1.30 mm: The
bit has a diameter of 1.30mm, which makes it suitable for applications
requiring small, accurate holes.
Material:
High-Speed Steel (HSS) or Cobalt:
Most small drill bits like the ST1.30mm 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 ST1.30mm 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 ST1.30mm 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 ST1.30mm are designed to resist wear
and maintain sharpness over time, although smaller bits can be more susceptible
to breakage if not handled carefully.
