Frequently Asked Questions

Common Questions Answered

Find answers about our products, ordering process, and technical drilling applications.

What sizes of DTH Hammers does Hari Chandana Enterprises supply?

We supply DTH Hammers ranging from 3 inch to 10 inch diameter. This covers applications from small-diameter water well drilling to large-diameter blast hole operations in mining. Please contact our team for specific size availability and current lead times.

What types of Button Bits are available for different rock formations?

We offer spherical button bits for softer formations, ballistic button bits for medium to hard rock, and flat-face bits for specific applications. Our team can advise on the best button shape and carbide grade based on your specific rock type, whether granite, basalt, limestone, sandstone, or mixed formations.

What materials are used in the DTH Hammers and Button Bits you supply?

Our DTH Hammers are manufactured from high-strength alloy steel heat-treated for durability under high-impact conditions. Our Button Bits use premium-grade tungsten carbide inserts offering excellent hardness and wear resistance. Steel bodies are similarly crafted from quality alloy steel for extended service life.

Are your products compatible with major DTH drilling rigs available in India?

Yes. Our DTH Hammers and Button Bits meet standard industry thread profiles and dimension specifications, compatible with widely used drilling rigs from major brands in the Indian market. For specific compatibility requirements, share your rig specifications with us and we will confirm before dispatch.

Do you offer customized product specifications based on project requirements?

For specific diameter requirements, thread profiles, or application-specific configurations, we can accommodate customized requests through our supply network. These orders may carry slightly longer lead times depending on specifications. Contact Mr. Ravi at 8088073661 to discuss custom requirements in detail.

How do I place an order with Hari Chandana Enterprises?

Call or message Mr. Ravi at 8088073661, or use the enquiry form on this page to share your product requirements. We send a quotation within a few hours on business days. Orders are confirmed upon receipt of your purchase order or written confirmation.

What is the typical lead time from order to delivery?

For standard products in stock, we dispatch within 24 hours of order confirmation from Bangalore. Transit times depend on delivery location. Karnataka destinations typically receive within 1 to 2 business days. Other states generally take 2 to 5 business days depending on logistics coverage.

Is there a minimum order quantity requirement?

We do not enforce strict minimum order quantity restrictions. We understand that different operations have different procurement cycles. Whether you need a small batch for a specific project or a bulk order for ongoing operations, contact us and we will provide pricing and options accordingly.

Do you supply to locations outside Bangalore and Karnataka?

Yes, we supply clients across India. We have dispatched products to Maharashtra, Andhra Pradesh, Telangana, Tamil Nadu, Rajasthan, and other states. Our logistics partners cover most major industrial zones. Freight charges for outstation deliveries are discussed at the time of quotation.

What payment terms are available for B2B clients?

For first-time buyers, we work on advance payment terms. For established clients with a track record, credit terms can be discussed based on order history. Payment is accepted via bank transfer, UPI, or other standard B2B methods. Speak to Mr. Ravi for payment term discussions specific to your situation.

How do I select the right DTH Hammer size for my drilling application?

Hammer selection depends on required borehole diameter, available air compressor capacity (CFM and working pressure), and rock hardness. A general guideline: 3 to 4 inch hammers for water wells and exploration; 5 to 6 inch for quarry and medium mining; 8 to 10 inch for heavy blast hole drilling. Contact our team with your site conditions for accurate recommendations.

What factors affect the service life of Button Bits in field conditions?

Button bit life is influenced by rock abrasivity, operating air pressure, penetration rate, bit rotation speed, and flushing quality. Overfeeding or insufficient flushing leads to early failure. Using a bit grade too soft for the formation accelerates wear. Proper matching of bit to rock type, combined with correct operating parameters, significantly extends service life.

Can DTH Hammers be used for drilling in soft formations or clay-rich ground?

DTH drilling is most effective in consolidated rock. For soft formations, overburden drilling systems or rotary methods are generally more appropriate. When projects involve overburden above hard rock strata, DTH systems are deployed once the drill string reaches the rock zone. Contact us to discuss whether DTH tooling suits your ground conditions.

What air compressor specifications are required for DTH Hammer operation?

Required compressor specs depend on hammer size. A general reference: 3 to 4 inch hammers require 200 to 400 CFM at 100 to 150 PSI; 5 to 6 inch typically need 400 to 700 CFM; 8 inch and above may require 900 CFM or more at higher pressures. Always use a compressor rated at or above the minimum specification for efficient operation and adequate flushing velocity.

How should DTH Hammers and Button Bits be stored when not in use?

Store in a dry, covered environment away from moisture. Before storage, clean internal components and lightly oil hammer internals to prevent corrosion. Cover thread connections with protectors. Button bits should be kept clean and free from heavy objects that could damage carbide inserts. Regular inspection before and after use extends tool life significantly.
