Bosch RA1128 8-Piece Quick-Change Router Template Guide Bushing Set The Bosch RA1128 8-piece router template guide set guides woodworking routers along custom jigs, dovetail fixtures, and mortise templates to execute repeatable, clean cuts across hardwoods, softwoods, and composite cabinetry materials. Engineered with the patented RA1126 quick-change adapter, this precision metal bushing kit enables instantaneous tool-free guide swaps without requiring baseplate disassembly. Outfitted with six precision-machined guide bushings—including small and large dovetail profiles, dual radius hinge mortising guides, and two general-purpose template guides—plus the RA1100 threaded guide interface that accepts Porter-Cable® style 1-3/8" counter-bore bushings, it equips cabinetmakers, finish carpenters, and custom joinery woodworkers with broad template routing versatility across Bosch palm and mid-size routers. Best Used For: Dovetail Jig and Box Joint Routing: Guiding straight and spiral router bits cleanly along commercial dovetail jigs for precision drawer box assembly and casework joinery. Cabinet Door and Entry Hinge Mortising: Cutting precise, tearout-free mortises for 1/4-inch and 5/8-inch radius door hinges using dedicated template fixtures. Custom Pattern and Lettering Sign Routing: Tracking intricate wood templates, inlay patterns, and CNC-cut acrylic routing guides with high concentric precision. Key Performance & Safety Features Tool-Free Quick-Change Adapter: Patented RA1126 spring-loaded adapter mechanism allows rapid, one-click insertion and removal of template guides without hand tools.

Expanded Threaded Guide Interface: RA1100 adapter ring accommodates standard Porter-Cable® and universal threaded template guides sized for 1-3/8" counter-bores.
