Until now, Pilot has been recognized mainly as the premier source of high quality diamond set tools for the exploration industry. Pilot's attention to detail, craftsmanship and understanding of the industry has now been united with state of the art powder metallurgy practice in the creation of a new range of impregnated bits.

Careful selection and blending of synthetic diamonds provides the foundation for the Pilot impregnated range. Metallic materials matched to the purpose, carefully developed processes and stringent quality controls round out the product.

By considering the drillability of the rock rather than concentrating only on hardness, we have judged the combined effects of abrasiveness, friability and hardness to develop a series of five products to meet the challenge of any formation.



Each member of the Pilot impregnated series has a broad range of application, predictable response and a tolerance of changing conditions which results in higher productivity, fewer bit changes and more core in the box at the end of the shift.

Impregnated Bit Crown Profiles

Pilot offers three standard impregnated crown profiles which will cover any commonly found ground condition. All share a face design that has been developed to provide reinforcement where it is most needed, while minimizing the risk of unwanted deviation.

Standard crown

The waterway design and number of segments on the standard profile have been selected to provide a robust yet productive tool which can take on variable formations without seriously affecting performance. It is the default choice when facing the unexpected.




Turbocrown

The Pilot Turbo crown has been developed by paying close attention to the hydraulic effects that take place around the water courses, especially at the higher peripheral speeds that can be expected when the user seeks maximum penetration rate. The result is a tool that stays effectively flushed and cooled, even when driven beyond the normally accepted parameters for wireline bits. Productivity can only be truly maximized when the simple effect of pushing up the penetration rate is balanced by efficient flushing to prevent uneven wear and premature failure.




Face Discharge crown

For use in unconsolidated formations, where there is a chance that fluid can be lost in the formation without performing vital flushing, it is usual to select a face discharge bit. Pilot has taken a different approach from conventional face discharge design, optimising the chance of adequately clearing the cuttings while minimizing the chance of washing away the more fragile core.
