Hitachi 323295 23mm Wrench KM12SC KM12VC

The Hitachi 323295 is a 23mm wrench designed specifically for bit and collet changes on the Hitachi KM12SC and KM12VC routers. If you've misplaced the original wrench that came with your router or it's been damaged after years of use, this OEM replacement gets you back to smooth, confident collet changes. It's the kind of part you don't think about until you need it — and when you do, having the exact factory-spec wrench beats fumbling with an adjustable or an ill-fitting metric wrench from the drawer.

Build quality is straightforward and solid. The wrench is stamped steel, sized precisely to the collet nut geometry on both compatible models. It sits flat against the nut without play, which prevents rounding and gives you clean torque transfer when tightening or loosening. There's no cushioned grip or ergonomic shaping — it's a utilitarian tool that does one job and does it right. Worth noting: Hitachi Power Tools has rebranded to Metabo HPT, but the tooling and parts are identical, so this wrench works regardless of which name is stamped on your router.
