7/8 Reduced Shank High Speed Steel Drill Bit with 1/2 Shank - DWDRSD Series

The high-speed steel (HS Steel) tools are ideal for most general-purpose applications, offering a combination of hardness and toughness that provides excellent wear resistance. These tools are ground to a precise 118-degree point, expanding the size range capacity of a portable drill chuck.

The common flute and overall length design minimizes the need for adjustment during tool changes, enhancing efficiency. Precision grinding ensures a high degree of concentricity between the shank and body diameter, contributing to the tools' accuracy and performance.

The black oxide finish on these tools adds lubricity and creates small pockets on the surface, which act to hold coolant near the cutting edge. This feature helps to reduce clogging and improves the tools' overall effectiveness when drilling in low and medium tensile strength materials.

When run in a counterclockwise direction (right-hand cut), the spiral fluted tools are designed to evacuate chips up and out of the cut, further reducing the risk of clogging. This innovative design enhances the tools' efficiency and versatility, making them a reliable choice for a wide range of drilling applications.

The round shanks on these HS Steel tools allow for use with a variety of toolholding systems, providing users with increased flexibility and convenience. This feature, combined with the tools' precision, durability, and specialized surface treatment, makes them an excellent choice for both professional and DIY applications.

Overall, these high-speed steel tools are a well-engineered solution for general-purpose drilling tasks, offering a combination of performance, reliability, and versatility that sets them apart from other options on the market.
