Coug Ar S Tabiliza Tion COUGAR STABILIZATION COUGAR STABILIZATION PRODUCT TECHNICAL SHEET OVERVIEW Cougar Stabilization COUGAR STABILZATION COUGAR DESIGNED AND Built to PERFORM Cougar Drilling Solutions’ stabilizers, reamers and keyseat wipers are consistently constructed to exacting standards. To start, we use only 4145H heat-treated, stress-relieved steel, every bar of which is tested by independent metallurgical laboratories to verify its quality. We then dedicate a single piece of steel for each stabilizer, reamer and keyseat wiper that we mill. All connections are machined to API specification, bore backed, stress-relieved and phosphated. DESIGNED FOR BETTER PERFORMANCE INCREASED PENETRATION Cougar DS’ stabilizers permit increased weight on the bit for increased penetration, but without the deviation problems associated with high weight on bit. FEWER PROBLEMS Increased weight on the bit means you’ll have fewer buckling and bending problems. Drill collar friction and torsional fatigue is also reduced. STRAIGHTER HOLE Our Taper Blade reamers and keyseat wipers prevent the formation of doglegs and keyseats. IMPROVED FLUID PASSAGE Clearance between the hole bore and drill collar is critical. Cougar DS ensures maximum circulation by milling the fluid passageways between the stabilizer blades to neck size, which retains a safe margin of strength and excellent fluid passage. The result is superior hydraulics that pays off in maximum bit penetration rates. PLASMA TRANSFER ARC Cougar DS consistently uses Plasma Transfer Arc (PTA), to rebuild Cougar DS stabilizers to the correct gauge. PTA consists of a nickel-based hardfacing powder containing tungsten carbide. This alloy is specifically designed to stand up against severe abrasion or moderate combined corrosion and abrasion. PTA is abrasion and friction resistant because of tungsten carbide particles evenly distributed throughout the entire matrix of the stabilizer blade. This production of tiny grains of tungsten carbide, melted by a revolutionary process, reaches a hardness of 3000-4000 on the Vickers hardness scale. Cougar DS uses unique welding methods, applying tungsten carbide directly to the base metal of the stabilizer instead of laying it on the carbide. This allows increased bonding directly to the tool’s base metal. Tungsten carbide confers to these particles with an astonishing degree of impact strength and abrasion resistance allowing the tool more running time with less wear and consistent performance. PRODUCT TECHNICAL SHEET OVERVIEW Cougar Stabilization COUGAR STABILZATION COUGAR PRODUCT TECHNICAL SHEET OPEration Cougar Stabilization COUGAR STABILZATION COUGAR REAMER PERFORMANCE Cougar Drilling Solutions’ roller reamers are manufactured to give long service even under the most severe reaming conditions. Cutters, bearing blocks and cutter pins are made from molybdenum alloy steel, carburized and quenched to 58-62 Rockwell C. Cutter pins can be rotated 180 degrees for prolonged use. FastER REDRESS Changing cutters is simple: drive out one spring-pin and the cutter pin, and replace them. A punch, drive bar and hammer are the only tools you’ll need. GREatER VErsatilitY Cougar DS roller reamers are available in 3-point or 6-point configurations for bottom hole or string applications. The 6-point bodies, for use in severely crooked holes, will minimize doglegs and optimize hole configuration. TOP-OF-THE-LINE STABILIZER COATINGS Even the most abrasive formations won’t affect the performance of Cougar DS wear and cutting products. Cougar DS stabilizers are coated with state-of-the-art hardsurfacing. We use melted carbide grains to form a polycrystalline matrix that holds ingots of pure tungsten carbide. Nickel-chrome is added to the matrix to increase shock and impact resistance. This hardsurfacing process produces a hard-wear surface (4000 hardness on the Vickers scale) with a very low expansion coefficient and good elongation capacity. This means you have a tool with incredibly solid hardsurfacing, but without tool distortion and cracking. StabilizERS AND REAMERS STURDY KEYSEAT WIPERS For tricky situations where you think you could stick the string in a keyseat, Cougar DS Keyseat Wipers are the tool of choice. A double clutch design means you can wipe the hole clean going in or coming out. And if you do get stuck, the sliding sleeve lets you keep rotating. Additionally, the body of the tool is one-piece construction, so no welded joints can give way while jarring on the pipe. The sleeve carbide coating is finished in the same aggressive style as the taper blade reamers, so it reams and cleans holes fast. ROCK-SOLID REAMERS Cougar DS reamers are manufactured to give long service even under the most severe reaming conditions. Milled, one-piece bodies in 3-point or 6-point configurations provide enormous strength while allowing maximum fluid flow around the reamer in both bottom- hole and string applications. A variety of cutters are available for every formation type, be it chert, sandstone or shale. PRODUCT TECHNICAL SHEET OPEration Cougar Stabilization COUGAR STABILZATION COUGAR AGGRESSIVE TAPER BLADE REAMERS Razor sharp carbide cutters, Cougar Drilling Solutions taper blade reamers use chunky, sharp, aggressive pieces of carbide to carve up doglegs and tight spots. The huge exposed surface of sharp shards of tungsten carbide is held together in a nickel matrix that is designed to be softer than our stabilizer matrix. The means that as the sharp edges of the carbide wear down in the hole so does the matrix, exposing more sharp carbide underneath. The more cutting the taper blade reamer does, the sharper the blades become. REAMER/STABILIZER COMBINATION TOOLS For tough drilling where maintaining hole size and controlling deviation is a problem, Cougar DS offers one-piece reamer/stabilizer combination tools. Available in sizes from 6” to 17 ½”, these tools are made from a single billet of steel and are designed for use in the toughest and more faulted formation. One-piece construction means one less connection in the drillstring and optimum control over hole diameter. LONGWEARING STABILIZERS Grinding it out downhole, Cougar DS’ integral blade stabilizers are designed to last. The carbide-surfaced blades on the stabilizers keep the hole and drillstring centered and on track. Cougar DS places plenty of extra carbide on the leading edge of each blade, where stabilizers wear the most. PREMIUM Tools FOR A TOUGH JOB For complete control, you need tools that will do the job no matter how tough the conditions. You need a stabilizer that stays in gauge and gives precision control of hole direction and angle. You need a rugged and reliable reamer that delivers consistent gauge and low torque. Whether it’s wear resistance or cutting, Cougar DS hardfacing is engineered for the tool and for the job. Our superior materials out-perform all others. Cougar DS roller reamers have precision- made and hardwearing parts that will stand up in even the most abrasive formations. No tool leaves our shop until we’re positive it’s in top condition. We ensure complete traceability and testability by documenting and logging all manufacturing and inspection processes and our tools are suitable for use on DS-1 specification controlled holes. Use our stabilizers and reamers and you’ll quickly discover why Cougar DS tools are considered the best in the industry.

  • Manufacturing Glossary
    MANUFACTURING GLOSSARY Aging – A change in the properties of certain metals and alloys that occurs at ambient or moderately elevated temperatures after a hot-working operation or a heat-treatment (quench aging in ferrous alloys, natural or artificial aging in ferrous and nonferrous alloys) or after a cold-working operation (strain aging). The change in properties is often, but not always, due to a phase change (precipitation), but never involves a change in chemical composition of the metal or alloy. Abrasive – Garnet, emery, carborundum, aluminum oxide, silicon carbide, diamond, cubic boron nitride, or other material in various grit sizes used for grinding, lapping, polishing, honing, pressure blasting, and other operations. Each abrasive particle acts like a tiny, single-point tool that cuts a small chip; with hundreds of thousands of points doing so, high metal-removal rates are possible while providing a good finish. Abrasive Band – Diamond- or other abrasive-coated endless band fitted to a special band machine for machining hard-to-cut materials. Abrasive Belt – Abrasive-coated belt used for production finishing, deburring, and similar functions.See coated abrasive. Abrasive Cutoff Disc – Blade-like disc with abrasive particles that parts stock in a slicing motion. Abrasive Cutoff Machine, Saw – Machine that uses blade-like discs impregnated with abrasive particles to cut/part stock. See saw, sawing machine. Abrasive Flow Machining – Finishing operation for holes, inaccessible areas, or restricted passages. Done by clamping the part in a fixture, then extruding semisolid abrasive media through the passage. Often, multiple parts are loaded into a single fixture and finished simultaneously. Abrasive Machining – Various grinding, honing, lapping, and polishing operations that utilize abrasive particles to impart new shapes, improve finishes, and part stock by removing metal or other material.See grinding.

  • Instruments Used in Endodontics
    Insturments Used in Endodontics The technical demands and level of precision required for sccessful performance of Endodontic procedures is achieved by careful manipula- tion of instruments and by strict adherence to biological and mechanical principles. Although the armamentarium of endodontics has grown in complexity over the past 30 years, yet, the basic instruments used today are not much different from those used at the turn of the century. Classification of endodontic instruments Different classifications for endodontic instruments have been proposed, however, the easiest would be to classify the instruments according to their sequence of usage during performing root canal procedure. I- Diagnostic instruments II- Extirpating instruments III- Enlarging instruments IV- Obturating instruments V- Miscellaneous I- Diagnostic instruments In addition to basic examination instruments (mirror, explorer and twizer) a number of specialized devices are necessary for evaluating the status of the teeth and the surrounding tissues. (1) Visual aids Recently, magnifying elements have been incorporated in the endodontic practice to enhance vision in the operative site. These could be as simple as magnifying loops being attached to ordinary eye glasses giving a mag- nification of 2.5X. Surgical microscopes have recently been adopted in the dental operatories. They offer a wide range of magnification from 2.5-20X together with fiber optic illumination. Operator can work through the eyepiece or a monitor. (2) Vitality testing Clinical assessment of pulp vitality is considered an important aspect in reaching proper diagnosis. This can be achieved by stimulating the neural element or by measuring the vascular conductance. Neural Tests: This is the most popular method for measuring the pulp vitality through thermal or electrical stimulation of the peripheral nerve endings.
