For precision sanding and surface refinement inside larger metal recesses, the United Abrasives 38134 Straight Cartridge Roll combines fine abrasive cutting action with an extended cylindrical working surface. Featuring a 1" diameter, 2" length, and 120-grit premium aluminum oxide abrasive, this cartridge roll is suited to light deburring, blending machining marks, and reducing scratches left by coarser abrasives. Its straight profile provides contact along internal channels, fillets, recessed side walls, and the bottoms of accessible dead-end holes. The 120-grit abrasive offers a finer sanding pattern than the corresponding 60- and 80-grit models, making it a useful choice for later stages of metal surface preparation.
United Abrasives uses a multi-layer, self-dressing construction, meaning fresh abrasive grain is exposed as successive layers wear away to help maintain cutting effectiveness. The 1/4" arbor opening requires a correctly matched cartridge roll mandrel for secure installation on a compatible die grinder or rotary tool. Its 18,000 RPM maximum operating speed establishes the abrasive's upper speed limit, while the 2" abrasive length provides working contact along elongated internal surfaces where clearance permits. The 1" diameter offers a broader contact area than smaller cartridge rolls but requires sufficient room inside the workpiece. Suitable for ferrous metals, non-ferrous metals, stainless steel, and high-tensile steel, the 38134 is supplied in a box of 100 for recurring finishing operations.

FAQs:
- Q: How does United Abrasives 38134 differ from 38133?
A: Both models have a 1" diameter, 2" length, 1/4" arbor opening, and 18,000 RPM maximum operating speed. The 38134 uses finer 120-grit abrasive for surface refinement, while the 38133 uses 80-grit abrasive for intermediate sanding and greater material removal. - Q: What is the difference between the 38134 and 38128 cartridge rolls?
A: Both use a 1" diameter, 120-grit aluminum oxide abrasive, and 1/4" arbor opening. The 38134 is 2" long, while the 38128 is 1-1/2" long. Choose the longer roll when additional abrasive contact is useful and sufficient working clearance is available. - Q: Is the 38134 suitable for heavy burr removal?
A: Its 120-grit abrasive is more appropriate for light deburring, fine sanding, and scratch refinement than aggressive stock removal. For substantial burrs or rough machining marks, begin with a coarser cartridge roll before progressing to the 38134. - Q: Can United Abrasives 38134 be used on stainless steel?
A: Yes. United Abrasives lists stainless steel and high-tensile steel among the suitable workpiece materials. Use abrasives dedicated to stainless steel when preventing contamination from previous carbon steel work is important. - Q: What mandrel is required for SKU 38134?
A: The 38134 has a 1/4" arbor opening and requires a compatible cartridge roll mandrel. Confirm the manufacturer's recommended mandrel part number, secure mounting engagement, shank compatibility, and applicable speed rating before use. - Q: How many cartridge rolls are supplied, and what is their maximum operating speed?
A: United Abrasives part number 38134 is sold in a box of 100 straight cartridge rolls. Each roll has a maximum operating speed of 18,000 RPM, and the selected power tool and mandrel must comply with the manufacturer's speed and mounting requirements.
