Product Description

1.5THCP Series Center Punch

Put a punch mark directly below your SMR location

The 1.5THCP magnetic adapter is an SMR nest which doubles as a transfer punch locator, allowing you to mark a point directly under the SMR. The magnet in the 1.5THCP is positioned to create a somewhat stronger bond on the bottom than on the top. This offset-magnet approach helps to hold the adapter in place while the SMR is removed and the transfer punch is inserted through the precision center hole. The center hole is true to the center of the SMR within ±0.001″ (±0.026mm). An optical alley is provided to allow negative viewing angles, and step edges allow for a better grip. The transfer punch is included.
