Our oilfield keychain bits have: Turning cones on bearings Grease Caps, Air jets & tapered api threads! These Oilfield Keychains are 100% hand machined on a lathe and end mill from a solid piece of brass and then finish plated. That is why the details are so perfect and crisp. True Machined Bits! Others simply "cast" theirs and call them machined. ate

Great gift!
Overall the design is pretty spot on to a real tri-cone bit! I’m very happy with my purchase! Would make cool little gifts for your oilfield friends or family. Prob have some point out the flaws for instance the cones spin but there a little loose or something in that nature.... it’s a keychain!! For looks!! But mine looks great I love it! Thanks amazon!

NOT From John H. Martin Company - CHEAP COPY FROM CHINA
This is a cheap copy from China - Beware it is not from the John H. Martin company as stated. The John H. Martin Company is my business. This is false advertising? These drill bits do not even come anywhere close to our quality which has remained the same since 1937. China bits have loose cones that fall apart.

Not a John H Martin Co product
These are cheep China made key chains. The description is even taken for the John H Martin Co website. These are not machined. They are cheap cast products. I have known the John H Martin Co since the 1970's. They would never sell this poor of a quality product. Go to the John H Martin Co website if you are looking for quality.
