What Are Diamond Bit Rotary Drills Hydraulic Shovels
Drilling in mining
· Figure 4 Selection of rotary bit design Biggs and Cheatham (1969) [1] considered an idealized drill bit as two dimensional wheel and chipping action was illustrated as shown in Figure 5 Cheatham and Gnirk (1966) [2] determined that for producing chips some initial penetration D must be there. As shown in the figure Dc is the thickness of the chip.

Drilling mechanics and performance
The drill rate that can be achieved with a specific bit is determined by the aggressiveness of its design, the weight on bit (WOB) applied, the rotations per minute (RPM) and the rock strength. When the RPM or WOB are increased, the rate of penetration (ROP) should increase proportionately. If the increase is proportionate, the bit is efficient.
