It should be the same taper, and if you can lengthen the drawbar it should be good, although I seem to remember someplace had a "pullstud" with female threads in it that fit in the NMTB spindles, put it may require shortening the drawbar a tad.. You may have to remove 1 drive lug for proper alingment. If this is the case you may want to add a modified lug to where you removed the one so as to keep the spindle balanced yet, but not to engage the toolholder.

OK thanks Jeff . I wandered if the solid holders where a running fit or just a little loose . I may go scrounging tomorrow see what I find . Maybe get lucky and find what I need I'm getting antsy to get this baby making chips and not being a 3 ton shelf

Steve,
Any end mill over 5/16s I would use in a solid holder. Anything smaller can be held in a collet holder. This is the primary way do things where I work. Just be careful that you get holder that are rated for the higher rpms that the smaller end mills can br used at. One of the CNC mills where I work goes over 20,000 rpm but they only have holders rated to 18,000 rpm so they stop programming there. Still is scarey running tooling at that rpm! You never hear anything wrong until it is too late Most of the time you do know anything is wrong until the program ends and you get to look at the part. Then you start replacing tools and try to save the part.

18,000 rpm I don't have to worry about that my mill will only get 4200 max . I was thinking that on the tool holder but only going to 1/4" on the collet . It'll be awhile till I get a VMC , I'll prob. have a manuel BP before that for that 1 time job unless there's angles and radi in it .
