Please note that Forstner drill bits should be larger than 0.8" in diameter to prevent the protruding part of the set screw from scratching the hole wall when drilling. ★ Attention: 1.Due to the different monitor and light effect, the actual color of the item might be slightly different from the color showed on the pictures. 2.Please allow little measuring deviation due to manual measurement.
