Hole cutting system
A material removal system enabling the installation of electrical outlet boxes and junction boxes among others, includes a platen for attaching to a vibrating movement, a blade with teeth having any circular or non-circular cutting edge which attaches to the platen that vibrates the teeth multidirectionally. The system enables rapid material removal and produces a clean rectangular aperture requiring little or no modification prior to installing an outlet box.
1. A material removal system enabling the installation of inserted objects such as electrical outlet boxes and junction boxes into a material, comprising:
(1) a housing for a motorized agitating movement having an agitation path;
(2) a platen connectable to the motorized agitating movement;
(3) a single blade assembly having a toothed edge, and opposite the toothed edge, a non-toothed portion which is removably attachable to the platen wherein the single blade has a continuous cutting edge configured to remove a cylindrical or non-cylindrical shaped section from the material, and wherein the motorized agitating movement is configured to agitate the toothed edge and the non-toothed portion of the single blade assembly in unison along the agitation path; and,
(4) at least one piercing guide for piercing the material which extends from the housing for guiding and stabilizing the housing so that kinetic energy from the motor is transferred to the cutting edge when it is plunged into the material.
2. The system according to claim 1 , in which the blade's cutting edge and non-toothed portion is substantially gapless.
3. The blade assembly according to claim 1 further comprising a blade coupling means whereby the blade and platen are secured together.
4. The system according to claim 1 , in which the blade assembly is interchangeable with a differently shaped or sized blade assembly.
5. The system according to claim 1 further comprising oscillating mechanical movement.
