1/4 x 70mm brad point boring bit is a left hand Amana Tool boring bit that cuts with a brad-point tip, so the center spur locates the hole before the cutting edges engage, helping installers start holes accurately on layout marks and reduce walking on hard surfaces. The left hand rotation matches machines that turn counterclockwise, which keeps chip flow and cut quality consistent with the spindle direction used in those setups. The 10mm shank interfaces with boring machines designed for 10mm-tool clamping, giving cabinet and fixture shops a direct fit where that spindle size is standard. The 1/4 inch cutting diameter matches common shelf and hardware hole layouts, which helps maintain consistent sizing across runs. The Amana Tool brand identifies the bit within existing tooling programs, making it straightforward to match this bit to catalogs, tooling lists, or machine presets built around Amana numbering.
The bit is specified for boring machines with a 10mm shank interface, so it fits chucks or collets designed around that size on dedicated boring equipment used in cabinet and woodworking production. It is also specified for drill presses when using a 3/8 inch shank setup, which connects the bit style to drill-press operations where that shank configuration is present. The product information states that it is not for use in portable drills or routers, which confines its role to stationary machines that provide fixed spindles and controlled feed, aligning the bit with equipment where consistent perpendicularity and depth setting are part of the workflow.
The 1/4 inch cutting size places this bit in tasks where a 1/4 inch bore is required, such as layouts that specify that hole diameter for woodworking or casework components. In boring machines set up with 10mm shank tooling, this bit fits tooling banks or single-spindle fixtures that accept 10mm-shank cutters, aligning with machines configured for that standard. When used in drill press applications that rely on the compatible shank setup, the bit can support vertical hole production where the workpiece is brought to the table instead of through a line borer. The left hand, counterclockwise rotation specification assigns this bit to spindles or machines that are designated to run left hand tooling, which helps shops pair the bit with the correct motor direction so the cutting edges engage the work in the intended orientation.
The brad point geometry, with its center spur, helps the bit establish a defined starting point before the outer cutting edges remove material, supporting accurate hole placement on layout marks in repetitive drilling work. The 70mm length works with machine setups designed around that projection, so once fence positions and depth stops are established for this length, operators can repeat the same bore depths without changing tooling geometry. The 10mm shank size gives a positive fit in boring machine spindles built for that dimension, which supports secure clamping and stable rotation during multi-part runs. The defined left hand rotation is important for machines with both left and right hand spindles, because matching this bit to counterclockwise rotation keeps the cutting lips engaging correctly, protecting surface quality at hole edges. The Amana Tool designation and 304007 number connect the tool directly to manufacturer data, helping shops document this specific bit in tool lists, maintenance schedules, and replacement planning for their boring stations.
The 1/4 x 70mm Amana Tool 304007 is a brad point boring bit, so it uses a center spur and cutting lips that support accurate, clean hole starting in woodworking and similar boring applications.
The left hand rotation means the bit is designed to turn counterclockwise, so it matches left hand spindles on boring machines, allowing the cutting edges to engage the material in the intended direction.
The brad point bit uses a 10mm shank for boring machines, which fits tooling systems designed around 10mm-clamping, giving a secure mount on compatible boring equipment.
The 304007 brad point bit is specified for drill presses when using a 3/8 inch shank setup, so it can serve vertical boring tasks on stationary drill press equipment matching that configuration.
The bit is described as not for use in portable drills or routers, so its role is focused on fixed boring machines and drill presses that provide stable, guided spindle motion.
The 1/4 inch diameter means the bit produces 1/4 inch holes, which supports layouts and jigs designed around that size when consistent hole diameters are important in repetitive drilling.
The 1/4 x 70mm Amana Tool brad point boring bit, left hand, 10mm shank, is configured for boring machines and drill presses that match its shank and rotation details, giving shops a defined option when they need 1/4 inch brad point holes under stationary, guided drilling conditions. For projects and production lines built around 10mm shank boring tools and counterclockwise spindles, this bit aligns with those requirements so installers and fabricators can match their equipment configuration with a clearly specified cutting tool.
