Criterion Boring Head Arbors by Sherline

Introducing the Sherline/Criterion Boring Head Arbors, designed in collaboration with customer Wayne Neilson for use with the Criterion S-1-1/2 boring head on our Sherline milling machines. The Criterion boring head, manufactured in the USA, is renowned for its durability and precision, making it an ideal match for our machines. The Morse #1 to 7/8-20 Criterion Boring Head (P/N 12131) fits directly into the Morse #1 taper on our standard headstock spindle, complete with an included 1/4-20 x 5 drawbolt and washer. The End Mill Holder to 7/8-20 Criterion Boring Head (P/N 12141) threads onto our -16 Morse #1 spindle thread, accompanied by a Tommy bar. Select the arbor or holder that suits your needs, attach your Criterion S-1-1/2 boring head, and commence boring flawless holes.
