Precision 1 inch HSS Black Oxide Twist Drill Bit with Straight Shank

The High-Speed Steel (HSS 6542) Reduced Shank Drill Bit features a cutting diameter of 25mm (0.98") and a shank diameter of 1/2". The cutting edge length is 77mm (3.03"), and the overall length is 152mm (6.0"). This drill bit is designed for most general-purpose applications, offering a combination of hardness and toughness for excellent wear resistance.

The reduced shank design expands the size range capacity of a portable drill chuck, allowing for common flute and overall length with minimal adjustment during tool changes. The black oxide finish adds lubricity to the tool, and small pockets on the surface help hold coolant near the cutting edge, further enhancing the tool's performance.

This drill bit is well-suited for drilling in low and medium tensile strength materials, such as aluminum, iron, copper, brass, and other metals. The spiral flute design allows the tool to run in a counterclockwise direction (right-hand cut), effectively evacuating chips up and out of the cut to reduce clogging.

To ensure clean and precise holes, it is recommended to use water for lubrication and cooling when drilling metals. Increased use of water lubrication will extend the drill bit's lifespan, as it helps to dissipate heat and reduce wear on the cutting edges.

In summary, the High-Speed Steel (HSS 6542) Reduced Shank Drill Bit is a versatile and durable tool that can handle a wide range of general-purpose drilling applications. Its design features, such as the reduced shank, black oxide finish, and spiral flute, contribute to its performance and efficiency when working with various metal materials.
