For deburring metal components and smoothing rough surfaces inside elongated recesses, the United Abrasives 38048 Straight Cartridge Roll delivers concentrated abrasive cutting action with an extended cylindrical working surface. Featuring a 3/8" diameter, 1-1/2" length, and 60-grit premium aluminum oxide abrasive, this cartridge roll supports initial surface preparation, machining burr removal, and blending of localized metal imperfections. Its straight profile allows operators to sand channels, fillets, recesses, side walls, and the bottoms of dead-end holes where larger grinding and sanding accessories may have limited access. The 60-grit abrasive provides effective material removal while producing a somewhat finer scratch pattern than the coarser 50-grit alternative. United Abrasives identifies ferrous metals, non-ferrous metals, stainless steel, and high-tensile steel as suitable workpiece materials.
The United Abrasives 38048 incorporates a multi-layer, self-dressing construction that exposes fresh cutting abrasive as successive layers wear away, helping maintain sanding effectiveness throughout use. Its 1/8" arbor opening corresponds to the manufacturer-listed 95104 cartridge roll mandrel for installation on a compatible rotary tool. The 26,000 maximum RPM rating establishes the abrasive's upper operating speed limit and must be considered when selecting the tool and mounting accessory. Compared with the shorter United Abrasives 38040, the 38048 provides an additional 1/2" of abrasive length for sanding extended grooves and internal side walls while retaining the same diameter and grit. Supplied in a box of 100, this configuration supports recurring surface preparation and deburring requirements in machining facilities, metal fabrication shops, toolrooms, and industrial maintenance departments.

- Industrial maintenance and equipment repair - Removing rough edges and localized surface imperfections from accessible recessed areas on machinery components and fittings.
FAQs:
- Q: What is the difference between United Abrasives 38048 and 38047 Straight Cartridge Rolls?
A: Both cartridge rolls feature a 3/8" diameter, 1-1/2" length, 1/8" arbor opening, and 26,000 RPM maximum operating speed. The 38048 uses 60-grit aluminum oxide abrasive for coarse deburring and surface preparation, while the 38047 uses coarser 50-grit abrasive for more aggressive material removal. - Q: How does the United Abrasives 38048 compare with the 38040 cartridge roll?
A: Both models have a 3/8" diameter and 60-grit abrasive. The 38048 measures 1-1/2" long, compared with the 1" length of the 38040. The longer roll offers additional abrasive contact length for elongated grooves and accessible internal walls, provided sufficient clearance is available. - Q: Is the 38048 suitable for finishing stainless steel?
A: Yes. United Abrasives lists stainless steel and high-tensile steel among the suitable workpiece materials. The 60-grit abrasive is useful for initial sanding and deburring; finer grits may be needed to achieve a smoother final surface. Reserve separate abrasives for stainless steel when preventing cross-contamination from carbon steel is important. - Q: Which mandrel is recommended for the United Abrasives 38048?
A: The United Abrasives 2025-2026 catalog lists cartridge roll mandrel part number 95104 for SKU 38048. The roll has a 1/8" arbor opening. Verify the mandrel's mounting engagement, shank compatibility, and operating speed suitability before installation. - Q: How many rolls come in a box, and what is the maximum operating speed?
A: United Abrasives part number 38048 is supplied in a box of 100 cartridge rolls, each with a maximum rated operating speed of 26,000 RPM. The tool's maximum speed must not exceed the abrasive's rated speed, and the mandrel must also be suitable for the intended operating conditions.
