For deburring longer internal grooves, blending machining marks, and preparing recessed metal surfaces, the United Abrasives 38080 Straight Cartridge Roll provides a combination of abrasive coverage and extended working length. Featuring a 1/2" diameter, 2" length, and 60-grit premium aluminum oxide abrasive, this cylindrical roll is designed for sanding, deburring, and flash removal where a conventional abrasive disc cannot easily reach. The 60-grit grain provides coarse-to-intermediate cutting action for removing unwanted material before finer finishing, while the straight profile helps operators work along channels, fillets, internal side walls, recesses, and the bottoms of accessible dead-end holes.
The 38080 uses a multi-layer, self-dressing construction, meaning fresh abrasive grain is exposed as successive layers wear away, helping sustain cutting effectiveness. Its 1/8" arbor opening accepts an appropriately matched cartridge roll mandrel for use with compatible rotary equipment. The 26,000 RPM maximum operating speed establishes the upper speed limit for the abrasive, making tool and mandrel compatibility essential. Compared with the shorter 1-1/2" version, the 2" length offers additional abrasive contact along elongated internal surfaces where clearance permits. Suitable for ferrous metals, non-ferrous metals, stainless steel, and high-tensile steel, the 38080 is supplied in a box of 100 for regular machining, fabrication, and maintenance work.

- Extended 2" abrasive length provides contact along longer internal walls and channels compared with shorter cartridge rolls.
- Straight cylindrical design helps reach fillets, recessed side walls, and the bottoms of accessible dead-end holes.
- Multi-layer, self-dressing construction exposes fresh abrasive grain as successive layers wear away.
- Quick removal and installation help simplify abrasive replacement during repetitive sanding tasks.
- Box quantity of 100 supports routine inventory replenishment for machining and metal fabrication operations.
Applications:
- Machining and CNC operations - Removing burrs and blending tool marks along elongated internal grooves and recessed machined surfaces.
- Metal fabrication - Cleaning up cutting flash, rough edges, and localized imperfections in accessible channels and openings.
- Tool and die work - Sanding internal fillets, tooling recesses, and longer contoured features that require cylindrical abrasive contact.
- Stainless steel and alloy steel processing - Performing localized deburring and preliminary surface preparation on stainless steel and high-tensile steel components.
- Industrial equipment maintenance - Preparing accessible recessed metal areas and smoothing surface irregularities on machinery parts and fittings.
FAQs:
- Q: How does the United Abrasives 38080 compare with the 38073?
A: Both cartridge rolls feature a 1/2" diameter, 60-grit aluminum oxide abrasive, 1/8" arbor opening, and 26,000 RPM maximum speed. The 38080 is 2" long, while the 38073 is 1-1/2" long. Choose the longer roll when additional abrasive working length is useful and the workpiece provides sufficient clearance. - Q: Should I choose 60 grit or 80 grit for deburring?
A: The 60-grit 38080 is suitable when removing noticeable burrs, flash, or machining marks is the priority. The 80-grit 38081 is better suited to intermediate sanding and producing a finer scratch pattern after initial material removal. - Q: Can the 38080 be used to sand stainless steel?
A: Yes. United Abrasives identifies stainless steel and high-tensile steel as suitable workpiece materials. When avoiding cross-contamination is important, use separate cartridge rolls for stainless steel rather than abrasives previously used on carbon steel. - Q: What type of mandrel is needed for SKU 38080?
A: The 38080 has a 1/8" arbor opening and requires a compatible cartridge roll mandrel. Confirm the recommended mandrel part number, mounting engagement, tool fit, and applicable speed rating before use. - Q: What is the maximum operating speed of the United Abrasives 38080?
A: The manufacturer lists a maximum operating speed of 26,000 RPM. The selected rotary tool must not exceed the abrasive's rated speed, and the mandrel must also be suitable for the operating conditions. - Q: How many rolls are supplied with part number 38080?
A: The 38080 is sold in a box of 100 straight cartridge rolls. Mandrel inclusion has not been confirmed in the available product information.
