For removing machining burrs, cleaning up rough metal edges, and preparing elongated recessed surfaces, the United Abrasives 38087 Straight Cartridge Roll delivers coarse-to-intermediate abrasive cutting action with an extended cylindrical working profile. Featuring a 1/2" diameter, 2" length, and 60-grit premium aluminum oxide abrasive, this cartridge roll is suitable for sanding internal channels, grooves, fillets, side walls, and the bottoms of accessible dead-end holes. The 60-grit construction provides effective material removal for deburring and blending rough machining marks before finer finishing operations. Its 1/2" diameter offers a balance between abrasive contact area and access to relatively narrow workpiece features.
The United Abrasives 38087 uses a multi-layer, self-dressing construction that exposes fresh cutting grain as successive abrasive layers wear away, helping maintain effective sanding action. A defining specification is its 3/16" arbor opening, which distinguishes this model from the otherwise similar 38080 cartridge roll with a 1/8" arbor. The larger arbor opening must be matched with an appropriately sized cartridge roll mandrel for secure mounting. Its 26,000 RPM maximum operating speed establishes the abrasive's upper speed limit, while the 2" abrasive length provides contact along extended internal surfaces where working clearance permits. Suitable workpiece materials include ferrous metals, non-ferrous metals, stainless steel, and high-tensile steel. The 38087 is supplied in a box of 100 for recurring machining, fabrication, and maintenance applications.

- Industrial equipment maintenance - Preparing recessed metal fittings and machinery parts for further finishing or refurbishment.
FAQs:
- Q: What is the difference between United Abrasives 38087 and 38080?
A: Both cartridge rolls have a 1/2" diameter, 2" length, 60-grit aluminum oxide abrasive, and 26,000 RPM maximum operating speed. The key difference is the arbor opening: the 38087 has a 3/16" arbor, while the 38080 has a 1/8" arbor. Select the model that matches the intended mounting arrangement. - Q: When should I choose a 60-grit cartridge roll instead of 80 grit?
A: Choose 60 grit when removing noticeable burrs, rough machining marks, or localized flash is the priority. An 80-grit roll, such as the United Abrasives 38088, offers a finer sanding pattern for intermediate surface blending. - Q: What is the benefit of the 2" abrasive length?
A: The longer profile provides additional abrasive contact along extended grooves and internal walls. Workpiece clearance and correct mandrel engagement remain important, particularly when accessing deeper or restricted areas. - Q: Can United Abrasives 38087 be used on stainless steel?
A: Yes. United Abrasives identifies stainless steel and high-tensile steel as suitable materials, along with ferrous and non-ferrous metals. Use separate abrasives for stainless steel when preventing contamination from previous carbon steel work is important. - Q: What mandrel is required for part number 38087?
A: The 38087 has a 3/16" arbor opening and requires a compatible cartridge roll mandrel. Confirm the manufacturer's recommended mandrel part number, secure mounting engagement, and compatibility with the selected rotary tool before use. - Q: What is the maximum operating speed, and how many rolls come in a box?
A: United Abrasives specifies a maximum operating speed of 26,000 RPM for the 38087. The product is sold in a box of 100 straight cartridge rolls. Any mounting accessories should be verified separately.
