QKZ165-H

DINOSAW DTH drilling machines deliver 6-8m/h speeds, with hole diameters ranging from 65-165mm and depths up to 40m for stone extraction. Available in pneumatic, electric, or hydraulic power options, these machines excel in quarrying operations across diverse environments with minimal setup requirements. These DTH drillers efficiently extract granite, marble, limestone, sandstone, quartzite, basalt, and slate. Their precision ensures clean separation while reducing material waste in challenging terrains.

The DINOSAW DTH drilling range covers quarry hole preparation from Φ65 to Φ165 mm and depths to 40 m — with pneumatic, electric and hydraulic power options matched to hole diameter, rock hardness and site infrastructure.

Real Drilling Performance & Key Metrics

Hole Range

Three models cover the full quarry drilling range: the QKZ90-P and QKZ90-E drill Φ65–90 mm, the QKZ165-H drills Φ90–165 mm for larger breaking holes.

Drilling Depth

Maximum depths of 35–40 m (30 m on the large-hole model) cover bench drilling, pre-splitting and blasting hole patterns in dimensional stone quarries.

Feed Range by Hole Class

Reference feed rates of 6–8 m/h on Φ65–90 mm holes and 2–4 m/h on the QKZ165-H large holes — the hole class sets the pace, not one headline number.

DTH Impact at the Bit

The hammer works directly behind the bit at the bottom of the hole, delivering impact energy to the rock face instead of transmitting it through a long drill string — penetration in hard granite and broken formations stays high where top-hammer drills lose energy to rod vibration.

Three Drive Configurations

Pneumatic suits compressor-rich quarries with simple site infrastructure; electric suits sites with stable power lines and lower air capacity; hydraulic serves the largest holes and hardest rock with controlled feed. The drive choice follows the site, not a catalog default.

Hydraulic Large-Hole Feed

The QKZ165-H adds hydraulic feed to hydraulic rotation: controlled thrust on Φ90–165 mm holes protects drilling stability in hard or fractured rock, where uncontrolled pneumatic feed stalls or deviates.
