Home improvement tool that speeds up hinge cup drilling while keeping results consistent. Confident and accurate fittings help reduce rework and frustration for DIYers and tradespeople. Is the GQGP Concealed Hinge Jig the right addition to your workshop toolkit?
⚡ At a Glance
- • Drilling Accuracy: Flat aluminium base and built-in double bearings reduce lateral wobble for steady, repeatable drilling
- • Best for: Carpenters, kitchen fitters and DIY enthusiasts fitting 35mm concealed hinges to cabinet doors
- • Not ideal for: Boards thinner than 12mm or thicker than 25mm where the clamp and depth settings cannot secure material
All-metal aluminium alloy jig with a flat base and double bearings for stable drilling. Includes a 35mm hole saw, 2mm pilot bit and accessories for use with standard electric drills.
Accurate Hinge Cups – Thanks to built-in double bearings
Double bearings on the drilling locator reduce lateral movement during rotation, so the cutter remains centred while cutting the 35mm cup. A flat aluminium base keeps the jig flush against the door face for consistent geometry.
Precision drilling delivers repeatable hinge cup placement, reducing alignment fiddles during fitting. Accurate holes mean hinges sit flush and doors close more reliably.
Faster, Repeatable Set-up – With quick clamp and depth limit ring
A quick-clamp locking plate secures the jig to the door, while an adjustable limit ring sets the drill depth, typically at 12–13mm for hinge cups. Marking, clamping and drilling become a simple, repeatable sequence.
Faster installation across multiple doors, with consistent hole depth that avoids over-drilling. Time spent on alignment is reduced, making multi-door jobs more efficient.
Robust Workshop Use – With all-metal aluminium alloy construction
An aluminium alloy body offers greater rigidity than plastic alternatives, resisting wear and deformation under repeated drilling. Supplied wrenches and hex tool allow on-site adjustments and maintenance.
Durable construction withstands regular use, so the jig remains accurate over time. Included accessories mean immediate use and straightforward maintenance in the workshop.
