For Rotating or Reciprocating
Description / Application Tough BoyTM
The Casing Scrapers are designed to provide 100% coverage of the inner wall of casing and liners. The 45-degree left and right hand blade design is contoured to the exact fit of the casing. This tool is very effective in the removal of mud cake, cement sheath, pipe scale and shot burrs. The scraper is recommended for use in all drilling applications as well as clean-out / displacement assemblies. The one piece tool body is manufactured from, high-alloy steel and has the highest operating parameters in the industry. The blades are precision cast and surface casehardened to 55-60 HRC. The design allows you to rotate 100 RPM’s or more while milling out cement and delivers reliability, minimum up keep and easy on site maintenance.
It is recommended that this tool be run immediately above the bit on drilling or completion operations. If there is anticipated drilling of landing or float collars then the appropriate milling tool (string, watermelon, etc) should be added to create the proper dress assembly. For completion operations, it is recommended that a full-body casing scraper be spaced to reach bottom of all casings. Tough BoyTM Brush Tools can be spaced above to further scour and prepare casing ID’s for fluid exchange and production equipment. The scraper design is available from 2 3 /8” tubing to 20” casing. Note: Standard scrapers are manufactured to run pin up. This design allows bit or mill to be made up on bottom and orients cutting edge of blades down hole.
