marble drilling bit
I looked for and used several countersink bits before purchasing this bit.This does a good job as for as uniformity of the depth and clean cut rounded hole. Great bit!

Woodworking Experience:
I used the bit in my hand held drill with a guide that I made from a thin piece of wood. It did the job.
I thought the bit was a little expensive but it did such a great job that it was well worth it. My grandchildren love the game I made for them. I know I will make a lot more games with this tool. Thanks.

It works!
It works! I had doubts about its effectiveness/consistency/durability, especially with a cordless hand drill...before I actually used it. But a couple hundred holes later... and I'm very satisfied.

I am using the bit in my drill press to make Wahoo boards. Yes the collar traps sawdust in it however it keeps the work space easier to see. I drill 3 holes before clearing the bit with the ring end of a combination wrench. Part of the joys of woodworking is the nuances of different wood types and the difference in hardness so with little practice and adjusting my press I have gotten great results. This is the only bit I've found that does this with a high quality finish.
It is much harder to get consistent results in a handheld drill, you definitely need a guide to keep the bit steady and prevent drift.

Glad I made this purchase, I would do it again without reservation.

Good bit
Works as advertised. Glad I read some reviews before the purchase. I drill a shallow hole with a forstner bit first, then follow with this bit. I set the drill press speed as slow as possible and it worked just fine in birch and pine. After drilling several holes I stop and push up on the sleeve of the bit to clear out the end of the bit.
At first I thought it was kind of expensive, but it was perfect for my project. I have drilled at least 200 holes so far and it still works fine.

Woodworking Experience:
While I think the bit is great, but it would have been nice to have had somewhat of a point on the end to keep it from moving at the start. A bench drill does not have a deep enough depth for all the holes necessary for the marbles game board that I made.

? what would the templet hole size be for this marble drilling bit
Robert C on May 31, 2016
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.
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: With 3/4 inch holes it will be hard to control the drill and you may get over size holes or off round. Stu Porter
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.
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
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 diameter is 1/2" and 1/2" deep.
