United Abrasives 38008 Straight Cartridge Roll provides controlled sanding and blending in areas difficult to access with conventional abrasive discs. Featuring a 1/4" diameter, 1" length, and 80-grit premium aluminum oxide abrasive, this cartridge roll combines effective material removal with a more refined sanding action than coarser 60-grit alternatives. Its straight cylindrical configuration helps operators work along channels, fillets, recesses, side walls, and the bottoms of dead-end holes. Suitable for ferrous metals, non-ferrous metals, stainless steel, and high-tensile steel, the 38008 is a practical option for removing minor machining burrs, blending localized surface imperfections, and preparing metal components for subsequent finishing operations.
The United Abrasives 38008 uses a multi-layer, self-dressing construction, meaning fresh cutting abrasive becomes exposed as the outer layers wear away. This helps maintain effective sanding action throughout the abrasive's usable life. Its 1/8" arbor opening is matched to the manufacturer-listed 95105 cartridge roll mandrel for installation on compatible rotary tools. With a maximum operating speed of 26,000 RPM, the roll supports high-speed deburring and flash removal when operated within the manufacturer's specified limits. Packaged in a box of 100, this configuration offers a convenient supply of consistent-size abrasives for machining departments, metal fabrication shops, toolrooms, and maintenance facilities performing repeated surface preparation tasks.

- Supplied in boxes of 100 to support routine abrasive replenishment and inventory management in metalworking environments.
Applications:
- Precision machining and CNC workshops - Removing small machining burrs, blending tool marks, and refining localized surfaces inside machined components.
- Metal fabrication - Smoothing cut edges, preparing narrow joints, and blending surface imperfections before additional finishing operations.
- Tool and die maintenance - Sanding internal corners, small cavities, fillets, and recessed metal features with limited abrasive access.
- Stainless steel component finishing - Performing localized sanding and deburring on stainless steel and high-tensile steel workpieces.
- Industrial maintenance and repair - Cleaning and refining small metal surfaces on machinery components, fittings, and repair parts.
FAQs:
- Q: What is the difference between United Abrasives 38008 and 38007 Straight Cartridge Rolls?
A: Both cartridge rolls have a 1/4" diameter, 1" length, and 26,000 RPM maximum operating speed. The 38008 features 80-grit abrasive for intermediate sanding and surface blending, while the 38007 uses coarser 60-grit abrasive for more aggressive initial material removal. - Q: Is the United Abrasives 38008 suitable for stainless steel finishing?
A: Yes. United Abrasives identifies stainless steel and high-tensile steel among the suitable materials for this cartridge roll. For work requiring contamination control, use abrasives dedicated to stainless steel rather than products previously used on carbon steel. - Q: Which mandrel is recommended for the United Abrasives 38008?
A: The manufacturer's catalog identifies cartridge roll mandrel part number 95105. The 38008 has a 1/8" arbor opening. Verify that the selected mandrel is compatible with the power tool and appropriate for the intended operating conditions. - Q: When should I choose an 80-grit cartridge roll instead of 120 grit?
A: An 80-grit cartridge roll is useful when the work requires moderate material removal, deburring, and surface blending. A finer 120-grit cartridge roll is generally preferable when reducing sanding marks and achieving a more refined finish are the primary objectives. - Q: How many cartridge rolls come in a box, and what is their maximum rated speed?
A: United Abrasives part number 38008 is supplied in a box quantity of 100, with a maximum operating speed of 26,000 RPM. Ensure the rotary tool does not exceed the abrasive's rated speed and that the mandrel is properly secured before use.
