3/8 x 1-1/2 Keyhole Bit describes a router bit sized to cut a keyhole entry and slot, which creates a secure hanging or fastening point in cabinet joinery where a straight hole would not hold as positively. The Amana Tool brand identifies a professional-grade cutting tool line, which matters to installers who want consistent cutting behavior across multiple jobs and materials. This router bit belongs to the Bits, Blades and Cutters category under Cabinet Joinery, so it is built specifically for joinery-style cuts rather than general trimming, helping keep tool selection straightforward on a cabinet or woodworking bench. The product is defined as a Router Bit in the product class, which tells you it works in a router-driven workflow rather than in a drill or other machine, aligning with typical shop and onsite setups.
The web description states that you plunge to form the entry, which defines the first motion: lowering the router so the bit creates the round entry pocket that becomes the wider end of the keyhole. It then specifies that you advance the router to cut a short T-slot, describing the second motion where you move forward to form the narrow slot extending from the entry, creating the keyhole profile used in cabinet joinery. The note to use this bit in a handheld plunge router highlights the intended installation method, aligning the geometry with plunge capability so installers can start cuts inside the panel surface without predrilling.
The product is categorized under Cabinet Joinery, which places this 3/8 x 1-1/2 Keyhole Bit squarely in cabinet and woodworking projects where a concealed hanging or fastening point is needed rather than exposed hardware. The router bit class means it runs in a router, so it fits shop routers and handheld plunge routers typically used around cabinet boxes, panels, and similar parts. The 1/4 inch shank specification ties it to routers equipped with 1/4 inch collets, common on many trim and mid-size routers used for on-site cabinet work. Because the web description calls out use in a handheld plunge router, this bit suits situations where parts are already installed or too large for a table, letting the installer bring the tool to the work and form keyhole slots directly on walls, cabinet backs, or panels. In a cabinet joinery workflow, this combination supports flexible positioning of keyhole cuts wherever needed on the component.
The instruction to plunge to form the entry and then advance to cut a short T-slot defines a two-step motion that can be repeated slot after slot, giving installers a simple pattern to follow for consistent keyhole geometry. The 3/8 inch diameter fixed in the SAP description keeps the round portion of the keyhole the same on every cut, which matters when the same style of hanging or fastening point is used across a run of cabinets or fixtures. The 1-1/2 inch length in the product name allows enough engagement to create the entry and a short slot without excessive projection, helping control the router during plunges and advances. The 1-flute design gives a single cutting edge, which influences chip evacuation along the short T-slot so the cut tends to clear forward as the router moves, supporting a predictable feel. With the Amana Tool manufacturer part 45650 clearly assigned, shops can specify this exact keyhole profile in job standards so replacements match earlier work and reduce variation between installations.
