8mm x 70mm through-hole boring bit delivers an 8mm diameter cut over a 70mm boring length, so cabinet and fixture holes stay consistent from part to part on production setups. The left hand design means the tool is built to rotate counter clockwise, which matches left hand spindles on many dedicated boring machines used in woodworking shops. As a boring bit from Amana Tool, it is positioned for professional cabinet, furniture, and fixture work where repeatable hole sizing is critical. The bit is designed for blind hole drilling for European style concealed hinges, which lets you prepare hinge cup and related holes in the same drilling workflow. It is also designed for RTA fittings and 32mm systems, so it supports line-boring style layouts used in frameless cabinet construction and adjustable shelf patterns.
The boring bit is designed for use in boring machines with a 10 mm shank, so it fits spindles sized to accept 10 mm tool holders common to multi-spindle and line-boring equipment. It is also designed for drill presses with a 3/8" shank, which ties the tool directly to typical drill press chucks used in many woodworking shops. The manufacturer states it is not for use in portable drills or routers, which keeps the tool in rigid, column-guided setups where feed is controlled by the machine rather than by hand movement.
The boring bit is designed for blind hole drilling for European style concealed hinges, so it supports the hinge layouts used on many modern cabinet doors where hardware is hidden inside the case. Because it also serves RTA fittings, the same 8mm x 70mm geometry can be applied when preparing panels for ready-to-assemble connections in cabinet and furniture components. Design intent for 32mm systems ties the bit to standardized hole spacing used in frameless cabinets and adjustable shelving, allowing the same bit to handle line-boring runs and related hardware positions. This combination of European hinges, RTA fittings, and 32mm systems means one dedicated boring tool addresses several common cabinet construction patterns in woodworking production.
The left hand construction is built for rotation counter clockwise, aligning with left hand spindles on boring equipment so the cutting edges engage the work as intended. Using a boring machine with a 10 mm shank connection or a drill press with a 3/8" shank places the bit in rigid, guided columns, so holes follow the machine travel for straight, square bores. The explicit direction that the tool is not for portable drills or routers keeps it tied to machines designed for boring operations, which supports cleaner entry and exit as stock is fed at controlled rates. In practice, this alignment between left hand rotation, fixed machine mounting, and purpose-built drilling applications helps maintain hole accuracy across runs of hinge, fitting, and system holes.
The 8mm x 70mm through-hole boring bit produces an 8mm diameter bore, matching hardware and drilling layouts that specify an 8mm hole size in cabinet and furniture construction.
The left hand design rotates counter clockwise, so the bit is suited to left hand boring machine spindles, keeping cutting forces aligned with the machine drive direction.
The boring bit is designed for blind hole drilling for European style concealed hinges, supporting the hinge-related bores required on cabinet doors and cases using that hardware.
The boring bit is designed for 32mm systems, so it fits line-boring style layouts where hole spacing and diameter follow that standardized cabinet construction pattern.
The boring bit is designed for boring machines using a 10 mm shank and for drill presses using a 3/8" shank, aligning with common spindle and chuck sizes in woodworking shops.
The boring bit is specified as not for use in portable drills or routers, so it remains dedicated to stable boring machines and drill presses for guided, column-based drilling.
The Amana Tool 8mm x 70mm through-hole boring bit, left hand, brings an 8mm diameter, 70mm length, and counter clockwise rotation together for hinge, RTA fitting, and 32mm system work. With options for boring machines using a 10 mm shank and drill presses using a 3/8" shank, it integrates into fixed drilling stations already present in many woodworking shops. Selecting this 414008 boring bit aligns hole size, rotation direction, and shank style around a single dedicated tool for European style concealed hinges, RTA fittings, and 32mm cabinet systems.
