Drilling blank question

[jd99]

I was wondering if anyone has ever tried drilling their blanks with a gun drill (it would have to be on a lathe naturaly)?

I've drilled tens of thousand of holes in a gamit of metals with gun drills they don't get chip bound due to the straight flute, cut straight (stronger) I was just wondering if they would work for driling blanks, you could drill the complete length of the blank then cut it instead of cutting in two then drilling.

Just pondering. :biggrin: slow day at work.

Good thought, but some pen blanks take 2 different sizes of drills.

I have use those or similar for drilling long distances -- a bit spendy for routine use - I got mine used a Boeing Surplus and got to refurbish them for wood work.

Should work fine -

(Memory is that bag pipe makers use those and "d-drills" for the long holes)

I never ever heard of them. Learn something everyday on here.

What about the oil flush? if you run dry, I don't see those straight flutes evacuating well in wood. I've been wrong before though :biggrin:
I'm familiar with them from mold work, btw.

I have used them with compressed air -- somthing of a hassle to rig up -- but they do drill straight --

More hassle than makes sense to me for pens -- but for long barley twists, works well.
