8mm x 70mm brad point boring bit is an Amana Tool left hand bit designed for woodworking setups that require an 8mm diameter hole with a defined brad point. The 70mm length supports deeper boring jobs where standard shorter bits are limiting, giving more reach in cabinets, panels, and similar workpieces. Its left hand rotation is built for machines that drive tools counterclockwise, matching specialized boring heads that are set up that way. The 10mm shank size fits boring machines designed for that shank, so the bit seats securely in properly matched chucks. As a brad point style bit, the center point starts the hole where the user lines it up, which helps limit wandering at the start of the cut and supports repeatable layout in production runs.
This Amana Tool brad point boring bit is set up for use in boring machines with a 10mm shank interface, so it fits those machines that accept that shank size. It is also suited to drill presses when a 3/8 inch shank version is used, which keeps it working in stationary equipment where the spindle runs true. The bit is left hand, and left hand tools rotate counterclockwise, aligning it with equipment designed to spin bits that way. The manufacturer states it is not for portable drills or routers, keeping it in rigid setups where clamped workpieces and guided quills support accurate boring.
This 8mm x 70mm brad point boring bit from Amana Tool is part of a boring bit line used in woodworking machinery where consistent hole size is critical. In boring machines with a 10mm shank spindle, the bit seats into the designated collet or chuck, allowing the machine to run multiple holes with repeatable spacing and depth. The 70mm overall length provides coverage for thicker panels, so cabinet sides and similar components can be bored through without changing to another diameter. Because right hand tools rotate clockwise and left hand tools rotate counterclockwise, this specific left hand bit works in stations or heads that are built to drive counterclockwise, keeping cutting direction synchronized across the machine setup.
The brad point design on this 8mm bit centers the cut where the point touches first, which supports accurate start location when drilling into finished faces or pre-marked layout lines. The left hand rotation spec means the flutes and cutting edges are oriented for counterclockwise motion, so when paired with compatible boring machines or drill presses, chip removal and cutting action follow the intended path. The 10mm shank dimension ties the bit directly to machines made for that shank, reducing play in the spindle interface, which helps hold hole size and alignment over repeated cycles. The manufacturer part number 304008 clearly identifies this combination of 8mm diameter, 70mm length, left hand rotation, and 10mm shank, helping buyers match existing tooling charts or job specs that call out this specific configuration.
The 8mm x 70mm brad point boring bit is designed for boring machines with a 10mm shank interface, so it fits into equipment built around that shank size for controlled, repeatable boring.
The left hand rotation means this bit runs counterclockwise, suiting boring machines or setups designed to spin tools that way, so cutting edges and chip flow work as intended.
The Amana Tool bit is specified for boring machines and drill presses, keeping it in rigid, guided spindles instead of handheld tools, which supports straighter, more controlled boring.
The bit cuts an 8mm diameter hole, and its 70mm length provides added reach for thicker workpieces, giving flexibility for deeper or through-hole boring tasks in woodworking stock.
The 10mm shank matches boring machines designed for that shank size, so the bit seats securely in the spindle, supporting accurate alignment and consistent hole placement during production runs.
The Amana Tool part number 304008 identifies this specific configuration: an 8mm diameter, 70mm long, left hand brad point boring bit with a 10mm shank for woodworking machinery use.
The Amana Tool 8mm x 70mm brad point boring bit, left hand, lines up with shops running boring machines or drill presses that accept 10mm shanks and counterclockwise rotation. When hole size, depth reach, and rotation direction must follow a defined tooling plan, its 8mm cutting diameter, 70mm length, and left hand design give a clear match to those requirements. For projects or production cells calling out Amana part 304008, this bit provides the defined geometry and machine interface needed for consistent boring performance.
