I’m looking to drill my 150 gallon tank and am considering doing it myself. BRS recommend using a drill press attachment. They have one for sale on their site for $54.99.

Drill Press Attachment for Hand Drills
Why does BRS recommend this? If you have never drilled glass before it can be a bit daunting. To make it easier we highly recommend a drill press to keep your drill from jumping around and allowing you to have nice smooth control of the drill bit. These presses will work for many other...www.bulkreefsupply.com
I took a look on Amazon and found what I believe is the same product for about $30.
Could somebody confirm that these are the same product?
Much appreciated,
David

Thanks for confirming that their the same product. I understand that you guys simply don’t get the product mass of power tool equipment to offer the best price. I appreciate the convenience that BRS offers to their customers and to the reefing hobby in general.Hi @DavidJTawil,
Thanks for the question. From what I can tell by Amazon's description, these do appear to be the same item. A couple of things to note. When it comes to power tools and power tool accessories, we're simply not able to compete with retailers like Amazon, Home Depot, Lowe's, etc on price. We don't sell a whole lot of these, so we don't get the bulk pricing that the major retailers likely get. This is mainly offered as a convenience item to help reefers with their project. At the end of the day, our pricing is based on what we buy the product for + a little bit of profit.
I believe he's referring to this BRStv Investigates video HERE.

BRSTV is the best thing that happened to this hobby.I believe he's referring to this BRStv Investigates video HERE.
Well, since you’ve drilled hundreds, may I pick your brain a bit?Unless it's a dedicated portable core drill press (VERY expensive), I have found that they just don't do any better than a template and holding the drill in your hand.
I have drilled hundreds of tanks and only broken two and shouldn't have attempted either to begin with.![]()
Yup. Too lazy to go look for itI believe he's referring to this BRStv Investigates video HERE.

When I drill the new tank I’ll be using a template plus a guide. The guide is just to keep things level. My garage floor has a slope to it. I made some custom templates for the custom Modular Marine over flow. The templates had to be within 3mm to conceal the water line when pumps are off. Now my question is since you’ve drilled many tanks is. Would you drill from both sides? I know that is the right way to do it, but alignment is critical when doing it this way. I did make two templates. One for the outside and one for the inside as the templates are different heights due to the tank frame. The holes do line up though when placing both the outside and inside templates on the glass at the same time. Some glass manufacturers drill from both sides at the same time. But that’s with a dedicated machine to do that. Also would you recommend taping the backside and using a backer board of some sort? Clamped to the glass to help with chipping? Water or Oil based lubricant. Last tank I drilled with sunflower oil I believe. I had very little chipping. Just let the drill do the work with very little pressure. Water seems to be the most popular, but I wonder if one would give you a better cut. I see vegetable oil as an aquarium safe option also.

I don’t think I’m brave enough to drill from both sides anyways. Just for the reasons above. Thanks for the feedback.Plain water is all you need and definitely don't drill from both sides. It's almost impossible to line up and has a greater risk of catching and breaking the glass.
