The best way to use is predrill 1/2 Forster bit, then use the marble drilling bit to finish hole. This allows to be able to drill more holes without the marble bit filling up with saw dust.
Set your drill press to about 3/16 “
Then drill with marble bit!

I like the marble drill bit very much. It works well right out of the package but is adjustable for greater depth if necessary.

Saves so much timee
Aside from having to clean the sawdust out after every three or four holes, this bit made my project fly. There is almost no other way I could have kept the holes the right size without this.. Pro tip, drill until the spring is collapsed but stop when you see the bottom collar start to turn. It will leave an extra circle around the edge if you let it spin too long.

Making a marble game and need smooth holes
Richard S on Jan 24, 2020
My other one is wearing out. 2 things: I am going to replace the plastic ring on it with a steel one. It gets too hot and melts making the whole thing not usable until cleaned out. Also the 1/32" thick guide-end at the end of the bit got too hot and ended up bending/ ultimately breaking off.<br />Hope these issues can be fixed. This is already a great product with no parallels on the market, but its just a start. I'de love a 3/4" version eventually too. Might just make my own.

I want to drill holes/divots for an aggravation board game I’m making that uses 18mm marbles. I’m not clear what size holes the marble drilling bit creates. Are they 1/2” diameter?
CLeeB on Nov 22, 2019
What size marbles sit comfortably in the indentation?
Marc B on Nov 25, 2015
BEST ANSWER: Marbles should be 9/16" diameter. The same marbles that are used for Chinese checkers.
? what would the templet hole size be for this marble drilling bit
Robert C on May 31, 2016
Is it for a drill press or router ?
A shopper on Apr 24, 2015
BEST ANSWER: I use mine mounted in a drill press and also have used it with a hand held drill, using a template to guide the bit. I am not aware of hex shank bits being used in a router. Also, the router RPM may be excessive for this bit. One would need to consult with the bit Manufacturer.
can i use this on my template even though the holes are 3/4 inches?
Scott D on Jan 23, 2016
BEST ANSWER: Not likely.
You would have to come up with some kind of a bushing to go from 9/16"-3/4". Perhaps you could get a .75" OD bushing with a .5675" ID opening and remake your template?
Does the spring loaded sleeve press down with enough pressure to keep the wood from splintering around the hole as the hole is drilled?
mr glenn on Nov 15, 2015
BEST ANSWER: I think it depends on the wood species. I'm drilling in cherry and the rounded bottom of the hole is okay, but there is a bit of fuzz around the perimeter of each hole and I use my orbital sander to clean that up.

The one problem I have is that the spring loaded sleeve clogs up with saw dust, so I
clean it out with a short (and sharpened) eighth-inch brass rod after each hole is drilled. Maybe this is the reason I don't have splintering. It takes two hours to drill one chinese checker board, but the result is really good.

Also, I plan on rounding the end of a wooden dowel and gluing small strips of 220-grit sandpaper to polish the interior of each hole - ah, what we do to achieve perfection!
Drifting? I bought a circular piece of wood (24" across, common pine) to make a Wahoo board. But the wood is so soft that if you look at it wrong, you'll dent it. I drew out my circles on the board and started, the first 3 of 4 holes I did I messed up because the bit would drift until it bit into the board. I even tried putting my weight into but it didn't help. I am using a battery powered handheld drill.

Have any suggestions to stop the drifting? Lower RPMs? An attachment? I don't have a drill press.

What if I made a template from another board, drilled out all of my holes (all the way through the board and just wide enough for my marble drilling bit to fit through) and clamped it to my project?

Thank you for any suggestions you may have!!
Marc B on Dec 7, 2015
BEST ANSWER: I'm familiar with the game you reference but pine might not be the best choice. It is very soft and tends to dent very easily in regular use. I would oak, maple, or walnut. I produced a game board using walnut which looks pretty good. The trick to using the marble cutting tool is to first build a template of the game board you are trying to reproduce. I used eighth inch hardboard. I put masking tape on the template wood first so I could easily see where to drill the holes. I used a punch to make an indentation in the template first so that the tip on the forstener bit was exactly in line with the game pattern. Make sure the template hole matches the flange on the marble drilling bit. As you know Rocklet has templates for some game boards if they will work for you. It is worth the time to build the template first and that allows your finished product to be something that you will be happy with. Good luck.
I recently got my bit and today tried using it on an Edge-Glued Round board from Home Depot.

But the wood is so soft (if you look at it wrong, you'll dent it), that using my handheld drill, I have trouble with the bit drifting and then I end up with an indentation where I don't want one. I messed up three out of the four holes that I tried, so I stopped to get some advice here. I was even putting my weight into the drill so that it wouldn't drift but it still did.

I tested it a week or so ago on another board (pine too probably but harder I guess) and of the 10 or so holes I made, it only drifted on me once.

Anyone have any suggestions please??

Thank you!!!
Marc B on Dec 6, 2015
BEST ANSWER: Are you using a template? I used a template made out of masonite and had no problem.
Is it necessary, or even possible to sharpen this Marble Drilling Bit
Thomas F on Mar 3, 2016
BEST ANSWER: I do not know but I have drilled over 1000 holes in ash, cherry. Walnut, red and white oak and Birdseye maple and it still cuts clean.
What size Forster bit to use for making the template?
Frank M on Nov 3, 2015
BEST ANSWER: I used a 9/16 forstner bit to make my template
Two questions. What thickness template is this bit for? And, what is the diameter of the "collet"? In other words, what are the dimensions of the "step" on the bit guide?
A shopper on Aug 13, 2015
BEST ANSWER: 1/8 inch
so do I simply use a power drill with the with the marble drilling bit and it will create a hole for a marble? or do i need to start the hole first with a forstner bit?
Cameron M on Mar 28, 2019
BEST ANSWER: Hello Cameron. You use the bit just like a regular bit. No need to pre drill. The bit has a plunge spring on it, so it does take a steady hand. It can also be used in a drill press to ensure 100% steadiness. Hope this answers your question.
What is the set screw for on the side of the marble drilling bit #41463? I'm assuming depth adjustment. Is there any point using it?
David on Dec 20, 2018
BEST ANSWER: The screw is NOT a depth setting device. It allows the drilling head to be disassembled. The hex shaft is connected to the paddle drill by the collar that contains the set screw. That screw holds the paddle drill in the collar. Unless you are using a template the drill works best if you remove the spring and cylinder a from the drill. Without a template the cylinder will leave a circular mark on your work piece, since it rotates with the drill. Removing that set screw allows you to disassemble and re-assemble the drill as needed.
What is the diameter of the hole/dimple the 41463 - Marble Drilling Bit makes? How deep?
Orin B on Oct 16, 2017
BEST ANSWER: The depth is adjustable. The pattern hole is 9/16 so I'm guessing a little smaller about 1/2 inch for the dimples.
