Hand Auger Assembly 3 1/4 in. 2 The unique cylindrical Hand Auger is ideal for augering shallow holes in fine grained soils. It requires negligible force to advance the hole because the blade diameter exceeds the bucket diameter. Little effort is required to turn the hand auger to produce a 4 inch diameter hole. Standard construction for the bucket is a heavy-guage, heat-treated, plated carbon steel. The blades are hard surfaced to resist abrasion. A stainless steel Hand Auger is available for environmental sampling needs. A special windowed bucket is available to facilitate soil removal when used in sticky clays. Extensions are 3/4 inch diameter by 3-foot long and use a threadless design to avoid the need for wrenches. Quick connect pins are used to join the tee handle, extensions and bucket. A Hand Auger assembly set consists of one auger head, one tee handle and one extension. Purchase additional extensions for desired depth capacity. *Other sizes available on request.

Samplers 5

Thin Wall (Shelby) Tube 5 The Thin Wall or Shelby Tube Sampler is designed to take undisturbed samples in cohesive type clays and soils. The sampler consists of a head assembly, ball check and cap screws for securing the sampler tube. The sampler tube consists of a head assembly, ball check and cap screws for securing the sampler tube. The sampler is pressed and retracted by hydraulic force into the undisturbed clay or soils. The tube is then removed from the sampler head and the sample is retained in the tube and transported to the laboratory. The thin wall sample tubes are made available in either steel, galvanized steel or brass in varying lengths. The procedure for obtaining undisturbed samples is outlined under ASTM Standard Procedures. NOTE: If your environmental needs require, the thin wall sample tubes are available in stainless steel.

The Lynac Sampler is a heavy duty split tube sampler that is widely used in the geotechnical/environmental drilling industry. This sampler is adapted for severe service under hard driving conditions. The sampling shoe is heat treated and coarse threads in the sampler head speed disassembly and assembly. The head of the assembly comes with a ball check feature that helps prevent losing a sample by washing out during withdrawal from a test boring. The heat treated shoe is recessed to allow the use of a basket retainer or trap valve. Liners for the split tubes are also available for specific sampling needs. Lynac Samplers are available in either an 18 or 24 length and the split tubes can be heat treated for the 2 OD size. 5 NOTE: This heavy-duty Lynac Sampler is recommended for Standard Penetration Tests for geotechnical drilling.

5 This is a general, all-purpose slit-tube sampler that can be used in both the geotechnical and environmental drilling industry. This sampler has a solid sleeve or extension that is threaded and connects the split tubes with the head assembly. The purpose of the extension is for retaining any loose soil which may have collected at the bottom of the test boring. The samplers are available in 12 in., 18 in., and 24 in. lengths. The sampling shoe is recessed to allow the use of a basket retainer or trap valve.

Wireline Coring System NQ Overshot Compact Overshot NQ Features: For surface or downhole applications with NQ/NQ3/NQ2 core barrels. Stonger lifting dogs and lifting dog compression spring. Threaded connection between jar staff and overshot head. High strength alloy steel jar staff with increased diameter and fail safe stop. Eye bolt machined with radius to eliminate need for thimble. Dry Hole Lowering: In dry holes, the overshot assembly is used to lower the inner tube assembly. The locking sleeve will release the inner tube assembly upon contact with the water table or when the landing shoulder makes contact with the landing ring. The taper on the spearhead point forces the top end of the lifting dogs inward, allowing the locking sleeve to drop down and lock the lifting dogs open. The set screw (#16) can be used when dry hole lowering to prevent the locking sleeve from cable jumping.! WARNING The inner tube assembly can be released prematurely if it encounters resistance inside the rod string that resembles contact with the water table or landing shoulder, i.e. bulged rod joints. Releasing the Overshot Assembly: If the inner tube assembly becomes stuck in the outer tube, the locking sleeve is used to release the overshot. The locking sleeve is guided onto the wireline cable through the guide slot and dropped to the overshot/inner tube assembly. The locking sleeve drops over the lifting dogs and locks them open to allow the overshot to be pulled from the hole. NOTE: Refer to the ITHT Product Manual for additional operating information.

Casing Advancer Part No. Type Casing Advancer Assemblies 59000 NW 59075 HW 59084 HQ 3000863 HWT 59398 PW NOTE: Other sizes available on request. 7 For the first time a Casing Advancer assembly which allows you simple removal and replacement of the advancer with ensured positive relocation 7.19 Wireline casing advancers provide an efficient one step method of drilling through overburden and casing off to bedrock. Until now removing and replacing the advancer inner assembly for soil sampling, coring or bit changing was an unreliable and difficult procedure. How could you be sure that the advancer assembly would relocate correctly in the driving sleeve? Self-regulating Stop Latches Boart Longyear has developed simple self-regulating stop latches (patent pending) which reliably and accurately relocate the inner assembly in the driver no matter what the condition of the overburden. Removal and replacement of the Boart Longyear Casing Advancer is rapid, easy and positive. No special presetting or positioning of the latch mechanism is required prior to insertion; just lower it through its loading sleeve into the casing. Self-regulating Stop Latches locate the inner assembly accurately in the driver sleeve. Spring-loaded Drive Latches engage with driving keys and positively latch into the key recess until the weight of the inner assembly is taken by an overshot. Coring and Soil Sampling as required Overburden coring and soil sampling can be carried out with confidencs as often as required. The Boart Longyear Casing Advancer inner assembly returns quickly and positively to the keyed driving recess in the sleeve. Changing bits to optimize penetration rates is also now possible. Positive Latching, Positive Reaming For maximum drilling efficiency the postion of the drilling bit relative to the casing shoe is important. Correct position prolongs the life of the casing shoe by ensuring that it only does the job it was designed for; sizing the drilled hole for the casing. Boart Longyear s positive latching, case hardened drive latches securely locate the inner assembly and bit at a predetermined distance in front of the shoe. This distance is adjustable by the driller to suit the nature of the overburden and the type of bit being used.

Diamond Products Reaming Shells Reaming Shells: Based on Customer input and product research we have developed a new line of reaming shells which are available in both our Standard Straight Pad and our Spiral Pad products. The new reaming shells offer the following improvements: 1. Matrix: The new matrix improves wear resistance and diamond retention. The new reaming shell is tougher: it can withstand more shock and vibration stresses because the increased ductility of the matrix forms a much stronger bond with the steel blank. 2. Pad Setting pattern: The diamond and carbide reinforcement setting pattern has been modified to give extra protection to areas that are more susceptible to premature wear. 3. Design: The entire reamer, pad and waterway matrix has been extended to the shoulder. Because the reamer pads start right at the bit joint, the wear resistance of the reamer s leading edge is improved, which results in longer life. Particularly recommended in abrasive conditions. 8 Boart Longyear ECONO shells are recommended for lighter applications where there is no extensive diamond core drilling but where intermittent or spot coring is the task at hand. ECONO shells are preferred in geotechnical and other shallow hole explorations. The longer pads have more diamonds and carbide reinforcement which offers longer life.

Monitor Well Construction Materials CircumSlot Boart Longyear Circumslot is a single piece extrusion well screen that is internally ribbed to permit circumferential slotting. This special slotting provides maximum strength and uniform material composition. This higher open area means maximum ability for fluids to enter the well casing. The uniform distribution of openings enables total formation development and allows stratified fluids to enter the well. Circumslot is an excellent choice for low yielding formations to enhance sample retrieval when monitor wells recover slowly. It provideshigher, less restrictive flow into product recovery remeiation wells where maximum fluid retrieval is desired. Flush threaded joints mate directly with TriLoc pipe or 2 TPI pipe; integral threads won t pull off. Circumslot screen and all Boart Longyear PVC pipe meets ASTM F 480 standard. Fully Circumferential Slots Allows complete access to well formation. Uniform distribution of openings allows complete well development and more accurate sampling. Lower head flow into the screen. Increased Open Area Full 360 slot provides same open area as wire-wound and more than double that of conventional slotted screen. Allows complete non-segregated flow. Single Piece Extrusion An integral TriLoc flush-thread joint means no thread pull-off. Seamless construction and uniform material composition mean greater strength. Available in TriLoc or 2 TPI thread design. Cost Savings CircumSlot can provide a more cost effective well construction material as more open area means faster well development and reduced purging time. Open area is comparable to wire wrapped screen, at a greatly reduced cost. Overall cost of your monitoring or recovery program is reduced. Increased Inside Diameter The 4 in. and 6 in. CircumSlot are custom extruded to provide a true 4 in. and 6 in. ID, allowing easier equipment installation. 2 in. CircumSlot has a 1.75 in. ID. Part Circumslot Description TCS-151 PVC, 2 in. x 5 ft.
