Product Description
The Straight Shaft Boring Head was designed for those who are using an ER-16 or 3C headstock. Our standard boring head (P/N 3054) has a #1 Morse tapered shaft and is held in the 3/4 x 16 headstock spindle with a drawbolt. The holder has a straight shaft and is held in the spindle using a 3/8″ collet.*
A boring head provides a means of accurately machining almost any size hole. It is also capable of machining stepped holes for seating bearings and internal grooves for lock rings. Boring tools cut like lathe boring tools with the difference being the tool moves rather than the work.
*NOTE: Sherline Products does not sell 3/8″ collets used with the ER-16 or 3C headstock spindles. Those are available through Hardinge Inc. or other tool supply sources.
What’s included:
The Sherline straight-shaft boring head comes with a hex key for making adjustments; however, the cutting tools are not included. The boring head is designed for use with standard 3/8″ (10mm) diameter shank boring tools. For best results, the length of the tools should be kept to a minimum. You will find that a short tool gives you less chatter and it will be easier to hold tolerances.
Sherline also offers a fly cutter with a straight shaft for use in an ER-16 or 3C headstock spindles.
