Replacing a triangle bit is quick and easy, and replaceable bits give you the ability to use a single screwdriver base while changing bits as per your requirements. When you are shopping on eBay, you can find a number of sellers who deal in triangle bits. It is important that you pay attention to aspects like the width of the bit, diameter of the shank, and total length, as these can vary from one bit to the next. For example, triangle bits sell in different widths, like 2 mm, 2.3 mm, and 2.8 mm. Shank diameter can be 5 mm or 6 mm, and the total length of a triangle bit can be 50 mm or 60 mm. Triangle bits also sell as part of bit sets, which may or may not include screwdrivers. Other bits you can expect to find in such kits include torx bits, slotted bits, crosshead bits, and tri-wing bits. You never know when you may damage a triangle bit, so keep a few as spares.
