Description: High Speed Steel Black Oxide Reduced Shank Drill Bit with 1/2 inch Shank Twist Drill Bit.
Drills are precision ground to maintain a high degree of concentricity between shank and body diameter.
These bits are ideal for drilling in low and medium tensile strength materials.
76mm flute length and 152mm overall length.
Black oxide treatment adds lubricity and creates small pockets on the surface of the tool that act to hold coolant near the cutting edge.
