Built for versatile metalworking tasks

Meet the OXTUL twist drill bit set, designed to handle metal, wood, and plastics with a reliable edge. Crafted from M2 high speed steel and finished with a protective bright coating, these bits are built for durability and consistent performance through repetitive drilling. ANSI standards and a Rockwell hardness range around HRC 62-63 back up their wear resistance, while the 12-piece pack keeps you ready for a variety of projects. Each bit measures a total length of 4 inches with an effective working length near 2.75 inches, making them suitable for handheld use in compact workshops or service vehicles.

Smart design for accurate, clean holes

The standout features combine to support smoother entry and cleaner results. A 135-degree split-point tip helps with self-centering, reducing wandering on initial contact. The spiral flute enhances chip evacuation, which can contribute to faster cutting and less clogging in common workpieces. A robust 3-flat shank improves chuck grip for steadier drilling, especially in less-than-perfect setups.
