For intermediate sanding inside elongated grooves, machined recesses, and narrow metal channels, the United Abrasives 38088 Straight Cartridge Roll combines an extended cylindrical abrasive surface with controlled material removal. Featuring a 1/2" diameter, 2" length, and 80-grit premium aluminum oxide abrasive, this roll is suited to light deburring, blending machining marks, and refining surfaces after coarse sanding. The straight configuration provides abrasive contact along internal side walls, fillets, recesses, and the bottoms of accessible dead-end holes. Its 80-grit construction helps produce a finer sanding pattern than 60-grit alternatives while retaining enough cutting action for removing minor burrs and surface irregularities.
A key distinction of the United Abrasives 38088 is its 3/16" arbor opening, which differs from the 1/8" arbor used on the otherwise similarly sized 38081 model. The manufacturer lists mandrel part number 95106 for the 38088, providing a specific mounting reference when selecting compatible rotary tool accessories. The multi-layer, self-dressing construction exposes sharp, new cutting abrasive as successive layers wear away, helping maintain effective sanding action. With a maximum operating speed of 26,000 RPM, the roll must be used with appropriately rated equipment. Suitable for ferrous metals, non-ferrous metals, stainless steel, and high-tensile steel, this configuration is supplied in a box of 100 for recurring machining, fabrication, and maintenance work.
Type: Straight Cartridge Roll | Part Number: 38088 | Abrasive Material: Premium Aluminum Oxide | Diameter: 1/2" | Length: 2" | Arbor: 3/16" | Grit: 80 | Max RPM: 26,000 | Mandrel Part Number: 95106 | Quantity: 100 per Box | Material Application: Ferrous Metals, Non-Ferrous Metals, Stainless Steel, High-Tensile Steel
Features:
- Premium aluminum oxide grain provides abrasive cutting action for deburring, blending, and finishing ferrous and non-ferrous metal surfaces.
- 80-grit abrasive helps smooth light machining marks and residual burrs while producing a finer scratch pattern than coarser abrasive grades.
- 1/2" diameter offers access to relatively narrow grooves and recessed areas without sacrificing the useful contact of a cylindrical abrasive.
- Extended 2" length provides additional sanding contact along elongated channels and internal walls where sufficient clearance is available.
- Straight cartridge roll profile supports work along fillets, side walls, recesses, and the bottoms of accessible dead-end holes.
- Multi-layer, self-dressing construction progressively exposes fresh cutting grain as the abrasive wears.
- 3/16" arbor configuration matches the manufacturer-listed 95106 mandrel, helping distinguish it from similar rolls with smaller arbor openings.
- Quick removal and installation simplify roll replacement, while the box quantity of 100 supports repeated sanding operations.
Applications:
- Machining and CNC finishing - Blending cutter marks and removing small burrs along longer internal grooves and machined recesses.
- Tool and die manufacturing - Refining accessible tooling channels, recessed contours, and internal fillets requiring localized abrasive contact.
- Metal fabrication - Smoothing rough edges and blending surface imperfections after initial cutting or coarse deburring.
- Stainless steel component processing - Performing intermediate surface preparation on stainless steel and high-tensile steel parts.
- Industrial equipment repair - Refining accessible recessed features on machinery components and metal fittings during repair or refurbishment.
FAQs:
- Q: What is the difference between United Abrasives 38088 and 38081?
A: Both models have a 1/2" diameter, 2" length, 80-grit abrasive, and 26,000 RPM maximum operating speed. The main distinction is the arbor size: the 38088 has a 3/16" arbor and uses the manufacturer-listed 95106 mandrel, while the 38081 has a 1/8" arbor. - Q: How does the 38088 compare with the 60-grit 38087?
A: Both rolls share the same dimensions and 3/16" arbor configuration. The 38088 uses 80-grit abrasive for intermediate sanding and surface blending, whereas the 38087 uses coarser 60-grit abrasive for more aggressive burr and material removal. - Q: Is the 38088 suitable for final polishing?
A: The 80-grit abrasive is intended for intermediate sanding and blending rather than producing a polished finish. For a finer surface, use progressively finer abrasive grades as required by the workpiece and finishing specification. - Q: Can United Abrasives 38088 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. To avoid cross-contamination, use abrasives dedicated to stainless steel when necessary. - Q: Which mandrel should be used with part number 38088?
A: The United Abrasives catalog lists mandrel part number 95106 for this 3/16" arbor cartridge roll. Verify correct engagement, mandrel shank compatibility, and applicable speed limits before mounting. - Q: What is the maximum RPM and packaging quantity?
A: The 38088 has a maximum operating speed of 26,000 RPM and is sold in a box of 100 straight cartridge rolls. Confirm any mounting accessory requirements separately.
