25/64 x 2-7/8 carbide tipped countersink bit is a dedicated cutting tool for forming screw head seats in wood, plastic, and non-ferrous materials, so installers and fabricators can prep fastener holes in one controlled operation. This Amana Tool cutter is classified as a countersink in the bits, blades and cutters family, giving it a focused role whenever flat or tapered screw heads must sit properly. The carbide tipped cutting edges are engineered to deliver chip-free hole edges in these materials, which helps keep surrounding surfaces clean and reduces touch-up work around visible fasteners. With an overall length of 2-7/8 inch and a 25/64 inch cutting profile, it supports consistent screw head recess dimensions across repeated holes on cabinetry, fixtures, or jigs where appearance and alignment matter.
This countersink uses a 5/16 inch shank, giving drills and drill presses a solid gripping diameter for secure chucking during operation. That shank size supports stable rotation, which helps the 2-flute integral design maintain the advertised concentric and precise cut around a pre-drilled pilot hole. By pairing the integral 2-flute layout with carbide tipped cutting edges, the bit is set up to track accurately in wood, plastic, and non-ferrous materials while forming the 25/64 inch screw head recess. That combination of 5/16 shank support and concentric cutting geometry is valuable when producing consistent countersinks across multiple parts, face frames, or fixture components where fastener alignment contributes to overall fit.
This Amana Tool countersink is described for use in wood, plastic, and non-ferrous materials, so it fits common shop and jobsite tasks across cabinetry, casework, fixtures, and light metal trim using these substrates. The CT COUNTERSINK, NO8 SCREW designation ties the bit to No. 8 screw head seating, which is a typical fastener size in woodworking and related assembly, helping installers match their fasteners to the formed recess. The 25/64 inch cutting profile is configured to shape the screw head seat while working with a separate pilot hole, giving tradespeople a defined geometry for repeatable fastening across ganged parts or production runs. Because it is part of the countersinks product class, it focuses on creating that head recess rather than drilling through-holes, supporting a two-step drilling and countersinking workflow.
The 2-flute integral design is specified to provide consistent, precise, and concentric results every time, which supports uniform screw head seating and helps limit wandering that could shift a fastener off layout lines. Carbide tipped cutting edges are engineered to produce chip-free hole edges, so the transition around the countersunk area in wood, plastic, and non-ferrous materials stays clean, which is important on exposed faces or edges. The stated longer lifespan compared to steel countersinks means the cutting geometry remains effective over more holes, helping maintain repeatable results on larger projects without frequent tool changes. With a 2-7/8 inch overall length and 5/16 inch shank, the bit provides a compact yet stable form factor, which works well in drills or drill presses where controlled feed and steady rotation are needed for identical countersinks.
The Amana Tool 55206 countersink is described for wood, plastic, and non-ferrous materials, so it can be used across those common substrates when forming screw head recesses.
The 2-flute integral design is specified to ensure consistent, precise, and concentric results, supporting uniform screw head seating and helping maintain fastener alignment across repeated holes.
This carbide tipped countersink delivers chip-free hole edges and offers a significantly longer lifespan compared to steel countersinks, supporting more consistent performance over extended use.
The SAP description identifies it as CT COUNTERSINK, NO8 SCREW, indicating that its countersink profile is configured around seating No. 8 screw heads.
The bit has a 25/64 inch cutting profile, a 2-7/8 inch overall length, and a 5/16 inch shank, supporting stable chucking and a defined screw head recess size.
The carbide tipped cutting edges are designed to deliver chip-free hole edges, helping preserve clean surfaces around the screw head seat on visible workpieces.
The 25/64 x 2-7/8 carbide tipped countersink bit from Amana Tool combines a 5/16 inch shank, 2-flute integral design, and carbide tipped cutting edges to create concentric, chip-free screw head recesses. Its CT COUNTERSINK, NO8 SCREW designation links the geometry to No. 8 screw heads in wood, plastic, and non-ferrous materials. For installers and shops needing repeatable, clean countersinks instead of rough, oversized recesses, this dedicated countersink from Wurth Baer Supply offers a focused solution for preparing fastening points.
