For deburring wider internal grooves, removing machining marks, and preparing recessed metal surfaces, the United Abrasives 38093 Straight Cartridge Roll provides controlled abrasive cutting with a broader cylindrical working area. Featuring a 5/8" diameter, 1-1/2" length, and 60-grit premium aluminum oxide abrasive, this cartridge roll is suited to coarse-to-intermediate sanding, flash removal, and blending localized surface irregularities. The straight profile allows abrasive contact along channels, fillets, recessed contours, side walls, and the bottoms of dead-end holes. Compared with smaller-diameter rolls, the 5/8" configuration provides greater abrasive surface coverage where workpiece clearance permits, making it useful for sanding accessible internal features without switching to larger grinding wheels. United Abrasives identifies ferrous metals, non-ferrous metals, stainless steel, and high-tensile steel as suitable workpiece materials.
The United Abrasives 38093 incorporates a multi-layer, self-dressing construction that exposes fresh cutting abrasive as successive layers wear away, helping maintain effective sanding action during use. Its 1/8" arbor opening corresponds to the manufacturer-listed 95104 cartridge roll mandrel for mounting on compatible rotary tools. This model has a maximum operating speed of 18,000 RPM, an important distinction from smaller cartridge rolls in the family rated at 26,000 RPM. Operators must select equipment that does not exceed the abrasive's rated speed. The 1-1/2" length provides useful contact along extended internal walls, while the 60-grit abrasive supports material removal before progressing to finer finishing grades. Supplied in a box of 100, the 38093 supports recurring deburring and surface preparation requirements in machining, fabrication, toolroom, and industrial maintenance operations.

FAQs:
- Q: What is the United Abrasives 38093 Straight Cartridge Roll used for?
A: The 38093 is used for sanding, deburring, flash removal, and surface blending in recessed metalworking areas. Its 5/8" diameter and 60-grit abrasive provide useful cutting coverage for accessible grooves and internal surfaces where initial material removal is required. - Q: What is the difference between United Abrasives 38093 and 38094 cartridge rolls?
A: Both models have a 5/8" diameter, 1-1/2" length, 1/8" arbor opening, and 18,000 RPM maximum operating speed. The 38093 uses 60-grit abrasive for more aggressive deburring, while the 38094 uses finer 80-grit abrasive for intermediate sanding and surface refinement. - Q: Why is the 38093 rated for 18,000 RPM instead of 26,000 RPM?
A: United Abrasives specifies an 18,000 RPM maximum operating speed for this 5/8" diameter model, compared with 26,000 RPM for certain smaller cartridge rolls. The manufacturer's speed rating must be followed regardless of the tool's available speed. Do not operate the 38093 above 18,000 RPM. - Q: Can the United Abrasives 38093 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 cartridge rolls dedicated to stainless steel when preventing cross-contamination from carbon steel is important. Finer grits may be needed for a smoother final finish. - Q: Which mandrel is specified for United Abrasives part number 38093?
A: The United Abrasives 2025-2026 catalog identifies mandrel part number 95104 for this cartridge roll. The roll has a 1/8" arbor opening. Confirm secure mounting, appropriate mandrel engagement, and compatibility with the selected rotary tool and operating speed before use. - Q: How many cartridge rolls are supplied, and what is their maximum operating speed?
A: United Abrasives part number 38093 is sold in a box of 100 cartridge rolls, each with a maximum rated operating speed of 18,000 RPM. The tool must not exceed the abrasive's speed limit, and the mandrel must also be rated appropriately for the operating conditions.
