Drill and Tap Tool - Thread Tapping & Through Hole App Description

iOS 10 compatible! Whether you use Metric taps and drills, US Standard taps and inch drills, or any combination of size types, this app has the answers. No typing required; just tap your thread type and spin the dials to find the correct size of drill for your thread tapping operation. The interface allows for selection of the following variables to calculate your required drill size: • Thread Type, • Tap Size, • Percentage Depth of Thread, • Through Hole Clearance, • Cutting or Forming Operation The closest drill bits are given in Metric, Fractional Inch, and US No. / Letter sizes, making this the perfect tool for those using a mix of tap and drill types. The app ensures complete control and accuracy of your operations by recalculating the actual percentage-depth-of-thread and through-hole clearance for each closest drill bit size. Thread types include: • US Standard UNC, UNF, UNEF • ISO Metric coarse, fine • National Pipe Thread - Tapered (NPT) • National Pipe Thread - Straight (NPS/NPP) • British Pipe Standard Thread - BSP (Parallel - G) • British Pipe Standard Tapered Thread - BSPT (Parallel - R / Rp) A helpful reference tool for engineers, machinists, trades-men, students, tool makers, DIYers, fitters and turners, and fabricators, etc.

  • Best tap drill app

    I use this app daily when setting up new jobs and converting older jobs from cut tap to form tap sizes. Often multiple times per job and per day. Having tried many machinists related apps, I find the information in this one very well presented and accurate. The ability to adjust tap hole size for difficult materials or deep threads and know what percentage of thread engagement should be created if the tools cut properly is very nice. Easy to play "what if." Tap charts usually give drill sizes based on 65 or 75 percent engagement. When a form tap doesn't meet minor diameter requirements, using this app can help quickly determine if a smaller drill will be risky by showing what percentage thread the new hole size should generate. Sometimes drills don't drill to size for various reasons, tools wear, and materials can be difficult. When troubleshooting I find myself pulling up this app to verify drill size and then check the drill being used and resulting hole diameter. From a long time user of this app, It's easy, accurate, and far more useful than a simple tap chart. Thank you for a wonderful tool and please keep it future proof.
  • Needs better thru hole options

    Thru hole selection is done by changing depth of threads to zero percent. Doesn't give thru-hole with NPT threads - the only reason I bought this!

    Exactly what I was looking for. I would recommend this app.
  • Very good

    I would like to see the British Association "BA" tap / drill sizes added.
  • More than just a drill chart

    Very helpful app for calculating my drill sizes for tapping in different materials. Let's me use a large percent thread depth for plastics and a lower percentage for steel etc.
  • Needs a white selector wheel

    By Dr. Stu
    Update is nice BUT the black/grey on grey selector wheel is really hard to read and out of place with the rest of the color scheme. Please change to a white background wheel, then it gets 5 stars. Update: Developer responded to my request very quickly - now the selector wheel is legible! - excellent app now.
  • Simple complete fast accurate

    If you are a "maker" you will find this app has everything you want to know before you cut threads.
  • Great Application

    I usually don't write any reviews but this application deserves one. It is very useful for my type of work, very simple to use and complete. Customer service is also great. They responded to my request in less than 24 hours. I surely will buy more applications from this developer.
  • Very Useful!

    Very handy to use along with a caliper. I have found it especially useful for finding the correct drill to use when I want the entire screw to fit cleanly through the hole. The ability to set thread depth is also great! Also great for correlating English and Metric sizes.
  • Great app

    This is one handy app for the busy machinist I highly recommend it
