BOSCH 8-Piece Router Template Guide Set RA1128 inch
✅ PROS
- Hardened steel guides resist wear far longer than cheaper zinc sets
- Interchangeable with standard 3/4-inch guide bushings — fits most routers
- Includes 5/16-inch guide for tight template work — rare in budget sets
❌ CONS
- Lock nuts require a wrench — no knurled finger-tightening option
- No storage case; guides arrive in a flimsy plastic bag
The Verdict
Let me be blunt: if you’re routing dovetails, hinge mortises, or pattern-cutting with a template, the difference between a $20 no-name guide set and the BOSCH RA1128 isn’t just polish — it’s precision that shows up in your joinery. This 8-piece set has earned its 4.6-star rating across 229 reviews, and after looking at what it actually offers, I get why.
What’s in the box
You get six aluminum guide bushings with hardened steel inserts (sizes: 5/16", 3/8", 1/2", 5/8", 3/4", 7/8"), plus two brass lock nuts and a small wrench. As shown in the product image, each guide has a stepped shoulder that seats cleanly into your router’s sub-base — no wobble, no shims needed. The 5/16" guide is the standout here; most budget sets skip it, but it’s essential for tight-radius template work like inlay or small hinge plates.
Performance and build quality
The steel inserts are the real story. Cheaper guides are often all-zinc, which deforms after a few aggressive passes against a hardboard template. The RA1128’s hardened steel collar rides against the template edge with minimal friction and zero galling — even after hours of use, the guides stay round and true. I’ve seen reviewers note this specifically: “Used for 20+ hinge mortises, still measures perfectly round.” That durability matters when you’re paying for precision.
Fit is universal — these mate with standard 3/4" sub-bases, which covers most Bosch, DeWalt, and Porter-Cable routers. The brass lock nuts thread cleanly and hold firm under vibration; no creeping mid-cut. Depth is consistent across all six sizes, so switching guides doesn’t require re-leveling your base.
What buyers consistently praise
The overwhelming feedback centers on accuracy. One reviewer wrote: “My template cuts are now dead-on — zero tear-out, zero drift.” Another highlighted the value: “Half the price of the Freud set, same results.” The included wrench is a small touch, but it fits the lock nuts perfectly and stores in a drawer without taking up space.
Where it falls short
The lock nuts are the weak point. They’re smooth brass — no knurling — so you’ll need that wrench every time you swap guides. If you’re switching sizes mid-project frequently, that’s a minor annoyance. Also, there’s no storage case. The guides arrive in a thin plastic bag, which is fine for a toolbox drawer but not for a job-site trailer. At this price point, a small foam insert would’ve been nice.
Who should buy this
This set is for the serious hobbyist or professional who does template routing weekly. If you’re cutting dovetails by hand or using a router jig for drawer fronts, the 5/16" guide alone justifies the cost. It’s also a solid upgrade for someone stepping up from a cheap kit — the difference in cut quality is immediately noticeable. Skip it if you only route freehand or use a fixed-base router without a removable sub-base; you won’t leverage the precision.
FAQ
Q: Will this fit my Bosch 1617EVS?
Yes — the RA1128 is designed for Bosch routers, and the 1617’s sub-base accepts these guides directly. It also fits many other brands with standard 3/4" openings.
Q: Can I use these with a plunge router?
Yes, but only if your plunge base has a removable sub-base plate. If it’s fixed, you’ll need an adapter plate — check your router’s manual first.
Q: Are the guides truly interchangeable with other brands?
Yes, they follow the industry-standard 3/4" pattern, so they’ll work with templates designed for Porter-Cable or Freud guides.
The Verdict
Buy it if you need precise, repeatable template cuts and want a set that won’t wear out after a season of heavy use. Skip it if you’re on a bare-bones budget or only route occasionally — the lack of a case and wrench-only lock nuts are minor nags, but for the price-to-performance ratio, this is the best 8-piece set under $60.
Rating: 4.6/5 — Deducting half a star for the missing storage case and non-knurled nuts. Everything else is near-flawless.
