Carbitool TC2 Router Collet Reducer — 1/2″ to 3/8″
Part No: TC2 | Barcode: 9314350002258
Carbitool TC2 is a precision-ground straight reducing collet that lets a 1/2″ router collet hold a 3/8″ (9.53mm) shank router bit. Turn your 1/2″ plunge or fixed-base router into a versatile tool for smaller-shank bits without swapping collet nuts — a must-have for routers with 1/2″ collets that also need to run imperial small-shank tooling.

Key Features & Benefits
- Straight reducing collet design — seats inside a standard 1/2″ router collet and grips a 3/8″ (9.53mm) shank bit, giving your heavy-duty router access to the entire Carbitool small-shank range.
- Precision-ground OD and ID — hardened steel body ground to tight concentricity tolerance, keeping the bit running true and minimising run-out for clean, chatter-free cuts.
- Full-length contact — supports the shank over its full insertion depth, transmitting torque reliably and preventing slip under load.
- No nut or spindle change — drops into the existing 1/2″ collet. No need to swap collet assemblies to switch shank sizes.
- Carbitool quality — manufactured in Victoria to the same standard as the Carbitool router bit range, sized to match Carbitool shank tolerances exactly.
How to Use
Slide the TC2 reducer into your router’s 1/2″ collet just as you would a normal bit shank. Insert the 3/8″ (9.53mm) shank router bit into the reducer’s bore, leaving a small gap between the bit’s full shank depth and the bottom of the collet (never bottom out). Tighten the collet nut firmly. Always verify the bit is securely held by trying to rotate it by hand before powering on, and check again after the first cut. Remove the reducer when swapping back to a 1/2″-shank bit.
