If you drill a lot of stainless steel, steel, or cast iron, having multiple fresh bits in the same size can save time and frustration. The SALI Cobalt Drill Bit Set includes 10 jobber-length bits in 3/16 inch (4.76 mm), made from M35 cobalt high speed steel (5% cobalt) to boost wear resistance and durability versus typical HSS sets.

Each bit features a fully ground spiral flute to help clear chips efficiently, reducing friction and heat for smoother drilling. A 135° split point with a straight shank is designed to help prevent walking and improve accuracy—often letting you start holes without a center punch (application dependent).

The included molded index storage case keeps the set organized, with size markings on the lid for quick identification. It’s also part of a connectable accessory storage system to help optimize storage space in your toolbox.

Tip: For best results in harder metals, pay attention to speed, pressure, and heat control during drilling.
