Drill America DWDA/CX121 2.5 x 12 High Speed Steel Aircraft Drill Bit

The Drill America DWDA/C Series High-Speed Steel drill bit is designed in accordance with National Aerospace Standard 907. Featuring a 135-degree split point, this drill bit is self-centering, which effectively reduces thrust during operation. It is particularly well-suited for drilling into mild steel where additional length is necessary for better reach.

The drill bits are treated with a durable black oxide surface that provides excellent abrasion resistance. This treatment not only enhances wear resistance but also helps minimize chip welding and improves chip flow, making the drilling process more efficient. High-speed steel tools are versatile and suitable for a wide range of general-purpose applications. They strike an impressive balance between hardness and toughness, ensuring effective performance even under demanding conditions.

The black oxide treatment offers an added advantage by introducing lubricity to the surface of the tool. This creates small pockets on the drill bit's surface that effectively retain coolant near the cutting edge, promoting cooling during operation and extending the lifespan of the tool.

Additionally, the round shanks of these drill bits facilitate compatibility with a variety of tool-holding systems, enhancing flexibility and ease of use across different machining setups. When operated in a counterclockwise direction (right-hand cut), the spiral fluted design efficiently evacuates chips from the cutting area. This action helps to prevent clogging and maintains a clear path for the drill bit, improving performance.

Overall, the Drill America DWDA/C Series drill bit stands out not only for its adherence to rigorous industry standards but also for its innovative features that enhance drilling efficiency, wear resistance, and versatility. Whether you are working with mild steels or engaging in various other machining tasks, this high-speed steel drill bit promises reliable performance, making it an excellent addition to your toolset.
