Cleveland Jobber Length Cobalt Drill Bit - Size 8, 135° Point Angle, TiAlN Coated (C11408) - Perfect for Metalworking, Woodworking & DIY Projects

The TiAlN coating on these drill bits withstands high temperatures and protects the bits from wear during high-speed, dry machining applications with difficult-to-machine ferrous metals. Parabolic-flute drill bits have wide, deep flutes that improve chip flow and heat dissipation, which means feed rates do not need to be reduced as the drills move deeper into the workpiece.,Cobalt jobber-length drill bits tolerate higher drilling speeds and are harder and more wear-resistant than high-speed steel drill bits. They provide some shock absorption and can be used in handheld power tools. Jobber-length drill bits are the most commonly used drill-bit length. They provide a good balance of strength and accuracy when drilling into a variety of materials.
