of the hole. The auger bit (or drill) also has cutting spurs to cut a clean circle deeper than where the lips scrape out the wood Cutter block Cutter blocks Block for mounting cutters Gimlet Hand tool for drilling small holes without splitting the wood Kerf The groove or slit created by cutting a workpiece; an incision; the width of the groove made while cutting Mitre Angled cut, commonly 45 degrees Mitre joint mitre joints Joint made by bevelling each of two parts to be joined, often at a 45° angle, to form a corner, usually a 90° angle. The mitre joints can be made by sawing, planning, shearing or milling Shearing Cutting Spokeshaves Tool used to shape and smooth wooden rods and shafts such as wheel spokes and chair legs by shaving off small amounts of wood | Limiting references: Grinding tools Guide fences for timber in sawing machines Sawing tools Tools for slotting or mortising machines Tools for the manufacture of wood shavings, chips, powder, or the like | Application references: Other working of veneer or plywood specially adapted to veneer of plywood Machines or devices for making joints with tenon or like connections Machines for debarking or removing vestiges of branches from trees or logs
