For blending machining marks and refining longer recessed metal surfaces, the United Abrasives 38133 Straight Cartridge Roll offers intermediate abrasive cutting action across a broad cylindrical working area. Featuring a 1" diameter, 2" abrasive length, and 80-grit premium aluminum oxide grain, this cartridge roll is suitable for removing light burrs, smoothing rough edges, and preparing components for finer finishing. Its straight profile provides contact along channels, internal fillets, side walls, and the bottoms of accessible dead-end holes. The 80-grit abrasive offers a finer scratch pattern than the corresponding 60-grit model, making it useful when the work requires surface refinement rather than aggressive stock removal.
The 38133 incorporates a multi-layer, self-dressing construction, meaning fresh cutting abrasive is exposed as successive layers wear away, helping sustain effective sanding action. Its 1/4" arbor opening requires a correctly matched cartridge roll mandrel for secure installation, and the 18,000 RPM maximum operating speed establishes the upper limit for tool selection. The combination of a 1" diameter and 2" length provides useful abrasive coverage along wider, elongated recesses where adequate clearance is available. Suitable for ferrous metals, non-ferrous metals, stainless steel, and high-tensile steel, the United Abrasives 38133 is supplied in a box of 100 for recurring machining, fabrication, and equipment maintenance operations.

Features:
- Premium aluminum oxide abrasive supports sanding, deburring, and blending on ferrous and non-ferrous metal components.
- 80-grit construction helps reduce residual machining marks and small burrs while producing a finer sanding pattern than coarser grit options.
- 1" diameter offers a broad abrasive contact area for accessible metal cavities, wider channels, and recessed surfaces.
- 2" cylindrical working length provides extended contact along internal walls and grooves where workpiece clearance permits.
- Straight cartridge roll shape is suited to smoothing internal fillets, recesses, side walls, and the bottoms of dead-end holes.
- Multi-layer, self-dressing abrasive exposes sharp, new cutting grain as each layer wears away.
- Quick removal and installation help facilitate roll changes during repeated metal finishing operations.
- Supplied in boxes of 100 for inventory replenishment where cartridge rolls are used regularly.
Applications:
- Machining and CNC finishing - Blending cutter marks and lightly deburring wider internal grooves on machined parts.
- Metal fabrication - Refining recessed edges and local surface irregularities after initial cutting and coarse deburring.
- Tool and die work - Sanding accessible elongated cavities, internal fillets, and tooling recesses.
- Stainless steel and alloy steel finishing - Performing intermediate sanding on stainless steel and high-tensile steel components.
- Machinery refurbishment - Smoothing accessible recessed surfaces on metal fittings, equipment components, and repair parts.
FAQs:
- Q: What is the difference between United Abrasives 38133 and 38132?
A: Both models have a 1" diameter, 2" length, 1/4" arbor opening, and 18,000 RPM maximum operating speed. The 38133 uses 80-grit abrasive for intermediate sanding and surface refinement, whereas the 38132 uses coarser 60-grit abrasive for greater material removal. - Q: How does the 38133 differ from the shorter 38127?
A: Both are 1" diameter, 80-grit cartridge rolls with a 1/4" arbor and 18,000 RPM limit. The 38133 is 2" long, compared with the 1-1/2" length of the 38127. The longer abrasive surface is useful along extended grooves when adequate clearance is available. - Q: Can the 38133 be used for aggressive burr removal?
A: Its 80-grit abrasive is primarily suited to light deburring and intermediate surface blending. For heavier burrs or pronounced machining marks, a coarser grade may be a better starting point before switching to the 38133. - Q: Is United Abrasives 38133 suitable for stainless steel?
A: Yes. United Abrasives identifies stainless steel and high-tensile steel among its suitable workpiece materials. Use abrasives dedicated to stainless steel when avoiding contamination from prior carbon steel work is important. - Q: What mandrel is needed for part number 38133?
A: The roll has a 1/4" arbor opening and requires a compatible cartridge roll mandrel. Confirm the manufacturer's recommended mandrel part number, secure engagement for the 2" roll length, shank fit, and rated speed before use. - Q: How many cartridge rolls are supplied, and what is the maximum speed?
A: The United Abrasives 38133 is sold in a box of 100 straight cartridge rolls. Its maximum operating speed is 18,000 RPM, and the rotary tool and mandrel must comply with the manufacturer's mounting and speed requirements.
