United Abrasives Straight Cartridge Roll | 38014 | 1/4" Diameter | 60 Grit | Sold by Box of 100

For cleaning up burrs and rough surfaces inside narrow, extended metal features, the United Abrasives 38014 Straight Cartridge Roll combines coarse abrasive cutting action with a longer cylindrical sanding surface. Featuring a 1/4" diameter, 1-1/2" length, and 60-grit premium aluminum oxide abrasive, this cartridge roll is suitable for removing machining marks, blending localized imperfections, and preparing metal surfaces for subsequent finishing. Its narrow diameter allows access to channels, recesses, fillets, and internal features, while the extended abrasive length provides additional contact area along side walls and elongated grooves. The coarse 60-grit abrasive supports initial material removal on ferrous metals, non-ferrous metals, stainless steel, and high-tensile steel.

The United Abrasives 38014 incorporates a multi-layer, self-dressing construction, meaning fresh cutting abrasive is exposed as successive outer layers wear away. This helps maintain abrasive effectiveness during deburring and sanding operations. Its 1/8" arbor opening accommodates an appropriately sized cartridge roll mandrel for use with a compatible die grinder or rotary tool. With a maximum operating speed of 26,000 RPM, the roll supports high-speed deburring and flash removal when operated within the manufacturer's rated limits. Compared with the shorter 1" United Abrasives 38007, the 38014 retains the same diameter and grit while providing an additional 1/2" of abrasive length for longer internal surfaces. Supplied in a box of 100, this configuration supports recurring metalworking and maintenance requirements.

FAQs:

• Q: How does the United Abrasives 38014 differ from the 38007 Straight Cartridge Roll?
  A: Both products feature a 1/4" diameter, 60-grit aluminum oxide abrasive, and 26,000 RPM maximum operating speed. The 38014 is 1-1/2" long, while the 38007 is 1" long. The longer 38014 offers additional abrasive contact length for sanding extended grooves and internal walls.
• Q: Is 60 grit suitable for final metal finishing?
  A: The 60-grit abrasive is primarily suited to coarse sanding, burr removal, and initial surface preparation. For a smoother finish, follow with finer grits such as 80, 120, or 240, depending on the required surface texture.
• Q: Can the 38014 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. Use abrasives dedicated to stainless steel when avoiding cross-contamination from carbon steel is important.
• Q: What mandrel is needed for the United Abrasives 38014?
  A: The cartridge roll has a 1/8" arbor opening and requires a compatible cartridge roll mandrel. United Abrasives offers mandrels with 1/8" mounting diameters, including part number 95103 with a 1-1/2" length. Confirm the recommended mandrel and appropriate mounting engagement for this specific roll before ordering.
• Q: How many cartridge rolls are supplied, and what is the maximum operating speed?
  A: United Abrasives part number 38014 is sold in a box of 100. Each cartridge roll has a maximum operating speed of 26,000 RPM. The selected power tool must not exceed the abrasive's rated speed.
