12C401 - Walter Type 17 Grinding Cone 1.5x3 Inch ZA16 Coarse

Aggressive Grinding for Hard-to-Reach Welds

When your angle grinder or flap disc just can't fit into that tight corner or pipe interior, the Walter 12C401 Plug Cone #17 is the solution you need. Built for professional welders who demand speed and aggression, this grinding cone features a coarse 16-grit Zirconia Alumina (ZA) formula that eats through metal fast. It is specifically designed to tackle the toughest grinding jobs on steel and stainless steel without bogging down or glazing over.

The Type 17 shape (flat-tipped cone) is perfect for getting into 90-degree corners, grinding out fillet welds, or smoothing the inside of pipes and holes. With a substantial size of 1-1/2" x 3", it offers plenty of abrasive surface area to last through heavy jobs. The internal threaded arbor means you can spin this cone directly onto your grinder's spindle—no fiddling with collets or chucks required. This secure connection ensures the cone runs true, giving you better control and less vibration, which is critical when you're grinding in awkward positions.

Don't waste time with underpowered abrasives when you have heavy slag or excess weld metal to remove. The Walter ZA16 grain fractures as it cuts, constantly revealing sharp new cutting edges. This self-sharpening action keeps the cone cutting cool and fast, preventing heat buildup that could warp your workpiece. Whether you are prepping a joint for a critical weld or cleaning up a messy repair, this plug cone gives you the power to finish the job quickly and move on to the next one.
