For those of you who might have missed out on the last group buy of the step bit used for the Pentel pencil conversion, or if you are looking for an additional bit or two... I found the following source for the bit and wanted to share it with you.
http://www.wlfuller.com/html/hss_step_drills.html
You can email wlfuller your specifications and they will send you a quote. The bits are special order, but they are very easy to work with. Turn-around time was ~ two weeks for me. To give you a feel for prices, a recent quote that I received had the following prices.
1-2 @ $25.50
3-5 @ $24.10
6-11@ $22.90
12-23@ $21.65
Here are the specs for the bit, in the format that wlfuller requires.
(A) countersink diameter 17/64
(B) pilot diameter 5/32
(C) pilot length 1/2 inch
(D) flute length "long" 3 7/8 inches
(E) overall length "long" 6 1/4 inches
(F) shank diameter same as countersink
(G) angle 135 degrees
(H) material high speed steel (HSS)
(I) length of shank standard
(J) style style 1
Here is a picture of my bit (ignore the sharpie mark on it).
I have been trading emails with Don (its_virgil) on this. He indicated there have been several people who have expressed interest in getting a bit. Maybe someone out there will do a group buy.
If the Pentel conversion is a new topic for you there is an good article on this general topic written by Don in the library.
