Product Description

The Irwin 63121 is a jobber length drill bit designed for heavy-duty applications. This drill bit is made from M-35 high-speed steel with five percent cobalt for improved durability. It is suitable for drilling hard steel, stainless steel, and titanium. This bit has a diameter of twenty-one sixty-fourths of an inch and an overall length of four and five-eighths inches, making it versatile for various tasks. The spiral flute design helps with chip ejection, while the shorter cutting lips are optimized for drilling materials with high tensile strength.
