Narwhal 11-64 Cobalt Drill Bits – 13 Pack, M35 Cobalt, 135° Split Point, 3.15 in Length

Overview

Meet the Narwhal 11-64 cobalt drill bit set, a 13‑piece collection designed for metalworking with a focus on durability and precision. Crafted from M35 cobalt, these bits resist heat and wear, helping you maintain consistent diameter as you work through tougher materials. Each bit is fully ground and features a 135‑degree split point, which eases starting holes and reduces wandering on harder surfaces. With a total length of 3.15 inches and a flute length of 1-7/8 inches, you gain a balanced load of rigidity and reach for a variety of tasks.

The kit is built to perform where traditional high-speed steel may struggle. The cobalt alloy is chosen to stand up to demanding metals, while the split point helps you begin holes cleanly in metal, cast iron, and other challenging substrates. The design details—precise diameter control and robust geometry—support reliable drilling even as you push through tougher workpieces.
