## Summary description

Cobalt cylindrical drill bit set by GRAPHITE, model 57H062-5, includes five 12 mm diameter bits designed for drilling in hard materials. Made with cobalt alloy for increased heat resistance and wear durability, suitable for metalworking, stainless steel, and other demanding applications where higher hardness and temperature stability are required.

## Long description

GRAPHITE cobalt cylindrical drill bit set, model 57H062-5, contains five 12 mm diameter drill bits engineered for drilling in hard materials. Each bit is manufactured from a cobalt alloy that increases heat resistance and wear durability compared with standard high-speed steel, making the set appropriate for demanding metalworking tasks, including stainless steel and other high-strength alloys.
Advantages
The cobalt composition provides improved hardness at elevated temperatures and greater cutting life when working with tough metals. Cylindrical shanks ensure secure mounting in standard chucks and reduce runout for more accurate holes. The set of five identical-diameter bits offers quick replacement on job sites or in production environments, reducing downtime when bits wear and need swapping.
Suitable for
 Drilling stainless steel and other hard metals
 Workshop and industrial metalworking tasks
 Maintenance and repair where high-temperature resistance is needed
 Machining thicker or alloyed metal parts
Key specifications
 Diameter: 12 mm
 Quantity: 5 pieces
 Material: cobalt alloy (high-temperature resistant)
 Shank type: cylindrical
 Intended materials: hard metals, including stainless steel
How to use
Select a drill or drilling machine compatible with 12 mm cylindrical shanks and secure the bit in the chuck to the recommended clamping length. Use appropriate cutting speed and feed for cobalt alloy bits and the workpiece material; when drilling stainless steel or other hard alloys, use lower cutting speeds and steady feed to avoid excessive heat. Apply cutting lubricant or coolant when recommended for the work material to extend tool life and improve chip evacuation. After drilling, inspect the hole and the bit for wear and replace bits from the set when cutting performance declines.
Usage recommendations
For best results when drilling stainless steel or other high-strength alloys, use a suitable cutting fluid, moderate spindle speeds, and firm clamping of the workpiece. Regrind or replace worn bits rather than applying excessive force, which can cause tool failure or poor hole quality.
