【High-Quality Material】Concealed Hinge Jig We use high-quality aluminum alloy material, precise manufacturing, accurate positioning, sharp drill bit, easy to use, wear-resistant and durable, long service life. This very practical woodworking punch is an excellent tool set for furniture factories and woodworkers to install concealed hinges on doors or cabinets. 【Double Clamp Design】 We have upgraded the hinge jig's three-layer drill bushing to reduce the drill's swing distance and improve the accuracy of hole opening. Double clamps on the front and back, firmly fix the layout again without damaging the finish. Applicable door thickness: 15-25 mm, opening depth 10-15 mm. 【Margin Adjustment Function】 The total height of the upper, middle, and lower load-bearing drill bushing on the hinge jig is 2 cm. The higher the height, the lower the vibration of the drill and the more accurate the drilling. We have added the margin adjustment block and 2 adjustment screws, the distance between the 35 mm hole and the edge can be adjusted between 3 and 7 mm, while the distance between the 35 mm hole and the edge in the old version was fixed at 5 mm. 【Installation Method】1. Install the margin adjustment block; 2. Install the 35 mm hole saw, adjust the drilling depth to 12-13 mm and lock the limit ring. 3. Adjust the fixing size of the black pressure block on the quick release; 4. Move the drill guide to the marking and drilling position on the plate and lock the quick release; 5. Punch the holes with the drill to a depth of 12-13 mm, drill 2 holes for 2 mm screws. 【Cabinet Hinge Punch Set】1*hinge drill, 1*35 mm hole saw, 1*upper link bearing, 1*depth locating ring, 2*wrenches, 1*2 mm drill bit, 1*hex wrench.
