MSC has anything you need.Thier catalog has charts and conversion tables in it, ect... I use it for info all the time. If it is made (drill-wise) MSC has it. There's a link on my web page. ......................BE BLESSED........................ |

When you get MSC you might consider a metric or a "number" sized drill, compare the decimal equivalent to the drill and get exactly the size you want. Hopefully, you're a weight lifter, if you have them send you a catalogue. It must weigh 20 lb.! |

Nathan. Glad you can handle that book! You cannot, I guess, get a drill exactly .223" there. But... you can come very close. I go a bit oversize so thet the screw will fit in the hole a little easier. Look on page 35 and 36 of the giant MSC book for screw machine drills. I like this type of drill because they are pretty short and stiff and you can get by using them without a center punch, most of the time. Other types of drills are in the same area of the book. 5.7mm = .224" order # 01293307 #1 = .228" order #01383017 "A" size = .2340" order #01384015 15/64" = .2344" order # 01382159 I hope one of these will work for you. On the handles screw holes, for the large 5/16" headed Corby-type bolts that I use, I use the 15/64" size, but the others would work. I use a #11 for the smaller, 1/4" head bolts. That's a slightly over-sized 3/16" drill. Take care, Steve P.S.. Now I need to rest, after lifting that book around! |

If you have to have it exactly .223, get a larger drill, spin it backwards with a smooth sharpening stone to hone it to the exact size. You can also get reamers made to any size. a reamer in an undersized hole is the best bet for repeatable accuracy. |
