Sometimes bigger is better and when it comes to drilling or boring into thick material, bigger is definitely better. Introducing the Fulton high speed steel extra long brad point drill bit set. Each bit measures around 12 inches in total length to provide you with enough drilling length to tackle most any project you can throw at them..
Many times when working around the house or out on the job site, we come across a situation where we need to drill through thicker material like a 6 x 6 or 4 x 4 when building things like an privacy fence or even rough building applications. These Fulton extra long brad point drill bits are perfect for these situations!.
Made from high speed steel, these bits are ideal for many different project types and materials. Drill into MDF, 4 x 4’s, 6 x 6’s, PVC, Resin’s, Composites, Plywood and more. Since each bit has a sharp (brad point) tip, it is recommended that you do NOT use these bits to drill into metal objects..
Brad Point drill bits are specifically designed for better hole location accuracy. The sharp point on the tip allows you to precisely locate your mark with the bit and with a little pressure, the bit won’t slip or walk as you initiate the drilling process. This makes brad point drill bits excellent....
