5mm x 57mm brad point boring bit is a dedicated boring tool sized for 5mm holes and built around a 57mm overall length, which supports accurate boring depths in woodworking operations. The brad point tip defines the hole center before the cutting edges engage, helping the bit track straight for precise location. This boring bit is identified as left hand, so it is intended for applications where a counterclockwise rotation is required. That handed rotation detail matters when matching the bit to a machine spindle that is set up for a specific direction. The bit is part of the Amana Tool line, so it sits in a range of tooling aimed at professional cutting and boring work. With this defined diameter, length, and hand, the bit helps standardize repetitive boring patterns in shop workflows.
This 5mm x 57mm brad point boring bit uses a 10mm shank for boring machines, so it installs into machine chucks or collets sized for a 10mm tool interface. That direct match between shank and holder reduces slippage and helps keep the bit running true during operation. The same product notes that drill presses are served with a 3/8 inch shank variant, so the boring-machine-focused 10mm shank version clearly targets fixed boring equipment. The bit is specifically described as not for use in portable drills or routers, indicating it is intended to run in stable, guided setups rather than hand-held tools. That limitation supports straighter bores and more controlled feed when working in production fixtures.
The Amana Tool 5mm x 57mm brad point boring bit, left hand, slots into boring machines that accept a 10mm shank, aligning with equipment built for fixed-position drilling. Left hand tools rotate counterclockwise, so this bit fits spindles or heads that are driven in that direction. That relationship between hand and spindle rotation is critical, because a left hand bit running on a counterclockwise spindle will cut properly rather than rub. Boring machines benefit from the defined 5mm diameter because it supports standard hole layouts in cabinet and furniture construction. The 57mm overall length gives the operator a known projection to work with in multi-head setups, keeping different stations aligned around the same reach. In drill press environments, the web description notes that drill presses use a 3/8 inch shank, highlighting how this configuration is focused on the 10mm shank boring machine side of that tooling family.
The brad point geometry establishes a center point before the main cutting edges engage, which promotes clean entry and controlled tracking through the workpiece. That helps reduce wandering when boring closely spaced holes, a common requirement in cabinet lines. The left hand rotation specification ensures that on counterclockwise spindles the cutting edges engage the material as designed, which supports efficient chip removal and smoother hole walls. The 10mm shank gives a robust gripping surface in dedicated boring machine holders, enhancing torque transfer and alignment for multi-shift production. Identifying this bit as 5MM BRAD POINT, LH 57MM LONG in the SAP description and as manufacturer part 301005 simplifies specifying it in job travelers and tool lists, so the same cutting tool can be deployed across different machines. The note that right hand tools rotate clockwise and left hand tools rotate counterclockwise helps clarify tool selection when a shop runs both spindle types.
The 5mm x 57mm brad point boring bit is a left hand cutting tool with a 10mm shank, designed for boring precise 5mm holes in woodworking applications.
The left hand boring bit is intended for counterclockwise rotation, so on a matching spindle it cuts efficiently and supports proper chip evacuation during boring operations.
The 10mm shank is identified for boring machines, where this shank size matches dedicated holders and provides a stable interface during repetitive drilling cycles.
The web description notes that boring machines use a 10mm shank and drill presses use a 3/8 inch shank version, so this specific 10mm shank configuration targets boring machines.
The product description states Do not use in portable drills or routers, so it is aimed at fixed boring machines and drill press style setups.
The 301005 designation is the manufacturer part number for this 5mm brad point, left hand, 57mm long bit, helping shops reorder the same tool consistently.
The Amana Tool 5mm x 57mm brad point boring bit, left hand, aligns with boring machines that run counterclockwise spindles and accept a 10mm shank. Its defined 5mm diameter and brad point cutting geometry support accurate, repeatable hole locations in cabinet and furniture work. With the left hand rotation clearly specified and the 301005 part number tying it to a precise configuration, this bit fits shops standardizing on consistent boring tools. Add this dedicated 5mm boring bit when a counterclockwise spindle and 10mm shank interface are part of the production line.
