11”IADC837 Tricone bit
Main Features of Milalion Insert Bits CUTTING STRUCTURES 1 Tailored insert shapes and grades manufactured using state-of-the-art tungsten carbide technology for different formations having varied drillability and compressive strength, to provide an optimum match between inserts wear resistance and toughness. 2. BY using computer simulation of the rock breaking at the bottom of the hole, Milalion's engineers are able to design the best inserts space to ensure the most balanced

2. BY using computer simulation of the rock breaking at the bottom of the hole, Milalion's engineers are able to design the best inserts space to ensure the most balanced load on each insert.See Figurel1
3.Double rows of gage inserts for better maintaining full gage hole. See Figure2

LUG AND SHIRTTAIL ENHANCEMENT
1,Conventional Shirttail Design(See Figure3)
Hard metal and wear resistant carbide were applied to shirttail and shirttail lip.
2,Particular Shirttail Design(See Figure4)
This shirttail features a "terraced" design, which increases escape area and the bailing velocity and decreases cuttings regrind and wear on shirttail and shirttail lip.
Hardmetal was applied to shirttail lip and lug .Wear resistant carbide on Shirttail lip and lug and around the "terrace" lower part of shirttail lug
