Volga Burmash manufactures a wide range of hard-alloy products on request. Its published hard-alloy product list comprises: chisel-shaped and conical tungsten carbide inserts (80+ sizes); journals (thrust buttons) of various designs; carbide plates; stems (rods) for drills; jet nozzles; bushings; carbide wire-drawing dies; hard-metal balls; studs for studding winter tires; granular hard-facing (alloying) material for bit bodies and edge tools; press tooling parts; and bearing segments for drill-pipe fixation.
Grades, dimensions and other technical parameters are not published in the VBM product list. Send your drawing or requirements to VBM Guyana and we will obtain a quotation from the manufacturer.
Much of Guyana's gold sits in the greenstone belts of the hinterland — quartz veins and altered volcanics that are unusually abrasive and hard on a cutting structure. That ground punishes a brittle, high-hardness insert: micro-chipping at the tip blunts the bit long before the carbide wears out evenly. For VBM bits working this rock, the cutting structure is chosen by IADC code: tungsten carbide insert (TCI) series for medium to hard, abrasive formations.
Air-flush roller cone bits for rotary blast holes are covered under Mining & Blast-Hole Bits, oil and gas TCI roller cone bits sit under Tricone Bits, and the jet nozzles, nozzle wrenches and bit breakers for VBM bits are listed under Accessories. For carbide parts made on request, tell us the part, drawing and quantity and we will request a quotation from VBM.
Tell us your hole size, formation and target depth. As the authorized Volga Burmash distributor in Guyana, we'll match a tricone, PDC or mining bit and respond with availability and pricing.
