Boring deep holes

Who makes a 1/4" bit long enough to bore 2" deep dog holes? Anybody have deflection issues at that depth?

I can’t remember the brand or supplier of my extra long 1/4" upcut end mill, but I’ve made several 2" deep carves with no trouble.

www.bitsbits.com has extra long bits that I’m using without issue. See Extra Long CNC Bits | BitsBits.com for their list.

Of course bitsbits has what I need, Should’ve started there. Thank you.

I purchased a number of end mills from Lakeshore Carbide https://www.lakeshorecarbide.com. Great prices and support. I use their aluminum end mills for both aluminum and wood. If you need more exotic tools, Harvey Tools https://www.harveytool.com has some great specialty tools and very small tools eg lollipop cutters and reverse chamfer mills so that you can complete a part from a single side (with appropriate work holding)…their smallest diameter end mill is 0.0015”/37 microns! (Some are great if you want to do some fine metal engraving/relief work in brass for instance)

Cheers

Al
