Amana 1/2" x 2-1/8" Carbide Tipped Countersink sets up a clean tapered hole sized for a #12 screw, so cabinet and woodworking jobs get a consistent seat for the fastener head. The 1/2 inch size and 2-1/8 inch length define the working profile, helping match this bit to drilling depth and clearance needs on site or in the shop. Carbide tipped construction focuses cutting action at the edge, supporting smooth countersinking in wood-related applications. As a countersink in the Countersinks product class, this tool forms the recess rather than acting as a general twist drill, so it targets finish quality around the screw head. The #12 screw designation ties the cutting geometry to that screw size, which matters when standardizing fasteners across repeated installations or production runs.
This Carbide Tipped Countersink Taper Bit for a #12 screw brings together the 1/2 inch sizing and 2-1/8 inch length to define how it engages the workpiece during drilling and countersinking. The 82 degree reference in the SAP description links the cutting profile to an 82 degree countersink angle, which aligns with that specified geometry for screw seating. As an Amana Tool countersink, it is built as a dedicated countersink rather than a multi-purpose bit, so its shape is tuned toward producing the taper and recess around the screw head. In cabinet or woodworking setups that standardize on #12 screws, this fixed geometry supports repeated, comparable results across multiple holes and parts.
This Amana 1/2" x 2-1/8" Carbide Tipped Countersink Taper Bit works in jobs where #12 screws are specified and a tapered countersunk seat is required. The 1/2 inch bit size gives installers a known dimension when choosing drills or drill press setups for cabinetry, casework, or related wood projects. Its 2-1/8 inch length defines how far the cutting profile extends, affecting suitability when drilling through thicker components or layered assemblies. Classified under Countersinks, the tool is applied when a recessed screw head is part of the design, rather than when a flat or pan head sits proud of the surface. The #12 screw designation guides fastener selection in builds that align screw size, pilot, and countersink for repeatable joints.
The SAP description highlights an 82 degree reference with a #12 screw focus, tying the cutting geometry of this countersink to that angle and screw size combination. For installers working around #12 screws, this alignment supports a seat that corresponds to an 82 degree style profile. The carbide tipped construction emphasizes edge retention at that shaped profile, helping maintain the same cutting action across multiple holes. The Amana Tool identity and the 55628 manufacturer part number link this bit to a defined design, which matters when shops want to repeat results by reordering the same countersink. By combining 1/2 inch sizing, 2-1/8 inch length, an 82 degree reference, and a #12 screw target, the bit establishes a predictable geometry that supports consistent countersunk joints in wood-related applications.
The Amana 1/2" x 2-1/8" Carbide Tipped Countersink Taper Bit is defined for a #12 screw, so its tapered hole and recess geometry are intended to work with that screw size.
The 82 degree notation in the description indicates the countersink angle profile this bit is designed around, which relates to how the screw head seats in the tapered recess.
The 1/2 inch dimension identifies the bit size, which matters when matching the countersink to drill chucks, guides, or setups that expect that diameter.
The 2-1/8 inch length states the working reach of the countersink, affecting how it operates in thicker stock or stacked parts during cabinet or woodworking projects.
The carbide tipped construction concentrates harder material at the cutting edges, supporting extended cutting performance during repeated countersinking in wood-related work.
This product is categorized under Countersinks within Bits, Blades and Cutters, so it is planned as a dedicated countersinking tool rather than a general-purpose drill bit.
The Amana 1/2" x 2-1/8" Carbide Tipped Countersink Taper Bit, tied to #12 screws and an 82 degree profile, offers a clearly defined geometry for forming screw seats in wood-based projects. The 1/2 inch size and 2-1/8 inch length specify how it fits into existing drilling setups. As an Amana Tool countersink in the Countersinks class, it focuses on shaping the recess around the screw head rather than general drilling. For projects built around #12 screws, this fixed combination of dimensions and angle supports consistent countersunk joints across repeated installations.
