Large Drill Bits Drill Spare Parts Carbon Steel For Mining Water Well Drilling
Description
DTH drill bits are widely used in underground mining, quarries, hydraulic and Hydro-Power Engineering,
water well drilling, Mineral exploration, anchoring hole drilling, geothermal engineering, Subway excavation,
another civil engineering. it has the advantage of high flatness, smooth hole wall, high rigid of drill rod and
hammer, independent of high axial thrust, no limit of drilling depth, low cost of devices and easiness to maintain.
Application
DTH drill bits range covers the most diverseapplications in mining, natural resources exploration, water wells,
quarries and civil works.
Product Information
JCDRILL has a comprehensive range of DTH drill bits to match all conceivable applications. Each bit is made from quality alloy steel, and has been precision machined to produce a perfect body, heat treated to the required hardness, given surface compression for fatigue resistance, and fitted with precision buttons manufactured in-house. These are deigned for specific applications for all rock types, hardness's and condition. Bit life and rate of penetration are the most important criteria in selecting the right bit for a particular application.
specification
JCDRILL Button Bits range covers hole diameter 3" and upwards upto 24". JCDRILL DTH Button Bits are
available for all Major DTH Hammer Brands.

Advantages:
1. Computer analysis and laboratory trials have been used to optimize the number of buttons as well as
their size and positioning throughout the bit front.
2. Carbide has been carefully designed to minimize the risk of button loss and button failure
3. The design of the bit body and the frontal sludge grooves provides uniform flushing with reduces steel
wash on both bit and the hammer.
4. Material processes and multiple heat treatment have focussed on achieving maximum resistance to fatigue failure.
