We offer a range of smart drill rigs for handpump boreholes with the following features:

• High pull back force offered is readily achieved. This is because they do not rely on the weight of the rig due to the rear jack and drilling centerline geometry.
• Performance of the Rig depends on the size of the compressor used. The rig air system is designed to operate with the most efficient mobile compressors available internationally.
• Two alternative drill heads are offered: a single speed drill head is standard and a 2 speed drill head is available as an option where a need for higher speed rotary drilling is required.
• Noted for their precise and advanced drilling control, these Rigs have made good drillers out of many an inexperienced operator.

VALUE FOR MONEY - Return on Investment is quicker when compared to high initial cost of Bigger Drilling Rigs.

Our expertise in the highly demanding water well drilling application in a variety of difficult strata have enabled us to tropicalise screw compressors to full load conditions. Our range of Engine Driven Mobile Air compressors (trolley mounted) are designed to withstand extremes of temperature, dust and tough operating conditions - from the deserts of Sahara to the Highlands of Ethiopia.

Features:

• Elegant & Energy-Saving Design: The heart of the Screw Air Compressor is the Air-End, engineered for optimum performance and economy in operation. The energy-saving asymmetrical screw type rotors, mounted on anti-friction bearings, rotate at conservative speeds, compressing pulsation-free air in between lobe –flute spaces. Oil is continuously injected for cooling, lubricating and sealing between rotor tips and casing. Since the rotors do not touch each other, there is virtually no wear and tear.
• Reliable Prime Mover: A choice of rugged diesel engines known for their performance and well accepted in the market.
• Low oil consumption: 2 Stage Air/Oil Separator effectively separates oil from air. Oil is fed back into the system for economical operation.
• Air delivery matched to demand: The 0-100% ‘stepless’ variable capacity control reduces fuel consumption and operating costs. Air consumption at the user-end controls the opening and closing of the inlet valve, thereby regulating inlet air suction, and matching engine speed to demand, thereby saving on fuel. You pay only for the air you use.
• Easy Maneuverability: Our compressors are mounted on rugged trolleys, designed to meet the exacting demands of the construction and mining industry. So you can maneuver them even in the toughest terrains in India and abroad.
• Low maintenance costs: VAISHNO’s reliability with proven design and economical spare parts keep your operating costs to the minimum.

VAISHNO’s DTH Hammers are manufactured to Global Standards, from the best available Alloy Steel, machined to high precision and high standards. All the components are heat-treated in state of the art fully process controlled facility. VAISHNO Hammer parts and bits are "Shot-Penned" (a stress relieving process) on both inside and outside to add further durability. The carbide buttons that are used are sourced from reliable manufactures of International repute.

• Longer life even under difficult drilling conditions
• Higher and consistent penetration rate
• Capable in performing without any trouble at high pressure ranges (80-350 PSI)
• Less moving parts, and compact structure for lower wear & tear
• No ‘back hammering’ & blockages.
• Less maintenance costs

Sizes 3 inch, 4 inch, 6 inch & 8 inch

A set of Fast-Wearing Parts are supplied with each hammer.

VAISNO’s Button Bits are designed to suit all major DTH Hammer brands. Made of superior quality raw material, our Button Bits are tough, durable and work with precision and accuracy while penetrating into the sub-soil formation of varied nature. High Quality material processing and Multiple Heat Treatment imparts maximum resistance against fatigue. This special process also includes "Case Hardening", "Thru-Hardening", ''Double - Tempered'' Heat Treatment in sophisticated Seal Quench Furnaces for total consistent strength. The design of the Bit body and the Frontal Sludge grooves provide uniform flushing, which reduces steel wash on both bit and the hammer.

Size Range from 4 inch to 14 inch, in various shapes such FLAT, CONCAVE & CONVEX.

All our Bits are compatible with all Brands of Hammers used around the world.

Rotary type Drag Bits are used for the same manner and for the same purpose as milled tooth Rock Bits, except that they are limited to softer formations generally. They are, in most cases cheaper than Rock Bits. The cutting profile may be flat, chevron or stepped according to application. They may be used in air or fluid flush. When ordering Drag bits please ensure that the following information is clearly provided:

1. Type of Sub-Soil Formation to be drilled
2. Flusing Medium (Air or Fluid)
3. Profile of the Drag Bit (Flat, Stepped or CHEVRON Type)

Sizes Available: 4 inch to 18 inch

Suitable Subs are supplied by us to suit different Drill Stems.

Manufactured from superior quality raw material and finished to perfection. The rock roller bits that we deal in are available in 4" to 17" , steel tooth and TCI(tungsten carbide insert) bits for blast and water well drilling, our product is highly durable and long lasting in nature. It is available in distinct face designs such as flat, concave & convex for better result.
