For smoothing machining marks, blending rough edges, and refining recessed metal surfaces, the United Abrasives 38114 Straight Cartridge Roll provides controlled abrasive cutting action for intermediate sanding and deburring. Featuring a 3/4" diameter, 1-1/2" length, and 80-grit premium aluminum oxide abrasive, this cartridge roll offers a useful balance between material removal and surface refinement. Its straight cylindrical profile allows operators to work along channels, fillets, internal side walls, recesses, and the bottoms of dead-end holes where conventional sanding discs may not provide effective access. Compared with the coarser 40- and 60-grit options, the 80-grit abrasive produces a finer sanding pattern while retaining cutting action for removing residual burrs and surface imperfections. Suitable materials include ferrous metals, non-ferrous metals, stainless steel, and high-tensile steel.
The United Abrasives 38114 incorporates a multi-layer, self-dressing construction that exposes fresh, sharp abrasive grain as successive layers wear away, helping maintain effective sanding action during use. Its 3/16" arbor opening requires a properly matched cartridge roll mandrel for secure installation on a compatible rotary tool. The 18,000 maximum RPM rating establishes the abrasive's operating speed limit and is particularly important when selecting a die grinder capable of operating at higher speeds. Its 3/4" diameter provides broader abrasive coverage than smaller cartridge rolls where sufficient clearance is available, while the 1-1/2" length allows contact along extended internal surfaces. Supplied in a box of 100, the 38114 supports recurring deburring, surface blending, and intermediate finishing requirements in machining facilities, fabrication shops, toolrooms, and industrial maintenance departments.

- 1-1/2" straight profile provides working coverage along internal side walls, fillets, channels, and the bottoms of dead-end holes.
- Multi-layer, self-dressing construction exposes fresh cutting abrasive as successive layers wear away, helping maintain sanding effectiveness.
- 18,000 RPM maximum operating speed provides an important reference for selecting an appropriately rated rotary tool and mandrel.
- Quick removal and installation help reduce interruptions when replacing cartridge rolls between finishing operations.
- Supplied in boxes of 100 to accommodate routine abrasive replenishment in fabrication, machining, and maintenance environments.
Applications:
- Precision machining and CNC workshops - Smoothing tool marks, removing residual burrs, and refining accessible internal grooves on machined metal components.
- Metal fabrication and finishing - Blending localized surface imperfections and preparing recessed metal areas for subsequent finishing processes.
- Tool and die manufacturing - Sanding internal fillets, tooling cavities, and recessed contours where a cylindrical abrasive provides useful working contact.
- Stainless steel and alloy steel processing - Performing intermediate sanding and localized surface blending on stainless steel and high-tensile steel workpieces.
- Industrial maintenance and repair - Cleaning rough edges and refining recessed surfaces on machinery components, metal fittings, and repair parts.
FAQs:
- Q: What is the difference between United Abrasives 38114 and 38113 Straight Cartridge Rolls?
A: Both models have a 3/4" diameter, 1-1/2" length, 3/16" arbor opening, and 18,000 RPM maximum operating speed. The 38114 uses finer 80-grit abrasive for intermediate sanding and surface blending, while the 38113 uses 60-grit abrasive for more aggressive burr removal and surface preparation. - Q: Is the United Abrasives 38114 suitable for removing heavy machining burrs?
A: The 80-grit configuration is better suited to minor burr removal, smoothing machining marks, and intermediate surface finishing. For pronounced burrs or substantial material removal, a coarser 40- or 60-grit cartridge roll may be more effective before progressing to the 38114. - Q: Can the 38114 cartridge roll 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 abrasives dedicated to stainless steel when preventing cross-contamination from carbon steel is important. - Q: What type of mandrel does the United Abrasives 38114 require?
A: The cartridge roll has a 3/16" arbor opening and requires a cartridge roll mandrel with a compatible mounting diameter. Verify the manufacturer's recommended mandrel part number, secure mounting engagement, and tool compatibility before ordering. - Q: Can I use the United Abrasives 38114 with a 25,000 RPM die grinder?
A: No. The abrasive has a maximum operating speed of 18,000 RPM. Do not mount it on a tool whose maximum rated speed exceeds the cartridge roll's speed limit, even if the tool can be operated at a lower speed. - Q: How many cartridge rolls are supplied in a box?
A: United Abrasives part number 38114 is sold in a box of 100 straight cartridge rolls. Confirm mandrel requirements and package contents separately before ordering accessories.
