1/2 x 1 high precision steel router collet reducer 1/4 shank describes an Amana Tool reduction sleeve designed to let a 1/2 inch collet securely grip a 1/4 inch shank bit. This reduction bushing is an industrial high precision machined collet reduction sleeve, so the fit between collet and bit is carefully controlled for CNC and router work. The sleeve is produced with high quality steel, which gives the reducer a stable body under normal cutting forces and repeated bit changes. Because it enables collet sizes to be reduced to accept CNC and router bits with smaller shank sizes, it helps keep existing equipment useful when a smaller shank tool is needed. The manufacturer states that reducing the router collet with a sleeve is not a long term solution, so this reducer is best suited for situations where using a smaller shank bit is required while a dedicated 1/4 inch collet is not being used.
This reduction bushing 1/2 to 1/4 is sized so a 1/2 inch router collet clamps on the outer diameter while the 1/4 inch shank sits inside, which creates a firm interface for 1/4 inch bits in a larger collet. Because the piece is an industrial high precision machined collet reduction sleeve, the internal and external diameters are matched to common CNC and router collet and shank sizes, supporting a centered hold on the bit. The use of high quality steel in the sleeve means the gripping surfaces resist deformation under typical router collet tightening torque, which is important for maintaining bit alignment over time. The manufacturer notes that reducing the router collet with a sleeve is not a long term solution, so the reducer serves best when a 1/4 inch bit must be run in a 1/2 inch collet during normal work cycles.
The Amana Tool 1/2 x 1 high precision steel router collet reducer 1/4 shank is described as an industrial high precision machined collet reduction sleeve, so it is aimed at CNC and router setups handling regular production or serious project work. Because it enables collet sizes to be reduced to accept CNC and router bits with smaller shank sizes, it works where a machine is set up with a 1/2 inch collet but a 1/4 inch shank bit is required for the job. The reduction bushing 1/2 to 1/4 allows that smaller bit to be held by the existing collet, which is useful when changing to a smaller diameter tool is part of the cut sequence. Its high quality steel construction gives the sleeve a solid body for typical woodworking routing loads, aligning with the industrial positioning described by the manufacturer.
This reduction sleeve is described as high precision machined to limit the chance of run-out, which directly affects how smoothly a router or CNC bit tracks during cutting. When the collet and shank are closely fitted by a precision machined steel sleeve, the bit stays more concentric as it rotates, which helps reduce vibration and supports better edge finish on routed parts. The industrial high precision machined collet reduction sleeve design also helps maintain alignment when bits are swapped, since the internal bore is made to match 1/4 inch shank size rather than relying on a loose fit. The manufacturer states that reducing the router collet with a sleeve is not a long term solution and strongly recommends using the correct size collet for best results, which positions this RB-116 sleeve as a practical way to run 1/4 inch shank bits in a 1/2 inch collet when that configuration is needed.
The Amana Tool RB-116 is an industrial high precision machined collet reduction sleeve that lets a 1/2 inch collet hold 1/4 inch shank CNC and router bits for typical routing operations.
This collet reduction sleeve enables collet sizes to be reduced to accept CNC and router bits with smaller shank sizes, so a 1/2 inch collet can clamp standard 1/4 inch shank tools.
The RB-116 reduction sleeve is produced with high quality steel so the body stays stable under typical clamping forces, supporting consistent gripping and alignment during routing.
This industrial high precision machined collet reduction sleeve is made to limit the chance of run-out, helping the rotating bit stay centered for smoother cuts.
The manufacturer notes that reducing the router collet with a sleeve is not a long term solution and strongly recommends using the correct size collet for best results.
This reduction bushing 1/2 to 1/4 is most useful when a 1/2 inch router collet machine needs to run 1/4 inch shank CNC or router bits for a specific routing task.
The Amana Tool 1/2 x 1 high precision steel router collet reducer 1/4 shank offers an industrial high precision machined collet reduction sleeve that enables a 1/2 inch collet to run 1/4 inch shank CNC and router bits. Because the sleeve is produced with high quality steel and is made to limit the chance of run-out, it supports centered, stable bit rotation for many routing tasks. The manufacturer states that reducing the router collet with a sleeve is not a long term solution and strongly recommends using the correct size collet for best results, so this RB-116 bushing serves as a focused way to run smaller shank tools when a 1/2 inch collet setup is in place.
