KEY FEATURE
High precision
Fully Grinding Processing makes the surface of drill bit smoother,the cutting speed is faster and accturate drilling.
Titanium coated
Titanium coating prevents rusting and increases wear resistance, providing continuous sharping for the drill bits.
High hardness
The drill bits made from premium quality high speed steel, good strength and durability.
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 bit and the workpiece are stable before use.
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.
