3/16 x 1 x 1/4 (3" 全長) 卡式心軸 B-1

The 3/16 shank fits my die grinder perfectly and the 1/4 inch roll width lines up with the cartridge rolls I already had. Been using it on welds for a couple weeks and it hasn't wobbled or bent yet.

Snapped right into my rotary tool and the 1/4 inch roll width held the cartridge rolls tight with zero wobble. Used it to deburr some aluminum plate and the 3 inch overall length gave me just enough reach without flexing. Wish I'd picked one up sooner.
