The IRWIN® HSS Cobalt Drill Bit Set is ideal for tackling tough materials like stainless steel and other high-alloy metals. These high-quality drill bits feature a 135° split point for accurate centering and reduced drilling pressure, ensuring clean, precise holes every time. The industrial-quality ground flute design promotes fast chip removal and high-accuracy drilling, while the 5% cobalt content significantly extends the life of the bits by improving their red hardness (heat resistance).
The attractive golden tempered surface finish is a testament to their superior quality and durability. This comprehensive 15-piece set provides a wide range of sizes to cover most drilling needs.
