Claims:

I claim;



1. The use and application of Technogenia® and any of its associated products will significantly extend the wear life of any tooling used within the fields of industry that I have indicated in my abstract.

2. This product when compared to all known methods and products will far surpass and out last any known hardsurfacing/hardfacing product now available.

3. I claim the use and application when used of applied to any following tools associated within the horzontal directional drilling, oil field industry (HDD), vertical drilling, oil field industry, utility construction, mining industry, road/highway construction, primary tools, drilll bits, reamers, all housings drill rods, housing savers, collars, all collars, lead roads, toll adapters, shanks, sub savers, all roller cones, hole openers, hole expanders, drag bits, augers, plow blades, trencher teeth, scraper buckets, scraper blades, buckets, mud motors.

Description:
[0001] I discovered a new use for technogenia® and this use is its application to tooling used in the following industries.

[0002] A. HDD (Horzinital Directional Drilling)

[0003] B. mining industries

[0004] C. quarry industries

[0005] D. road construction and maintenance

[0006] E. utility construction and maintenance (water, sewer, gas, electrical & telecommunications)

[0007] F. all drilling industries

[0008] This application pertains to all tooling used in the above industries where wear of tooling occurs. The use and application of Technogenia® will greatly extend the wear life of all tooling.

[0009] The following listing is an example of said tooling.

[0010] 1. drill bits

[0011] 2. reamers

[0012] 3. housings

[0013] 4. sond housings

[0014] 5. rods

[0015] 6. blades

[0016] 7. collars

[0017] 8. hex collars

[0018] 9. lead rods, tool adapters, buckets, shanks, subs

[0019] 10. all roller cones, tri-cone bits, single roller cone, hole openers, drag bits, mud motors,

[0020] The process of applying Technogenia® can be obtained from the manafactuer or any one of the distributors.

[0021] I claim the use and application of Technogenia® along with all other products associated with it will significantly enhance tje performance of any tooling it is applied to. The use when compared to all know products and techniques of hardsurfacing/hardfacing currently available will far surpass any know product currently available.

[0022] The following listing are other products associated with Technogenia® and can/may also be used and applied in this application.
