When wide internal grooves, machining recesses, and metal cavities require substantial burr removal, the United Abrasives 38119 Straight Cartridge Roll offers aggressive sanding with an extended cylindrical contact surface. This model combines a 3/4" diameter, 2" abrasive length, and 40-grit premium aluminum oxide abrasive for coarse surface preparation and localized material removal. Its straight shape helps reach side walls, internal fillets, channels, and the bottoms of accessible dead-end holes. The coarse abrasive grain is particularly useful for cutting down rough machining marks and flash before progressing to finer grits.
The 38119 features a multi-layer, self-dressing construction, meaning new abrasive grain is exposed as successive layers wear away to help maintain cutting action. Its 3/16" arbor opening is paired with the manufacturer-listed 95106 cartridge roll mandrel, while its 18,000 RPM maximum operating speed determines the permissible tool speed. Compared with the shorter 38112 model, the 2" length offers additional abrasive contact along elongated internal surfaces where clearance permits. Suitable applications include sanding ferrous metals, non-ferrous metals, stainless steel, and high-tensile steel. Each purchase is a box of 100 cartridge rolls for recurring machining, fabrication, and metalworking operations.

- Metal fabrication - Cleaning up localized cutting flash and preparing recessed metal edges for further finishing.
- Tool and die manufacturing - Coarse sanding of wider tooling cavities, internal fillets, and elongated recessed features.
- Stainless steel and alloy steel work - Initial deburring and abrasive surface preparation on stainless steel and high-tensile steel components.
- Industrial repair - Removing localized roughness from accessible machinery recesses, metal fittings, and repair areas.
FAQs:
- Q: How does the United Abrasives 38119 differ from the 38112?
A: Both are 3/4" diameter, 40-grit straight cartridge rolls with a 3/16" arbor and an 18,000 RPM maximum speed. The 38119 is 2" long and lists mandrel 95106, while the 38112 is 1-1/2" long and lists mandrel 95107. Choose based on the working length needed and available clearance. - Q: When is 40 grit preferable to 60 grit?
A: Choose 40 grit for heavier burr removal, rough surface leveling, or more aggressive initial sanding. The 60-grit United Abrasives 38120 provides a finer scratch pattern when less material removal is needed. - Q: Is the 38119 intended for final finishing?
A: No. Its coarse 40-grit abrasive is primarily useful for initial material removal. Additional sanding with finer grits may be required to achieve the specified surface finish. - Q: Which mandrel is recommended for SKU 38119?
A: The manufacturer's catalog lists cartridge roll mandrel part number 95106 for the 3/16" arbor and 2" length configuration. Confirm proper fit, secure mounting, and tool compatibility before operation. - Q: Can the 38119 be used on stainless steel?
A: Yes. United Abrasives lists stainless steel among the suitable metals. Reserve dedicated abrasives for stainless steel when preventing contamination from previous carbon steel work is important. - Q: What is the maximum operating speed and box quantity?
A: The United Abrasives 38119 has an 18,000 RPM maximum operating speed and is sold in a box of 100 cartridge rolls. Check the mounting accessory separately before ordering.
