For removing light burrs and blending machining marks across recessed metal surfaces, the United Abrasives 38094 Straight Cartridge Roll offers intermediate-grit sanding with a wider cylindrical contact area. Featuring a 5/8" diameter, 1-1/2" length, and 80-grit premium aluminum oxide abrasive, this cartridge roll is suited to smoothing internal grooves, refining previously prepared metal surfaces, and cleaning up localized imperfections. Its straight profile provides abrasive contact along channels, fillets, side walls, recesses, and the bottoms of dead-end holes where conventional sanding discs may be difficult to position. The 80-grit abrasive produces a finer scratch pattern than the 60-grit version while maintaining useful cutting action for general metal finishing. United Abrasives lists ferrous metals, non-ferrous metals, stainless steel, and high-tensile steel as suitable workpiece materials.
The United Abrasives 38094 features 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 accommodates the corresponding cartridge roll mandrel, while the 18,000 maximum RPM rating establishes the abrasive's upper operating speed limit. This lower speed rating is important when comparing the 5/8" model with smaller cartridge rolls rated for 26,000 RPM. The 1-1/2" abrasive length provides contact along extended internal surfaces, while the broader diameter helps cover accessible recessed areas where sufficient clearance is available. Supplied in a box of 100, the 38094 supports recurring sanding and deburring requirements in machining, fabrication, toolroom, and maintenance environments.

Applications:
- Machining and CNC workshops - Blending machining marks, removing residual burrs, and smoothing wider internal grooves on machined metal components.
- Metal fabrication and finishing - Refining localized surface imperfections and preparing recessed metal areas for subsequent finishing operations.
- Tool and die maintenance - Sanding accessible internal fillets, recessed contours, and tooling cavities with a cylindrical abrasive.
- Stainless steel and alloy steel processing - Performing intermediate sanding and surface blending on stainless steel and high-tensile steel workpieces.
- Industrial equipment maintenance - Cleaning up minor surface irregularities on metal fittings, machinery components, and repair areas with sufficient working clearance.
FAQs:
- Q: How does United Abrasives 38094 compare with the 38093 Straight Cartridge Roll?
A: Both models have a 5/8" diameter, 1-1/2" length, 1/8" arbor opening, and 18,000 RPM maximum operating speed. The 38094 uses 80-grit abrasive for intermediate sanding and surface refinement, while the 38093 uses coarser 60-grit abrasive for greater material removal. - Q: When is an 80-grit cartridge roll preferable to 120 grit?
A: An 80-grit roll is useful when moderate cutting action is still required to remove small burrs or blend visible machining marks. A 120-grit roll is better suited to finer surface refinement after the initial sanding work is complete. - Q: Can the United Abrasives 38094 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 dedicated abrasives where preventing contamination from previous carbon steel work is important. - Q: What maximum tool speed can be used with the 38094?
A: This cartridge roll has a maximum operating speed of 18,000 RPM. Do not use it on a rotary tool whose maximum operating speed exceeds that rating, and verify that the selected mandrel is also suitable for the intended operating conditions. - Q: What mandrel is specified for the United Abrasives 38094?
A: The United Abrasives catalog identifies mandrel part number 95104 for the 1/8" arbor configuration. Check the mandrel's mounting engagement, shank compatibility, and speed rating before installation. - Q: How many cartridge rolls are supplied with SKU 38094?
A: The listed selling quantity is 100 straight cartridge rolls per box. Confirm any separately required mounting accessories before ordering.
