Inherently centered from the topslide, these tools allow boring to be started from just a 1/4" drilled hole. Tension, induced by the pushrod, makes even the smallest tool surprisingly rigid.
There are two boring bars of each size, Ø1/4", Ø5/16" and Ø3/8" - One bar for boring & facing, the other for internal screw cutting & recessing. The kit includes 3 iron castings for the tool blocks, steel, fasteners, HSS drill blanks, long series drill (needed to machine the boring bars) drawings and instructions.
Whilst the castings and design have been developed for Myford 7 Series lathes, captive raising blocks or Quick-Change geometry will make these tools suitable for virtually all lathes.
