Tutorial on making a drill bit in SolidWorks.
Here is the Tutorial.
Start SolidWorks in Part mode.
Front Plane>>Sketch and draw a circle.
Select the front face of the cylinder>>sketch.
Make two circles.
Extrude cut it.
Make a profile like this one.
Revolve cut it.
Select the body as the flex input. Change the type to twisting and enter an angle value of 300 degree or something like that.
Click OK and we have the drill bit.
Great Help Thanks
Thats pretty neat and easy never thought about designing a drill bit
If you make a drill like that it won't cut. Flexing could be used to remove the need for the helix, but the chisel angle and cutting edges do not exist with this simple revolve. Even if they did, there's no back clearance so the drill would break or the item being drilled would melt.
