Eastwood 20438 MIG175 Replacement Knurled Drive Roller for Flux Core Wire Feed

The Eastwood 20438 Knurled Drive Roller is a direct replacement drive roller designed specifically for the Eastwood MIG 175 welder. The knurled surface provides superior grip on welding wire, delivering a smooth and consistent wire feed—especially critical when running flux core wire applications.

Key Features:

• Knurled surface for reliable wire grip and consistent feed performance
• Two wire size grooves: one groove for 0.023 in. (0.6 mm) wire, and one groove for 0.030–0.035 in. (0.8–0.9 mm) wire
• Compatible with both solid and flux core welding wire
• Keyway-style mount for secure, precise installation
• Outside Diameter: 30 mm | Inside Diameter: 10 mm | Width: 10 mm

This knurled drive roller is the recommended choice over a standard roller when regularly running flux core wire, as the knurled teeth grip the softer wire without slipping. The roller ships as a single replacement unit and features a keyway-style mount compatible with the MIG 175's drive motor housing.
