G250 Jackleg Drill: The S250 Equivalent Built for Underground Hard Rock Mines
What Is the G250 Jackleg Drill?
The G250 is a pneumatic jackleg rock drill engineered for demanding underground mining environments. Built as a proven equivalent to the The S250, it is designed to perform in confined spaces and challenging orientations — drilling at multiple angles while delivering consistently high penetration rates and strong torque output, even at low air pressure.
Whether you are developing drives, drilling blast holes in stopes, or preparing ground support in a narrow-vein operation, the G250 is built to keep up with the pace of a hard-working underground crew.
Key Benefits of the G250 Jackleg Drill
- High penetration rate and strong torque even at low air pressure
- Minimum downtime and low maintenance cost
- Ergonomic controls integrated into the drill backhead for maximum safety and comfort
- Pusher leg controls with push button jackleg retraction
- Motorcycle control feed for intuitive, fatigue-reducing operation
- Available in multiple configurations — sinker, stoper, and jackleg
- Market leader in North & South America
- Parts interchangeable with Boart Longyear S250 jackleg drill
Engineering Details That Set It Apart
Large Contact Areas for Longer Component Life
The G250 is engineered with large contact areas between major cylinder components. This design reduces impact pressure on individual parts during each percussion cycle — directly extending product life and reducing the frequency of component replacements in high-utilization underground environments.
Integrated Pusher Leg Controls
Unlike competitors where the pusher leg operates as a separate system, the G250's pusher leg controls are fully integrated into the drill backhead. This gives the operator complete machine control from a single ergonomic position, reducing physical strain and improving drilling accuracy — particularly during inclined or overhead drilling tasks.
GP755A Pusher Leg — Three Feed Length Options
The G250 comes packaged with the GP755A Pusher Leg, purpose-designed for this drill. Three feed length options are available to suit different heading heights and drilling orientations:
The balanced weight distribution of the GP755A ensures easy operator control during long drilling shifts. Its push button jackleg retraction and parts interchangeability with the Boart Longyear A755 Pusher Leg give mine operators maximum flexibility in their spare parts procurement.
G250 vs S250: Why Choose the GME Equivalent?
- Full S250 Compatibility: The G250 is a direct equivalent — all critical operating specifications match the S250 Jackleg Drill, making it a seamless replacement with zero rig modifications required.
- Parts Interchangeability: Components are interchangeable with Boart Longyear S250 and A755 Pusher Leg, simplifying your spare parts inventory and reducing procurement lead times.
- Multiple Configurations: Available as a jackleg, sinker, or stoper — one platform, three applications, covering the full scope of underground drilling tasks.
- Competitive Pricing: GME combines OEM-equivalent engineering quality with competitive pricing, delivering a lower total cost of ownership across the equipment's service life.
- Global Support: Backed by GME's worldwide distribution network and technical support team, the G250 keeps your operation running regardless of where you mine.
Who Is the G250 Built For?
The G250 Jackleg Drill is the right choice for underground hard rock mining operations running jackleg drilling programs in development headings, stopes, and raises. It is particularly well-suited to:
- Narrow-vein gold, silver, and base metal mines in North and South America
- Operations currently running S250 jackleg drills looking for a cost-effective equivalent
- Mine sites requiring multiple drill configurations (jackleg, stoper, sinker) from a single platform
- Contractors and mining companies prioritising low downtime and easy maintenance
As the market leader in North and South America, GME's G250 is proven in the toughest underground conditions — and trusted by miners who cannot afford downtime.
