For smoothing machining marks, removing residual burrs, and refining wider recessed metal surfaces, the United Abrasives 38127 Straight Cartridge Roll provides controlled abrasive cutting action with a broad cylindrical sanding surface. Featuring a 1" diameter, 1-1/2" length, and 80-grit premium aluminum oxide abrasive, this cartridge roll is suited to intermediate sanding, deburring, and surface blending where a balance between material removal and finish quality is required. Its straight cylindrical profile allows operators to work along channels, fillets, internal side walls, recesses, and the bottoms of dead-end holes where conventional abrasive discs may not provide effective contact. Compared with the coarser 60-grit version, the 80-grit abrasive produces a finer sanding pattern while retaining the cutting action needed to smooth minor surface imperfections. Suitable workpiece materials include ferrous metals, non-ferrous metals, stainless steel, and high-tensile steel.
The United Abrasives 38127 features a multi-layer, self-dressing construction that progressively exposes sharp, fresh abrasive grain as successive layers wear away, helping maintain effective sanding action during use. Its 1/4" arbor opening corresponds to the manufacturer-listed 95102 cartridge roll mandrel for installation on compatible rotary tools. With a maximum operating speed of 18,000 RPM, this abrasive requires careful tool and mandrel selection, particularly when working with die grinders capable of higher speeds. The 1" diameter provides broader abrasive coverage than smaller cartridge rolls where adequate clearance is available, while the 1-1/2" length offers useful contact along extended internal surfaces. Supplied in a box of 100, the 38127 supports recurring deburring and finishing requirements in machining facilities, fabrication shops, toolrooms, and industrial maintenance departments.

Applications:
- Precision machining and CNC workshops - Smoothing machining marks, removing small residual burrs, and refining wider internal grooves on machined metal components.
- Metal fabrication and finishing - Blending rough edges, reducing localized surface imperfections, and preparing recessed metal areas for subsequent finishing operations.
- Tool and die manufacturing - Sanding accessible tooling cavities, internal fillets, and recessed contours where a larger 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 components.
- Industrial maintenance and equipment repair - Cleaning up minor surface irregularities and preparing recessed machinery components, metal fittings, and repair areas for further finishing.
FAQs:
- Q: What is the difference between United Abrasives 38127 and 38126 Straight Cartridge Rolls?
A: Both models feature a 1" diameter, 1-1/2" length, 1/4" arbor opening, and 18,000 RPM maximum operating speed. The 38127 uses finer 80-grit aluminum oxide abrasive for intermediate sanding and surface refinement, while the 38126 uses 60-grit abrasive for more aggressive deburring and material removal. - Q: When should I choose the 38127 instead of a 120-grit cartridge roll?
A: The 80-grit 38127 is useful when minor burrs or visible machining marks still require material removal. A 120-grit cartridge roll, such as United Abrasives 38128, is generally better suited to finer sanding and surface refinement after the initial blending work is complete. - Q: Is the United Abrasives 38127 suitable for stainless steel?
A: Yes. United Abrasives identifies stainless steel and high-tensile steel among the suitable workpiece materials, along with ferrous and non-ferrous metals. When preventing cross-contamination is important, reserve separate abrasives for stainless steel rather than using cartridge rolls previously applied to carbon steel. - Q: Which mandrel is recommended for United Abrasives part number 38127?
A: The United Abrasives 2025-2026 catalog identifies mandrel part number 95102 for this cartridge roll. The 38127 has a 1/4" arbor opening. Verify proper mounting engagement, secure installation, and compatibility with the selected rotary tool before operation. - Q: Can the United Abrasives 38127 be used with a 25,000 RPM die grinder?
A: No. The cartridge roll has a maximum operating speed of 18,000 RPM. Do not mount it on a tool whose maximum rated speed exceeds the abrasive's rating, even if the tool can be operated at a lower speed. Choose a properly rated tool and mandrel combination. - Q: How many cartridge rolls are supplied in a box?
A: United Abrasives part number 38127 is sold in a box of 100 straight cartridge rolls. The manufacturer identifies mandrel 95102 for mounting, but confirm accessory inclusion separately before ordering.
