Ditch Witch®, a Charles Machine Works Company, has released a new line of HD (heavy duty) backreamers to help underground construction operators improve productivity and tool durability on horizontal directional drilling (HDD) job sites. New to all model designs, the HD backreamers are now equipped with standard API threads to fit any industry drill under 100,000 lbs.
The new models include the Beavertail HD, Warthog™ HD, Kodiak™ HD and Compact Fluted HD backreamers.
“Reamers are the frontline soldiers to tackle expanding requirements of extreme soil conditions, which is why we pride ourselves on providing long-lasting and ruggedly built reamers,” said Jaime Wines, director of parts sales and marketing, the Ditch Witch organization. “The heavy-duty design of our newest models enhances tool life and durability, providing drill operators with confidence to bore through the toughest soil conditions.”
Beavertail HD Backreamers: For improved fluid flow, the Beavertail HD backreamers are equipped with replaceable, hardened steel Allen head nozzles. A flow-through shaft and rugged cutting design give this backreamer efficient fluid mixing capability, requiring far less horsepower for rotation in a variety of soil conditions. These also use a box design on the trailing side of the reamer for step reaming, direct connect swivels or threaded tabs to fit each contractor’s needs using 3 1/4-inch shafts and above. Step reaming reduces the number of passes needed to attain an accurate hole size, saving time and money on the job.
The Beavertail HD backreamers are available in two versions, accommodating small and large drill rigs. The small version includes a 2 3/4-inch shaft available in eight diameter sizes from 6 to 20 inches, and a pull tab integrated directly in the shaft. For larger equipment, reamers are available with 3 1/4-inch, 4 1/4-inch and 4 3/4-inch shafts ranging in diameter up to 40 inches, including the box design.
Warthog HD Backreamers: Designed to require less torque and reduce drag when back reaming, the Warthog HD model improves production and flow efficiency around the cutters and reamer body. Similar to the Beavertail design, the Warthog HD backreamers also feature hardened steel Allen head nozzles and utilize the same box design for flexibility to set up the ideal configuration for specific job needs using 3 1/4-inch shafts and above.
For compact drill rigs, the Warthog HD backreamers have a 2 3/4-inch shaft available in diameters from 10 to 36 inches. This size includes a pull tab integrated into the shaft, providing a common industry connection point for swivels and saving in reamer weight and length. For larger equipment, the Warthog HD backreamers are available with 3 1/4-inch, 4 1/4-inch and 4 3/4-inch shafts ranging in diameters from 10 to 36 inches, including the box design.
Kodiak HD Backreamers: To reduce friction and the possibility of jams while drilling, the Kodiak HD backreamer enables cuttings and fluid to flow over the product and out the bore hole by providing optional drilling fluid from the rear of the tool.
The Kodiak HD backreamers are available in 2 3/4-inch, 3 1/4- inch, 4 1/4-inch and 4 3/4-inch shaft sizes ranging in diameter from 8 to 36 inches. All sizes feature an integrated swivel with a clevis or tab option, which places the product closer to the reamer and reduces the chance of binding. A new clevis design eliminates the need for multiple connections between the clevis and product.
Compact Fluted HD Backreamers: Similar to the Kodiak HD design, the Compact Fluted HD backreamer reduces friction and the possibility of jamming by forcing fluid out the swivel plate. The improved heavy-duty casting design provides smooth pushback and maximum durability. Integrated swivel with a clevis or tab option reduce the possibility of binding by placing the produce closer to the reamer and eliminate the need for multiple connections between the drill and reamer.
Ranging in diameter from 4 1/2 to 26 inches, the Compact Fluted HD backreamers are available in 2 3/4-in, 3 1/4-inch, 4 1/4-inch and 4 3/4-inch shaft sizes.
The new line of HD backreamers will be on display in Ditch Witch Booths K155 and K270 at the 2015 ICUEE event taking place Sep. 29 to Oct. 1 in Louisville, Kentucky.
