What they are used for
Printed circuit boards are usually made of fibreglass (FR4), which due to being highly abrasive, specialist drill bits are required, especially given the many hundreds or thousands of holes on most circuit boards.
We stock PCB Carbide Micro Drills from 0.2mm through to 3mm. Our drill descriptions describe the flute diameter and the flute length. Other dimensions are standard accross the range.

0.4mm x 7mm
equates to a drill of D=0.4mm and L=7.0mm
2.4 x 10.5
equates to a drill of D=2.4mm and L=10.5mm
Please note: we stock ONLY new drills , we DO NOT offer reground bits. Though we primarily stock drills for PCB manufacture, Drills are suitable for drilling Aluminium, Brass, Bronze, Cast Iron, Copper, GRP, PCB, Stainless and Hardened Steels etc. Ideal for model engineering, electronics and jewellery making, etc.

Risk from these exposures varies depending on how often this type of work is performed and the amount of individual exposure. To reduce the amount of exposure to harmful chemicals and materials:
- Work in a well ventilated area
- Avoid breathing in dust or mist
- Use approved methods of dust and mist control
- Avoid prolonged skin contact with dust or mist
- Consult the power tool manual for proper use of the power tool and safety equipment requirements.
- Use approved safety and protective equipment: Gloves, shields, dust masks, protective clothing, tool guards, etc.
