United Abrasives 38041 Straight Cartridge Roll provides a practical balance between material removal and surface refinement. This cylindrical abrasive features a 3/8" diameter, 1" length, and 80-grit premium aluminum oxide grain for intermediate sanding, smoothing machining marks, and blending localized surface imperfections. Its straight profile permits abrasive contact along side walls, fillets, narrow recesses, and the bottoms of dead-end holes. Compared with a coarser 60-grit cartridge roll, the 80-grit configuration produces a finer sanding pattern while retaining useful cutting action for general metalworking applications. United Abrasives identifies ferrous metals, non-ferrous metals, stainless steel, and high-tensile steel among the suitable workpiece materials.
The United Abrasives 38041 incorporates a multi-layer, self-dressing construction, which exposes fresh cutting abrasive as the outer layers gradually wear away. This design helps maintain abrasive effectiveness during repeated deburring and finishing operations. The 1/8" arbor opening allows installation using an appropriately sized cartridge roll mandrel, while the 26,000 maximum RPM rating establishes the upper operating speed limit for safe tool selection. The 3/8" diameter offers a larger abrasive contact area than smaller 1/4" rolls when sufficient clearance is available. Supplied in a box of 100, this configuration is suited to machining departments, metal fabrication shops, maintenance facilities, and toolrooms requiring repeatable abrasive dimensions and grit selection.

Features:
- Premium aluminum oxide abrasive grain supports sanding, deburring, and surface blending on ferrous and non-ferrous metals.
- 80-grit abrasive provides intermediate cutting action for removing minor burrs, refining machining marks, and preparing metal surfaces for subsequent finishing.
- 3/8" diameter offers a practical abrasive contact area for recessed surfaces and internal features with sufficient working clearance.
- 1" straight cylindrical profile allows sanding along channels, fillets, side walls, and the bottoms of dead-end holes.
- Multi-layer, self-dressing construction exposes sharp, new cutting abrasive as successive layers wear away, helping maintain effective sanding action.
- Suitable for high-speed deburring and flash removal when operated within the manufacturer's specified maximum speed rating.
- Quick removal and installation help limit interruptions when replacing abrasive rolls during metal finishing operations.
- Box quantity of 100 supports planned abrasive replenishment for machining, fabrication, and industrial maintenance workflows.
Applications:
- Machining and CNC workshops - Blending machining marks, removing small burrs, and refining accessible internal grooves and recesses on machined components.
- Metal fabrication - Smoothing localized imperfections, preparing narrow metal surfaces, and blending areas following initial abrasive work.
- Tool and die maintenance - Sanding internal fillets, recessed contours, and small cavities that require a compact rotary abrasive.
- Stainless steel and alloy steel finishing - Performing intermediate sanding and surface blending on stainless steel and high-tensile steel workpieces.
- Industrial equipment repair - Cleaning up minor surface irregularities and preparing recessed metal components for inspection or additional finishing.
FAQs:
- Q: What is the difference between United Abrasives 38041 and 38040 Straight Cartridge Rolls?
A: Both models have a 3/8" diameter, 1" length, 1/8" arbor opening, and 26,000 RPM maximum operating speed. The 38041 uses 80-grit abrasive for intermediate sanding and surface blending, while the 38040 features coarser 60-grit abrasive for more aggressive material removal. - Q: When should I choose a 3/8" cartridge roll instead of a 1/4" cartridge roll?
A: A 3/8" cartridge roll offers a broader abrasive contact area when the workpiece has adequate clearance. A smaller 1/4" diameter is generally preferable for narrower channels and openings where the larger roll cannot fit. - Q: Is the United Abrasives 38041 suitable for stainless steel?
A: Yes. United Abrasives lists stainless steel and high-tensile steel as suitable materials, along with ferrous and non-ferrous metals. For applications where surface contamination is a concern, use abrasives dedicated to stainless steel rather than rolls previously used on carbon steel. - Q: What mandrel can be used with the United Abrasives 38041?
A: United Abrasives mandrel part number 95105 has a 1/8" mounting diameter and 1/4" shank, making it a dimensional match for the cartridge roll's 1/8" arbor opening. Confirm proper fit, mandrel speed rating, and rotary tool compatibility before operation. - Q: How many cartridge rolls are supplied, and what is their maximum operating speed?
A: United Abrasives part number 38041 is sold in a box of 100 cartridge rolls, each with a maximum operating speed of 26,000 RPM. The power tool must not exceed the abrasive's rated operating speed, and the selected mandrel must also be suitable for the operating conditions.
