United Abrasives Straight Cartridge Roll | 38062 | 1/2" Diameter | 50 Grit | Sold by Box of 100

United Abrasives 38062 Straight Cartridge Roll provides aggressive sanding action in a compact rotary abrasive configuration. Featuring a 1/2" diameter, 1" length, and 50-grit premium aluminum oxide abrasive, this cartridge roll is well suited to initial surface preparation, coarse deburring, and localized stock removal. Its straight cylindrical profile allows operators to sand channels, fillets, recesses, side walls, and the bottoms of dead-end holes where larger abrasive accessories may be impractical. The coarse 50-grit grain removes material more aggressively than finer cartridge roll options, making it useful for preparing rough metal surfaces before intermediate sanding or finishing. United Abrasives specifies this abrasive family for ferrous metals, non-ferrous metals, stainless steel, and high-tensile steel.

The United Abrasives 38062 features a multi-layer, self-dressing construction that progressively exposes sharp, fresh abrasive grain as each outer layer wears away, helping sustain cutting effectiveness throughout use. Its 1/8" arbor opening corresponds to the manufacturer-specified 95105 cartridge roll mandrel for mounting on compatible rotary tools. The 26,000 maximum RPM rating establishes the abrasive's operating speed limit and helps buyers select an appropriately rated tool and mandrel. Compared with smaller 1/4" and 3/8" cartridge rolls, its 1/2" diameter offers a broader abrasive contact area for accessible recesses and larger internal surfaces. Supplied in a box of 100, this configuration supports repeated deburring and surface preparation tasks in machine shops, fabrication facilities, toolrooms, and industrial maintenance departments.

FAQs:

• Q: What is the United Abrasives 38062 Straight Cartridge Roll primarily used for?
  A: The 38062 is used for coarse sanding, deburring, flash removal, and initial surface preparation on metal components. Its 50-grit abrasive is particularly useful when removing material efficiently is more important than achieving a fine finished surface.
• Q: What is the difference between United Abrasives 38062 and 38063 cartridge rolls?
  A: Both cartridge rolls measure 1/2" in diameter and 1" in length, with a 1/8" arbor opening and 26,000 RPM maximum operating speed. The 38062 uses coarser 50-grit abrasive for more aggressive material removal, while the 38063 uses 60-grit abrasive for a slightly finer sanding pattern.
• Q: Can the 38062 be used to finish stainless steel?
  A: Yes. United Abrasives identifies stainless steel and high-tensile steel among the suitable workpiece materials. The coarse 50-grit abrasive is best suited to initial sanding and deburring; additional finer abrasive steps may be necessary when a smoother final surface is required.
• Q: Which mandrel is recommended for United Abrasives part number 38062?
  A: The United Abrasives catalog specifies mandrel part number 95105 for the 38062 Straight Cartridge Roll. The cartridge roll has a 1/8" arbor opening. Always verify that the mandrel fits the selected rotary tool and meets the applicable operating speed requirements.
• Q: How many cartridge rolls are supplied, and what is their maximum operating speed?
  A: United Abrasives part number 38062 is sold in a box of 100 cartridge rolls. Each roll has a maximum operating speed of 26,000 RPM. The selected rotary tool must not exceed the abrasive's maximum rated speed, and the mandrel must also be appropriate for the operating conditions.
