United Abrasives Straight Cartridge Roll | 38063 | 1/2" Diameter | 60 Grit | Sold by Box of 100

For smoothing rough edges, removing machining burrs, and blending metal surfaces inside recessed areas, the United Abrasives 38063 Straight Cartridge Roll delivers controlled abrasive cutting action in a compact cylindrical format. Featuring a 1/2" diameter, 1" length, and 60-grit premium aluminum oxide abrasive, this cartridge roll supports general-purpose deburring and initial-to-intermediate surface preparation. Its straight profile provides access to channels, fillets, recesses, side walls, and the bottoms of dead-end holes where larger grinding accessories may be difficult to position. The 60-grit abrasive offers a useful balance between stock removal and surface control, producing a somewhat finer sanding pattern than the coarser 50-grit version. United Abrasives identifies ferrous metals, non-ferrous metals, stainless steel, and high-tensile steel as suitable workpiece materials.

The United Abrasives 38063 incorporates a multi-layer, self-dressing construction, meaning fresh abrasive grain becomes exposed as the outer layers wear away, helping maintain cutting effectiveness during repeated sanding operations. The 1/8" arbor opening corresponds to the manufacturer-specified 95105 cartridge roll mandrel for mounting on compatible rotary tools. With a maximum operating speed of 26,000 RPM, this abrasive supports high-speed deburring and flash removal when operated within its rated limits. Its 1/2" diameter provides a broader contact area than smaller cartridge rolls where sufficient workpiece clearance is available. Supplied in a box of 100, the 38063 supports recurring abrasive requirements in fabrication shops, machining facilities, toolrooms, and industrial maintenance departments.

• Supplied in boxes of 100 for consistent abrasive stocking and replenishment in machining, fabrication, and maintenance environments.

Applications:

• Metal fabrication and welding - Removing small burrs, blending localized surface irregularities, and preparing recessed metal areas for subsequent finishing.
• Machining and CNC workshops - Smoothing machining marks, deburring internal grooves, and refining accessible cavities in machined components.
• Tool and die manufacturing - Sanding recessed contours, internal fillets, and tooling features where a compact rotary abrasive provides better access.
• Stainless steel and alloy steel processing - Performing localized material removal and surface preparation on stainless steel and high-tensile steel parts.
• Industrial maintenance and repair - Cleaning up rough metal edges and surface imperfections during machinery maintenance and component refurbishment.

FAQs:

• Q: What is the difference between United Abrasives 38063 and 38062 Straight Cartridge Rolls?
  A: Both cartridge rolls have a 1/2" diameter, 1" length, 1/8" arbor opening, and 26,000 RPM maximum operating speed. The 38063 uses 60-grit abrasive for general deburring and surface preparation, while the 38062 uses coarser 50-grit abrasive for more aggressive material removal.
• Q: When should I choose a 60-grit cartridge roll instead of an 80-grit version?
  A: A 60-grit cartridge roll is useful for removing burrs, flash, and machining marks when more cutting action is needed. An 80-grit roll is generally better for intermediate sanding and producing a finer surface texture after initial material removal.
• Q: Can the United Abrasives 38063 be used on stainless steel?
  A: Yes. United Abrasives lists stainless steel and high-tensile steel among the suitable materials, along with ferrous and non-ferrous metals. Use abrasives dedicated to stainless steel when avoiding cross-contamination from carbon steel is important.
• Q: Which mandrel is recommended for the United Abrasives 38063?
  A: The manufacturer's catalog identifies mandrel part number 95105 for this cartridge roll. Its arbor opening measures 1/8". Verify correct mandrel fit, secure installation, and compatibility with the selected rotary tool before operation.
• Q: How many cartridge rolls come in a box, and what is their maximum operating speed?
  A: United Abrasives part number 38063 is sold in a box of 100 cartridge rolls, with a maximum operating speed of 26,000 RPM. The tool's maximum speed must not exceed the abrasive's rating, and the mandrel must also be suitable for the intended operating conditions.
