Tool bit design innovation has been progressing on many fronts through the years. Many companies have come up with innovative Tool bits with major development ranging from reducing cutter wear to design enhancements. Also, innovations have been seen in providing longevity to the bit and improve bits penetration rates.
Given below are tool bits manufactured by various companies which has contributed to the improved properties of tool bit in one form or another.
Smith Bits, a Schlumberger company:
ONYX 360 rolling PDC helps in reducing time consuming trips of changing bits by providing increased bit durability. This is achieved by making the bit free to revolve 360° during drilling. Due to 360 degree rotation, fresh cutting face of the bit is always in touch with the material, thus increasing the bit’s overall life by an average of 50%. Also, as the whole surface of the tool bit is used all the time, wear is reduced on the bit which results in fewer replacement of tool bits.
MegaForce bit by Halliburton
The tough new MegaForce bit has an improved blade design to overcome transition forces. The innovation applied in this bit has helped cutters sustain greater transition force. In a scenario where the bit grind slowly into a hard rock, then whirls through the soft part of the rock in the middle, picking up momentum and torque. Suddenly, it hits another hard part of the rock. This transition can break or put lots of stress on the tool. This new MegaForce bit has been designed to overcome such transition forces. These bits have strategically placed "micro" nozzles which helps in directing the flow of cut. In further enhancement to this bit, the bit has been designed with a shorter shank length and 14% reduction of bit-to-bend distance, to improve directional control.

Imax and Imax+ bits by Varel International
Diamond impregnated bits help in drilling through the toughest of material. Imax drilling bit takes this technology to the new level by providing innovation with the strict diamond selection procedure featuring diamonds of similar size and quality, improved diamond-matrix bonding, and a new process that ensures uniform diamond distribution. The innovation in design created by Varel International allows customization to address specific formations or specific basin characteristics. Parameters like matrix hardness, diamond size, and concentration can all be varied to match the application with this new design.

NOV’s SpeedDrill bit
NOV has invented a cutter index where index can be selected depending on a particular set of condition. The cutter index divides the resistance into 3 failure mechanism, i.e. thermal degradation, abrasion, and impact. This helps in cutters to use the suitable index for a specific grade of material.

This has helped in increasing the efficiency and improving stability of the tool. This has also contributed to reduced vibration related tool failures, improved borehole condition, and cost savings.
