For refining long, narrow grooves and smoothing recessed metal surfaces after initial deburring, the United Abrasives 38017 Straight Cartridge Roll provides fine abrasive cutting action with additional working length for detailed finishing. Featuring a 1/4" diameter, 1-1/2" length, and 120-grit premium aluminum oxide abrasive, this cartridge roll is suited to removing minor burrs, reducing machining marks, and blending previously sanded surfaces. Its straight cylindrical profile allows abrasive contact along channels, fillets, recesses, side walls, and the bottoms of dead-end holes. The 120-grit abrasive produces a finer scratch pattern than 60- or 80-grit alternatives, making it useful for surface refinement rather than aggressive stock removal. Suitable workpiece materials include ferrous metals, non-ferrous metals, stainless steel, and high-tensile steel.
The United Abrasives 38017 incorporates a multi-layer, self-dressing construction that exposes fresh cutting abrasive as successive layers wear away, helping sustain effective sanding action during use. Its 1/8" arbor opening corresponds to the manufacturer-specified 95104 cartridge roll mandrel for use with compatible rotary tools. The 26,000 maximum RPM rating establishes the abrasive's upper operating speed limit and must be considered when matching the roll with a tool and mandrel. Compared with the shorter 1" United Abrasives 38010, this model offers an additional 1/2" of abrasive length for finishing extended internal surfaces without increasing the roll diameter. Supplied in a box of 100, the 38017 supports recurring precision sanding and surface preparation work in machine shops, fabrication facilities, toolrooms, and industrial maintenance departments.

Features:
- Premium aluminum oxide abrasive grain provides effective sanding and finishing action on ferrous and non-ferrous metals.
- 120-grit abrasive supports light deburring, fine surface blending, and refinement of machining marks left by earlier operations.
- 1/4" diameter permits access to narrow grooves, recessed openings, and internal workpiece features where larger abrasives cannot fit.
- 1-1/2" straight cylindrical profile provides an extended abrasive working surface for sanding along internal side walls, channels, and fillets.
- Multi-layer, self-dressing construction exposes sharp, new cutting abrasive as each layer wears away, helping maintain effective sanding performance.
- Suitable for high-speed deburring and flash removal when operated within the manufacturer's specified maximum speed rating.
- Quick removal and installation help reduce interruptions when changing cartridge rolls during multi-step finishing operations.
- Supplied in boxes of 100 for consistent abrasive stocking and replenishment across machining, fabrication, and maintenance environments.
Applications:
- Precision machining and CNC finishing - Refining machining marks, removing minor burrs, and smoothing elongated internal grooves on machined metal components.
- Tool and die manufacturing - Finishing narrow tooling recesses, internal fillets, and detailed metal contours where additional abrasive length is beneficial.
- Stainless steel fabrication - Performing localized fine sanding and surface blending on stainless steel and high-tensile steel workpieces.
- Metal component production - Reducing scratches left by coarser abrasives and preparing recessed surfaces for subsequent finishing operations.
- Industrial maintenance and repair - Smoothing minor imperfections and refining narrow metal features on machinery components, fittings, and repair parts.
FAQs:
- Q: What is the difference between United Abrasives 38017 and 38015 Straight Cartridge Rolls?
A: Both models feature a 1/4" diameter, 1-1/2" length, 1/8" arbor, and 26,000 RPM maximum operating speed. The 38017 uses finer 120-grit abrasive for light deburring and surface refinement, while the 38015 uses 80-grit abrasive for greater material removal and intermediate sanding. - Q: How does the 38017 compare with the shorter 38010 cartridge roll?
A: Both cartridge rolls have a 1/4" diameter and 120-grit aluminum oxide abrasive. The 38017 is 1-1/2" long, compared with the 1" length of the 38010. The longer configuration provides more abrasive contact length for sanding extended grooves and accessible internal walls. - Q: Is 120 grit appropriate for removing heavy machining burrs?
A: The 120-grit abrasive is more suitable for light burr removal, smoothing, and surface refinement than aggressive stock removal. For larger burrs or rough machining marks, begin with a coarser abrasive before using the 38017 to improve the surface finish. - Q: Can the United Abrasives 38017 be used on stainless steel?
A: Yes. United Abrasives identifies stainless steel and high-tensile steel among the suitable materials, along with ferrous and non-ferrous metals. When contamination control is important, use cartridge rolls dedicated to stainless steel rather than abrasives previously used on carbon steel. - Q: Which mandrel is recommended for the United Abrasives 38017?
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 mandrel fit, secure installation, and compatibility with the selected rotary tool before operation. - Q: How many cartridge rolls are supplied, and what is the maximum rated speed?
A: United Abrasives part number 38017 is sold in a box of 100 cartridge rolls, with a maximum operating speed of 26,000 RPM. The power tool must not exceed the abrasive's speed rating, and the mandrel must also be suitable for the intended operating conditions.
