Kreg Pocket-Hole Jig R3 Review
The clamp-on Kreg. No base, no built-in clamp, half the price of a K5 — and for repairs and site work that is the right trade.

Every pocket-hole jig Kreg sells drills the same joint. The difference between models is entirely about how the jig and the workpiece are held together, and that is what you are choosing when you pick the R3.
The R3 is the portable one. It is a small glass-reinforced nylon block with two hardened-steel drill guides at 7/8 in centres, and it clamps to the workpiece rather than the workpiece clamping into it. Dual positioning sliders set the guide height for material from 1/2 in to 1-1/2 in thick in 1/8 in increments, and the matching depth collar sets the stepped bit to suit.
That design makes it the only Kreg jig that can drill a pocket hole in something that cannot move. A face frame already screwed to a cabinet, a loose rail on a chair, a deck rail in place — the R3 goes to those. A K5 or a 720 with its integral clamp and base cannot, because the work has to come to the jig.
What is not in the box
There is no clamp. The kit includes the jig, a stepped drill bit, a 6 in square-drive driver bit, a depth collar, a clamp adapter pad, an Allen key, a sample of screws and plugs, and a carry case with the depth gauge moulded into it. The clamping is your problem — a Kreg face clamp is the natural answer, and a decent C-clamp or a quick bar clamp works.
This matters because holding the jig by hand while you drill is exactly how people end up with holes that break out of the face. The clamp adapter pad exists precisely so a face clamp can grip the jig properly; use it.
Where it slows down
Every hole is a separate setup: position, clamp, drill, unclamp, move. On a repair or a one-off that is fine. On a batch of twelve cabinet doors it is tedious enough that you will start eyeing the bench-mounted jigs, which is the honest reason Kreg still sells three tiers of jig.
The body is tough but it is plastic. Over-tightening a clamp onto it will bow the block slightly, and a bowed block means the guide is no longer square to the face. Snug, not crushed.
Who should buy it
Buy the R3 if your pocket-hole work is repairs, fixes and the occasional project, or if you want to find out whether pocket-hole joinery suits you before committing. Buy a K5-class jig instead if you are producing cabinets, where the integral clamp pays for itself in the first weekend.
What works
- It goes to the work instead of the work coming to it — clamped to a face frame already fixed to a wall, or to a chair rail you cannot unscrew, it does jobs a bench-mounted jig simply cannot
- Two hardened guides at 7/8 in centres give you a proper pair of holes in one setup, and the positioning sliders set thickness from 1/2 in to 1-1/2 in in 1/8 in steps
- Everything lives in the carry case, including the depth-collar gauge moulded into the lid, so a repair kit stays a repair kit
What doesn't
- There is no clamp included and no built-in one — you supply a face clamp or a C-clamp, and holding it by hand while drilling is how people get crooked holes
- For repeat production work it is genuinely slower than a K5 or a 720: every hole needs the jig repositioned and re-clamped
- The glass-reinforced nylon body flexes if you over-tighten a clamp on it, which throws the guide out of square with the face
