The teeth of a milled tooth bit and the inserts of an insert bit for the cutting structure of the bit.
The selection of a milled tooth or insert bit is largely based on the hardness of the formation to be drilled.
The design of the cutting structure will therefore be based on the hardness of the formation for which it will be used.
The main considerations in the design of the cutting structure is the height and spacing of teeth or inserts.
