A 22 circlip grooving tool is an industrial-grade cutting solution designed to machine standard retaining ring seats.
In manufacturing, the designation "22" designates the width of the groove (2.2 mm) or a size 22 insert pocket.
These specialized tools are fabricated from high-rigidity tool steel and fitted with coated solid carbide inserts.
The insert geometries feature ultra-sharp, square edges with precise corner radii to prevent radius mismatch.
This ensures that the machined slot maintains a perfectly flat bottom and parallel walls for optimal component seating.
Without this exact geometry, circlips can fail to snap in securely, leading to catastrophic mechanical failure.
The tool functions via a direct radial plunge operation, driving straight into the axis of a rotating workpiece.
Depending on the component blueprint, these tools are divided into external holders and internal boring bars.
External variants machine the outer surfaces of drive shafts, axles, and pistons to lock bearings in place.
Internal variants enter pre-drilled bores to cut grooves inside gearboxes, hydraulic cylinders, and housings.
Modern indexable versions allow operators to quickly swap out worn carbide inserts without removing the master holder.
Advanced tool coatings like TiAlN are applied to these inserts to withstand extreme friction and high heat zones.
Chipbreaker geometries are also ground into the top face to tightly curl and break metal chips away from the slot.
This chip control prevents the groove from cloggING.
