Drill America 3/16 High Speed Steel Split Point Drill Bits (Pack of 12), D/ASP Series

Drill America's D/ASP series high-speed drill bits are manufactured to the National Aerospace Standard 907, making them ideal for portable or machine drilling of low tensile strength alloy materials. The black oxide surface treatment on these tools is abrasion-resistant, reducing chip welding and improving chip flow. This high-speed steel tool offers a combination of hardness and toughness, providing excellent wear resistance for most general-purpose applications.

The black oxide treatment adds lubricity to the tool and creates small pockets on the surface that help hold coolant near the cutting edge. This feature enhances the tool's performance and efficiency. The round shanks of these drill bits allow them to be used with a wide variety of toolholding systems, making them versatile and adaptable to different drilling setups.

When run in a counterclockwise direction (right-hand cut), the spiral-fluted design of these drill bits evacuates chips up and out of the cut, reducing the risk of clogging. This efficient chip evacuation helps maintain the tool's performance and extends its lifespan.

In summary, the Drill America D/ASP series high-speed drill bits are engineered to meet the high standards of the National Aerospace Standard 907, ensuring their suitability for a wide range of drilling applications involving low tensile strength alloy materials. The combination of abrasion-resistant black oxide treatment, wear-resistant high-speed steel construction, and innovative features like lubricity-enhancing pockets and efficient chip evacuation make these drill bits a reliable and efficient choice for various drilling tasks.
