You'll need to know the Morse Taper size of your tailstock. Most likely a MT2 or a MT1.

(clip) ^^^^^^^^^^^^^ That's probably the best answer, but there are two other ways you can go. Knowing the Morse taper number for yo9ur tailstock, you can get drill bits with that taper on the shank. The main advantage is that they use up less of the space between the spindle and tailstock, which could matter if you are drilling into the end of a long spindle. It is also possible to buy collets with a Morse taper to fit your lathe, on the outside, and a bore to fit a certain drill diameter on the inside. This has the advantage that you can use a drillset you already have.
What do you call the bits with the MT shank and where might we find them? I can see that using such bits would be advantageous if you had a lot of same size drilling to do. Also less margin for error.
usually listed as 'Morse Taper drill bits' or maybe 'Morse Taper shank'... available from most any Industrial Supply such as MSC, J&L, McMaster Carr, etc - Travers Tool used to have best prices but it's been awhikle scince I checked them
BTW th MT shank drills are relatively pricey

Thanks. Did some searching and checked prices. OUCH! Think I'll stick with the jacobs chuck for now.
And how !!! I needed a 22mm #2MT drill bit for use in making an implement for my tractor.
Good quality (Dormer, I think - it is at #1 son's house now)
$50 Oz
Hell, I bought about 40 used ones in 6 sizes to 20mm at an auction for $15, just needed sharpening, although some were well worn with sharpening. Alan in beautiful Golden Bay, Western Oz, South 32.25.42, East 115.45.44 GMT+8 VK6 YAB ICQ 6581610 to reply, change oz to au in address
