Design characteristics and manufacturing processes for the two bit types are, in respect to body construction, different, because of the nature of the materials from which they are made. To improve the hydraulics, the fluid flow pattern across the drill bit should be optimized for low pressure droplow, recirculation flow and high velocity. 0000014587 00000 n When the RPM or WOB are increased, the rate of penetration (ROP) should increase proportionate-ly. Compare bit performance to identify best bit design. 23 Printable Tap Drill Charts [PDF] A drill and tap chart is what specifies the right size of drill bit that one can use to create the correct sized opening that would complement tap dimensions. The drill rate that can be achieved with a specific bit is de-termined by the aggressiveness of its design, the weight on bit (WOB) applied, the rotations per minute (RPM) and the rock strength. DRILL BIT MODELING As mentioned above, when we model the interaction between the bit and rock, the indentation model of a single tooth is the entry for ROP modeling. 0000097671 00000 n The shank is the part of the drill bit grasped by the chuck of a drill.
