Description Product Overview When you need to measure the root diameter of a spline, the depth of an O-ring groove, or a narrow keyway, standard flat-anvil micrometers simply cannot fit. The Mitutoyo 121-101 Blade Micrometer is a highly specialized metrology tool engineered to reach into the tightest, most restrictive machining features with absolute precision. Ultra-Thin Blade Anvils: The defining feature of this micrometer is its blade-style anvil and spindle. Forged down to a razor-thin profile, these blades effortlessly slip into narrow slots and undercut grooves that are completely inaccessible to standard measuring tools. Non-Rotating Spindle: To measure a groove accurately, the blade must stay perfectly aligned with the slot. Mitutoyo engineers this micrometer with a specialised non-rotating spindle. As you turn the thimble, the spindle advances straight outward without twisting, ensuring the delicate blades never bind or drag against the walls of your workpiece. 0-25mm Range: Covering the essential 0mm to 25mm size bracket, making it a critical inspection tool for small-to-medium turned parts and intricate milling work. Satin-Chrome Finish: Features crisp 0.01mm graduations etched into a glare-free satin-chrome finish, reducing eye strain under harsh shop lighting and resisting rust over decades of use. Condition Used (Pristine Condition / Complete in Box). While technically a used tool, this blade micrometer is in absolutely pristine condition. It has been meticulously cared for by a professional machinist and shows practically zero signs of shop floor wear. Mechanical Integrity: The non-rotating spindle travels with legendary Mitutoyo buttery smoothness, and the delicate blades are perfectly parallel and completely free of chips or crash damage. Complete Setup: It comes safely housed in its original Mitutoyo factory protective case, complete with all original paperwork and the adjustment spanner setting tool. Brand Information Mitutoyo Corporation (Japan) is the undisputed global benchmark for dimensional metrology. Their specialty micrometers, like this blade-style unit, are heavily trusted in aerospace, automotive, and general job shops because they solve complex inspection problems while maintaining laboratory-grade Japanese accuracy.
