new 8 1/2'' 4 blades pdc bit with API

tricone bit Cutting structure: very long widely spaced ,chisel-shaped inserts and considerable cone axis offset against center line of bit ensure very high penetration rate .To secure the bit from diameter loss, the gage protection inserts have got shorter length and greater angle of the top. Formations: long intervals of very soft poorly compacted shales ,sandstone, clays, salts and soft li mestones. Size and IADC available: 3 3/4" to 26" IADC 415,435,445,417,437,517,537,617

TCI 437 soft formation tci tricone bits

The 437 tci bits are used to drill low compressive strength very soft formation tci bits maximize the use of bothconical and chisel tungsten carbide inserts of large diameters and high projection. This cutting structure design combined with maximum cone offset ,results in high bit penetration rates.the deep intermesh of cutter rows prevents bit bailing in sticky formations.

TCI 517   medium formation tci tricone bits

The 517 features aggressive chisel tungsten carbide inserts on the heel rows and inner rows this design provides a fast drilling rate and added cutting structure durability in medium to medium hard for mations the HSN rubber o-ring provides adequate sealing for bearing durability.

TCI 637 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-shaped inserts are used in all rows to provide cutter durability and long life.

TCI 617 the tci 617 features robust chisel tungsten carbide inserts on the heel row and conical on the inner rows .this design provides a fast drilling rate and added cutting structure durability in medium to medium hard formations . the HSN rubber o-rin provides adequate sealing for bearing durability .

The 114-117 soft formation tooth bits are used to drill low-compressive strength ,soft formations long projection tooth lengths are used on high offset cones to provide the greatest penetration rates possible. Wear-resistent hard facing is used to control tooth wear. On the softest bit types this hard facing completely covers the bit teeth.

The 127 medium – hard formation tooth bits

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.
