When removing machining burrs, rough edges, and excess material from wider internal openings, the United Abrasives 38126 Straight Cartridge Roll provides effective abrasive cutting action across a broad cylindrical working surface. Featuring a 1" diameter, 1-1/2" length, and 60-grit premium aluminum oxide abrasive, this cartridge roll supports coarse-to-intermediate sanding, deburring, flash removal, and surface preparation on metal components. Its straight configuration allows operators to work along channels, fillets, internal side walls, recesses, and the bottoms of dead-end holes where conventional grinding discs may be difficult to position. The 1" diameter provides greater abrasive contact area than smaller cartridge rolls when the workpiece offers sufficient clearance, making it particularly useful for sanding larger recessed surfaces. United Abrasives identifies ferrous metals, non-ferrous metals, stainless steel, and high-tensile steel as suitable workpiece materials.
The United Abrasives 38126 incorporates a multi-layer, self-dressing construction, which exposes fresh cutting abrasive as successive layers wear away, helping maintain effective sanding action during use. Its 1/4" arbor opening corresponds to the manufacturer-specified 95102 cartridge roll mandrel for mounting on compatible rotary tools. This larger arbor configuration differs from the 3/16" openings used on certain smaller cartridge rolls, making mandrel selection an important purchasing consideration. The 18,000 maximum RPM rating establishes the abrasive's upper operating speed limit and must be matched to the tool and mounting accessory. Supplied in a box of 100, the 38126 supports recurring deburring and surface preparation requirements in machining facilities, fabrication shops, toolrooms, and industrial maintenance departments.

- Supplied in boxes of 100 for consistent abrasive stocking and replenishment in machining, fabrication, and maintenance environments.
Applications:
- Machining and CNC workshops - Removing machining burrs, blending rough tool marks, and smoothing wider internal grooves on machined metal components.
- Metal fabrication and welding - Cleaning up localized flash, reducing rough edges, and preparing recessed metal surfaces for subsequent abrasive finishing.
- Tool and die manufacturing - Sanding accessible tooling cavities, internal fillets, and wider recessed contours where the larger cartridge roll diameter provides useful contact.
- Stainless steel and alloy steel processing - Performing localized deburring and initial surface preparation on stainless steel and high-tensile steel components.
- Industrial maintenance and equipment repair - Removing surface irregularities and preparing accessible metal fittings, machinery parts, and recessed repair areas for additional finishing.
FAQs:
- Q: What is the United Abrasives 38126 Straight Cartridge Roll used for?
A: The 38126 is used for sanding, deburring, flash removal, and surface preparation on metal components. Its 1" diameter offers broader contact for accessible internal surfaces, while the 60-grit abrasive provides the cutting action needed to remove burrs and rough machining marks before finer finishing. - Q: What is the difference between United Abrasives 38126 and 38127 cartridge rolls?
A: Both models feature a 1" diameter, 1-1/2" length, 1/4" arbor opening, and 18,000 RPM maximum operating speed. The 38126 uses 60-grit aluminum oxide abrasive for greater material removal, while the 38127 features finer 80-grit abrasive for intermediate sanding and surface refinement. - Q: When should I choose a 1" diameter cartridge roll instead of a 3/4" version?
A: The 1" diameter provides a larger abrasive working surface for wider grooves and accessible cavities. A smaller 3/4" or 1/2" roll may be preferable when opening size or internal clearance prevents the larger abrasive from fitting properly. - Q: Can the United Abrasives 38126 be used on stainless steel?
A: Yes. United Abrasives lists stainless steel and high-tensile steel among the suitable materials, along with ferrous and non-ferrous metals. For applications where surface contamination is a concern, use cartridge rolls dedicated to stainless steel rather than abrasives previously used on carbon steel. - Q: Which mandrel is recommended for United Abrasives part number 38126?
A: The United Abrasives 2025-2026 catalog identifies mandrel part number 95102 for this cartridge roll. The 38126 has a 1/4" arbor opening, so mandrels intended for 1/8" or 3/16" openings are not the correct dimensional match. Verify proper mounting engagement, secure installation, and rotary tool compatibility before use. - Q: How many cartridge rolls are supplied, and what is their maximum operating speed?
A: United Abrasives part number 38126 is sold in a box of 100 cartridge rolls, each with a maximum operating speed of 18,000 RPM. The rotary tool's maximum speed must not exceed this rating, and the mandrel must also be suitable for the intended operating conditions.
