Tube and Pipe Beveling Tool.
The Ground MILLHOG.

The Ground MILLHOG is a right angle, I.D. clamping beveling machine that is only 1.5in (38.1mm) 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.

MANDREL KIT 0.5"

Mandrel Kit (0.5"/12.7mm) part #: G-175

The G-175 mandrel kit is designed to fit in the Groundhog gear head and will allow it to fit in tube with a 0.5” (12.7mm) ID. This kit comes with a specific cutter head that will fit the smaller 0.5" (12.7mm) shaft along with the draw rod assembly and G-01A ribs. Clamping range on this mandrel kit is from .5" (12.7mm) I.D. to .655" (16.6mm).

Includes

Air Clamp

Air Clamp part #: 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.

Includes

RA Drive

Right Angle Drive part #: G-290

When space is not a luxury, the Groundhog can be fitted with the Right Angle Drive so that the motors can be mounted to either side, or up/down. Kike all of our tools, the Right Angle Drive, is constructed out of precision machined components and is easy to assemble with all three motor options.

Includes

Membrane

Membrane Removal part #: 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 8mm carbide bit, to remove material (same insert for Overlay heads). A specific base cutter head is required for mounting.

Includes

Size Chart

Overlay

Overlay Removal part #: 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 8mm 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.
