Features
Professional “Quarter-Scale”
Precisely mill 2” or 1” lumber thanks to the same kind of professional depth-of-cut scale you’d find on band sawmills. The 5/16th kerf is already calculated in.
Sawbar and Chain Guard
Helps guard sawbars up to 20” long.
Track Sweepers
Built-in track sweepers next to each carriage wheel remove sawdust and debris from the track for smooth rolling action.
Endstops
Safety feature helps prevent run-off of saw carriage.
Smooth Sawhead Action
Smooth operation of the sawhead crank handle precisely adjusts the sawhead height - Clockwise to raise the sawhead, counter-clockwise to lower the sawhead. Once you’ve set the sawhead height, the locking handle securely locks it in place.
Operator Comfort

Patented Throttle Actuator
Actuator connects the chainsaw’s throttle to a convenient handle-mounted throttle control – permits easy activation of the chainsaw throttle at the push handle. Patented mechanism fits all chainsaws.
Adjustable Outrigger Arm

Optional Equipment
 | Auxiliary Chain & Bar Oiler Chainsaws only deliver oil to the top of the bar where it is easily thrown off at the nose, especially when mounted sideways for milling. The auxiliary PortaMill Oiler Kit delivers oil to the sprocket of the chainsaw bar to reduce friction and chain heat. Kit includes bottle, bottle basket, oil line with valve and copper nozzle. (Item No. PM02) |
 | Additional Log Clamping/Bunk Units The PortaMill comes equipped standard with two log rest/log dog assemblies for fast dogging and positive locking. For longer milling on extended ladders and for extra log support, additional log clamping/bunk kits are available. Kit includes one log rest/log dog assembly. (Item No. PM14-BUNKKIT) |
