## Summary description

Cylindrical cobalt metal drill bits GRAPHITE 57H010, Ø 1 mm, set of 5 pieces. Designed for drilling ferrous and non-ferrous metals, these cobalt alloy bits offer improved heat resistance and wear performance for manual and machine drilling. Suitable for precise small-diameter holes in sheet metal, thin plates and metal components in repair and fabrication tasks.

## Long description

Cylindrical cobalt metal drill bits GRAPHITE 57H010, Ø 1 mm, set of 5 pieces are designed for precise small-diameter drilling in ferrous and non-ferrous metals. The cobalt alloy composition increases heat resistance and wear performance compared with standard high-speed steel bits, enabling stable drilling in thin plates, sheet metal and metal components. The cylindrical shank is suitable for use in hand drills, drill presses and other machine tools that accept smooth shanks of this diameter.
Advantages
The cobalt alloy cutting edges retain hardness at elevated temperatures, which reduces edge wear and extends service life when drilling metal. The 1 mm diameter provides accuracy for small holes and fine work, while the set of five bits ensures quick replacement when one becomes dull. The cylindrical shank allows secure clamping in standard chucks and supports both manual and machine operation. These bits are manufactured to consistent dimensions to maintain repeatability in series drilling tasks.
Suitable for
 Drilling small holes in sheet metal and thin plates
 Repair and fabrication of metal components
 Precision tasks in metalworking and model making
 Use in hand drills, bench drills and small drill presses
Key specifications
 Material: cobalt alloy high-speed steel
 Diameter: 1 mm
 Shank type: cylindrical (smooth)
 Quantity: set of 5 pieces
 Intended application: ferrous and non-ferrous metals
How to use
Select an appropriate drill speed and feed for the metal being machined, typically higher speeds for thin non-ferrous metals and moderate speeds for ferrous metals to avoid overheating. Secure the workpiece and clamp the cylindrical shank firmly in the chuck. Use cutting fluid or lubricant when drilling stainless steel or thicker ferrous materials to prolong tool life and improve chip evacuation. Apply steady, moderate pressure and withdraw occasionally to clear chips from the hole.
Usage recommendations
For best results, start with a pilot or center punch to prevent wandering, use sharp bits and appropriate cutting fluid for stainless or hardened steels, and replace bits from the set as soon as wear affects hole quality to maintain dimensional accuracy.
