MINING

 

Tungsten Carbide Mining Products are subjected to very severe working conditions, against heavy natural odds. Here the quality of Rapicut products is put to real test which it passes with flying colors. Rapicut has introduced different mining grades to suit Indian Geological conditions. Our mining grades are designed to work efficiently in various formations like Granite, Basalt, Sandstone, Quartzite and even in soft formation like Lime and Coal.

DRILL STEEL INSERTS
Rapicut Drill Steel Inserts (D S Inserts) are brazed on Integral Drill Steel Rods to drill the hole for blasting. Rapicut has successfully designed and developed the grade which gives longer life, greater reliability and increased fatigue strength. Rapicut is the Market Leader in India for quality DSI.

OCTAGONAL/ SQUARE INSERTS  

Octagonal and Square Inserts are used in Core Bits for Rotary drilling in exploration work. Rapicut has established itself as a leading supplier of these products. These inserts are manufactured in various sizes with 10 or 15 degree rakeangle.

Rapicut has a special grade for these Inserts which offers faster penetration rate and failure-free service.

TUNGSTEN CARBIDE BUTTONS

Rapicut has developed Tungsten Carbide Buttons in various grades suitable for use in products like Down The Hole Drilling Bits, Tricon Rock Roller Bits, Special bits required for underground cable laying, etc.

Rapicut can supply the buttons in ground and tumbled finish which facilitates perfect fitting in shank.

BWE INSERTS

To mine Brown Coal or Lignite from open cast mines a special technique called Bucket Wheel Excavation (BWE) is used. The wheel of excavator is provided with buckets which have sharp teeth to rip the soil and excavate the sediment. Rapicut has developed a grade which is highly wear resistant and tough enough to withstand any impact loading.

CARSET / CROSS BIT INSERTS

Modern Rock Drilling operations place ever increasing demand on the drilling tools. The life of Drill Tools depends on the right carbide grade.

Rapicut has developed grades for Carset/ Cross bits, 4-Point Bits, Retrac Bits and many other types. Each insert and grade is specially designed to meet stringent performance requirements.

FLOW BEANS / NOZZLES

Flow Beans are specially designed nozzles used with Rock Roller or Tricon Bit for passing liquid media at high pressure for flushing of drilled holes.

Rapicut Tungsten Carbide Nozzles are designed to suit Indian Geological conditions. It's complex internal profile is the result of application of sophisticated technology.

Other applications of the Nozzles are in oil-fired furnaces, sand blasting machines, shot peening machines, chemical handling equipments, ceramic tile manufacturing, etc

 


OTHER MINING PRODUCTS

Rapicut as a technology driven organization always tries to develop various Tungsten Carbide Products required for mining application e.g. Coal Cutting Tips, Cutter pick inserts required in Anderson Shearers, Pineapple Bit for oil exploration, Dosco Dint and Dosco Road header.
