Blasting Drill
Product Summary

The SMC-DTH-452H crawler hydraulic down-the-hole drilling rig has a fully optimized structure, lower footage cost, and more user-friendly design. It uses a diesel engine (motor)-hydraulic oil pump group as the power unit, and the hydraulic motor realizes auxiliary actions such as drilling rig rotation, propulsion, lifting, walking, and hydraulic cylinder swing angle positioning.

Mainly used for drilling and blasting hole operations in hydropower projects, open-pit mining, road construction, and national defense projects.

Distinctive Features
Powerful Drilling Performance

The Blasting Drill delivers high torque and stable drill feed to penetrate tough rock surfaces with minimal deflection. This ensures accurate hole alignment every time.

Heavy-Duty Construction

Its reinforced drill frame and industrial-grade components provide extended service life under harsh field conditions and continuous drilling cycles.

Precision Hole Placement

Designed for accurate depth control and consistent hole spacing, this blasting drill helps improve blast efficiency and reduces the risk of misfires or incomplete fragmentation.

Efficient Rock Penetration

A powerful drive mechanism and robust drilling bit support rapid penetration, enhancing overall operational productivity.

Operator-Focused Design

Ergonomically positioned controls and simplified adjustments allow technicians to set up and operate the blower with ease, improving on-site effectiveness.
