POWERHOUSE POW351504 4-Inch Porting Mandrel for 1/4-Inch Cartridge Rolls

The POWERHOUSE POW351504 Porting Mandrel is designed for use with 1/4-inch cartridge rolls in porting, grinding, deburring, and finishing applications. Its steel construction provides a dependable foundation for abrasive work, while the black oxide finish helps support durability during repeated shop and maintenance use. The mandrel’s compact profile is well suited for reaching contours, internal passages, and other areas where controlled material removal is required.
The 4-inch working length offers useful reach for automotive, fabrication, industrial, and general metalworking tasks. When paired with a compatible cartridge roll, this mandrel helps provide consistent abrasive support and improved control compared with using loose abrasive material alone. It is a practical replacement or addition for shops that regularly perform cylinder head porting, weld cleanup, edge blending, and surface preparation.
Designed for compatibility with suitable rotary tools and abrasive equipment, the POWERHOUSE POW351504 should be operated according to the tool and cartridge roll manufacturer’s recommendations. Verify the mandrel and abrasive accessory are properly secured before use, and select operating speeds appropriate for the application. This product is supplied individually and provides a reliable solution for professionals and serious DIY users who need a dedicated mandrel for 1/4-inch cartridge rolls.
