For removing machining burrs, smoothing rough edges, and preparing elongated angled recesses, the United Abrasives 38326 Tapered Cartridge Roll provides targeted abrasive cutting action with an extended, narrowing working profile. Featuring a 1/2" base diameter, 2" length, and 60-grit premium aluminum oxide abrasive, this cartridge roll is suited to deburring, flash removal, and coarse-to-intermediate surface blending. Its full-taper design gradually narrows toward the tip, helping operators reach internal fillets, angled channels, recessed corners, and irregular metal contours where a straight cylindrical roll may be difficult to position. The 60-grit abrasive provides effective material removal for addressing surface imperfections before progressing to finer finishing grades.
The United Abrasives 38326 features a multi-layer, self-dressing construction, meaning fresh cutting abrasive is exposed as successive layers wear away, helping maintain effective sanding action throughout use. Its 1/8" arbor opening corresponds to the manufacturer-listed 95103 cartridge roll mandrel for appropriately matched mounting. With a maximum operating speed of 26,000 RPM, the abrasive must be used with compatible rotary equipment that meets its speed and mounting requirements. The extended 2" length provides additional abrasive contact along deeper angled recesses compared with shorter tapered cartridge rolls, provided sufficient working clearance is available. United Abrasives identifies ferrous metals, non-ferrous metals, stainless steel, and high-tensile steel as suitable workpiece materials. The 38326 is supplied in a box of 100 for recurring machining, fabrication, and industrial maintenance applications.

- Full-taper design narrows toward the tip, allowing abrasive contact in angled recesses, internal corners, fillets, and contoured workpiece features.
- 1/2" base diameter provides useful sanding coverage near the wider end of the roll while allowing more focused contact toward the tip.
- Extended 2" abrasive length offers additional working contact along elongated angled grooves and deeper recessed contours.
- Multi-layer, self-dressing construction exposes sharp, new abrasive grain as successive layers wear away, helping maintain cutting effectiveness.
- 1/8" arbor opening corresponds to the manufacturer-listed 95103 cartridge roll mandrel for correctly matched mounting.
- Quick removal and installation facilitate abrasive changes, while the box quantity of 100 supports regular inventory replenishment.
Applications:
- Machining and CNC operations Removing burrs and blending cutter marks along elongated angled openings, recessed pockets, and internal fillets.
- Tool and die manufacturing Sanding accessible tooling cavities, tapered features, and deeper internal contours requiring a narrowing abrasive profile.
- Metal fabrication Cleaning up localized cutting flash and rough edges around recessed or irregularly shaped metal components.
- Stainless steel and alloy steel processing Performing initial deburring and surface preparation on contoured stainless steel and high-tensile steel workpieces.
- Industrial equipment maintenance Preparing accessible recessed fittings, internal corners, and angled metal repair surfaces for subsequent finishing.
FAQs:
- Q: How does United Abrasives 38326 differ from the 38319 Tapered Cartridge Roll? A: Both models feature a 1/2" base diameter, 60-grit aluminum oxide abrasive, 1/8" arbor opening, and 26,000 RPM maximum operating speed. The 38326 is 2" long and lists mandrel 95103, while the 38319 is 1-1/2" long and lists mandrel 95104. The longer model provides additional working contact along extended recessed contours where clearance permits.
- Q: Should I choose the 60-grit 38326 or the finer 80-grit 38327? A: Choose the 38326 when removing noticeable burrs, flash, or machining marks is the main requirement. The 80-grit 38327 offers a finer sanding pattern for intermediate surface blending after initial material removal.
- Q: What advantage does the tapered design offer for deburring? A: Its narrowing abrasive profile helps reach angled corners, internal fillets, and contoured recesses. Straight cartridge rolls maintain a uniform cylindrical surface and may be more suitable for sanding parallel side walls or straight channels.
- Q: Can United Abrasives 38326 be used on stainless steel? A: Yes. United Abrasives identifies stainless steel and high-tensile steel among the suitable workpiece materials, along with ferrous and non-ferrous metals. Use abrasives dedicated to stainless steel when preventing contamination from previous carbon steel work is important.
- Q: Which mandrel is recommended for United Abrasives part number 38326? A: The United Abrasives 20252026 catalog identifies mandrel part number 95103 for this 1/8" arbor, 2" long tapered cartridge roll. Verify proper mounting engagement, secure installation, shank compatibility, and applicable speed limits before use.
- Q: What are the maximum operating speed and packaging quantity? A: United Abrasives 38326 has a maximum operating speed of 26,000 RPM and is sold in a box of 100 tapered cartridge rolls. Confirm any mounting accessory requirements and package contents separately before ordering.
