Drill Bit Set, DWDLH Series

The Drill America DWDLH series polished jobber length drill bit is a general-purpose drill construction. The left-hand helix feature makes it suitable for screw machine applications where spindles rotate counter-clockwise. Additionally, this left-hand drill can be used to drill out broken bolts.

High-speed steel tools are recommended for most general-purpose applications, as they offer a combination of hardness and toughness, providing excellent wear resistance. Uncoated tools feature the base substrate without any additional treatments or coatings, making them suitable for a wide range of applications.

The round shanks of these drill bits allow for use with a variety of toolholding systems. An important feature of these drill bits is their reverse flute design, which causes them to run in the opposite (clockwise) direction from regular drill bits when making holes.

The left-hand helix design of the Drill America DWDLH series is particularly beneficial for screw machine applications where the spindles rotate counter-clockwise. This feature helps to ensure efficient and effective drilling performance in these specific applications.

The uncoated nature of the tools means they do not have any additional treatments or coatings, which allows them to be used in a wide range of applications. The base substrate material, high-speed steel, provides the necessary hardness and toughness to handle general-purpose drilling tasks while offering good wear resistance.

The round shanks of the drill bits allow for compatibility with a wide variety of toolholding systems, providing users with greater flexibility in their drilling operations. The reverse-flute design, which causes the drill bits to run in the opposite (clockwise) direction from regular drill bits, is a unique and advantageous feature for certain drilling applications.

Overall, the Drill America DWDLH series polished jobber length drill bits are a versatile and capable solution for general-purpose drilling tasks, offering a combination of features and benefits that make them suitable for a wide range of applications.
