Micrometer Seating Die

Regular price $189.00 $0.00

Our new micrometer seating die has an in-line 316 stainless steel stem with a conical bullet seat for accuracy and repeatability. All stems have a 0.0002” clearance for alignment and 0.500” adjustment for seating depth. Comes ready to ream in 17 to 30 caliber. The large easy to read micrometer head has position set locking. The left set screw can be adjusted to create friction on the micrometer spindle so the setting cannot be easily moved. The set screw on the right locks the spindle. The super precision Mitutoyo micrometer head has a 0.0001” accuracy guarantee.
