Drill America DWDDL Series 3/16 x 18 High Speed Steel Extra Long Drill Bit

Drill America's DWDDL Series High-Speed Steel drill bits are designed for general-purpose drilling applications where extra length is required for reach. These drill bits are engineered to perform in a wide range of materials, including iron and steel.

The DWDDL Series drill bits are a dependable, general-purpose option suitable for a variety of materials, making them ideal for both production and maintenance tasks. The bright finish on these tools provides superior chip evacuation, which helps to reduce clogging during use.

High-speed steel is a popular choice for general-purpose applications, as it offers a combination of hardness and toughness that contributes to wear resistance. Uncoated tools, such as those in the DWDDL Series, feature the base substrate without any additional treatments or coatings, making them suitable for a wide range of applications.

The round shanks on these drill bits allow for use with a variety of toolholding systems, providing flexibility and versatility to the user. When operated in a counterclockwise direction (right-hand cut), the spiral fluted design of the DWDDL Series tools helps to evacuate chips up and out of the cut, reducing the risk of clogging.

In addition to the base high-speed steel construction, the DWDDL Series drill bits also feature a black oxide treatment. This treatment adds lubricity to the tool and creates small pockets on the surface that help to hold coolant near the cutting edge, further enhancing performance and wear resistance.

Overall, the Drill America DWDDL Series High-Speed Steel drill bits are a reliable, general-purpose option for a wide range of drilling applications, particularly where extra reach is required. The combination of material properties, design features, and surface treatments make these drill bits a versatile choice for production, maintenance, and a variety of other drilling tasks.
