  • sizing drill bits to match blades

    I've been scrolling for quite a while and have always had access to drill bits from local businesses, particularly Lowes and Home Depot. The smallest they have is 1/16", which is too big for most of my scrolling.
    So, I still need to check Sears and Hobby Lobby to see if they have anything smaller.
    My question is, most bits have numbers like 60, 63, etc. What number corresponds with something that is about half the size of a 1/16" bit? I went to Mike's Flying Dutchman site and 63 seems to be the best answer, or is that too small?
    Help?? Any comments and suggestions will be very much appreciated.

    I forgot to say that most of the time I use a no. 5 blade or smaller. What size bit is best for no. 3 blades, or smaller?

      I figured out bit size by taking my favorite blades to a model railroad hobby store, and did them by eye......

        Mike does provide the width of the blade and a #63 should be the drill for SR #5. A #65 should be the bit for a SR #3. There are several web sites that provide charts for drill bit sizes if you know the width of your blade. Here is a no nonsense chart I use to determine size - Drill Size Conversions -- Technical Notes

          Here are couple references I have used...look at the Olsen Chart and it will tell you what they recommend and sizes, if you need sizes by OD then use the New York Drill Chart.

          There are a couple places that you can actually buy drill bits just for scrollers one of them on the internet is: Drill Bits. I have also found some locally at the Harbor Freight store, they are not marketed for scrollers, but they are tiny and do the trick! However, they are not super long, so they do not work if drilling at angles in thick wood for bowls or inlays. You do have to be careful as they do break fairly easy. Using a drill press you may have to buy an additional collet so you can chuck them in your press.

          I hope it helps and good luck in your search!

                Bubba, the smaller bits are called wire bits and come in sizes from about #54 (the biggest) to about #85 (the smallest). I use a #54 for a #5 blade and a #61 for a #2 or 2/0 blade. You can get them from Mike, Sloan's (in Tenn), or Wildwood-CherryTree.

                A day without sawdust is a day without sunshine.

                    If you have an Ace Hardware near, some carry a set of wire bits 60 to 84

                      Home Depot and Lowes usually have them but you need to look by the Dremel accessories.

                      In God we trust, all others must pay cash!

                      I don't want no bargains, they always cost me more money.

                          I get my bits and the collet from Mike. One trick I have found with any small bit with and without a collet, is to place the bit against the wood before you start the drill press. I have fried several collets for small bit and none of them had a straight spin. When they are against the wood thy have no place to go...

                          When a work lifts your spirits and inspires bold and noble thoughts in you, do not look for any other standard to judge by: the work is good, the product of a master craftsman.

                              As a framer, we have a shrinker wrapper at ArtCrafters. Very simple. Film on a roller, sealer attached, just roll off enough film, seal the film, insert object, seal other end and shrink with a heat gum. We also use Uline as a source. Not sure where our unit can from as it was with the shop when...

                              I shrink wrap all my puzzles. It is the best method I have found. I do not use a cardboard backer as some do. I use shrink wrap bags that I get from Amazon or Ebay. 8" x 12" will fit 95% of the puzzles I make.

                              To use the bags you will need a sealer. I have one very similar...
