When machined metal components require smoother contours and reduced surface marks inside extended recesses, the United Abrasives 38333 Tapered Cartridge Roll provides controlled intermediate sanding in a pointed abrasive configuration. Featuring a 5/8" base diameter, 2" length, and 80-grit premium aluminum oxide abrasive, this cartridge roll is designed for blending machining marks, removing light burrs, and refining metal surfaces after initial material removal. Its full-taper profile narrows toward the tip, allowing the abrasive to reach angled channels, internal fillets, recessed corners, and irregular contours where a straight cartridge roll may be less effective. The 80-grit abrasive delivers a finer sanding pattern than the 60-grit alternative while retaining cutting action for intermediate surface preparation.
The United Abrasives 38333 features a multi-layer, self-dressing construction that exposes fresh cutting grain as successive abrasive layers wear away. This helps maintain effective sanding action during repeated metal finishing tasks. The roll has a 1/8" arbor opening, and the manufacturer's catalog references cartridge roll mandrel 95103 for mounting. Its 18,000 RPM maximum operating speed must be considered when selecting a compatible die grinder and mandrel, particularly because smaller cartridge rolls may have higher speed ratings. The 2" abrasive length allows contact along extended recessed contours where adequate clearance is available, while the tapered end supports focused sanding around angled features. Suitable workpiece materials include ferrous metals, non-ferrous metals, stainless steel, and high-tensile steel. The 38333 is supplied in a box of 100.

Features:
- Premium aluminum oxide abrasive grain supports sanding, deburring, and surface blending on ferrous and non-ferrous metal components.
- 80-grit construction helps reduce residual machining marks and minor burrs while leaving a finer scratch pattern than coarser 60-grit rolls.
- Full-taper design directs abrasive contact into angled recesses, internal fillets, and contoured openings that require a narrowing working profile.
- 5/8" base diameter provides useful contact on accessible recessed surfaces while allowing more concentrated sanding toward the tip.
- Extended 2" abrasive length accommodates longer internal contours and channels where workpiece geometry provides sufficient clearance.
- Multi-layer, self-dressing construction continually exposes fresh abrasive grain as successive layers wear away.
- 1/8" arbor opening corresponds to the manufacturer-referenced 95103 cartridge roll mandrel for appropriately matched mounting.
- Quick removal and installation help streamline abrasive replacement during repetitive metal finishing operations.
- Box quantity of 100 supports consistent abrasive stocking for machining, fabrication, and repair work.
Applications:
- Precision machining and CNC finishing Blending cutter marks and small burrs along angled pockets, internal fillets, and recessed machined contours.
- Tool and die work Refining accessible tapered cavities, tooling corners, and elongated internal surfaces after initial deburring.
- Metal fabrication Smoothing localized rough edges and reducing surface marks around contoured openings and irregular metal features.
- Stainless steel and alloy steel finishing Performing intermediate sanding on recessed stainless steel and high-tensile steel components.
- Machinery maintenance Refining accessible internal grooves, angled fittings, and contoured metal repair surfaces.
FAQs:
- Q: What is the difference between United Abrasives 38333 and 38332? A: Both models have a 5/8" base diameter, 2" length, 1/8" arbor opening, and 18,000 RPM maximum operating speed. The 38333 uses 80-grit abrasive for intermediate sanding and surface refinement, while the 38332 uses coarser 60-grit abrasive for greater material removal.
- Q: How does SKU 38333 compare with the 1/2" diameter 38327? A: Both rolls are 2" long and feature 80-grit aluminum oxide with a 1/8" arbor opening. The 38333 has a 5/8" base diameter and an 18,000 RPM rating, while the narrower 38327 has a 1/2" base diameter and a 26,000 RPM rating. Selection depends on recess clearance, desired abrasive contact area, and tool compatibility.
- Q: Is 80 grit appropriate for removing heavy burrs? A: The 38333 is better suited to smaller burrs, intermediate sanding, and blending residual machining marks. For more pronounced burrs and rough surfaces, a coarser option such as the 60-grit 38332 may be preferable for initial material removal.
- Q: Can the 38333 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 abrasives dedicated to stainless steel where preventing cross-contamination from carbon steel is necessary.
- Q: Why does a tapered cartridge roll work well in angled recesses? A: Its profile gradually narrows toward the tip, helping position abrasive contact along sloped surfaces, internal fillets, and irregular corners. Straight cartridge rolls maintain a cylindrical shape that may be more useful on parallel side walls.
- Q: Which mandrel is recommended for United Abrasives 38333? A: The United Abrasives 20252026 catalog lists cartridge roll mandrel 95103 for this 1/8" arbor, 2" long configuration. Confirm correct mounting engagement, tool shank fit, and speed compatibility before operation.
- Q: What are the operating speed and packaging quantity? A: United Abrasives 38333 has a maximum operating speed of 18,000 RPM and is sold in a box of 100 tapered cartridge rolls. Mounting accessory requirements should be checked separately.
