Hole Features

Creating Hole Features

In this exercise, you will create four types of holes: Drilled, Counterbored, Countersunk, and Tapped. With Inventor, you can also create custom thread and drill point types to fit nearly any design requirement.

Hole Features Part 1

Save the Holeblock.ipt to your H:Drive, the file should look like the object pictured to the left.

To create a hole using the Hole Feature you will first need to place a point to tell the program where to "drill" the hole.

Select "Start 2D Sketch" from the ribbon and click the top surface of the cube to make it the active sketch plane.

Select the Point tool from the 3D-model ribbon. Dimension the point .75" from the top and left side of the block.

Finish Sketch.

Create a Simple Hole

Once the Center Point of the hole has been located, select Hole Feature from the Part Feature tool bar. The Hole dialog box will open. Hover your mouse over each button in the dialog box to familiarize yourself with the dialog box.

Create a Simple Hole with a diameter of .5" and a termination depth of .75" as shown to the left. Click OK.

Create a Counter Bored Hole

Repeat the steps just shown: Create a New Sketch plane on the top surface, use the Point Hole Center tool to create the center point of the hole, and Dimension it as is shown to the left.

Once the center point of the hole has been located, select Hole Feature from the Part Feature tool bar. The Hole dialog box will open. Depress the Counter Bore tool. Notice how the picture in the right side of the dialog box changes.

Enter a counter bore diameter/width of .675 and depth of .25. Set the termination depth to.75 and the diameter/width of the hole to .5. To change diameter and depth values, highlight the dimensions in the hole diagram and type the correct values.

Create a Countersunk Hole

Repeat the steps just shown: Create a New Sketch plane on the top surface, use the Point tool to create the center point of the hole, and Dimension it as is shown to the left.

Once the center point of the hole has been located, select Hole Feature from the Part Feature tool bar. The Hole dialog box will open. Depress the Counter Bore tool. Notice how the picture in the right side of the dialog box changes.

Enter a counter bore diameter/width of .675 and depth of .25. Set the termination depth to.75 and the diameter/width of the hole to .5. To change diameter and depth values, highlight the dimensions in the hole diagram and type the correct values.

Create a Tapped Hole

Repeat the steps just shown: Create a New Sketch plane on the top surface, use the Point tool to create the center point of the hole, and Dimension it as is shown to the left.

From the Part Features tool bar, choose the Hole feature.

Choose a Drilled Hole.

Place a checkmark in the Tapped box. Leave the Thread Type as ANSI Unified Screw Threads, Right Hand.

Change the Pitch to ½ -13 UNC.

Change the Drill Point from Angle to Flat. This will create a flat-bottomed hole.

Click OK to complete the tapped hole.
