About this item High Precision: The spot weld drill bit set includes 1/4-inch (6.5mm), 5/16-inch (8mm), and 3/8-inch (10mm) sizes, each with permanently etched size markings for easy identification. The pilot tip design ensures increased accuracy and prevents slipping during marking. Durable Construction: Made from high-speed cobalt steel (HSS Co), these spot weld drill bits are designed for long-lasting performance. The titanium coating provides heat resistance, ensuring smooth drilling without dulling from overheating, even in high-temperature environments. Non-Slip Design: Each spot weld drill bit features a non-slip centering nib design with a flat shaft for a secure grip. This design allows for easy control while cutting, preventing penetration of the lower surface and ensuring precise separation of spot welds. Versatile Application: Ideal for separating spot welds and resistance spot welding panels without distorting the sheet metal. These spot weld drill bits are perfect for removing welding spots or drilling through metal sheets, making them a versatile addition to any toolkit. Heavy Duty Performance: The special grade high-speed steel cobalt mix is engineered for a long service life, withstanding quick speed running rates. The flat ground surface on the bottom half of the bit provides additional strength and chuck hold on any welding drill.
