Ovolaco™ Door Hinge Jig
Hinges That Sit Flush. Doors That Swing Right.
Clamps to the door edge and guides your router through a precise mortise — no crooked cuts, no stuck doors, no re-dos.
Eyeballing A Hinge Cut Always Ends The Same Way
You measure twice, chisel carefully, and the hinge still sits a hair off. Now the door rubs, doesn't latch, or leaves a gap at the top — and fixing it by hand risks ruining a door that cost real money.
Crooked mortise — door binds against the frame
Screw walks off-center — hinge shifts, hole strips
Wrong depth — hinge sits proud or sunken
Plastic guide flexes — cut drifts mid-way
No repeatability — every hinge is a fresh gamble
One bad cut — the whole door may need replacing
82% of Hinge-Mortising Hassles Start with Poor Positioning?
Try the Ovolaco Door Hinge Jig!
Repeated hinge mortises can be harder to position consistently when the cutting setup lacks a clear guide.
Our Solution:The hinge template and built-in depth gauge support more controlled positioning and precise mortise cutting.
Ordinary plastic hinge templates can be more prone to flexing or deformation during repeated installation work.
Our Solution:Precision-machined aluminum alloy provides strong deformation resistance for sturdier, more durable use.
Different hinge sizes and corner styles can make door-hinge routing more complicated than it needs to be.
Our Solution:Supports round hinges with 1/4" and 5/8" radius plus square-corner hinges with chisel support, covering sizes from 2-1/2" to 5".
Switching between separate positioning and driving tools can slow down a door-hinge installation project.
Our Solution:A self-centering hinge bit and dual-head screwdriver bit are included to reduce the need for additional tools.
A jig that clamps directly to the door edge removes the guesswork — the router follows the template, the bit finds dead-center on its own, and the hinge lands exactly where it should.
How It Works
Clamp
Secure the jig to the door edge with the tightening knobs.
Route
Guide your router through the template slots to cut the mortise.
Drill
Use the self-centering bit so every screw goes in straight.
Every Screw Lands Dead-Center
The included self-centering bit finds the middle of the screw hole automatically — no more stripped holes or hinges that shift after you tighten them down.
Solid Aluminum. Zero Flex.
Machined from 6061 aluminum alloy with an anodized finish — it stays rigid under the router, unlike plastic guides that bend and let the cut drift mid-way.
Everything Else It Solves
No more crooked, proud, or sunken hinges — clamps straight to the door edge so the mortise depth is exact, not eyeballed
Skip the trial-and-error setup — marked guides for 2-1/2" to 5" hinges, plus a built-in depth gauge for thick and thin hinges
One jig, every common hinge — works with 1/4" and 5/8" radius hinges, and square corners with a chisel
Protects the door finish — built-in silicone pads grip without scratching or marring the wood

We Got Answers!
Does it work on exterior doors?
It's built for doors up to 1-3/4" thick — the marked guides adjust across that range, so it covers most standard interior and exterior doors. Check your door's thickness before ordering.
Will the metal clamp scratch my painted door finish?
No. The clamping surfaces have built-in silicone padding, so the jig grips firmly without marking or scratching your door's finish.
Do I need a specific brand of router to use this?
No — it works with any standard handheld router. The jig's template slots guide the bit for you, so you just control the depth.
Is the material strong enough for repeated use?
Yes. It's machined from 6061 aluminum alloy with an anodized finish, so it stays rigid under router pressure instead of flexing or wearing out like plastic jigs.
Can I use it for different sizes of hinges?
Yes — the jig has marked guides for hinge lengths from 2-1/2" to 5", plus a built-in depth gauge, so you can switch sizes without manual measuring.
Can I use it for square-corner hinges?
Yes — it also supports 1/4" and 5/8" radius hinges. For square corners, you'll need a chisel (not included) to square them off after routing.
Is this for the door or the door frame?
The door edge only. It's not designed for cutting mortises on the jamb.
What's included in the box?
The jig itself, a router bit, a self-centering drill bit, and a double-ended screwdriver bit — everything you need to route and drill in one pass.
