Summary information：Custom made conventional size trenchless rock pallet
Classification：Tooth wheel palm

The dental wheel palm includes insert and milled tooth palms. They are cut from oil-sealed and non-sealed bits and can be used in all kinds of hard strata. It is a drilling tool for urban trenchless construction and pipe-laying.
Suitable formations for milled tricone drill bit:
1 . Soft to medium formations of low compressive strength
2 . Medium to hard formations with high compressive strength
3. semi-abrasive and abrasive hard formations
4. Highly abrasive hard formations
With the in-depth use and development of the tricone drill bits, it has shown extraordinary results in several fields! Here we briefly describe the exploitation of the dental wheel palm piece!
Product characteristics various types of insert tooth wheel palm.

1. The bearings are high precision mating radial sliding, two way thrust bearings.
2. High precision rubber seals are used.
3. Steel ball locking tooth wheel to adapt to high speed.
4. Adopting full rubber reservoir bladder which can limit the differential pressure and prevent drilling fluid from entering the lubrication system, providing a good lubrication guarantee for the bearing system.
5. A new type of grease that can withstand high temperatures of 250°C and resists wear is used.
6. The high strength and high toughness carbide teeth are used in the inserted drill bit. The optimized design of the number of tooth rows, number of teeth, height of exposed teeth and the unique shape of the alloy teeth give full play to the high wear resistance and excellent cutting ability of the inserted drill bit.
