United Abrasives Straight Cartridge Roll | 38081 | 1/2" Diameter | 80 Grit | Sold by Box of 100

For refining machining marks, blending rough edges, and smoothing elongated internal grooves, the United Abrasives 38081 Straight Cartridge Roll provides intermediate abrasive cutting action in an extended cylindrical configuration. Featuring a 1/2" diameter, 2" length, and 80-grit premium aluminum oxide abrasive, this cartridge roll is designed for light deburring, surface blending, and sanding recessed metal areas where conventional abrasive discs may be difficult to position. The 80-grit abrasive offers a finer scratch pattern than the 60-grit alternative, making it useful for refining surfaces after initial material removal. Its straight profile provides contact along channels, fillets, side walls, recesses, and the bottoms of accessible dead-end holes.

The United Abrasives 38081 features a multi-layer, self-dressing construction, which exposes fresh cutting abrasive as successive layers wear away to help maintain effective sanding action. Its 1/8" arbor opening accommodates a compatible cartridge roll mandrel, while the 26,000 RPM maximum operating speed establishes the abrasive's upper speed limit. The 2" abrasive length offers additional working contact along extended internal surfaces compared with shorter cartridge rolls of the same diameter, provided adequate clearance is available. Suitable for ferrous metals, non-ferrous metals, stainless steel, and high-tensile steel, the 38081 is supplied in a box of 100 for ongoing machining, fabrication, and maintenance operations.

Features:

• Premium aluminum oxide abrasive grain supports intermediate sanding, deburring, and surface blending on ferrous and non-ferrous metals.
• 80-grit abrasive helps reduce machining marks, small burrs, and scratches left by coarser sanding operations.
• 1/2" diameter provides a useful balance of abrasive contact area and access to relatively narrow recessed features.
• Extended 2" length enables sanding along elongated internal channels and side walls where sufficient working clearance is available.
• Straight cylindrical design is suited to channels, fillets, recesses, and the bottoms of accessible dead-end holes.
• Multi-layer, self-dressing construction exposes sharp, new cutting abrasive as each layer wears away, helping maintain sanding effectiveness.
• Quick removal and installation help simplify abrasive replacement during repeated finishing operations.
• Box quantity of 100 supports routine abrasive replenishment in metalworking facilities.

Applications:

• Precision machining and CNC finishing - Smoothing tool marks and removing residual burrs along elongated internal grooves and machined channels.
• Metal fabrication - Blending localized surface imperfections and refining recessed edges after initial cutting or deburring.
• Tool and die work - Sanding accessible tooling recesses, internal fillets, and longer contoured features requiring cylindrical abrasive contact.
• Stainless steel and alloy steel finishing - Performing intermediate sanding on stainless steel and high-tensile steel components.
• Industrial equipment maintenance - Refining accessible recessed surfaces on machinery parts, metal fittings, and repair components.

FAQs:

• Q: How does United Abrasives 38081 differ from 38080?
  A: Both models have a 1/2" diameter, 2" length, 1/8" arbor, and 26,000 RPM maximum operating speed. The 38081 uses 80-grit abrasive for intermediate sanding and finer surface blending, while the 38080 uses coarser 60-grit abrasive for greater material removal.
• Q: What is the advantage of the 2" abrasive length?
  A: The longer profile provides additional contact along extended grooves and internal side walls. Shorter rolls may be preferable for shallow recesses or areas with restricted access.
• Q: Is the 38081 suitable for heavy burr removal?
  A: Its 80-grit abrasive is better suited to light deburring and intermediate surface preparation. For pronounced burrs or heavier stock removal, a coarser cartridge roll may be more effective before finishing with the 38081.
• Q: Can this cartridge roll be used on stainless steel?
  A: Yes. United Abrasives lists stainless steel and high-tensile steel among the suitable materials. Use separate abrasives for stainless steel when preventing cross-contamination from carbon steel is important.
• Q: What mandrel does the United Abrasives 38081 require?
  A: It has a 1/8" arbor opening and requires a compatible cartridge roll mandrel. Confirm the manufacturer's recommended mandrel, adequate engagement for the 2" roll length, and tool compatibility before use.
• Q: How many rolls are supplied, and what is their maximum operating speed?
  A: The 38081 is sold in a box of 100 straight cartridge rolls, each with a maximum operating speed of 26,000 RPM. The selected tool and mandrel must comply with the manufacturer's speed and mounting requirements.
