Drill bits come in a wide range of shapes and sizes, and are available in a variety of materials and coatings. Most tooling and machining
operations have a drill bit that’s designed specifically for the task. Here’s a quick overview of several types of drill bits, materials and
design types.
Made From HIGH-SPEED Steel and 5% Cobalt,improve much higher heat resistance because of cobalt steel's high
red hardness, provide strong durable performance compared to typical hss drill bits
Accurate and Neat: 135°Quick-Cut points are self-centering and penetrate quickly with less pressure.
