Piercing Tools: Equipment Spotlight
Piercing tools from TT Technologies, Footage Tools, HammerHead Trenchless, Hudco Mfg., Allied Construction Products.
Grundomat can perform accurate horizontal bores from 50 to 150 feet in length. The Grundomat can be used in all displaceable soils: sand, loam and even gravel and is easily configured to pull in a wide variety of new pipe materials. The reciprocating stepped-cone chisel head action of the Grundomat tool is unique because it hammers away at solid obstacles. This two-stroke action means that the piston's impact is concentrated on the reciprocating tool head for optimum boring performance. In addition, the tool has minimal impact on the environment as it utilizes natural biodegradable lubricants. The Grundomat is ideal for electrical contractors and FTTH installations. 800.533.2078, tttechnologies.com
All Big Shots (pneumatic piercing tools) are CNC machined to exact dimensional tolerances from a solid billet of nickel chromoly steel and fully heat treated for superior strength and wearability. The pistons are designed to withstand high impact conditions, are wear resistant and treated with an anti-corrosive phosphate coating. Big Shots are available in 2-, 2.5-, 3- and 4-inch diameters. Other features include an easily replaceable cartridge style shock absorber and a flexible air tube assembly to minimize internal deflection. 888.737.3668, footagetools.com
The Catamount line of piercing tools from HammerHead offers the industry a reciprocating head tool that is easy to start, regardless of air pressure level, and is effective in both hard and soft soil conditions. The Catamount tool line is currently available in 2.5-, 3- and 4.375-inch diameter tools. The Catamount head is driven by air that resets the head, eliminating the need for mechanical springs and allows for a faster and easier start by eliminating the need to overcome recoil. The patented Power Port quarter-turn reverse feature pneumatically locks the tool into forward or reverse gear, preventing accidental direction change during the bore. The valve whip is designed to be flexible, preventing tool binding if a bore collapse occurs. A one-piece body made of heat-treated alloy steel allows HammerHead to use a much heavier striker, increasing overall impact force. The one-piece body also provides better durability and tool life. 800.331.6653, hammerheadtrenchlesss.com
