Bit

Boart Longyear introduces metal coated diamond impregnated bits -the latest in industrial diamond technology.• Significantly outperforms the successful Series range in both drilling

speed and bit life.• Protects the diamond from oxidation and surface degradation

during manufacturing.• Inhibits the premature "pull-out" of the diamond.• Increases the number of cutting edges exposed to the rock.• Available in multiple standard configurations and selected on the

basis of relative rock hardness and ground conditions.

Impregnated Bits

* Available on special request.

NOTE: Refer to the Tech Data section for technical specifications andthe ITHT Product Manual or the Diamond Products FieldManual for additional operating information.

Standard: Designed to handle a wide variety of formations.

Abrasive: Recommended for broken "abrasive" drilling condtions. Forharder rock with broken conditions use a higher number bit tomaintain good drilling speeds.

Competent: Free cutting design for fast penetration in very hard"competent" rock or for use on lower powered rigs and geotechnicalapplications.

Express Geometry: Bits are supplied with additional intermediatewaterways which provide increased flushing. The reduced bit facearea allows for higher penetration rates with less bit weight required.Recommended when polishing occurs with standard geometry.

NOTE: "Standard Gauge" bits are defined as having a set outsidediameter which is 0.25mm (0.010") smaller than "ReamingShell Gauge". For more detailed information on "StandardGauge vs Reaming Shell Gauge" impregnated bits, refer tothe ITHT Product Manual.

BOART LONGYEAR

Reaming Shells

The recommended practice is to alternate two reaming shells in eachhole drilled to maintain hole diameter. Upon bit changes, the reamingshell should be checked for wear with the bit and shell wear gauge.Failure to observe these recommended practices will result in either apoorly stabilized bit or an undersized hole that will require costlyreaming.

Casing Shoes

Casing Shoes

AW V-Ring 508430

Casing ShoeThe inside diameter of the casing shoe is not set with diamonds andis flush with the inside diameter of the casing, permitting free passageof the core barrel past the casing shoe.

Applications:• The casing shoe is threaded to the end of the casing string for

penetration through overburden.• Assists in seating the casing into the bedrock, providing a tight

seal for the drilling fluids to flow through to the surface.• Used to ream the casing downward when advancing a casing

string in an existing hole with the rod string still in place.

Applications:• Used when deep or difficult overburden is encountered.• When reaming operations are completed, the casing string is

removed from the hole and a casing shoe is substituted for acasing bit before normal drilling operations recommence.

Bit and Shell Gauge

Bit and Shell Gauge

AQTK/LTK48 Bit and Shell Wear Gauge 30003

Bit and Shell Wear GaugeAs good practice, the diameter of impregnated bits and reamingshells should be measured. This will ensure that the hole size ismaintained. Impregnated bits typically maintain their gauge untiltotally consumed.All holes should be collared with a full gauge reaming shell. Ondeeper holes, two or more shells should be alternated in the hole tomaintain the hole size. Reaming shells should be gauged frequentlythroughout drilling operations to avoid costly reaming of undersizedholes.

Corrugated or Flat FaceFor impregnated bits with a kerf width over 7.5mm (0.30”) thestandard crown profile is corrugated, and flat for kerf widths equal toor under 7.5mm (0.30”).

Non-Coring BitsTheir design provides reinforcement of the center of the bit to preventexcessive wear of this critical area. Various center designs, includingpencil core and crowsfoot types, are available to suit your particularneeds. Water courses are carefully engineered to provide fast andcomplete evacuation of the cuttings produced by this type of tool,thereby increasing the penetration rates in all types of formations andincreasing bit life. Other non-coring bits are available for hydroelectricgrouting applications including non-coring TSD bits.

The field proven, LTK48 Thin Kerf Conventional Coring System offersa cost effective, high production alternative to conventional wider kerfcore barrels. The Thin Kerf core barrel was designed for optimumproduction and core recovery in medium to extra hard formations.Small, lightweight circulation pumps can provide the low drilling fluidflow rates required. The use of water or polymer based drilling fluids isdesirable (clay based drilling muds are not recommended due to thesmall annulus between the inner and outer tubes). The low bit weightnecessary to run thin wall impregnated bits reduces wear and tear onthe drill and rods, and improves core recovery in highly fracturedground.

By minimizing on bit kerf, Boart Longyear has effectively increasedcore size in an "A" size hole to the point where nearly "B" size core isretrieved. This makes the LTK48 core barrel system the logical choicefor conventional drilling programs.

How to Order:To order a standard core barrel:• Select a 1.5 m/5 ft or 3.0 m/10 ft core barrel part number.

Options:There are alternatives to the standard core barrel which are indicatedby a “ ”. To view these options refer to the inner tube options section.

Follow these instructions carefully:

Inner Tube Components1) Apply rod grease (p/n 62796) to the inside of the core lifter case

and to the outside of the core lifter.2) Insert the core lifter into the core lifter case from the threaded end.3) Apply Z-50 thread compound (p/n 306486) to the threaded ends of

the head assembly, core lifter case and inner tube.4) Thread the head assembly to one end of the inner tube and the

core lifter case to the other. Use an inner tube wrench to ensurethe joints are snug.

Outer Tube Components1) If the core barrel is intended for storage, thread the head

assembly, complete with the inner tube, to the outer tube andattach the thread protector. If the core barrel is intended forimmediate use, install a reaming shell and bit instead of the threadprotector.

2) Tighten all joints with an outer tube wrench to ensure they aresnug.

NOTE: For complete operating instructions, refer to the ITHT ProductManual that is shipped with every core barrel.Clearly post the Safety Poster in your work area.

• Heavy duty galvanized hexagon bundle end caps (p/n 41072)protect the casing ends.

• Casing box and pin threads are protected with Z-50 ThreadCompound (p/n 306486) to avoid oxidation during shipping andstorage. Z-50 is the recommended thread lubricant to reduce wearand the possibility of galling during drilling operations.

• Casing is coated with Krown KL73 rust inhibitor (p/n 3543544) toreduce product oxidation during shipping. When storing casing forlong periods of time, it is recommended to reapply to the productsurface for maximum protection.

For “AW” casing, a “bundle” contains 19 pieces.
