Description
Product Overview
When you need to set up angled milling operations, verify the tilt of a machine spindle, or inspect heavy fabricated weldments, a standard block level is useless. The Obishi Keiki 45-Degree Adjustable Inclination Level (No. 01592) is a highly specialized Japanese measurement instrument that combines the sensitivity of a master level with the angular versatility of a precision protractor.
- 0 to 45-Degree Range: This level allows you to measure and set precise angular inclinations up to 45 degrees in both flat and perpendicular orientations, offering an incredibly fine 1 Arcminute minimum reading.
- Fast-Feed Mechanism: Setting angles across a 45-degree sweep by turning a micro-dial takes forever. Obishi solved this beautifully—simply pull the dial knob outward to release the internal gear mating. This allows you to rapidly swing the level to your rough angle, push the knob back in, and dial in your final micro-adjustment perfectly.
- Dual Bubble Chambers: Features two high-sensitivity glass vials (one for flat and one for perpendicular orientation) so you can maintain strict levelness no matter how the tool is positioned.
- V-Groove Base: The precision-machined measuring base features a V-groove, ensuring it sits completely stable on cylindrical shafts, round machine columns, or flat milling tables.
Condition
Used (Shop Grade / Shows Surface Wear).
We believe in total transparency when it comes to precision metrology tools. This inclination level has seen active duty and is being sold in “shop grade” condition.
- Surface Condition: The V-groove bottom reference surface exhibits visible marks and scratches that can be felt under the finger. Because of these tactile surface imperfections, this is no longer a sterile, aerospace-grade inspection tool. However, it remains highly capable for general shop setups, angled milling, and fabrication layout.
- Cosmetic & Mechanical State: The painted body shows noticeable scratches and chips from normal shop use. Despite its outward cosmetic wear, the internal mechanics are fantastic. The gear engagement is tight, the fast-feed pull knob works exactly as intended, and the glass vials are completely intact and readable.
