detailed

Long skirt drill bit made with high quality of raw material through special heat treatment, especially, tungsten carbide of tapered button bits widely applied in Hand Hold ( short-hole) drilling system for dimensional stone quarrying.

 

The height of the drill bit for shorts body is generally 50-55mm; The height of Long skirt drill bit is generally above 60mm.

Taper Angle (Degree): 4°46′,7°,11°,12°

Dia.: 28mm,30mm, 32mm, 34mm, 36mm, 38mm, 40mm, 42mm, 46mm, 48mm, 50mm, 55mm, 60mm70mm, 80mm

Drillers choose tapered button bits for faster drilling penetration rate. Different taper sizes have different characteristics when it comes to the "knock-off" index - the smaller angle will prevent the bit from spinning.

 

Performance

1. Long skirt drill bit 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

 

Application

Long skirt taper button bit is used for tunneling, mining, quarrying, Well drilling, mining drilling, ore drilling

• Suitable for small hole range
