*'''Swivel Head''' (to allow angled cuts)

Notes: The swivel clamp fastener should be mounted such that the swivel plate is horizontally clamped to the base disc. If the fastener is vertically mounted, then clamping the swivel head can cause bending that reduces the precision of the Cold Saw.
 
=Feature: Adjustable and Removable Vise Jaws=
 
*'''Adjustable and Removable Vise Jaws''' (to accommodate variety of workpiece shapes and dimensions)

=Feature: Fixed Blade Guard=
 
*'''Fixed Blade Guard''' (to protect against unintended blade contact during operation)

=Feature: Forward and Backward Drive Stops=
 
*'''Forward and Backward Drive Stops''' (to prevent cutting into vise and to hold blade in mid-air while mounting the workpiece)
