The Ground MILLHOG is a right angle, I.D. clamping beveling machine that is only 1.5in (38.1 mm) wide and fits between boiler water wall tubes for beveling a single tube and other boiler tube applications with restricted access. The Ground MILLHOG is made of high quality treated materials for durability. Proprietary bearings support heavy duty gears for smooth operation on the toughest applications. Patented push-pull clamp and release system with permanently attached wrenches eliminate the possibility of loose parts separating from the tool. This high performance machine utilizes the EscoLock wedge style blade lock system and TiN coated blades for chatter-free beveling.

| Accessory | Details |
|---|---|
| Mandrel Kit (0.5″ / 12.7 mm) – G-175 | The G-175 mandrel kit is designed to fit in the Ground gear head and will allow it to fit in tube with a 0.5″ (12.7 mm) I.D. This kit comes with a specific cutterhead that will fit the smaller 0.5″ (12.7 mm) shaft along with the draw rod assembly and G-01A ribs. Clamping range on this mandrel kit is from .5″ (12.7 mm) I.D. to .655″ (16.6 mm). |
| Air Clamp – G-270 | Air Clamp for the Ground rigidly clamps the tool to the pipe using an air clamp to pull the draw rod instead of the manual clamp wrench. With the flip of a switch, the tool can be clamped or released for high production and reduced cycle times. This accessory is only available with the pneumatic motor. |
| Right Angle Drive – G-290 | When space is not a luxury, the Ground can be fitted with the Right Angle Drive so the motors can be mounted to either side, or up/down. The Right Angle Drive is constructed out of precision machined components and is easy to assemble with all three motor options. |
| Membrane Removal – Dependent on size (see size chart) | Cutting head designed to remove the membrane between tubes on a boiler panel. Membrane heads use MRB-8 inserts, an 8 mm carbide bit, to remove material (same insert for Overlay heads). A specific base cutter head is required for mounting. |
| Overlay Removal – Dependent on size (see size chart) | Cutting head designed to remove the membrane and overlay on a boiler panel that has been coated with overlay material. Uses the same 8 mm insert as the membrane heads to remove material. A specific base head is required for mounting. Slightly smaller circumference compared to the membrane heads forces the head under hard material. |
