These long drill bits have an excessive length to slenderness ratio; care must be taken in use to reduce the incidence of bending or breaking.. If the bits are not used progressively or are used with excessive weight being added to the drill then you will bend or break them before you wear them out. It is important to start with the shortest bit, working progressively through each length and to let the drilling machine do the work. It is also recommended that initial holes are made using smaller, standard size drill bit.
