A tubing cutter for cutting thin walled metallic tubing of the type used for electrical conduit. The tubing cutter is of the type which supports the tubing being cut between a roller or rollers and an oppositely disposed rotary cutting wheel of a given radius located within the head of the cutter, the cutter being rotated around the tubing to cause the cutting wheel to cut into and through the wall of the tubing. The cutter is prevented from cutting all the way through the wall of thin walled metallic tubing by means of a depth gage stop member which contacts the tubing to terminate cutting. The depth gage stop member can be stationary or rotary, and is comprised of a pair of legs or rollers placed on each side of the rotary cutting wheel. The length of the legs or the radius of the rollers are less than the radius of the rotary cutting wheel by a distance that represents less than the wall thickness of the tubing to be cut.

1. In a tubing cutter including a roller or rollers and an oppositely disposed rotary cutting wheel, the tubing to be cut being supported between said roller or rollers and said cutting wheel, said tubing cutter adapted to be rotated around said tubing while advancing said roller or rollers towards said cutting wheel to thereby cause said cutting wheel to cut into the wall of said tubing, the improvement for cutting thin walled metallic tubing comprising disposing a depth gage stop member adjacent each side of said rotary cutting wheel, each of said stop members having an outer terminus which, when said cutting wheel first contacts the outer surface of said tubing, is removed from said outer surface of said tubing a distance that is less than the wall thickness of said tubing, whereby during cutting of said tubing by said cutting wheel the outer terminus of each of said stop members is adapted to come into contact with said outer surface of said tubing being cut before the rotary cutting wheel has cut completely through said wall of said tubing to thereby terminate the cutting action of said rotary cutting wheel.
