WETMORE - TYPE 7 SHELL REAMERS

Furnished With Either High Speed Steel Or Carbide Tipped Blades

These adjustable reamers with left hand angle blades for right hand cutting are designed for the finish machining of steel, cast iron and brass. Oversize adjustment is provided for wear and regrinding.

The 1/8" projection of the blades over the end of the reamer body allows for end cutting and lets the chips fall off ahead of the reamer, so they will not clog along cutting edge of blades.

Sizes of this type of reamer are 1 1/4" to 6" inclusive.
