United Abrasives 38013 Straight Cartridge Roll provides a compact solution for precision sanding, surface blending, and light deburring. Featuring a 1/4" diameter, 1" length, and 320-grit premium aluminum oxide abrasive, this cartridge roll is suited to fine surface refinement on ferrous metals, non-ferrous metals, stainless steel, and high-tensile steel. The straight cylindrical profile allows controlled abrasive contact along narrow channels, fillets, recesses, side walls, and the bottoms of dead-end holes. Its fine 320-grit abrasive produces a less aggressive cutting action than 60-, 80-, or 120-grit alternatives, making it particularly useful for reducing sanding marks and refining metal surfaces following earlier material removal operations.
The United Abrasives 38013 features a multi-layer, self-dressing construction that exposes fresh abrasive grain as successive layers wear away, helping maintain effective sanding action during use. Its 1/8" arbor opening corresponds to the manufacturer-listed 95105 cartridge roll mandrel for use with a compatible rotary tool. The 26,000 maximum RPM rating establishes the abrasive's operating speed limit, which must be considered alongside the mandrel and tool ratings. Supplied in a box of 100, this configuration supports recurring fine-finishing requirements in machine shops, toolrooms, metal fabrication facilities, and maintenance departments where consistent abrasive dimensions and surface finish control are important.

- Fine 320-grit abrasive helps reduce visible scratches and refine surface textures after coarser sanding operations.
- Compact 1/4" diameter provides abrasive access to narrow grooves, small openings, and recessed metal features.
- 1" straight cylindrical construction facilitates localized finishing along channels, fillets, side walls, and the bottoms of dead-end holes.
- Multi-layer, self-dressing construction exposes sharp, new cutting abrasive as each layer wears away, helping maintain abrasive effectiveness.
- Suitable for high-speed deburring and flash removal within the manufacturer's specified operating speed limits, particularly where light material removal is required.
- Quick removal and installation allow convenient abrasive changes during multi-stage finishing operations.
- Supplied in boxes of 100 for convenient inventory management and repeated precision metal-finishing tasks.
Applications:
- Precision machining and CNC finishing - Refining fine machining marks and smoothing small internal surfaces after initial deburring operations.
- Tool and die manufacturing - Finishing narrow recesses, fillets, and intricate metal contours where larger abrasive accessories cannot reach.
- Stainless steel fabrication - Fine sanding and surface blending on stainless steel and high-tensile steel components prior to subsequent finishing processes.
- Metal component finishing - Reducing scratches from earlier abrasive operations and improving localized surface texture on fabricated or machined parts.
- Industrial maintenance and repair - Light deburring and detailed surface cleanup on small metal fittings, recessed components, and equipment repair areas.
FAQs:
- Q: What is the United Abrasives 38013 Straight Cartridge Roll best used for?
A: The 38013 is suited to fine sanding, scratch refinement, and light deburring in confined metalworking areas. Its 320-grit abrasive is useful when improving an existing surface finish is more important than removing substantial amounts of material. - Q: How does the 38013 differ from the 38010 cartridge roll?
A: Both models share a 1/4" diameter, 1" length, 1/8" arbor, and 26,000 RPM maximum operating speed. The 38013 uses finer 320-grit abrasive for surface refinement, while the 38010 uses 120-grit abrasive for more noticeable material removal and intermediate finishing. - Q: Can the 38013 cartridge roll produce a polished metal finish?
A: The 320-grit abrasive can help create a finer, more uniform sanded surface than coarser cartridge rolls. However, a mirror or high-gloss finish may require additional finer abrasives or polishing compounds, depending on the workpiece material and desired result. - Q: Which mandrel fits United Abrasives part number 38013?
A: The manufacturer's catalog identifies mandrel part number 95105 for this cartridge roll. The roll has a 1/8" arbor opening. Check that the mandrel fits the rotary tool and is rated appropriately before use. - Q: What is the maximum operating speed, and how many rolls are supplied?
A: United Abrasives lists the 38013 with a maximum operating speed of 26,000 RPM and a quantity of 100 cartridge rolls per box. The tool's maximum speed must not exceed the abrasive's rated speed.
