Deburr-It Bit

Abstract

The Deburr-It Bit is a versatile tool bit designed to be used manually with smaller size circular hollow ridged tubing or with a motorized drill during the installation of all types and sizes of circular hollow ridged tubing. The function of the Deburr-It Bit is to remove burr that is formed on said tubing when the tubing is cut with various types of saws and cutting tools. In most cases, the removal of burr allows the circular hollow ridged tubing to easily slip into the manufactured fitting orifice found on all fittings which could include elbows, valves, couplings, adaptors, and most types of connectors. It should also be noted here, that removal of burr, on the inside edge of circular hollow ridged tubing, is necessary to have a smooth unrestricted surface for the best fluid flow possible. The purpose of this Deburr-It Bit is to completely remove burr from the inside edge of said tubing, the outside edge of said tubing, and release burr waste debris particles to the atmosphere at the same time during said bit rotation. What is unique is the beveled circular double-wall V-shaped abrasion cavity surfaces of the Deburr-It Bit, that when in contact with said tubing, will remove the burr from both the inside edge of circular hollow ridged tubing and outside edge of circular hollow ridged tubing at the same time and in a shorter amount of time, resulting in two smooth unrestricted tubing surfaces. There is no need for expensive machinery.

Description

DESCRIPTION OF DRAWINGS

[0016] FIG. 1. The said bit (A), its design and details are focused on its use, requirements, and applications for trades and industries that require circular hollow ridged tubing. The top planar surface (8) of said bit (A) and its abrasion V-shaped cavity (10) with abrasion cavity wall A (2), abrasion cavity wall B (4), and changeable shaft (6) is designed with a thickness, quantity, and quality of abrasive material to give strength to said bit (A). Ergonomic cupping shallows (16) can be added for comfortable manual hand rotation.

[0017] FIG. 2. The top view of said bit (A), details the top planar surface (8) and its abrasion V-shaped cavity (10) with abrasion cavity wall A (2), abrasion cavity wall B (4), and changeable shaft (6) for manual hand rotation or motorized drill attachment. The size, cavity diameter, and composition of abrasive material of said bit (A) can be adapted to any size, composition, and schedule of said tubing. Circumferential ergonomic cupping shallows (16) can be added for comfortable manual hand rotation.

[0018] FIG. 3. To permanently remove burr debris particles, said bit (A) has a non-abrasive circular burr receiving channel (14) functioning in conjunction with attached, periodically spaced non-abrasive circular debris hollows (12) is capable of discharging to the atmosphere all burr debris particles during the rotational deburring process.

[0019] FIG. 4. The cross-section in FIG. 4 details the planar surface (8), the circular V-shaped abrasive cavity (10) with circular abrasive cavity wall A (2) and circular abrasive cavity wall B (4), and a changeable circular shaft (6) for manual hand rotation or motorized drill attachment. A short distance from the outer edge on the top planar surface (8) of said bit (A) is a circular V-shaped abrasive cavity (10) that extends down to a non-abrasive burr receiving channel (14). The walls of this circular V-shaped cavity (10) are not perpendicular to the top planar surface (8), but are beveled towards each other and attached to a non-abrasive burr receiving channel (14) to which are attached non-abrasive circular debris hollows (12). Extending down through the Deburr-It Bit (A) is a changeable centered shaft (6) which will act as the attachment to a motorized drill or removed for hand held rotational deburring.

[0020] Burr debris particle removal begins with the insertion of said tubing into the V-shaped cavity (10) where said tubing will make contact with abrasive cavity wall A (2) and abrasive cavity wall B (4). Upon rotation of said bit (A), burr debris particles will fall into the circular non-abrasive burr receiving channel (14) due to gravity. With continued rotation of said bit (A), the particles are moved through said channel (14) and out through the circular debris hollows (12) to the atmosphere due to inertia, the lack of centripetal forces, and the unequal air pressure difference between the outer edge of the debris hollows (12) and the V-shaped cavity (10) due to Bernoulli's Principle.

[0021] FIG. 5. A changeable circular shaft (6) extends down through the said bit (A), will become the attachment for rotational deburring where the diameter and length, will be determined by the size and composition of the circular hollow ridged tubing. For smaller size circular hollow ridged tubing, rounded and cupped edges (16) of the said bit (A) will make said bit ergonomically comfortable to hold and use as a hand tool without shaft (6) or a motorized attachment. Circular debris hollows (12), periodically spaced connects the circular non-abrasive burr receiving channel (14) to the atmosphere. As stated in FIG. 1, the outer terminal ends of the periodically spaced non-abrasive circular debris hollows (12) are shown and referenced.
