DTH drill bit models and size specifications tableDTH drill bit is a drilling tool used in underground engineering, rock mining and other fields. YK drill models and size specifications are diverse to meet different operational needs. The following are some common DTH drill bit models and size specifications:
The design forms of DTH drill bit mainly include end face convex type, end face flat type, end face concave type and end face deep concave center type.The choice of carbide usually includes ball teeth, spring teeth or ball teeth and spring teeth.DTH drill bit models include but are not limited to:B32/Ф32R32, R32/R38, R32/T38, etc., with medium hard tooth surface, good wear resistance and long service life.3 inches, 4 inches, 6 inches, 8 inches, etc., suitable for DTH impactors with different wind pressures.DTH drill bit size specifications cover a variety of specifications from small to large, for example:M3 drill bit: total length 65mm, shank diameter 6.4mm, blade length 35mm, small diameter 3.4mm, large diameter 6.4mm.M4 drill bit: total length 75mm, shank diameter 8.4mm, blade length 42mm, minor diameter 4.5mm, major diameter 8.4mm.M5 drill bit: total length 85mm, shank diameter 10.4mm, blade length 50mm, minor diameter 5.5mm, major diameter 10.4mm.M6 drill bit: total length 90mm, shank diameter 12.0mm, blade length 53mm, minor diameter 6.6mm, major diameter 12.5mm.Choosing the appropriate DTH drill bit model and size specifications requires considering the specific needs of the operation, such as drilling depth, rock hardness and other factors. In addition, the material and manufacturing process of the drill bit are also important factors affecting its performance and service life.
