All our Uni-Throaters, Uni-Neckers, and Uni-Throater/Neckers are sold with a Sliding Bushing. This Bushing centers the tool in the chamber and controls depth of cut by bottoming on the chamber shoulder. Sold separately, this Bushing can replace a lost or damaged Bushing. Be sure to specify a caliber when ordering a replacement Bushing.

The standard shoulder contact angle on the Sliding Bushing is 30 degrees. The Bushing will stop HIGH on lesser shoulder angles (e.g. .270 Winchester), and stop LOW on greater shoulder angles (e.g. 40-degree Ackley Improved). Usually, this limited shoulder contact is adequate to ensure repeatable operations. Pacific Tool and Gauge will manufacture a Bushing with a custom shoulder angle, for $85. Please contact a sales associate if you require a Sliding Bushing with a custom shoulder angle.


NOTE: All PTG Reamers and Cutting Tools are designed to work with petroleum-based lubricant. Water-based lubricant can give acceptable results, however the life of the tool will be reduced. For best results use petroleum-based lubricant.
