United Abrasives 38043 Straight Cartridge Roll offers precise abrasive contact for detailed finishing operations. Featuring a 3/8" diameter, 1" length, and 120-grit premium aluminum oxide grain, this cartridge roll provides finer sanding action than coarser 60- and 80-grit alternatives. Its straight cylindrical configuration allows operators to reach channels, fillets, recesses, side walls, and the bottoms of dead-end holes where larger abrasive accessories may be difficult to maneuver. Suitable for ferrous metals, non-ferrous metals, stainless steel, and high-tensile steel, the 38043 is a practical choice for intermediate-to-fine surface preparation, light deburring, and blending previously sanded metal components.
The United Abrasives 38043 incorporates a multi-layer, self-dressing construction, which progressively exposes fresh abrasive grain as the outer layers wear away, helping preserve effective cutting action during finishing. Its 1/8" arbor opening corresponds to the manufacturer-specified 95105 cartridge roll mandrel for use with compatible rotary tools. With a maximum operating speed of 26,000 RPM, this abrasive supports high-speed sanding and light flash removal when operated within the manufacturer's speed limits. The 3/8" diameter provides a broader sanding contact area than smaller 1/4" rolls, provided the workpiece has sufficient clearance. Supplied in a box of 100, the 38043 accommodates recurring finishing requirements in machine shops, metal fabrication facilities, toolrooms, and industrial maintenance operations.
Type: Straight Cartridge Roll | Part Number: 38043 | Abrasive Material: Premium Aluminum Oxide | Diameter: 3/8" | Length: 1" | Arbor: 1/8" | Grit: 120 | Max RPM: 26,000 | Mandrel Part Number: 95105 | Quantity: 100 per Box | Material Application: Ferrous Metals, Non-Ferrous Metals, Stainless Steel, High-Tensile Steel
Features:
- Premium aluminum oxide abrasive grain supports controlled sanding, blending, and finishing on ferrous and non-ferrous metal surfaces.
- Fine 120-grit abrasive helps reduce sanding marks and refine workpiece surfaces following coarser abrasive operations.
- 3/8" diameter provides a useful abrasive contact area for recessed metal features while allowing localized finishing.
- 1" straight cylindrical construction facilitates sanding along narrow channels, fillets, side walls, and the bottoms of dead-end holes.
- Multi-layer, self-dressing construction exposes sharp, new cutting abrasive as successive layers wear away, helping maintain sanding effectiveness.
- Suitable for high-speed deburring and flash removal where a finer abrasive finish is preferred over aggressive stock removal.
- Quick removal and installation simplify abrasive replacement during multi-stage metal finishing operations.
- Supplied in boxes of 100 to support repeated sanding and surface preparation tasks in machining and fabrication environments.
Applications:
- Precision machining and CNC finishing - Refining tool marks, smoothing minor burrs, and improving surface texture inside accessible machined grooves and recesses.
- Tool and die manufacturing - Finishing small cavities, internal fillets, and recessed metal contours that require localized abrasive contact.
- Stainless steel fabrication - Performing fine sanding and blending on stainless steel and high-tensile steel components after initial surface preparation.
- Metal component manufacturing - Reducing scratches from earlier sanding operations and refining small metal features before subsequent finishing processes.
- Industrial maintenance and repair - Cleaning up minor surface imperfections on machine components, fittings, and recessed repair areas.
FAQs:
- Q: What is the difference between United Abrasives 38043 and 38041 Straight Cartridge Rolls?
A: Both cartridge rolls have a 3/8" diameter, 1" length, 1/8" arbor opening, and 26,000 RPM maximum operating speed. The 38043 uses finer 120-grit abrasive for surface refinement and light deburring, while the 38041 features 80-grit abrasive for more substantial material removal and intermediate sanding. - Q: Is the United Abrasives 38043 suitable for removing heavy burrs?
A: The 120-grit configuration is better suited to light burr removal and surface blending than aggressive stock removal. For pronounced burrs or deeper machining marks, a coarser grit may be more efficient before using the 38043 to refine the surface. - Q: Can this cartridge roll be used for stainless steel finishing?
A: Yes. United Abrasives identifies stainless steel and high-tensile steel among the suitable materials. When contamination control is important, use abrasives dedicated to stainless steel rather than rolls previously used on carbon steel. - Q: Which mandrel is specified for the United Abrasives 38043?
A: The United Abrasives catalog identifies mandrel part number 95105 for this cartridge roll. The roll has a 1/8" arbor opening. Confirm secure mounting, rotary tool compatibility, and the applicable operating speed limits before use. - Q: How many cartridge rolls are supplied, and what is their maximum operating speed?
A: United Abrasives part number 38043 is sold in a box of 100 cartridge rolls, each rated for a maximum operating speed of 26,000 RPM. The rotary tool must not exceed the abrasive's maximum rated speed, and the selected mandrel must also be suitable for the operating conditions.
