Tungsten Carbide Material Drill Bits For Rock And Concrete Tapered Cross Bit

Tungsten Carbide Material Drill Bits For Rock And Concrete , Tapered Cross Bit

Tapered drill bits are Ideal for small short hole drill & blast, as well as roof bolting applications, our hand-held system is comprised of premium alloy tapered hexagonal drill steels ranging from 0.5 m up to 7.9 m in length, and complimented by a complete range of reamers, blade and button bits.

(1) Taper angle: 4°,4°46″,6°,7°,11°,12°

(2) Models:chisel/cross/button bit

(3) Dia:20-45 mm

(4) Button bit shape:spherical/parabolic

Cemented carbide tapered button bit was from high quality cemented carbide, produced with advanced technology and equipment, having different types bits, such as tapered chisel bit, tapered cross bit and tapered button bit which connected with tapered drill rod well for drilling hole, inserting depth is 25-30mm, obtaining maximum drilling speed, keeping stable and lowering rock drill working parameters so that prevent single button under overload then cause the button broken or lost. Cemented carbide tapered button bits widely used in gold mining, geological drilling, railway, highway, water conservancy and hydropower, tunnel working and granite and marble quarrying.

Parameter of the taper button bit:

Tapered cross bit

Used under any rock drilling condition and mainly used for hard or very hard rock formation because of it's comprehensive adaptability. Compared with taper chisel bits, taper cross bits have a better drilling performance because of carbide tips on cross bits doubled.
