Selecting The Right Tool
The old saying, “you’ve got to have the right tool to do the job right”, is so true in regards to advanced drilling
equipment. For certain applications, as shown in the diagram below, a specific tool is required. However, other
applications may be served by more than one tool. Detailed analysis by one of our experienced technical
assistants will help you make the right tool selection for your particular applications. Some factors to consider are
fixturing costs, access, hole quality, material(s) being drilled, production rate, budget, and familiarity with product.
