Depth Micrometers 449 Micrometer Depth Gages with Non-Rotating Blades 0-6"/0-150MM By holding the base in one hand, the .045" thick x 1/8" wide (1.2 x 3.2mm) blade can be turned with the fingers and positioned at any angle relative to the base. In operation, blade does not turn, but moves perpendicularly only, permitting depth measurement of narrow shoulders without the blade rolling off. This is also ideal for slots and recesses as narrow as .045" (1.2mm). Furnished with a 2-1/2" (63mm) or a 4" (100mm) base. Also available with 3 rods for measuring 0-3" (0-75mm), or 6 rods for measuring 0-6" (0-150mm) in thousandths of an inch or 0.01mm. This tool comes with the combination ratchet and speeder for uniform pressure and quicker adjustment. 449AZ-3R 449 Micrometer Depth Gages (.001" Graduation) Cat.
