Hole saw guide

Abstract

A general purpose hole saw guide and a method of forming holes through surfaces, without the need of a centering bit, are provided. The hole saw guide includes a circular disk with concentric grooves on its surface. The disk is transparent and portable for placement on a surface through which a hole is to be drilled to facilitate the centering and stabilizing control of a hole saw on the surface. The method includes the steps of providing a transparent disk having concentric grooves; positioning the disk on a surface; mounting the disk to the surface; inserting a hole saw that is fitted to a drill into the grooves of the disk; drilling a hole through the disk and surface beneath it; and removing the disk from the surface after the hole has been drilled.

1 . A hole saw guide comprising:
 a transparent disk, said disk having on its surface a series of concentric grooves, said disk being destructible, said disk being able to be mounted to a flat surface.   
     
     
         2 . The hole saw guide of  claim 1 , wherein said disk is constructed from solid stereolithography (SLA) material. 
     
     
         3 . The hole saw guide of  claim 2 , wherein said disk is constructed through a computer numeric control (CNC) process. 
     
     
         4 . The hole saw guide of  claim 1 , wherein said disk is made by an injection molding process. 
     
     
         5 . The hole saw guide of  claim 1 , wherein said disk is made by an additive process. 
     
     
         6 . The hole saw guide of  claim 5 , wherein said disk is made by 3D printing. 
     
     
         7 . The hole saw guide of  claim 1 , wherein said disk has a diameter of about 9 inches. 
     
     
         8 . The hole saw guide of  claim 7 , wherein said disk has a diameter of about 9.4 inches. 
     
     
         9 . The hole saw guide of  claim 1 , wherein said disk has a minimum thickness of about 0.02 inches and a maximum thickness of about 0.12 inches, 
     
     
         10 . The hole saw guide of  claim 1 , wherein said disk has a groove depth of about 0.1 inches. 
     
     
         11 . A hole saw guide system comprising:
 a surface through which a circular opening is to be made;   a transparent disk having concentric grooves on its surface, said grooves defining a plurality of possible hole areas, said grooves able to contain and stabilize hole saws of corresponding diameters;   wherein said disk is able to be mounted to said surface;   wherein said disk is destructible, and disk material of said disk is removable from said surface after a hole through said surface is drilled by a hole saw.   
     
     
         12 . The system of  claim 11 , wherein said surface includes a prior hole where the circular opening is to be made. 
     
     
         13 . The system of  claim 12 , wherein the prior hole inhibits the use of a pilot bit with said hole saw. 
     
     
         14 . The system of  claim 11 , further comprising said hole saw.
