Drill America 3/8 HSS Split Point Drill Bit Pack of 6, D/ASP Series

The Drill America D/ASP series high speed drill bit is manufactured to the National Aerospace Standard 907. These drill bits are ideal for portable or machine drilling of low tensile strength alloy materials. The tools feature a black oxide surface treatment that is abrasion resistant, reduces chip welding, and improves chip flow.

High-speed steel tools are well-suited for most general-purpose applications, offering a combination of hardness and toughness for enhanced wear resistance. 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 helps to improve the tool's performance and longevity.

The round shanks of the drill bits allow for use with a wide variety of toolholding systems, making them versatile and easy to integrate into various drilling setups. When run in a counterclockwise direction (right-hand cut), the spiral fluted tools effectively evacuate chips up and out of the cut, reducing the risk of clogging and ensuring a smooth, efficient drilling process.

In summary, the Drill America D/ASP series high speed drill bits are designed to meet the rigorous requirements of the National Aerospace Standard 907. The combination of their robust construction, abrasion-resistant black oxide coating, and efficient chip evacuation capabilities make them well-suited for a wide range of portable or machine drilling applications involving low tensile strength alloy materials.
