5mm brad point boring bit gives you a dedicated cutter sized for precise 5mm bores, so line-boring and shelf-pin drilling stay consistent across multiple workpieces. The brad point geometry starts the hole accurately, which helps reduce wandering when you are repeating the same pattern along long cabinet sides or rails. The 70mm long design provides working reach suited to typical cabinet components, so you can drill through standard stock while maintaining a solid grip in the chuck. Branded as Amana Tool, the bit reflects a woodworking-focused design intent, which supports use in shop environments where repeat jobs demand dependable performance. As a boring bit in the Bits, Blades and Cutters category, it is built for machine drilling rather than handheld work, which aligns it with production setups and drill press operations on furniture and cabinetry components.
This 5mm x 70mm brad point boring bit is designed for boring machines with a 10mm shank interface, so it fits directly into chucks or collets sized for 10mm tooling in those machines. The same product line is also described for use in drill presses with a 3/8 inch shank, aligning with typical drill press chuck capacities in many woodworking shops. The left hand rotation is intended to run counterclockwise, so it pairs with spindles or heads configured for that direction rather than standard clockwise spindles. The product description states that it is not for use in portable drills or routers, which keeps the bit in fixed-machine applications where the spindle alignment and feed path remain controlled throughout the cut.
The 5mm brad point boring bit sits in the Bits, Blades and Cutters - Boring Bits category, so it is geared toward drilling accurate holes in woodworking and cabinet components rather than general construction tasks. As a 5mm diameter cutter, it aligns with 5mm system layouts commonly used in cabinet lines, casework, and shelf support patterns, giving you an option that matches metric hardware expectations. The 70mm long format supports boring through typical cabinet sides, shelves, and stretchers while leaving enough shank engagement in the spindle, which is important when fixtures or fences raise the workpiece off the machine table. In boring machines that accept a 10mm shank, this bit works as one element of a multi-spindle or single-head setup for repetitive drilling, helping you maintain registration from part to part. When used on a drill press from the same product family, it allows controlled vertical drilling into fixture-held parts, which suits furniture components and small-batch cabinet runs.
The left hand, counterclockwise rotation of this boring bit ties directly to machines built or configured for that direction, which matters when you are matching an existing line-boring head or specialized drilling station. Running a bit in its intended direction helps the brad point and cutting spurs engage the material the way they were ground to cut, supporting smoother entry and improved hole quality. The dedicated 10mm shank specification for boring machines locks the bit into tooling systems sized for that diameter, which reduces play at the spindle and supports consistent hole alignment over long production runs. In a drill press configured for the matching shank size from the described product line, the fixed head and table geometry hold the bit perpendicular to the work, so the brad point can do its job of starting cleanly at marked locations. Because the product description states that it is not for use in portable drills or routers, the bit stays in stationary machines where feed, angle, and speed remain stable, supporting repeatable results on cabinet parts and furniture components drilled to metric patterns.
The 5mm size indicates the hole diameter this Amana Tool bit is designed to bore, which aligns with metric 5mm layouts on cabinet and furniture components.
The left hand design means the bit runs counterclockwise, so it is suited to boring machines or drill setups configured for that spindle direction during drilling operations.
The bit has a 10mm shank dimension called out for boring machines, which matches common line-boring heads used in cabinet and furniture production environments.
The web description notes use with drill presses in the same product family, where the shank fits a 3/8 inch chuck and the fixed head controls alignment while drilling.
The description specifies that portable drills and routers are not the intended tools, focusing this bit on fixed boring machines and drill presses for controlled feed and alignment.
The 70mm length provides reach for typical cabinet sides and shelves while keeping enough shank engaged in the spindle, which supports stable, straight bores during production drilling.
This 5mm x 70mm Amana Tool brad point boring bit, Manufacturer Part # 304005, is built for counterclockwise, left hand rotation in boring machines with a 10mm shank interface and drill presses from the same product line. Its brad point cutting geometry and metric sizing support accurate 5mm holes across cabinet and furniture components. When your workflow depends on fixed machines for repeatable drilling to metric layouts, this dedicated boring bit offers a focused option sized and configured for that role.
