KEY FEATURES
High Precision
Manufactured in strict accordance with ANSI B94-11M, and fine grinding flutes to ensure hole accuracy.
High Hardness
The material contains 5% cobalt alloy which increases the hardness and wear resistance of the drill,perfect suitable for drilling in hard metals.
Easy Self-centering
135° split point design improves cutting speed while easy self-centering, prevent walking and skating across the workpiece surface.
INSTRUCTIONS FOR USE
Please make sure that the drill and the workpiece are stable before use. It is strongly recommended to use a drill press when drilling thick metal.
To avoid breaking the drill bit when drilling, please keep the drill bit perpendicular to the workpiece.
Please adjust the RPM to the lowest when you start drilling metal.
The friction between the drill bit and the workpiece will generate a amount of heat when drilling, it is necessary to use coolant liquid during the drilling process.
