Bit to enlarge draft hole?

Is this what I want to ream out a draft hole on an "estate" pipe? http://www.amazon.com/Irwin-Tools-4...f=sr_1_29?s=hi&ie=UTF8&qid=1329842186&sr=1-29

If not, what?

Thankee.

That might be a tad small. I use 9/64" to drill airways. You might need to start small and then move up depending on condition.

That would probably work but it's entirely unnecessary to use a carbide tipped drill bit for pipe work. An ordinary drill bit, or better yet a pipe-repair kit (you can get these from eBay or any number of pipe vendors) will work fine.

If you are just reaming, then the tool I posted is a good bet - if you are looking to actually remove wood and enlarge it, then a regular twist drill bit without carbide tips is what you want, at whatever size you like (5/32" being pretty standard)

The "Senior Pipe Reamer" has one built in I believe. Get one of those and you'll have your bowl reamer as well. The draft hole reamer on this model has a grip on the end of it. I suspect if you chuck that bit up to a drill, it may break the pipe somehow or chunk it across the room. If you do it using this bit I would suggest using the drill in reverse.

SAS! Youre ninja skills are fast!! We typed at the same time!

Are you talking about cleaning or enlarging? Shank or stem?

Hi all!
I use a 3/16" bit to enlarge the draught hole. The smoking qualities of ALL my pipes have improved drastically!
It's especially handy for work on some Estates as some of them look as if they've never been cleaned!

Enlarge shank.

Buy the bit, go in reverse. Its not if it catches, its when...

I have a set of 'number' drills for my model engineering and precision work, they increase diameter by steps of just a few thousandths of an inch, an are very handy for opening up airways. One that is a 'snug' fit can be used as a starting point - then gradually increase.....I just grip the shank in the vise (alloy 'soft jaws' in place!) and rotate the pipe onto it by hand - never by power drill!
OT

You know us yanks dont have the patience for that!!

A young guy I worked with once ran a drill into his pipe by his Black&Decker - he's got a neat little 4mm hole in the far side of the bowl, to store pipe mud in!

I use a Senior Reamer and it works great. It will remove wood if pressed and is the perfect diameter for getting a nice open airway--it's also 9cm long.
