Westward 6PRY2 Jobber Length Drill Bit Introducing Breakthrough Durability with a special TiN coating that shields these bits from wear and high temperatures, making them perfect for drilling steel, stainless steel, and aluminum. This means lasts longer and fewer replacements are needed. The wider, deeper design efficiently removes chips as you drill, keeping the bit cool and preventing binding. This allows you to maintain speed and achieve clean, precise holes even in deep cuts. The straight shank ensures compatibility with most drill chucks and tool holders.
