1/4 x 57mm brad point boring bit defines this Amana Tool cutter as a dedicated boring bit sized for 1/4 inch holes and a 57mm overall length, giving woodworkers a consistent, known reach for repetitive line-boring and shelf-pin drilling jobs. The brad point design centers the cut as the bit engages, which helps the tip start exactly where laid out and supports cleaner hole entry on cabinet parts and panels. The bit is classified as a router bit within bits, blades and cutters, so it fits directly into a tooling lineup already focused on precise cutting tools for woodworking. The manufacturer part number 301007 uniquely identifies this specific left hand boring bit, which matters when matching replacement tooling or standardizing setups across multiple boring stations in a shop.
This Amana Tool 1/4 x 57mm brad point boring bit is designed for boring machines with a 10mm shank, so it fits directly into boring heads that accept standard 10mm tooling for cabinet and furniture drilling operations. The bit is also specified for drill presses with a 3/8 inch shank version, which means the same cutting profile can be applied on drill press setups when using that corresponding shank size. The left hand rotation defined for this tool means it is built to run counterclockwise, matching machines configured for that spindle direction so the cutting edges engage correctly. The manufacturer notes that this boring bit is not for use in portable drills or routers, which keeps it in fixed-station machines where feed, alignment, and spindle guidance support accurate, repeatable boring.
This 1/4 x 57mm brad point boring bit with a 10mm shank is specified for boring machines, placing it directly in line-boring stations and dedicated drilling machines commonly used in cabinet and casework production. In these machines, the 10mm shank dimension matters because it mates with tool holders engineered to grip that diameter, so the bit runs true in multi-spindle heads or single-spindle boring setups. The web description also identifies drill presses with a 3/8 inch shank option, tying this cutting geometry to stationary drill press work where a 3/8 inch held version is used for similar 1/4 inch holes. Because the brand is Amana Tool, the bit aligns with other Amana cutters already on many woodworking floors, supporting consistent performance across boring, routing, and drilling stations when a shop standardizes on that tooling family.
The left hand designation and counterclockwise rotation callout define how this brad point boring bit is meant to cut, so when it is used on a left hand boring spindle, the cutting edges sweep chips out in the intended direction and the tip tracks properly. The brad point configuration centers the bit as it starts, which helps the sharp center spur grab the layout point and guides the outer cutting lips to scribe the circle before the full diameter engages, supporting cleaner entry on cabinet sides, shelves, and rails. The 1/4 inch diameter paired with a 57mm length creates a compact, predictable tool length that suits repetitive boring patterns, reducing variation in hole depth when machines are set for that specific length. As an Amana Tool product with part number 301007, the bit can be specified precisely in shop tooling lists, which supports consistent replacement and uniform results across multiple boring machines using the same setup parameters.
This Amana Tool 1/4 x 57mm brad point boring bit is designed for boring machines with a 10mm shank and is also described for drill presses when using the 3/8 inch shank version.
The 301007 boring bit is left hand, so it is built to rotate counterclockwise on compatible spindles, aligning with machines configured for that direction so the cutting edges work as designed.
This brad point boring bit uses a centering tip that starts accurately on mark, which helps control entry and supports cleaner 1/4 inch holes in cabinet and woodworking components.
The 10mm shank is specified for boring machines, allowing the bit to seat properly in 10mm holders so it runs true in dedicated woodworking boring equipment.
This Amana Tool boring bit is described as not for use in portable drills or routers, so its role remains in fixed boring machines and drill presses where the spindle guides the cut.
Manufacturer part number 301007 identifies this specific 1/4 inch, 57mm long, left hand Amana Tool brad point boring bit, helping shops specify and reorder the exact cutter.
The Amana Tool 1/4 x 57mm brad point boring bit, left hand, matches woodworking operations that rely on 10mm shank tooling in boring machines and favor centered, brad point entry for 1/4 inch holes. Its counterclockwise rotation design fits left hand spindles, so installation into the correct machine type supports the intended cutting action and bore quality. With its defined 57mm length and part number 301007, this cutter fits well into standardized tooling lists where consistent boring dimensions and repeatable replacement are important on production cabinet and furniture lines.
