Deep Splines for FULL Depth Engagement of Bottom Bracket Splines. I leaned on this puppy with a 1/2" Breaker bar and almost all of my weight. The Bottom Bracket was completely seized, so it sheared off all of the splines completely smooth on one side with ZERO Damage or distortion of the tool. With some penetrant and some heat I did successfully remove the other cup with this tool, once again with the Half Inch Drive Breaker Bar and all of my weight leaning on it. Then of course, drill city to remove the damaged side. Lotsa Fun! I first tried another major brand bottom bracket tool on this bottom bracket, but I couldn't get it to sit square under torque. The tool splines were not deep enough to fully engage the cup splines.
