Best drilling head/teeth design. for gravel?
Hello, im starting new buisness in well drilling, in my city we drill up to 13 meters by hand using 159mm pipes with teeth at end and extract rock and gravel from middle of those pipes using some kind of one way valve bucket pipe.
My question to community is what is best design for end of pipe teeth that would with back and forth motion pull gravel in middle of the pipe so it can be extracted, while avoiding pusing rock to outside of pipe.
I dont know how this type of drilling is called but i will add some picture to give you better idea, also i will post picture of teeth of one of my commpetitor so you can know what i am talking about.
