Made in USA W.L. Fuller Model No. 25149005C Set of five HSS brad point drill bits with quick change adapter ends SAE fractional sizes: 1/8\”, 3/16\”, 1/4\”, 5/16\”, 3/8\” Quick change Designed for wood material Two hex-socket set screws in each adapter – 3/32\” hex key included Product Description Specs A high quality 5-piece brad point drill bit set with quick change by WL Fuller. These brad points are made of High Speed Steel to hold their sharp cutting edges longer. Brad points should provide the cleanest, straightest, & most accurately sized hole in wood of any reasonably priced drill bit tool on the market today. The brad in the center of the point allows accurate positioning when starting a hole even if the hole is not 90 from the surface. The outlining spurs sheer the wood grain & leave a clean edge around the opening of the hole eliminating the need for sanding. The spurs continue to sheer the wood while drilling & produce an accurately sized hole. In most woods, the spurs also help to produce a cleaner edge when drilling through the backside of the wood. There is a non-slip flat on the shank of the drill where the set screws of the 1/4\” hex power quick change adapter should be set. SAE fractional sizes: 1/8\”, 3/16\”, 1/4\”, 5/16\”, 3/8\”.
