1st post and I’m already needy …

I am interested in the Grizzly G7944 drill press and I’m looking for the opinion of others. I am both a wood and metal worker so my requirements are for a reasonably priced and accurate drill press with low spindle speed for using larger drill bit in metal.

$435 delivered seems reasonable, although I do worry about post-sales problems. For example, what if the spindle has an unacceptable runout and how would I get the issue resolved.

I’ve looked for comparable products from Steel City, Ridgid, Delta and others and I’ve not found one with a low spindle speed of 150RPM. I think the low spindle speed requirement is met here.

My information seeking is around the quality and accuracy of the tool. Any opinions welcomed.

-Steve

I own this unit:

It only goes down to 300 RPM, but it has all the features the Grizzly does, and is about $100 less money. I have no problems with it and the runout is great. I did put a florescent white-light bulb in the light.
I don’t know why you need the 150 RPM, but if that is a strong thing for you, then I guess the Grizz is it.

I used to have the G7943 (same press, but benchtop version).
It’s a good press, but I don’t think I’d pay that much for it.
You can get the porter cable 15” press from lowe’s for about $300, and it’s a better press IMHO (longer quill travel, bigger swing, nicer light).

I also have the PC drill press and would recommend it to anyone. Get yourself a movers discount coupon and you can get it for about $270. No expensive shipping charges either. Sucker is heavy though, Easiest way to assemble is is lay it on it’s side, and slide the head on, than raise it upright. Don’t follow instructions and try to pick that sucker up unless you have a gaggle of trained gorillas at your beck and call.

I appreciate your opinions and I agonized over the Grizzly and Porter Cable machines, even went to Lowes to look at the Porter Cable. If I was using it just for wood I would definitely have purchased the Porter Cable press, but the 300RPM low speed is just too fast for larger drill bits into thicker steel so I ordered the Grizzly. I’ll write up a review when I get it set up.

Thank you, Gentlemen!

If drilling mild steel with a surface speed of about 100 [surface ft/min] you could use up to about a 1.25” drill in the PC. Here’s the formula I always used when cutting with Reg. High Speed Steel cutting tools before retiring as a Journeyman Machinist:
RPM = (sfpm x 3.82) รท part or cutter diameter

Here’s a good little chart:

Just hope you don’t need to drill anything like Nitronic 50 ;-)

That’s interesting information, thank you. The Grizz will be here on Monday so I’ll know if I made a mistake.
