1.Tighten the bits when screw on.
2.When the bit lower down to the bottom ,
Should give a soft pressure, slow drilling .After a drilling 0.2m-0.3m with appropriate pump, then give the conventional drilling.
3.Drilling could not be without water, if not fear the normal vibration sound or drill too slow, lift the drill to check without delay.
4.When drill jammed, withdraw first, should not to force the rig start.
5.Drill could not without water, to ensure that the bit will be too hot.
6.Use the bits in right order , big size first, then small one .
The Incinerated scrap or E46, is the by-product derived from the reprocessing of incinerated domestic waste.
After the combustion process, the furnace output (IBA Incinerator bottom ash) is firstly washed, magnetically separated and screened to separate any no ferrous material.
At a visual inspection, the material is fragmentized, with iron and steel parts, resulting partly cut or in shredded form.
The stock appears heterogeneous and contains all kind of cut or dismantled steel parts such as sheets, bars, frames, wires, bolts and other iron/steel household residues.
The incinerated scrap is eventually oxidized, due to the thermal and cooling treatments, that the material has been submitted to. The burnt scrap also contains minor slag parts, ash and iron oxide, due to the recovery process.
Such components are inherent and adhere to the scrap surface. The total impurities, can be sorted, but not fully removed.
The consignment does not contain any type of arms, ammunition, mines, shells, cartridges, radioactive contaminated, or any other explosive material in any form either used or otherwise.
The collected stock, is stored in open air, on cemented flooring. It can be loaded loose in 20â?? heavy duty container.

API-7-1 Standard rock bit tricone bit TCI Tricone Bits inserted tooth
1.Cutting structure this type TCI tricone bits:
The durability of premium tungsten carbide insert is improved with new formulas and new techniques for insert bit.
2.Gauge structure this type TCI tricone bits:
Multiple gauge protection with gauge trimmers on the heel of cone, tungsten carbide inserts and hardfacing on the shirttail increases gauge holding capability and bearing life.
3.Bearing structure of this type TCI tricone bits:
High precision bearing with two thrust faces. Ball lock the cone. Hardfaced head bearing surface. Cone bearing inlaid with friction-reducing alloy and then silver-plated. Abrasion resistance and seizure resistance of the bearing are improved.
4.Seal and Lubrication of this type TCI tricone bits:
Premium O-ring, optimal seal compression and curved seal structure can enhance the seal performance. The pressure compensator system and advanced grease can greatly increase the lubricating reliability .
5.Product Application this type TCI tricone bits:
It can receive high WOB in the conventional drilling. It is suitable for various formations by matching cutting structure with different tooth shape, tooth density and tooth exposure height.
9 be used for water well, oil field, underground, construction, geothermal, directional boring
114-117, 127
Soft Formation Tooth Bits
The 114-117 bits are used to drill low-compressive strength, soft formation. Long projection tooth lengths are used on high offset cones to provide the greatest penetration rates possible. Wear-resistant hard facing is used to control tooth wear. On the softest bits type this hard facing completely covers the bit teeth.
127
Medium-Hard Formation Tooth Bits
The 127 bits are used to drill high-compressive strength, medium hard formations. Short projection teeth with reduced crest length are used in this series of bit designs. Durable hard facing is applied to reduce tooth wear.
437
Soft Formation TCI Tricone Bits
The 437 TCI bits are used to drill low compressive strength, very soft formations. TCI bits maximize the use of both conical and chisel tungsten carbide inserts of large diameters and high projection. This cutting structure design, combined with maximum cone offset, result in high bit penetratione rates. The deep intermesh of cutter rows prevents bit bailing in sticky formations.
517
Medium Formation TCI Tricone Bits
The 517 features aggressive chisel tungsten carbide insert on the heel rows and inter rows. This design provides a fast drilling rate and added cutting strcture durability in medium-to-medium hard for-mationes. The HSN rubber O-ring provides adequate sealing for bearing durability.
637
Hard Formation TCI Tricone Bits
The 637 bits can be used to drill hard and abrasive forma-tions. Wear-resistant tungsten carbide inserts are used in the outer rows to prevent loss of bit gauge. Maximum numbers of hemispherical-durability and long life.
617
Medium-Hard Formation TCI Tricone Bits
The 617 feature robust chisel tungsten carbide inserts on the heel row and conical on the inner rows. This design provides a fest drilling rate and added cutting structure durability in medium to medium hard formations. The HSN rubber O-rin provides adequate sealing for bearing durability.
