Dent Fix DF-1680T Titanium Nitride Spot Weld Drill Bit (8 x 45mm)

The DF-1680T is our most popular spot weld drill bit. 8 mm or 5/16 in is the most common size of spot welds that need to be removed. The titanium coating on this bit will help prevent the bit from dulling due to overheating. The twist is the same size as the shank which is also 8 mm and has a flat spot on it to be tightened into our DF-15DX Series spot weld drills. Our drill bits a specifically designed for the abuse of spot weld drilling. Flat ground for strength, centering nib to prevent walking. Our German made spot weld bits are available in 2 sizes 8 mm (DF-1680T) and 10 mm (DF-1610T). These cobalt high speed steel mix bits are 45 mm long and work with all brands of spot weld drills. Titanium (gold color) is a heat-resistant coating that extends drill life by about 50%.
