PCB DRILL BIT

PCB（Printed Circuit Board）, also called printed circuit board. It is glued
together by several layers(4 layers, 6 layers or 8 layers) of resin materials,
and copper foil is used for wiring inside. PCB drill bit is mainly used for PCB
drilling, which accounts for 30 % to 40% of the cost of printed circuit board.
The mass production often needs special equipment and drill bit.

CNC drilling machine uses cemented carbide fixed shank PCB drill bit. The
common drill shank diameters are 3.00mm and 3.175mm, can be replaced
automatically. Cemented carbide PCB drill has high positioning accuracy and
does not need to use drill sleeve. Large helix angle, high chip removal speed,
suitable for high speed drilling. In the whole length of the chip removal
groove, the diameter of the bit is an inverted cone, the friction between the
bit and the hole wall is small, and the drilling performance is very good.
