The Mid-Western S83 Demon Drill is a heavy-duty pneumatic rock-drilling unit adapted from the well-known S83 rock-drill platform. Specifically configured for automated or feed-mounted drilling (rather than purely handheld jackleg use), the Demon Drill retains the rugged performance of the S83 with enhancements for reduced operator fatigue and high productivity.
Design:
- A 3 (76 mm) diameter piston and 2.5 (64 mm) stroke, giving high impact energy per blow.
- Overall length of approx. 27¼ (688 mm) and weight of about 72 lb (32.4 kg) in standard configuration.
- Designed for feedsystem mounting: the Demon Drill version includes mounting options (receiver hitch or plate mount) and ability to tilt/lock up to 30 left or right.
- Pneumatic operation including percussion (hammering) and rotation, allowing high speed rock drilling (with ~2,300 blows per minute at 90 psi) in rock or aggregate applications.
- Large hose size (1 air, ½ water when wet flushing) to support heavy duty airflow and flushing requirements.
- Robust OEM heritage: Mid-Western acquired the S83 design and continues to manufacture it to Gardner Denver specs, ensuring depth of spares and service.
From an aesthetic and userinterface standpoint, the Demon Drill is optimized for minimal operator fatigue: mounting on a feed system means the operator no longer must support the entire tool weight; adjustability of tilt and locking helps in awkward hole locations; and the balanced weight distribution improves controllability. The build uses heavy iron/alloy steel components designed for continuous operation in mining, quarrying, construction or geotechnical environments.
Applications:The S83 Demon Drill is particularly suited for highvolume or highthroughput drilling tasks where reliability, penetration rate and minimal operator fatigue are priorities.
- Surface or underground mines and quarries, where multiple holes need to be drilled quickly in rock or blast holes.
- Geotechnical drilling operations (exploration, anchor holes, ground stabilization) where a feedmounted rock drill reduces manual labor.
- Jacking or grouting operations, utility companies, road crews, fencing contractors the feedmounted design allows drilling of holes for anchors, postdriving, boreholes for fencing or row structures.
- Construction projects involving heavy rock drilling, foundation anchorage, pilot holes in hard rock or concrete where a robust drill is required.
- Also suitable for use in feed leg systems, rotary feed rigs, or crawlermounted drilling rigs, where the Demon Drill serves as the rockdrill head on the feed.
In short: this is not a light duty handheld drill; it is a highimpact production rock drilling unit optimized for feed or jacked rigs, where high productivity and durability are essential.
