Formdrill manufactures thermal drill bits, Formdrills, which help you Form your Own Inserts in thin materials. These tools form the hole and push through the displaced material, that is normally cut, to form a bushing that triples the original material thickness. These bushings can then be tapped to avoid the use of welded nuts or inserts. Resulting joints can be as strong or stronger than the equivalent welded nut. Formdrills can be used in most drill presses, milling machines or CNC systems. They save labor, time and cost of materials.
