DRILL BIT ST2.1mm

DRILL BIT ST2.1mm

Main Features:

Diameter:

• 2.1 mm: The bit has a diameter of 2.1 mm, which makes it suitable for applications requiring small, accurate holes.

Material:

• High-Speed Steel (HSS) or Cobalt: Most small drill bits like the ST2.1mm are made from high-speed steel (HSS) or sometimes cobalt for added hardness and heat resistance.

Flute Design:

• Spiral Flutes: Typically, drill bits have spiral flutes that help remove debris from the hole while drilling.

Point Type:

• Twist Drill: The ST2.1mm drill bit is likely a twist drill, which has a pointed tip designed for starting the hole and spiralled flutes for cutting.

Shank:

• Straight Shank: Most small drill bits have a straight shank that fits into a standard chuck.

Precision:

• High Accuracy: Due to its small diameter, the ST2.1mm drill bit is engineered for high precision.

Applications:

• Electronics and Circuit Boards: Commonly used for drilling tiny holes in PCBs (Printed Circuit Boards) or electronic components.
• Jewellery and Crafting: Useful for making small holes in jewellery pieces or intricate crafts.
• Small Mechanical Parts: Suitable for precision work in small mechanical assemblies or repairs.

Durability:

• Wear Resistance: High-quality drill bits like the ST2.1mm are designed to resist wear and maintain sharpness over time, although smaller bits can be more susceptible to breakage if not handled carefully.
