Welding Spot Grinder Set, 5% Cobalt Steel, 3pcs

The welding spot grinder set is a 3-piece drill bit kit designed for precise and efficient spot weld removal. Each drill is made from high-performance HSS-E cobalt steel (5% Co), offering superior resistance to heat and wear. The titanium-nitrided surface further enhances durability and reduces friction during drilling.

This set includes three commonly used diameters: Ø6.5mm, 8mm, and 10mm, making it versatile for various applications. The centering tip ensures accurate positioning, preventing the drill from walking on the surface—ideal for controlled and reliable drilling even on hard materials.

Thanks to the cobalt alloy content, these bits maintain sharpness even under high thermal stress, making them ideal for automotive, metalworking, and body repair applications.
