Smalll Hole Rock Drill Bit Tapered Button Mining Drill Bit 7°11°12° Tungsten Carbide

Smalll Hole Rock Drill Bit Tapered Button Mining Drill Bit 7°11°12° Tungsten Carbide

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.

Feature of the taper button bit:

1 Tapered button bits connect with tapered drill rod perfectly for drilling holes
2 Stable and mature welding technology ensure high quality of bits
3 Accurate dimension of taper degree perfectly matches the rods
4 work reliable and very cost-effective

5 High grade tungsten carbide inserts
6 Bit bodies manufactured from high grade steel and processed using state-of-the-art CNC machinery and heat treatment

We can design and manufacture according to customers' samples or drawings of the Bit Dia., No. of air / water holes, carbide button shape and the face shape. Our button bit is made with high quality of best quality alloy steel bar and tungsten carbides, through heat treatment so that it can withstand the toughest rock drilling demands, and transmit intensive impact energy into the rock with the least possible loss of energy. Comparing with tapered chisel bits and tapered cross bits, button bits has higher technology, much longer primary drilling time and higher drilling efficiency. According to the tungsten carbideinsert, tapered button bits can be divided into the types of hemispherical, conical andparabolic button, etc.

(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

(5) Socket inside dia:15/19/22/25mm

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:

1 Tapered chisel bit

Widely used in drilling holes with depth less than 5 meters and diameter ranged in 20-45 mm by light-duty rock drill, like Y6.

2 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.

3 Tapered Button Bits

Comparing with tapered chisel and cross bits, button bits has higher technology, much longer primary drilling time and higher drilling efficiency. According to the tungsten carbide insert, tapered button bits can be divided into the types of hemispherical, conical and parabolic button.
