For smoothing machining marks and refining wider recessed metal surfaces after initial deburring, the United Abrasives 38095 Straight Cartridge Roll provides fine abrasive cutting action in a compact cylindrical configuration. Featuring a 5/8" diameter, 1-1/2" length, and 120-grit premium aluminum oxide abrasive, this cartridge roll is suited to light deburring, precision sanding, and surface blending on metal components. Its straight profile allows operators to work along channels, fillets, recesses, side walls, and the bottoms of dead-end holes where conventional abrasive discs may be difficult to position. The 120-grit abrasive produces a finer scratch pattern than the 60- and 80-grit versions, making it useful for reducing marks from earlier sanding operations. United Abrasives identifies ferrous metals, non-ferrous metals, stainless steel, and high-tensile steel as suitable workpiece materials.
The United Abrasives 38095 features a multi-layer, self-dressing construction, meaning fresh cutting abrasive is exposed as successive outer layers wear away, helping maintain effective sanding action during use. Its 1/8" arbor opening corresponds to the manufacturer-specified 95104 cartridge roll mandrel for mounting on compatible rotary tools. With a maximum operating speed of 18,000 RPM, this cartridge roll requires careful speed matching, particularly when used with die grinders capable of higher speeds. The 5/8" diameter provides broader abrasive coverage than smaller cartridge rolls where adequate clearance is available, while the 1-1/2" length allows contact along elongated internal surfaces. Supplied in a box of 100, the 38095 supports recurring fine sanding and finishing requirements in machine shops, toolrooms, metal fabrication facilities, and maintenance departments.

- 1-1/2" straight cylindrical profile enables sanding along elongated channels, fillets, side walls, and the bottoms of dead-end holes.
- Multi-layer, self-dressing construction exposes sharp, new cutting abrasive as successive layers wear away, helping maintain effective sanding performance.
- Suitable for high-speed light deburring and flash removal when operated within the manufacturer's specified 18,000 RPM maximum operating speed.
- Quick removal and installation help minimize interruptions when changing cartridge rolls during multi-stage finishing operations.
- Supplied in boxes of 100 for consistent abrasive stocking and replenishment in machining, fabrication, and maintenance environments.
Applications:
- Precision machining and CNC finishing - Refining machining marks, removing minor residual burrs, and smoothing accessible grooves or recessed surfaces on machined metal components.
- Tool and die manufacturing - Finishing internal fillets, recessed tooling contours, and elongated cavities that require localized abrasive contact.
- Stainless steel fabrication - Performing fine sanding and surface blending on stainless steel and high-tensile steel workpieces following initial material removal.
- Metal component manufacturing - Reducing scratches left by coarser abrasive operations and preparing localized surfaces for additional finishing processes.
- Industrial maintenance and equipment repair - Smoothing minor surface imperfections and refinishing recessed metal areas on machinery components, fittings, and repair parts.
FAQs:
- Q: What is the difference between United Abrasives 38095 and 38094 Straight Cartridge Rolls?
A: Both models feature a 5/8" diameter, 1-1/2" length, 1/8" arbor opening, and maximum operating speed of 18,000 RPM. The 38095 uses finer 120-grit aluminum oxide abrasive for light deburring and surface refinement, while the 38094 uses 80-grit abrasive for intermediate sanding and greater material removal. - Q: Is the United Abrasives 38095 suitable for removing heavy machining burrs?
A: The 120-grit abrasive is better suited to minor burr removal, fine sanding, and surface blending than aggressive stock removal. For pronounced burrs or deeper machining marks, a coarser 60- or 80-grit cartridge roll may be more effective before progressing to the 38095 for surface refinement. - Q: Why choose a 5/8" diameter cartridge roll instead of a smaller size?
A: The 5/8" diameter provides a broader abrasive contact surface for sanding wider grooves and accessible recessed areas. Smaller 1/4", 3/8", or 1/2" cartridge rolls may be preferable when working clearance is limited. Select the diameter according to the workpiece geometry. - Q: Can the United Abrasives 38095 be used on stainless steel?
A: Yes. United Abrasives lists 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 cartridge rolls for stainless steel instead of using abrasives previously applied to carbon steel. - Q: Which mandrel is recommended for United Abrasives part number 38095?
A: The United Abrasives 2025-2026 catalog specifies mandrel part number 95104 for this cartridge roll. The roll has a 1/8" arbor opening. Verify proper mounting engagement, secure installation, and compatibility with the selected rotary tool before operation. - Q: How many cartridge rolls are supplied, and what is the maximum operating speed? A: United Abrasives part number 38095 is sold in a box of 100 cartridge rolls, each with a maximum operating speed of 18,000 RPM. The power tool must not exceed the abrasive's rated speed, and the selected mandrel must also be suitable for the operating conditions.
