For removing burrs, smoothing rough machining marks, and preparing larger recessed metal surfaces, the United Abrasives 38132 Straight Cartridge Roll combines a broad cylindrical sanding surface with an extended working length. Featuring a 1" diameter, 2" length, and 60-grit premium aluminum oxide abrasive, this cartridge roll is suited to coarse-to-intermediate sanding, flash removal, and localized surface blending. Its straight profile provides abrasive contact along internal channels, fillets, side walls, recessed contours, and the bottoms of accessible dead-end holes. The 60-grit abrasive offers effective cutting action for removing machining irregularities before progressing to finer abrasive grades.
The United Abrasives 38132 features a multi-layer, self-dressing construction that exposes fresh, sharp abrasive grain as successive layers wear away, helping maintain cutting effectiveness during use. Its 1/4" arbor opening requires a correctly matched cartridge roll mandrel for secure mounting on compatible rotary equipment. The 18,000 RPM maximum operating speed establishes the abrasive's upper speed limit and must be considered when selecting a die grinder and mounting accessory. Compared with shorter 1" diameter cartridge rolls, the 2" abrasive length provides additional contact along extended internal surfaces where sufficient clearance is available. Suitable for ferrous metals, non-ferrous metals, stainless steel, and high-tensile steel, the 38132 is supplied in a box of 100 for recurring metalworking operations.

FAQs:
- Q: What is the difference between United Abrasives 38132 and 38126 Straight Cartridge Rolls? A: Both models feature a 1" diameter, 60-grit aluminum oxide abrasive, 1/4" arbor opening, and 18,000 RPM maximum operating speed. The 38132 is 2" long, while the 38126 measures 1-1/2" long. The longer model provides additional abrasive contact along extended internal surfaces where adequate clearance is available.
- Q: When should I choose the 60-grit 38132 instead of an 80-grit roll? A: Choose the 38132 when noticeable burrs, machining marks, or rough surfaces still require material removal. The 80-grit United Abrasives 38133 offers a finer sanding pattern for intermediate blending after initial deburring.
- Q: Is a 1" diameter cartridge roll appropriate for narrow openings? A: The 1" diameter is better suited to wider recesses and openings that provide sufficient working clearance. Smaller cartridge rolls may be preferable for narrow grooves or confined features where the larger abrasive cannot fit.
- Q: Can United Abrasives 38132 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 dedicated abrasives for stainless steel when avoiding cross-contamination from previous carbon steel work is important.
- Q: What mandrel does the United Abrasives 38132 require? A: This model has a 1/4" arbor opening and requires a compatible cartridge roll mandrel. Confirm the manufacturer's recommended mandrel part number, appropriate engagement for the 2" roll length, shank compatibility, and speed rating before use.
- Q: What is the maximum operating speed, and how many cartridge rolls are supplied? A: United Abrasives 38132 has a maximum operating speed of 18,000 RPM and is sold in a box of 100 straight cartridge rolls. The selected rotary tool and mandrel must comply with the manufacturer's mounting and speed requirements.
