1/2 DIA SPRING COLLETS ER32 is a high precision CNC spring collet from Amana Tool designed for holding 1/2 inch tooling in ER32 style systems, so routers and CNC spindles can grip bits accurately during demanding woodworking cuts. This CO-182 collet is part of Amana Tool Corp high precision CNC spring collet line, giving installers and shop owners a dedicated option when they need consistent performance from ER style holders. The collet is inspected for quality and 100% accuracy, which supports repeatable results when changing tools across different jobs. A standard 0.0004 T.I.R. rating means the collet keeps runout tightly controlled, helping tools track true in the cut. By allowing reduced vibrations on tools and motors, it supports smoother cutting behavior that matters when profile quality and edge finish affect downstream sanding and assembly. The design also helps prolong the life of tools and electrospindles, which protects investment in cutting tools and machine heads over long production runs.
This Amana Tool CO-182 spring collet is specified as a 1/2 DIA SPRING COLLETS ER32, so it is intended for ER32 style systems where 1/2 inch shank tools are standard. The ER style interface allows the collet to seat inside corresponding high precision toolholders, creating a concentric grip that supports accurate routing paths. With a standard 0.0004 T.I.R., the collet keeps the cutting edge aligned closely to the programmed toolpath, which reduces the chance of oversized or out-of-square cuts caused by excessive runout. Because the collet is part of a high precision CNC lineup, it is aimed at applications where detailed profiling, joinery preparation, and template work benefit from stable toolholding. When used on routers and electrospindles, the reduced vibration characteristic of this spring collet helps cutting tools engage the material more smoothly, which can support better surface quality before finishing steps.
The Amana Tool CO-182 1/2 DIA SPRING COLLETS ER32 is suited to CNC and router setups that rely on high precision spring collets in ER style holders. Its 1/2 inch diameter designation aligns with widely used shank sizes for straight bits, profile cutters, and many solid-carbide tools, so it fits naturally into workflows that standardize on 1/2 inch tooling. Because the collet is inspected for quality and 100% accuracy, it supports shops that run multiple machines or shift tooling between stations while expecting consistent alignment. The standard 0.0004 T.I.R. rating gives operators a way to control runout at the tool, which helps when tight-fitting joinery, hardware recesses, or nested CNC parts rely on predictable dimensions. When mounted in high precision toolholders on routers or electrospindles, the collet helps reduce tool and motor vibrations, which can support smoother edges on routed profiles and reduce stress transmitted into the spindle bearings.
The high precision design of this ER32 CNC spring collet directly affects how well cutting tools perform over time. By holding tooling within a standard 0.0004 T.I.R., the collet keeps the cutting edges tracing a more accurate circle, which improves hole location, slot width, and edge geometry on repeated passes. Reduced vibration on tools and motors means cutting edges contact the material more consistently instead of chattering, which helps prolong the life of tools by avoiding unnecessary impact on the cutting edges. The same reduction in vibration also benefits electrospindles, since smoother running reduces mechanical load during extended production runs. When this collet is used together with high precision toolholders, the system works as a matched toolholding solution where the collet, holder, and spindle each contribute to stable performance. That combination allows shops focused on cabinetry, architectural millwork, or production routing to maintain more predictable cutting behavior across batches, reducing the need for rework due to inconsistent cuts.
The Amana Tool CO-182 spring collet is specified as 1/2 DIA SPRING COLLETS ER32, so it is intended for holding 1/2 inch diameter tooling in an ER32 style collet system.
The CO-182 spring collet standard 0.0004 T.I.R. rating limits runout at the tool, which supports accurate cuts, cleaner profiles, and more consistent dimensions on repeated CNC or router operations.
The Amana Tool high precision CNC spring collet line, including CO-182, is inspected for quality and 100% accuracy, supporting consistent toolholding performance across different machines and tool changes.
This high precision spring collet is designed to reduce vibrations on tools and motors, which supports smoother cutting behavior and helps cutting edges engage material more consistently.
The CO-182 spring collet helps prolong the life of electrospindles by reducing vibration at the toolholder interface, which lessens mechanical stress on the spindle during operation.
The CO-182 high precision spring collet used with high precision toolholders forms a matched system that delivers the very best tool performance the router or CNC spindle can provide.
The Amana Tool 1/2 DIA SPRING COLLETS ER32 CO-182 gives shops a high precision CNC spring collet purpose-built for ER style toolholders and 1/2 inch tooling. Its standard 0.0004 T.I.R. rating, 100% accuracy inspection, and vibration-reducing design support accurate routing, better surface results, and longer tool and electrospindle life. For woodworking professionals relying on routers, CNC machines, and high precision toolholders, this ER32 collet helps align toolholding performance with the demands of tight-tolerance cabinet, millwork, and fixture production.
