Drill America 3/8 HSS Heavy Duty Stub Drill Bit Pack of 6, DWDST Series

The Drill America DWDST series features high-speed steel screw machine length drill bits, manufactured to National Aerospace Standard 907. These drill bits boast a 135-degree split point design, which is self-centering and reduces thrust, making them ideal for portable or machine drilling applications.

The short, rugged construction of these drill bits allows them to perform well in a broad range of materials within the iron and steel families. Screw machine drills, such as those in the DWDST series, are widely used in the automotive and construction industries, particularly in setups where spindle clearance is limited.

High-speed steel is an excellent choice for general-purpose applications, as it offers a combination of hardness and toughness that provides superior wear resistance. The black oxide treatment applied to these drill bits further enhances their capabilities by adding lubricity and creating small pockets on the tool's surface that help to hold coolant near the cutting edge.

The round shanks of the DWDST series drill bits allow for use with a wide variety of toolholding systems, providing users with increased flexibility and versatility. When these spiral fluted tools are operated in a counterclockwise direction (right-hand cut), they effectively evacuate chips up and out of the cut, reducing the risk of clogging.

The DWDST series drill bits from Drill America are a reliable and versatile choice for a broad range of drilling applications. Their robust construction, specialized features, and compatibility with various toolholding systems make them a popular option in industries where high-performance, precision drilling is a necessity.

Whether you're working on automotive components, construction materials, or any other project within the iron and steel families, the Drill America DWDST series drill bits can help you achieve precise, efficient, and consistent results. With their self-centering design, reduced thrust, and effective chip evacuation, these drill bits are well-suited for both portable and machine-based drilling operations.

In summary, the Drill America DWDST series high-speed steel screw machine length drill bits offer a combination of durability, versatility, and performance-enhancing features that make them a go-to choice for a wide range of industrial applications. Their quality construction and adherence to industry standards ensure reliable and consistent results, making them a valuable addition to any workshop or production facility.
