0.9mm Diameter large shank micro drill bit is ideal for the delicate drilling of hard materials for model engineering, jewellery making and model making.
It is especially suited for drilling printed circuit boards. Made of fibreglass, printed circuit boards require a tough micro drill and these tungsten carbide drills will outperform similar HSS drill bits.
Extra care is needed when handling and using these micro drills as they are very delicate, especially the smaller sizes.
The large 3.175mm 1/8th inch shank reduces the risk of drill breakage.
Overall length approximately 38mm.
These drill bits are fitted with drill collars for ease of use and identification and colours may differ from image.
These can be used to replace those drills broken in our large shank drill sets.
