Tip Trimming and Determining Bore Type      
  Our catalog defines all of our models as to bore type. But what if you are working with a non-Hireko head? How is bore type determined? It's really very simple. Take a shaft and measure its length. Let's say it measures 45" for example. Put the shaft in the hosel of the club into which it will be installed. Measure the length of the club with this shaft test fitted into it. If it is 45 1/2", it is a blind bore. A measurement of 46" indicates an M2; a measure of 46 1/2" shows that the head is an M1. That's all there is to it. Then simply follow the trimming instructions found in the catalog for proper shaft trimming.

But what if the measure is not exactly as stated above? Let's say you get 46 1/4". Simply adjust the trimming accordingly. This measure is between an M1 and M2. You can look at the M1 trimming and then trim 1/4" less than the instructions specify or you can look at the club as an M2 and trim 1/4" more. It's that easy!
