Hole Drilling Guide

When drilling small holes, a hole drilling guide is a great tool to have on hand. A hole drilling guide has a base body that is opaque, a drill template, and a stop that ensures the drill goes into the exact position. The drill guide will help with creating precise holes with minimal material removal.

The body of a hole drilling guide comprises a plurality of faces that substantially conform to the internal cavity of an article. The guide also has a clamping lug 88 that secures it rigidly to an article. In addition, the hole drilling guide has multiple exit apertures and inlet apertures that penetrate substantially corresponding surfaces. These apertures may be conical, bell-shaped, or similar-shaped.

One embodiment of the hole drilling guide includes a hollow raceway, which can be inserted into a vane cluster. The guide is then rigidly mounted using a clamp and a clamping lug. After the hole drilling guide is securely mounted, an EDM electrode is loaded into the EDM station. The electrode then plunges through the airfoil wall, forming a hole in the surface.

A hole drilling guide is useful in a variety of settings. It can be used to drive screws and mount hardware, and create dowel joints. Many tools are available to help you accomplish these tasks.
