Benefits of technology

[0005]A portable cutting device having a cutting tool for cutting a material is provided. The cutting device includes a motor driving the cutting tool and a protective housing at least partially enclosing the cutting tool. The protective housing defines a debris accumulation chamber for gathering debris created by the cutting tool. An impeller is operatively coupled to the motor and driven by the motor to create suction pressure to draw the debris out of the debris accumulation chamber and into a collection bag. A vacuum housing protects the impeller and the collection bag is coupled to the vacuum housing. The impeller and collection bag form part of an on-board debris collection system thereby eliminating the need for a separate off-board vacuum source and debris collection area.

Problems solved by technology

Additionally, the debris accumulates in the area in which the cutting device is being used making clean-up time consuming and difficult.

Embodiment Construction

[0050]Referring to the Figures, wherein like numerals indicate like or corresponding parts throughout the several views, a portable cutting device for cutting a material M such as wood, drywall, concrete, roof tiles, slate, etc., is generally shown at 30. The cutting device 30 is defined as being portable because of the ability to easily move the cutting device 30 between work sites. The cutting device 30 preferably weighs less than 50 lbs, more preferably less than 35 lbs, and most preferably less than 20 lbs. The cutting device 30 is also preferably handheld, such that it can be maneuvered, lifted etc. with a single hand.

[0051]Referring to FIGS. 1 and 2, the cutting device 30 includes saw casing 31 in which is disposed a motor 32 which drives a cutting tool 34. The motor 32 is preferably electrically powered and energized by a 110-volt outlet through a conventional electrical cord C, but the motor 32 could also be battery operated. The motor 32 has a main drive shaft 36 and the cu...

Abstract

A portable cutting device having a cutting tool for cutting a material. The cutting device includes a motor driving the cutting tool and a shroud at least partially enclosing the cutting tool. The shroud defines a debris accumulation chamber for gathering debris created by the cutting tool cutting the material. An impeller is operatively coupled to the motor and driven by the motor to create suction pressure to draw the debris out of the debris accumulation chamber and into a collection bag.
