15mm x 57mm brad point boring bit gives a 15mm diameter cut with a 57mm long drilling body, so cabinet and fixture holes can be bored to full depth while the flutes still clear chips for smoother drilling. The left hand design means this bit is built to rotate counterclockwise, which matches left hand boring spindles and keeps the cutting edges working in the correct direction. The brad point cutting geometry centers the bit as it starts, helping the point locate accurately before the outer cutting spurs engage, which supports clean hole entry on cabinet-grade panels. As an Amana Tool boring bit, it is purpose-built for woodworking setups that call for precise line boring or hinge-boring style holes at this diameter.
The 10mm shank configuration is intended for boring machines that accept this shank diameter, so the bit can be clamped in the spindle and run at the needed height for line boring or pattern drilling. The left hand, counterclockwise rotation requirement lines up with left hand spindles, so when the spindle turns the cutting edges enter the material with the proper shearing action. The 15mm cut size and 57mm length then work together to reach required depths while maintaining the same hole diameter across a sequence of bores. This boring bit is not for use in portable drills or routers, so its role stays on stationary machines and drill presses where the correct spindle and holding method are available.
The boring bit, 15mm lefthand design is suited to woodworking boring machines that run counterclockwise, so it matches the spindle direction and avoids reverse cutting. In these machines, the 10mm shank seats into the spindle or chuck sized for that diameter, creating a solid connection for repeated cycles. The 15mm x 57mm brad point boring bit dimension supports applications where a 15mm hole is required through or deep into cabinet components, fixture panels, or similar assemblies that are processed on line boring or dedicated boring equipment. When a drill press is equipped with the correct 3/8 inch shank version of this bit style, the same 15mm hole and brad point centering approach can be used on a single-spindle station for jigs, templates, or one-off parts that share the same diameter requirement.
The 15mm lefthand label indicates that the bit is meant to rotate counterclockwise, which keeps the cutting lips and spurs moving forward into the cut on left hand spindles rather than fighting the feed direction. On boring machines equipped this way, that rotation alignment supports smoother boring and helps reduce chatter as the 57mm long cutting body advances through the material. The brad point style tip centers the bit before the full 15mm circumference engages, which helps the hole start exactly where the setup locates the point, supporting accurate spacing when panels are indexed on fences or stops. Because this boring bit is specified for boring machines with a 10mm shank and for drill presses with a 3/8 inch shank version, its geometry is focused on fixed-station drilling, which supports consistent depth control and repeatable positioning in woodworking production.
The 15mm x 57mm brad point boring bit bores a 15mm diameter hole with a 57mm cutting length, so it can reach deeper into workpieces while holding the same hole size.
The boring bit, 15mm lefthand is designed to rotate counterclockwise on lefthand spindles, so its cutting edges work with the spindle direction for smoother cutting.
The 10mm shank is intended for boring machines built for that shank diameter, allowing the bit to clamp securely in the correct size spindle or holder.
The boring bit style is intended for boring machines with a 10mm shank and drill presses using a 3/8 inch shank version, keeping it on fixed-station equipment.
The 15mm x 57mm brad point boring bit is specified for boring machines and drill presses, so its design focuses on rigid setups rather than handheld drilling.
Amana Tool 301015 identifies this specific 15mm lefthand brad point boring bit, helping match the same diameter, length, and rotation style in future orders.
This 15mm x 57mm brad point boring bit from Amana Tool offers a defined 15mm hole size, a 57mm drilling length, and a lefthand, counterclockwise rotation suited to matching lefthand boring spindles. The 10mm shank design serves boring machines set up around that shank diameter, while the drill press suitability connects this style to fixed-column equipment using the appropriate shank. For cabinet, fixture, or panel projects that rely on stationary boring rather than handheld drilling, this boring bit provides a clearly specified diameter and rotation direction ready to integrate into those machines.
