Blast Hole Drills are self-propelled machines that drill downward (creating holes in rock) to charge explosives for blasting. Collectively referred to as Blast Hole Drills, they encompass crawler drills, down-the-hole drills, and rotary drills. In open-pit excavation sites like mines and quarries, Bast Hole Drills create holes to blast rock and extract stone. Used widely in Japan and overseas, they contribute to the mining of crushed stone and limestone (raw materials supporting infrastructure development), non-ferrous metals (gold, silver, etc.), and iron ore. The amount of explosives used varies depending on the size of the drilled hole, which in turn affects the quantity of rock produced after blasting. Since the size of the Blast Hole Drill depends on the diameter of the hole that is needed, consider the production scale when selecting the appropriate size.
Hydraulic Crawler Drills
In 1977, we developed Japan’s first hydraulic crawler drill. It has since undergone model changes and has expanded into the HCR Series of hydraulic crawlers, which are used by customers both in Japan and overseas.
The latest lineup features the HD800 Series Drifter. By maintaining optimal drilling conditions in response to constantly changing rock conditions, this drill easily enables accurate, speedy drilling with minimal hole deviation.
Features
-
iDS (Intelligent Drilling System)
iDS automatically controls drilling to maintain optimal conditions regardless of changes in the rock quality, supporting smooth drilling.
-
iMS
(Inteligent Monitoring System)Monitors and centralizes the display of machine operating status and maintenance information.

Attachment Drill (AHD709)
It is an attachment drill that can be attached to hydraulic excavators. If customer wants to increase drilling efficiency at a site where a pneumatic drill is used, or if a bench is not stable at the initial development of a stone quarry, drilling can be performed over a wide area. Equipped with the proven HD709 drifter.
Features
-
Powered by FRD HD709 Hydraulic Drifter
-
All hydraulic equipment is housed in the attachment drill box and receives oil pressure from the hydraulic breaker piping.
-
Drilling is performed by a wired controller. The controller is lightweight and simple to operate.

Down The Hole Drills
A Down-the-Hole Drill is a machine that uses a down-the-hole hammer to drill larger blast holes than crawler drills. It is used in large-scale limestone mines and similar applications.
In addition to excellent drilling capability, this drill excels in mobility, operability, durability, cabin comfort, and maintainability.
Features
