TEAMWHOLE 4INCH DTH HAMMER
Teamwhole manufactures wide range and most efficient Down-the-Hole (DTH) hammers and bits for the mining blasting,water well especially deep well drilling,foundation construction etc.Our prodcuts trust by drilling contractor becasue of the advantages
Features
1.Piston produced with high nickel steel,adavnce heat treatment,ensure the hammer long service
2.Designed under real platform testing,then will know what's the frequency and impact power the DTH hammer transfer to DTH bits
3.Advanced CNC machine ensure DTH hammer every parts smooth srface,ewer parts and easier maintenance.
4.Geater productivity, extrax-short structure,can ensure DTH hammer increase efficiency, more power, and faster penetration.
