Need a reliable drill bit for tough materials? This IRWIN 1/4-inch left-hand cobalt drill bit is designed for heavy-duty metal drilling. The 135° split point design helps reduce walking and provides faster starts, while the cobalt steel construction offers superior heat resistance and durability compared to standard bits. It’s a left-hand spiral bit, which can be handy for removing broken bolts or screws. Sold in a bulk 135-foot length (likely a typo—typically sold as individual bits or sets; verify packaging), it’s a professional-grade option for mechanics, fabricators, or serious DIYers. Ideal for drilling into stainless steel, cast iron, and other hard metals. Whether you’re working on automotive projects, metal fabrication, or home repairs, this bit delivers precision and longevity. Add it to your toolbox for when you need extra drilling power.
