Machinist Kalc Programs

As a machinist, it's important to know the names and location of each part of a drill bit. Because each part has a specific function, and knowing the functions makes them easier and safer to use. I'm providing a basic download to help you better understand drill bit nomenclature. Please contact me if you're unable to download this simple tool . More on drill bits will be available next month. Until then, take care. www.MachinistKalc.com

Today's download  is 8 MB, 53 pages long, and provides formulas  for trig functions that every machinist will use most of the time. Find the sine, cosine, tangent, cotangent, secant, and cosecant of angles. Download the file to your phone or print and keep it nearby for these types of jobs.

Every machinist deals with right triangles on a regular basis, so my gift (a.k.a. machinist tip) to you this month is this highly beneficial 2-page PDF document, because it's impossible to remember ever formula. Download and/or print this handy PDF file of formulas to calculate right triangle sides and angles .  Merry Christmas from www. MachinistKalc.com . 

Today I'm offering a PDF download of a Table of Squares and Square Roots - a must-have for any machinist. The table provides N 2  and √ for numbers ranging from 1 to 100. Just click on the link above to download and print, and keep it in your wallet or toolbox. If you have the capability of saving PDFs to your smart phone, it may be easier to keep this table at your fingertips. If you aren't able to download PDFs to your device, you can save it to your Google Drive and open it from there on your phone. Thanks for visiting MachinistKalc.com .

I hope you enjoy this free chart that covers drill letter sizes from A to Z. Conversions are decimal equivalents as partially shown below. Print out the conversion chart or save to your smart phone so you will have this readily available whenever you need it.  Thanks for visiting www.MachinistKalc.com .  

In case you're just finding MachinistKalc.com, I want to let you know that you will, first, need to download the GraphNCalc83 calculator app onto your iPhone in order to use my programs from this website. I'm not affiliated with this app or the creator in any way. It's simply a great app that I use to double check my own calculations as a machinist. Woodworkers and hobbyists will likely find many of these calculator programs helpful as well.  Since my iPhone is always with me, it's easier to use this app than it is to carry a TI83 calculator around or a Machinery's Handbook. I thoroughly check these programs before releasing them. However, I want to stress that these are to be used for double checking your own calculations and not as your main source of calculating. Please see my disclaimer page for more information .  In this free package, you'll receive the NPT (National Pipe Taper), NPS (National Pipe Straight), and BSPP/BSPT (British Standard Parallel Pipe/...

Decimal Equivalents of Number Size Drills is our August 2023 tip. If you frequently use numbered drills, you'll want to print this PDF and keep it nearby at all times. You'll be able to easily find the decimal sizes for drill numbers 1 through 80. Please contact me if you have any problems downloading the PDF or if you have any questions or recommendations for tips. If you haven't done so already, be sure to sign up for my newsletter at the top of the page so you don't miss any monthly tips or new GrafnCalc program releases.  Thanks for visiting www.MachinistKalc.com . 

Using Common Angles and Standard Pins to Calculate Gibs and Dovetails In this PDF download , you will receive standard pin diameters in fraction and decimal form from 3/64 inch (0.04688) to 2inches (2.000) for 45- and 60-degree angles for E, F, and G. Thanks for visiting www.MachinistKalc.com today. These tips are some of the best tools a machinist can have. I also have more Machinist Tips available.

Can you imagine a world without threaded  nuts and bolts? When you think about it, almost everything in the world is held together by nuts and bolts - vehicles, homes, bridges, chairs just to name a few. You could say that our lives are literally hanging by a thread.  Of course, threads are used in other materials as well such as pipes. And threads come in different pitches; some are standard and some are metric; some are internal and some are external. And it's a machinist's job to make sure these threads are precise for the jobs they must perform. So, as a veteran machinist with over 40 years of experience, I have posted a few thread tips and created some GraphNCalc83 programs to help you double check your calculations for external pipe threads , internal pipe threads , and for diameter calculation  over three-wires of 60 degree threads.
