Amana Countersink Drill Bit 1/2 x 60mm gives drilling and countersinking in one step, which speeds up boring-machine work and helps keep hole alignment consistent from part to part. This Amana Tool countersink is identified as Manufacturer Part 55642, so matching it to drawings or existing tooling is straightforward in a professional shop. The 1/2 inch diameter cutting head forms the countersink size, creating a repeatable seat where matching fasteners or fittings sit flush in the workpiece. The 5 mm OD drilling portion sets the pilot hole size, so a 5 mm element locates accurately without slop. A 60 mm overall length allows the bit to work in standard boring-machine setups that expect this length, helping avoid constant spindle height changes. The 45 degree angle on the countersink shape produces a defined, uniform chamfer at the hole entrance that looks clean across production runs.
The 10 mm shank diameter on the Amana Countersink Drill Bit 1/2 x 60mm fits boring-machine spindles designed around that shank size, so the tool locks in securely for repeatable runs. Its 60 mm overall length means the cutting edges sit at a predictable distance from the spindle nose, making depth setting straightforward when repeating patterns across cabinet parts. Because it drills and countersinks in one step, the bit can stay in one spindle where both operations are needed, which helps keep multi-spindle heads organized. The 45 degree countersink angle and 1/2 inch head diameter remain fixed relative to the 5 mm OD drill, so once depth is dialed in, matching seats form consistently across a job.
The SAP description "COUNTERSINK, BORING MACHINE, 5MM OD" identifies this bit as intended for boring machines, so it drops naturally into line-boring or point-to-point style workflows that rely on 10 mm shank tooling. The 5 mm OD portion guides the drill path, which suits layouts using 5 mm-based hardware or fittings where positional accuracy keeps rows straight. Its 1/2 inch diameter countersink region forms a broader seat surrounding the 5 mm pilot, creating a defined shoulder around the hole where a mating component can bear on the surface. With a 60 mm overall length, the bit works within machine heads expecting that dimension, so operators can keep common depth settings when swapping between similar Amana Tool bits. The 45 degree angle on the countersink shape also mirrors a familiar chamfer geometry, so visual results are predictable.
The integrated drills and countersinks in one step function means the pilot and countersink are formed in a single plunge, which locks the alignment between the pilot hole and the chamfer every time. That combined action reduces opportunities for mismatch that can occur when a separate drill and countersink are used in different passes. The 10 mm shank diameter gives the tool a solid clamping surface in the spindle, which supports smoother rotation and helps hold the 5 mm OD drill portion on center. Because the overall length is 60 mm, jigs and stops referencing that dimension stay valid between replacements of the same 55642 part number. The 1/2 inch diameter countersink head works together with the 45 degree profile to spread contact over a defined ring around the pilot, which can help distribute bearing forces at the joint interface.
The Amana Countersink Drill Bit 1/2 x 60mm is described as a countersink for boring machine use, so it is intended for boring-machine drilling and countersinking tasks.
The Amana Countersink Drill Bit 1/2 x 60mm forms the pilot and countersink in a single plunge, which keeps both features aligned and reduces separate drilling passes.
The 5 mm OD on the Amana Countersink Drill Bit 1/2 x 60mm sets the pilot hole size, supporting layouts that rely on 5 mm components or locating elements.
The 10 mm shank diameter on the Amana Countersink Drill Bit 1/2 x 60mm matches boring-machine collets built for that size, promoting secure spindle clamping.
The 45 degree angle on the Amana Countersink Drill Bit 1/2 x 60mm shapes the countersink chamfer, influencing the appearance and bearing profile around the hole.
The 60 mm overall length on the Amana Countersink Drill Bit 1/2 x 60mm positions the cutting edges at a predictable distance from the spindle, helping maintain consistent boring depths.
The Amana Countersink Drill Bit 1/2 x 60mm, identified as Amana Tool part 55642, ties a 5 mm OD pilot with a 1/2 inch, 45 degree countersink on a 10 mm shank and 60 mm overall length, giving boring-machine users a clearly defined geometry. That combination allows the same tool to drill and countersink in one step, which supports efficient cabinet, fixture, or system-based layouts built around 5 mm sizing. For shops standardizing on 10 mm shank tooling and 60 mm length, this countersink bit aligns smoothly with existing boring-machine setups. Add this dedicated boring-machine countersink to keep pilot and chamfer operations tied together in a single, repeatable tool.
