HENGLONG drill can produce button bit grinding machine and diamond grinding cups and grinding wheels for blunt carbide button sharpening for extension drilling life by 20-30%. Never have to persevere with blunt drill heads again. The height of the short skirt button bit is generally 50-55mm

HENGLONG drill taper button bit as small hole bit is different with thread button bit as long hole bit to use taper match with bit with rod to be used for air leg or hand held jack hammer driller in quarrying,and mining. to match YT24, YT28, YT29A air pusher rock drills. such as Peru, Chile, Colombia etc. most of main size as follow:

Carbide code: T6 grade ( world No.1 ) Designed for underground mining to match YT24, YT28, YT29A air pusher rock drills in Peru, Chile, Colombia, UK.

 

1. Short 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
