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.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application relates to and claims the benefit of U.S. Provisional Application No. 62 / 460,529, filed Feb. 17, 2017 and entitled “HOLE SAW GUIDE,” the entire disclosure of which is hereby wholly incorporated by reference.STATEMENT RE: FEDERALLY SPONSORED RESEARCH / DEVELOPMENT[0002]Not ApplicableDESCRIPTION OF THE INVENTION[0003]The present invention relates to general construction tools. In particular, the present invention relates to a hole saw guide for facilitating the drilling of a circular opening through surfaces where prior holes may or may not exist and where a pilot bit (also known as a centering bit) may or may not be used.[0004]A hole saw is commonly used to cut large holes through surfaces. Complete hole saw assemblies are typically comprised of a hole saw blade, which is a cylinder with cutting blades or abrasive material on an open side of the cylinder, the blades or abrasive material of which are parallel to the surface o...

AI Technical Summary

Benefits of technology

The present invention provides a hole saw guide for facilitating the formation of an opening in a surface. The guide comprises a transparent disk with concentric grooves on its surface that act as a guide for a hole saw of desired diameter. The guide can be easily mounted on the surface and is able to stabilize the hole saw during use. This invention improves the accuracy and efficiency of hole formation and is particularly suitable for use in construction and drilling applications.

Problems solved by technology

First, if a hole already exists in the substrate at the desired location of a larger hole, then there is no surface on which to position the pilot bit of the hole saw assembly.

As such, absent the pilot bit providing an axis around which the hole saw rotates, it is practically impossible to position the hole saw at the desired location or contain the hole saw at its desired position when the hole saw is rotating.

Furthermore, absent a pilot bit providing an axis for the hole saw, it is not possible to pierce the surface of the substrate to stabilize the hole saw at the desired location and from kickback or sliding of the hole saw blade.

Such misalignment or kickback may result in a damaged surface and misshapen hole.

At worst, an entire surface may be destroyed and the operator of the drill fitted with the hole saw may be injured.

In addition to problems arising from a lack of pilot bit, it is oftentimes impossible for an existing pilot bit to drill into a substrate if the pilot bit is not constructed with a shape and materials composition that is able to penetrate the substrate material.

While the devices disclosed therein may provide a limited solution for hole saw drilling, the tool is insufficient for general hole saw use.
