Electric, cable, gas, water and irrigation projects can be tackled with ease using the Vermeer by McLaughlin Hole Hammer piercing tools. The new VPT 250 Short model allows for work in tight areas, such as congested urban areas and metropolitans. The VPT 250 Short is a positive-turn reverse design with a shorter body, so contractors can dig a more concise entry and exit pit for a more efficient job site and have less impact on surrounding neighborhoods.
The overall length of this new 2.5-inch-diameter piercing tool is only 35 inches, compared to the standard 2.5-inch tool, which is 59 inches. Though shorter in length, it is long on power with 720 blows per minute versus 385 blows per minute with the standard length tool. This version of the positive turn tool is popular in the Northeast U.S. and Europe, and where shorter bores in medium soils are encountered.
The positive-turn reverse design lineup has minimal moving parts and is available in 2-, 2.5-, 3- and 4-inch (5-, 6.4-, 7.6 and 10.1-cm) sizes. An innovative tailbolt design provides for excellent rear anvil clamping force and only requires a maximum of 35 foot-pounds of torque. The replaceable head design is made from CNC machined heat-treated alloy to protect the tool body and can be replaced to extend the tool body life cycle. Additionally, the design runs one of the heaviest striker-to-body weight ratios in the industry, boasting maximum power and performance.
Vermeer by McLaughlin Hole Hammer line also features air-on quarter turn reverse design available in 1.8-, 2-, 2.5-, 3 and 3.3-inch (4.5-, 5-, 6.4-, 7.6, 8.4-cm) tools with both a replaceable head and moving head designs. Increased production and accuracy can be found with the moving head design, which provides full striking force of the piston to the head of the tool, pulverizing stones in the surrounding soil and is reset after each blow with the mechanical spring reset. The residual energy created is used to help the tool body travel through the compacted bore path. This results in both increased production and improved accuracy in tough soil conditions.
The Hole Hammer piercing tool line is available through the Vermeer dealer network.
