Drill America DWDRSD Series 19/32 Reduced Shank High Speed Steel Drill Bit

These high-speed steel (HS) drills are designed to expand the size range capacity of a portable drill chuck. They are ground to a 118-degree point and feature a common flute and overall length, minimizing the need for adjustment during tool changes. The precision grinding ensures a high degree of concentricity between the shank and body diameter, making them ideal for drilling in low to medium tensile strength materials.

The black oxide finish not only adds lubricity but also creates small pockets on the tool's surface that help hold coolant near the cutting edge. This feature enhances the drills' performance and wear resistance, making them suitable for a wide range of general-purpose applications.

The round shanks on these HS steel tools allow for use with a variety of tool holding systems, increasing their versatility. When the drills are run in a counterclockwise direction (right-hand cut), the spiral flutes efficiently evacuate chips up and out of the cut, reducing the risk of clogging.

The combination of hardness and toughness in the HS steel construction provides these drills with excellent wear resistance, ensuring consistent and reliable performance. The precision grinding further contributes to their accuracy and concentricity, making them well-suited for drilling in low and medium tensile strength materials.

The black oxide finish serves multiple purposes. It not only adds a protective layer to the tools but also enhances their lubricity, which is particularly beneficial when working with tough materials. Additionally, the small pockets created by the finish help to hold coolant near the cutting edge, improving the overall efficiency and effectiveness of the drilling process.

The round shanks on these HS steel drills offer versatility, as they can be used with a wide range of tool holding systems. This flexibility allows users to adapt the drills to their specific needs and equipment, ensuring optimal performance in various applications.

When the drills are operated in a counterclockwise direction (right-hand cut), the spiral flutes efficiently remove chips from the cut, minimizing the risk of clogging. This feature helps to maintain a clean and efficient cutting process, contributing to the overall quality and consistency of the finished work.

Overall, these HS steel drills are a reliable and versatile choice for a wide range of general-purpose drilling applications. Their precision, wear resistance, and innovative design features make them an excellent option for professionals and hobbyists alike, who require high-quality tools that can handle low to medium tensile strength materials with ease.
