MAXDRILL Down The Hole Bit

Becauseof economy and powerful drilling capacity, down the hole hammer become an advanceddrilling tool for drilling and mining industries. Down the hole hammers anddrill bits are designed together to work in perfect unison, giving highpenetration rates, long service life and low costs.

Advantage:

1. Deliver maximum energy to drillingbit, fast drilling speed and low air consumption due to the special innerstructure of DTH hammer designed according to newest rock drilling theory.

2. Smooth performance and longservice life of DTH hammer due to high quality alloy steel materials andadvanced processing technology adapted.

3. Low problem rate and easy tomaintenance due to simple, reliable and easy assemble and disassemble innerstructure of hammer.

4. Easy to depart bit from hammerdue to multihead thread connecting chuck and cylinder of hammer.

5.Interchangeable with DTH bit and drill pipe
