MoparWoman Jamie Posted June 28, 2011 Posted June 28, 2011 Hi you all, I know that some of you know where these things can be found besides just at Micro mark. I'm in search for these weighted drill bits to use in a dremel. Any help would very greatly appreciated. Thank you.
Bobdude Posted June 28, 2011 Posted June 28, 2011 Jim,I am not familiar with the term weighted drill bit.Any drill bit you put into your Dremel will be limited to the size of the collet you have in the tool,unless you have a drill chuck made for the Dremel.Your local hardware store should have the sizes that you need.
Longbox55 Posted June 28, 2011 Posted June 28, 2011 I looked on Micro Marks site, the only bits I saw were the regular drill bits for Dremels, Those are also readily available at any hardware store, try Menards or Lowes.
MoparWoman Jamie Posted June 28, 2011 Author Posted June 28, 2011 I apologize for not being more clear on my question, I guess they might be called something different. I was told they was weighted drill bits. But to help out here with some more info, the bits I'm talking about has a color ring around them on the bits that can slide off and on depending if you apply enough weight to the rings that is. Here is a photo of one. Where all kind I find these ones at?
Longbox55 Posted June 28, 2011 Posted June 28, 2011 I've never seen anyhting like that before. What's the purpose of the weight?
MoparWoman Jamie Posted June 28, 2011 Author Posted June 28, 2011 Harbor Freight I just check they do have them, but the thing is, they state on their web site only sold in stores only. I don't have one of their store near me though as I am aware of. Thanks for the info though, at least I know one place now that carries the stuff.
MoparWoman Jamie Posted June 28, 2011 Author Posted June 28, 2011 I've never seen anyhting like that before. What's the purpose of the weight? Wwll the weight kinda isn't really a weight to what it looks like, the blue one here on the side has a number #57 on it. I have another one with a #54 on it that is also blue.
XJ6 Posted June 28, 2011 Posted June 28, 2011 Well to my understanding...the drill bit is set up for the depth of the hole to be drilled...for once you are at the "Blue Stopper"..also it appears the bit is to counter sink at the end of the drilled hole...Gee hope i am making some sense...CHEERS....
Bobdude Posted June 28, 2011 Posted June 28, 2011 After seeing the pic,what you have is a solid carbide drill with the standard 1/8" shank.As stated before,the ring with #57 on it is the size of the drill.Carbide drills are more expensive than High Speed Steel drills an also more brittle,they snap off easier.You can look on Ebay,search for carbide drills,you will be surprised how many of them are listed.
crazyjim Posted June 28, 2011 Posted June 28, 2011 Now I see. It's not a weight but an identification collar. I use high speed drill bits in my Dremel and they have the same size shank as the bit. They're tiny bits that come in sets of about 20 in a little case. Micro Mark has them but that place is expensive.
Art Anderson Posted June 28, 2011 Posted June 28, 2011 That is what is called in the trade as a "center drill" (I have a bunch of them here, used with my Sherline Mill) Center drills are meant to be used in drill presses (or as with me, I use my Sherline Mill as a drill press--witness the 550 holes I drilled in the aluminum cylinder for the cooling pins!). They are carbide, which is quite brittle, and if used in a pin vise, or in a hand-held power unit such as a Dremel tool, will break almost instantly, as carbide doesn't flex very far before it shatters. The colored collars on the ones that come in sets from Harbor Freight are there for diameter ID, makes it easy to remember what size the drill is, not a weight. Art
Terry Sumner Posted June 28, 2011 Posted June 28, 2011 Art...it's not a center drill. It's just a small carbide drill bit with an identification collar on it. These bits are, as has been said...very brittle and break easily. They don't stand up well to the forces placed upon a true center drill. I have many of those bits and just as many broken ones too! LOL Here is a photo of an actual "Center Drill". Hosted on Fotki
Mike Kucaba Posted June 28, 2011 Posted June 28, 2011 The ring is a convenient grip for using them with your fingers.
Bobdude Posted June 29, 2011 Posted June 29, 2011 Terry, Cool pic of the center drill.I have a few of them in my toolbox.
Steve Keck Posted June 29, 2011 Posted June 29, 2011 These drills are used in CNC manufactured printed circuit boards. They are used a pre-set number of times before being resharpened or discarded. I bought a 55 piece assortment years ago for $5. Search out and make friends with the tool room manager at the printed circuit board company around the corner. He might just tell you when the next discard date is.
MoparWoman Jamie Posted June 29, 2011 Author Posted June 29, 2011 I just wanted to say thanks to those who helped out with info. I did learn a few things also about the bits from you all.
