Abstract

A tool for chamfering plastic soil pipes comprises a main body section 1 provided with an abrasive area 2 mounted on a tapered surface 3 of the main body 1. The outer diameter of the tapered surface 3 is greater than that of the pipe to be chamfered, thereby allowing for variation in pipe diameter. The abrasive is carbide grit which has been brazed onto the tapered surface 3 which is steel. The abrasive occupies 20-50 % of the tapered surface 3. The tool can be fitted to a drive mechanism by means of a thread 4 or a taper.

Description

1 2453791
Title of invention
Soil pipe chamfering tool
Field of the invention
This invention provides a method of chamfering plastic soil pipes for use in push fittings to help prevent the seal in the fitting being damaged during assembly.
Background of the invention
When using plastic waste pipes in conjunction with push fittings' it is helpful to chamfer the outside edge of the pipe so that the seal in the fitting is not damaged during assembly. Current methods of achieving this may be to use an angle grinder to chamfer the pipe or a file, both of these methods are awkward and may easily lead to personal injury. Other similar tools are available but due to the cutting being done by a sharp tip the process is aggressive and when the pipe is being held by hand an aggressive power tool can be dangerous.
Object of the invention The object of this invention is to produce a non-aggressive device to be used in a power drill that can be used to chamfer plastic waste pipes to be used with push fittings' to help prevent the seal in the fitting being damaged during assembly.
Summary of the invention
The invention is a solution to chamfering plastic soil pipes comprising of: i) A main body section (1) ii) With an abrasive surface (2) mounted on a tapered shoulder (3) iii) And a method of connecting a multiple drive adaptors (4) to suit various power tool drive mechanisms Advantages of the invention When using plastic soil pipes in conjunction with push fittings' it is helpful to chamfer the outside edge of the pipe so that the seal in the fitting is not damaged during assembly. Current methods of achieving this may be to use an angle grinder to chamfer the pipe or a file, both of these methods are awkward and may easily lead to personal injury. Other similar tools are available but due to the cutting being done by a sharp tip the process is aggressive and when the pipe is being held by hand an aggressive power tool can be dangerous.
Preferred optional features The product should be made from steel The abrasive surface should be formed using carbide grit The inclusive angle of the taper should be approximately 300

Detailed description of the drawings
A tool for chamfering plastic pipes comprising of a main body section (1) provided with an abrasive area (2) mounted on a tapered surface (3) for engaging the work piece where the outer diameter (OD) of the taper is slightly greater than that of the pipe to be chamfered with extra tolerance to allow for variation in pipe diameter. The main body is also provided with a method of attaching various drive adapters (4)
