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 0.38mm (0.015") smaller than "ReamingShell Gauge". For more detailed information on "StandardGauge vs Reaming Shell Gauge" impregnated bits, refer tothe ITHT Product Manual.

Reaming Shells

The recommended practice, particularly in deep holes, is to alternatetwo reaming shells in each hole drilled to maintain hole diameter.Upon bit changes, the reaming shell should be checked for wear withthe bit and shell wear gauge. Failure to observe these recommendedpractices may result in either a poorly stabilized bit or an undersizedhole that will require costly reaming.

Casing Shoes

Casing Shoes

BW Standard Impregnated Casing Shoe 4102625BW Surface Set Casing Shoe 4102631

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 drill in casing for hole stabilization of surface or

underground holes when poor ground conditions are encountered(i.e. overburden, fault zones, etc.).

• Used for applications when casing is set in grout/cement forstuffing box installation at the collar of the hole.

Bit and Shell Gauge

Bit and Shell Gauge

BQ/BQTK/LTK60 Bit and Shell Wear Gauge 30002

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.

LTK60 inner and outer tubes are manufactured to

metric lengths and are best suited for use with metric rods.

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

The field proven, LTK60 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 a "B" size hole to the point where nearly "N" size core isretrieved. This makes the LTK60 core barrel system the logical choicefor conventional drilling programs.

How to Order:To order a standard core barrel:• Select a 1.5 m or 3.0 m 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/outer tube optionssections.

Ordering Information

Boart Longyear has developed an innovative and practical approachto selecting the best core barrel for your drilling application. Thisapproach incorporates a standard core barrel consisting of the headassembly, inner tube components, outer tube components, the In-The-Hole Tools Product Manual and Safety Poster. To order thestandard configuration core barrel, select a 1.5 m or 3.0 m core barrelpart number from the standard core barrel page.

There are also options available for standard product which areindicated by a “ ”. A listing of the options available appears on theinner/outer tube options sections. If you would like to substitute thestandard product for these options, select a 1.5 m or 3.0 m corebarrel part number from the standard core barrel page and specify alloptional parts and part numbers from this section.


Core barrel parts are packaged exclusively to provide the customerwith the ability to assemble the core barrel with the ideal configurationto the drilling application.

The head assembly is shipped assembled. If options are ordered forthe inner tube, they will replace the standard component.

WJ Lightweight drill rod:• Friction welded pin and box ends.• Decreased rod body wall thickness to reduce weight.• Two identification grooves on the pin end allows for easy location

of joints in the drill string.• Z-50 Thread Compound (p/n 306486, 8 kg pail) is the

recommended thread lubricant to reduce wear and the possibility ofgalling during drilling operations.

• To reduce the friction between the walls of the hole and the drillrod, apply rod grease (p/n 62796) to the surface of the drill rods.Rod grease also reduces in-hole vibration, increasing tool andequipment service life.

Drill rods MUST be pretorqued with the minimum recommendedmake-up torque to preload the box and pin prior to drilling. Drillingtorque alone will not make-up the joint. Drilling operating torqueshould never exceed make-up torque.

• Drill rod box and pin threads are protected with Z-50 ThreadCompound (p/n 306486, 8 kg pail) to avoid oxidation duringshipping and storage. Z-50 is the recommended thread lubricant toreduce wear and the possibility of galling during drilling operations.

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

Packing Features:• Casing is packaged and sold in “bundles” which offer product

protection during shipping and handling.• Protective plastic end caps cover box and pin threads sealing in

thread lubrication. For ease of identification, casing protectors arecolor-coded orange.

• 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 “BW” casing, a “bundle” contains 19 pieces.
