Drill America DWDA/CX63/16 3/16 x 6 High Speed Steel Aircraft Extension Drill Bit (Pack of 12)

The DWDA/C Series High-Speed Steel drill bit, manufactured by Drill America, conforms to the National Aerospace Standard 907. Featuring a 135-degree split point, this drill bit is self-centering and reduces thrust, making it ideal for drilling in mild steels where an extended reach is required. The drill bit's surface has been treated with a black oxide coating, which provides abrasion resistance, reduces chip welding, and improves chip flow.

High-speed steel tools are versatile and suitable for a wide range of general-purpose applications, offering a balance of hardness and toughness for improved wear resistance. The black oxide treatment not only adds lubricity but also creates small pockets on the tool's surface that help to retain coolant near the cutting edge, enhancing the tool's performance.

The round shanks of these drill bits allow for use with a variety of toolholding systems, providing flexibility in the workshop. When operated in a counterclockwise (right-hand cut) direction, the spiral flutes of the tools effectively evacuate chips up and out of the cutting area, reducing the risk of clogging.

Importantly, these drill bits are manufactured in accordance with the National Aerospace Standard 907, ensuring a high level of quality and consistency. This adherence to industry standards makes the DWDA/C Series drill bits a reliable choice for a wide range of drilling applications, particularly in the aerospace and engineering sectors.

In summary, the Drill America DWDA/C Series High-Speed Steel drill bits offer a combination of features and performance characteristics that make them well-suited for a variety of general-purpose drilling tasks. From their self-centering, thrust-reducing split points to their abrasion-resistant black oxide coatings and efficient chip evacuation, these drill bits are designed to provide reliable and efficient drilling results in a range of materials.
