1-3/4-inches (45mm) Long; Sizes 1/4-inch (6.5mm), 5/16-inch (8mm) and 3/8-inch (10mm); Each drill bit has permanently etched size markings
Non-slip special centering nib design with flat shaft for sure grip; pilot tip design increases accuracy and prevents slipping when held down for marking purposes.
Unlike pilot bits that drill through both surfaces, these bits are easy to control while cutting without penetrating the lower surface
Titanium coating offers a smooth drilling experience that prevents dulling from overheating for extended performance.
Use this spot weld drill bit to separate spot welds and resistance spot welding panels without distorting the sheet metal.Great for removing welding spot or drilling metal sheets
Description
