DHD 360 Bits are available in diameter range between 152-203 mm. these bits have 2 flushing holes and are available in three bit face styles: flat, concave,convex and in three carbides shape of DTH buttons: Dome, Parabolic(Semi-Ballistic), Ballistic.
DHD360 bits are produced from premium quality nickel-alloy steel for increased durability and wear characteristics. Specific heat treatment standards and special "stress relief" processes ensure
consistent performance. DHD360 DTH hammer bits are designed for maximum performance and hole cleaning ability and high penetration rate.
DTH hammer is a general purpose hammer suitable at wide range of air pressures. The hammer has few parts than other hammer allowing an easy maintenance and servicing.
Operation is suitable at air pressure of 87-435 psi (6-30 bar).
Recommended Drilling diameters is 101-127mm (4-5").
