Portable Rock Core Drills
& Core Orienting Fixtures

 


Pomeroy EZ Core Drill
Model D261-C

The Pomeroy Model D261-C gasoline powered drill is designed for paleomagnetic, geochemical and other sampling. This drill is lightweight, reliable and features a unique bit fastening system that holds bare-shank bits (without collets) straight and true without the use of tools. 

The D261-C replaces Pomeroy's previous Model D026-C.  It utilizes a new, powerful 50 cc motor and weighs just 13 lbs.  The engine is the latest in 2-stroke technology with omni-directional fuel pick-up for running at any angle and microprocessor-controlled ignition system that cuts exhaust emissions up to 50% from previous models.


The front end drilling adapter is the same as that used on the D026-C.  It features heavy duty sealed bearings and the exclusive easy operating bit fastener. The fastener will accommodate bits with a tube diameter from 1.080" to 1.125". The adapter is anodized high-tensile aluminum alloy and mounts, without tools, to an alloy plate that is screwed to the motor. A quick- release hose fitting and needle valve are mounted on the bearing case for rapid attachment and control of the water cooling line.

 

 

Additional Components Include:

Model M-12 3-gallon manually pressurized water pump can. It includes an 8 ft. hose and one 10 ft. extension fitted with quick-release connectors.

Pomeroy BSS-1E Drill Bit

Heavy duty diamond drill bit with stainless steel shanks for use with older D-2801 and current Model D026-C Pomeroy core drills. They are 1" I.D., 1 1/8" O.D. and 8" long and cut holes which fit most paleomagnetic orienting devices, including those sold by ASC.  Bit has two small notches at 180 deg., cut about 1/3 of the depth into the diamond crown.

The BSS-1E bit is equivalent to and replaces the Pomeroy BSS-1 and BSS-1P bits, which have been discontinued.

CORE ORIENTING FIXTURES

Pomeroy Orienting Fixture

This precision orienting fixture is used to measure the azimuth and dip of in-place cores drilled with 1 1/8" core drill bits (1" core ID). It features an anodized aluminum tube and orienting platform which is adjustable using a tripod-style clamping handle. A small cylindrical wedge is included, which can be fitted onto the tube (as shown near the bottom of the photo) and used to lock the orienter in place over the in-place core while measurements are being made.  The platform is machined to accommodate a clear plastic sun compass (included) or, with sun compass removed, a Brunton pocket transit for magnetic azimuth measurements. (Orienter will accommodate only the aluminum-case Brunton models.  The plastic/composit Compro Brunton models cannot be used.)  Once the platform is leveled using a Brunton compass, sun and/or magnetic azimuths can be measured, and core dip angle can be measured using the fixture's vertically mounted protractor.

Model OR-2 Pomeroy Orienting Fixture..............$  778.00

 

ASC Orienting Fixture

This simple, rugged fixture is designed for rapid orientation of in-place 1" (nominal) cores using a Brunton pocket transit. The copper tube has a slot for marking the top of the in-place core. The brass orienting platform is machined to accept a Brunton compass for making azimuth measurements. Dip measurements are made using the Brunton placed on the portion of the tube extending out from the outcrop.  (Orienter will accommodate only the aluminum-case Brunton models.  The plastic/composit Compro Brunton models cannot be used.)

Electric Core Drill Model DE-T3

The Pomeroy Electric Core Drill makes drilling of small diameter cores extremely fast and easy in locations where the use of a gasoline-powered drill is not possible.  Because battery life is limited, however, this drill is meant for special circumstances and is not a replacement for a gasoline drill.

The DE-T3 is based on a Makita high-powered 18 volt Lithium cordless drill.  The miniature water swivel, which enables drilling with diamond core bits, is an integral part of the drill and provides the best drilling solution available. It ships complete with drill, 2 Lithium-Ion batteries, charger, wrenches and carrying case. The range of diameters for drill bits is 3/8" ID to 1" ID. 

Drilling requires water coolant, which can be provided by the available M-12 water pump can.

Battery charger for DE-T3 drill has a US plug and operates with 110VAC only.  For use in Europe/Asia a small 500 watt, 220V/110V step down transformer can be supplied at extra cost.  Please contact ASC Scientific for additional information.

and
FIRE, SEARCH & RESCUE and SPECIALIZED OPERATIONS

Features:

  • Lightweight, Reliable & Easy to Operate
  • Suitable for Drill Bits up to 4" OD
  • Powerful 48cc 2-cycle Motor
  • High-Torque Gear-Reduced Drive
  • Omin-Directional Fuel Pick-up for running at any angle


BS-4PRO Bit

Pomeroy Model D026-GT10 gasoline powered drill for geological sampling, Fire Departments, Search & Rescue and other specialized operations is lightweight, reliable and easy to operate.  The D026-GT10 has a powerful 48 cc motor and weighs approximately 15 lb. The motor is a popular American-made model that has ball bearing crankshaft, centrifugal clutch, easy-starting capacitive discharge ignition, and omni-directional fuel pick-up for running at any angle.

The integral high-torque gear reduced drive makes this drill suitable for fast drilling with diamond bits up to 4" outer diameter.  Drill bit connection to the drill drive shaft is 1 1/4"-7 thread

A three gallon (M-12) manually pressurized water pump can is available. It includes an 8 ft. hose and one 10 ft. extension fitted with quick-release connectors.

We also offer a light-weight aluminum 1-3/4" wrench, which is recommended to hold the drive shaft steady for easy removal of drill bits. 

The bits have diamond crowns with 1/8" wide kerf.   Internal diameters of bits are therefore 1/4" less than listed O.D.'s.
