The hole is made when the drill rig lifts the earth up through the borehole by the blade of the screw. Crews are often working in some of the hardest rock conditions around - limestone, shale, and shelving. Because of regulations, they can’t use dynamite to break up the ground so they use a com- bination of jackhammers and air hammers to start the holes, and then use digger derricks and pressure diggers with auger tools to do the rest. It was taking a lot of time for crews to complete new holes, and the toll on the equipment was notice- able. “Drilling contractors need to be able to tackle any ground condition with one machine,” said Putnam, “As productivity directly correlates to profits, using the right tool maximizes both.” Many manufacturers offer rock augers designed in a similar configuration to their earth augers, except the rock augers are fitted with different teeth. For faster cycle times in and out of the hole in extreme ground conditions, specialized auger tool- ing, like the newTerex ® Texoma spiral bul- let tooth auger, is available to achieve higher production drilling rates. The cut pattern and tooth attack angle on the Terex auger combine to make the bullet teeth act like fingers penetrating through and lifting up fractured or broken material. “With its spiral-shape design and unique tooth pattern that distributes the cutting action evenly,” stated Putnam, “this auger equalizes the work done by each tooth on the cutting tool, increasing pro- duction rates and reducing tooth wear.” According to Putnam, with a standard auger tool, one hole could take crews up to eight hours to drill. With the Terex Texoma auger, the same hole may only take them30minutes to complete. “Having an auger tool specifically designed for these conditions definitely makes a dif- ference,” concluded Putnam. “And, Terex offers a variety of flighting thickness and pitch options for this auger, as well as custom specifications upon request to meet every customer’s particular drilling needs and conditions.” )' ) % ) ' # *# $ ' : &4)1*4 *18*4 : : &4)1*4 *18*4 : : &4)1*4 *18*4 : : &4)1*4 *18*4 % ( ) ' ) '%# : &4)1*4 *18*4 : : &4)1*4 *18*4 : : &4)1*4 *18*4 : &4)1*4 *18*4 : &4)1*4 *18*4 ' $ + *#&( $ )% ! &4)1*4 *18*4 : # #4-3/*: ! ! &4)1*4 *18*4 : # #4-3/*: ! ! &4)1*4 *18*4 : 24 : 73/*: ! ! &4)1*4 *18*4 : 73/*: ! ! &4)1*4 *18*4 : -4 4-8* 73/*: ! ! &4)1*4 *18*4 : 73/*: ! ! &4)1*4 *18*4 : 73/*: ! ! &4)1*4 *18*4 : 73/*: ! ! &4)1*4 *18*4 : 73/*: ! ! &4)1*4 *18*4 : # #4-3/*:>> ! ! &4)1*4 *18*4 : #4-3/*:>> > ! ! ;)4&7/-( 4276 703 ? ;)4&7/-( 4276 703 ? ;)4&7/-( 4276 703 ?
