Hi Rob
For parallel iron shafts I would recommend you buy 0.373 and not 0.375 inch.
I find this works best for over 90% of the shafts and then the fit isn't
sloppy.
I run my drill press at 195 rpm, but I think RK has suggested even 150 - 200
rpm.
A lot of drill presses have 250 as their lowest speed so that is what most
people use.
When I reshaft GBB's I ream the bore-through when reshafting with steel
shaft.
The bottom portion of the bore-through is smaller dia than the hosel top
portion.
When you try to install a steel shaft it goes maybe 3/4 of the way down then
stops.
Since there is no hosel to clamp to I just use a battery 3/8 drill with wood
reamer.
Go through real slow and when you get near the tight fit it will go through
like butter.
Don't always have to use a drill press. I would never use a drill bit +
hand as a vise.
I agree with TFlan, for woods use the Letter R (0.339 inch) reamer.
I asked RK once if I should buy straight flute or right hand flute.
He said buy right hand flute as first option, straight as 2nd option, but
never left hand.
The reamers are very inexpensive at Wholesale Tool. Stock up on the 0.373
and 0.339 inch.
Thanks HarryS (Golf54.com)

I'll add my $.02 in agreement. Using drill bits can be dangerous because of
the tendency of the bit to grab and snap suddenly, even at low speeds. If
the heads are stainless steel, the problem is even worse because stainless
has a tendency to "gall" instead of cutting smoothly with a drill bit. What
happens is that the friction between the bit and the steel head causes
minute welds between the two steels. As long as the bit is moving, the
welds shear off and you tend to see a buildup of material on the walls of
the hole or the bit. At some point, the "weld" doesn't shear and you get
really strong impact loading on the bit, and it can literally shatter.
Drill bits are designed to remove material from the leading edge of the
cutter which is active only at the end, and has only two cutting surfaces
that remove material along two radial lines from the center of the bit out
to the tip of each flute. They are not designed to remove material using
only the tips of the flutes. The flutes are designed to lift the cuttings
out of the hole, and although they may seem sharp, they are not designed as
cutting surfaces.
A reamer has multiple axial cutting surfaces along the length of the bit,
and is designed to remove material from the sidewalls of the hole rather
than the bottom of the hole. The cutting edges are well supported by the
base material of the reamer, and really look like small saw teeth in cross
section. So.even though it looks like a reamer takes a much smaller
"bite" from the hole, it actually turns out to be a whole lot more efficient
at turning a tapered hosel into a parallel hosel. Be sure to use a good
cutting oil...which cools the metal a bit and also helps carry the cuttings
away from the point of the cut.
I use a reamer to also clean out the hosel on a reshaftit will cut only
to the size of the reamer, and doesn't "wander" like a drill bit can. If
you are drilling out old epoxy, and the bit suddenly hits the steel wall of
the hosel, you can also get the impact loading that will snap a drill bit.
The key is to keep in mind where the cutting surface is on the tool and what
it is intended to cut.
Probably more than you ever wanted to know about reamers vs. drill bits, but
that's what you get when you ask an engineer a question

You can find lettered, fractional, decimal, and metric reamers at Wholesale
Tool, and at most of the larger tool supply houses. Use letter "R" (.339")
for woods, 3/8" for irons. Golfsmith sells them, as does B & M. What RK
explains essentially is this: Don't use drill bits to enlarge taper tip
hosels because of the likelihood of the bit hanging up in the hosel. Use the
appropriate size reamer and a good quality cutting oil such as "Tap Magic."
Clamp the hosel in a drillpress vise and adjust your drill press to the
lowest speed possible - 250 rpm or so. Low rpms, heavy feed, and good
cutting lubricant on a good cutting tool should do the job.
That's the way I do it and I'm pretty sure that's what RK said. If I'm
incorrect no doubt he'll let me know in no uncertain terms ;-)
