* Double row annular contact spindle bearings: provide superior accuracy
* Four different style threads: inch, metric, module, diametral - do it all!
* Hardened & ground bed ways: premium English Meehanite casting - the best
* Tag-along tailstock: facilitates power boring and positioning tailstock
* 4-way power rapid traverse: saves operators' time and energy
* One-handle power operation of carriage & cross slide: safe & easy
* Pressurized headstock lubrication: forces plenty of oil to critical areas
