Drill America 1/8 High Speed Steel Black Oxide Drill Bits (Pack of 12), D/an Series

The Drill America D/AN series high-speed drill bit is a dependable, general-purpose drill designed to perform in a wide range of materials in the iron and steel families. Surface-treated with abrasion-resistant black oxide, these high-speed steel tools offer a combination of hardness and toughness for wear resistance, making them suitable for most general-purpose applications.

The black oxide treatment adds lubricity and creates small pockets on the surface of the tool, which act to hold coolant near the cutting edge. This feature helps to reduce clogging and improve the overall performance of the drill bit.

The round shanks of the drill bits allow for use with a variety of toolholding systems, providing versatility and flexibility in different drilling setups. When run in a counterclockwise direction (right-hand cut), the spiral fluted tools effectively evacuate chips up and out of the cut, further reducing the risk of clogging.

These Drill America D/AN series high-speed drill bits are ideal for a range of applications, including production, maintenance, and portable drilling jobs. Their durability and versatility make them a dependable choice for a broad spectrum of drilling tasks in the iron and steel industries.
