1.  Thread Section
    Unified Screw Thread Database containing over 500 records including upper and lower limits for Minor, Major, and Pitch diameters from 0 to 4" in diameter. This page links to the thread wire calculator, feed rate calculator and the single point thread cutting path page.
    Metric Thread Database including upper and lower limits for Major, Minor, and Pitch diameters from M1.6x0.35 to M200x3. This page will also convert 'metric specs' to 'decimal standard' (including TPI, major, minor and pitch) simply by clicking a command button.
    Thread Calculator for generating specs for standard and non-standard threads. These calculations are based on both thread form and threads per inch requirements. This page also contains the 'Over Wire Calculator' showing both upper and lower limits and 'Best Wire Size' for those measurements.
    Feed rate Calculator for both 'inches per revolution' and 'inches per minute' applications.
    Single Point Thread Cutting Calculator. Simply input the desired number of passes, select 'internal or external' and you will have each pass identified by diameter and depth of cut.  Also an option to compensate if you use your lathe compound settings. This is based on equal volume of material removal per pass.
2. Tool Path Pages
This page will allow you to input dimensions from your print to automatically calculate a multiple Radius, or Angle to Radius blend configuration. It Gives you point to point locations in a common CNC type format. Very easy to use with many features such as tool radius compensation and I,J,K information. Our Most Popular Section!
3. Cutting Speed Section
A database containing 1000 records on materials, hardness and conditions. Enter the diameter of your live tooling or material and instantly have RPM calculations for turning, milling, drilling and reaming for both steel and carbide tooling. Also a Feed rate calculator based on chip load and the number of cutters. Want to know what your current SFM is? Enter your rpm and tooling/material size for quick results. Now with a hardness conversion datbase table (Rockwell/Vickers/Knoop)
4. Trig Calculator
Very easy to use, point, click, enter your 2 known values and the rest is automatic.
Now with an Oblique Triangle Calculator page! Easy To Use!
5. Hole Patterns
Enter the number of holes and the size of the pattern and the rest is a click away. Gives both absolute and incremental locations from either of two reference points. (edge or center) of pattern.
6. Polygons
All you  need is 1 known value to find out rest. Triangles, squares, pentagons, hexagons, and octagons. Very easy to use.
7. Value Convertor
Quickly convert distance, area, volume and weight. (includes metric) Comes in very handy!
8. Chamfer Measurements
This page will give you the proper depth needed to achieve a given chamfer diameter based on the chamfer angle. It also gives you a method of measuring chamfers based on a 'ball over chamfer' extension ( ball height converted to chamfer diameter)
9. Materials Weights Database
This will easily calculate your material needs. Select your material shape (Round, Tube, Hex, square, rectangle) Enter your part length, cut-off tool width, material size, and order quantity. Then you can enter the weight of the material (Cu.Inch/Cu.Ft.). (Access updateable database reference of metal and wood weights included!) Enter your price per Lb. and it will calculate the cost, and the amount of feet needed with (bar length/bar end) compensation.
