Pengo’s patented BoRH (Bolt on Rock Head) provides the ultimate solution for all your drilling applications. Designed to convert a standard Aggressor® Dirt Auger into a rock auger, the BORH® eliminates the need for an additional and dedicated Rock Auger. The BORH® kit contains our boring head, pilot bit, wear caps, bullet-style carbide teeth and all hardware needed to complete the installation. Featuring innovative wear caps and enlarged shoulders on the teeth for increased wear, the BoRH® system provides the ultimate solution across a wide variety of soil conditions.
Augers Compatible with BoRH Attachments
The BoRH® is compatible with Aggressor® augers made with a one- piece cast auger head. The auger head acts as the tooth and pilot mounting platform. Below are things to look for when determining if your auger is compatible with the BoRH® system.
• The height of the new pilot adapter (Dimension A) is 2-1/2″. If this dimension is 1-1/2″, then the auger head was fabricated and may not work well with the BoRH® attachment.
• If there is a weld bead in the areas pointed out with B, then the auger head was fabricated and may not work well with the BoRH® attachment.
• The compatible 1 piece cast auger head will have cast raised lettering in Area C. The lettering will have the auger diameter followed by a “-AR”. Directly below that will be a part number that ranges from 137692 – 137697 depending on size. If your auger does not have those markings, then the Auger Head was fabricated and may not work well with the BoRH® attachment.
NOTE: If the auger has excessive wear, the lettering may no longer be present. In those cases, refer to A & B to determine compatibility.
Instructions To Convert Pengo Standard Aggressor® Auger Into a Rock Auger
Step 1 – Remove Dirt Components
Remove the Pengo® TriFlow® Pilot Bit & 40/50 Teeth as shown by removing 1/2″ Nuts & Bolts with 3/4″ wrench or socket.
Step 2 – Install Rock Head
Insert Cast Rock Head into Auger Head and secure into place with 1/2″ Nut & Bolt through center of auger as shown below. Make sure rock head is orientated so that the holes in the rock head line up with the holes in the Auger head
Step 3 – Install Wear Caps
Place Wear Caps onto Dirt/Rock Head as shown below. Make sure that the holes in the wear caps line up with the holes in the auger and rock head. Place 1/2″ x 1-1/4″ Hex Bolts into wear caps so that the hex head seats in the hex recesses of caps. Tighten 1/2″ nuts onto bolts placed on underside of rock head with 3/4″ thin-walled socket.
