this instance displacements 44 have been inserted into small cavities 22 u2032 as shown in fig4 through 7 slots or grooves 48 48 u2032 which subsequently form bearing elements 42 fig1 may be formed in mold 46 e g by milling the same into the surface of the cavity 45 of mold 46 grooves 48 48 u2032 and small cavities 22 u2032 may be formed by way of non limiting example by hand milling or by a multi axis e g five or seven axis milling machine under control of a computer for example only among other factors the size shape area and depth of each groove 48 48 u2032 may be selected to achieve a desired doc i e aggressiveness and bearing element area for a given application or formation as aforementioned each groove 48 48 u2032 has a substantially uniform depth across substantially an entire area thereof regardless of the contour of the surface within which groove 48 48 u2032 is formed each groove 48 48 u2032 may for example have a width that is slightly greater than the widths of small cavities 22 u2032 in the mold 46 and further extend somewhat between adjacent small cavities 22 u2032 such configurations may provide greater bearing surface areas and may support a higher applied wob than would otherwise be possible if the drill bit 10 lacked such features alternatively each groove 48 48 u2032 may have a width somewhat less than the widths of small cavities 22 u2032 in this.
