Description
Product Overview
Proper machine leveling is the foundational requirement for any precision shop. If your lathe bed has a twist or your mill is out of tram with gravity, chasing tight tolerances becomes impossible. The RSK 100mm Precision Machinist Level is a professional-grade Japanese layout tool designed to establish and verify absolute levelness during machine installation and maintenance.
- Compact 100mm Footprint: While giant master levels are great for massive bedways, a compact 100mm (approx. 4″) level is incredibly versatile. It is the perfect size for checking the alignment of smaller cross-slides, rotary tables, milling machine vises, and sneaking into tight structural webs where a standard 200mm level simply will not fit.
- Adjustable Main Vial: The primary glass vial is highly sensitive and engineered for micro-adjustments. Using the included Allen key, the vial can be recalibrated to absolute zero, ensuring your tool remains perfectly accurate for a lifetime of shop use.
- Precision Ground Base: The underside of the level is precision ground to strict Japanese industrial tolerances. It provides a flawless, flat mating surface that ensures the bubble reading is a true reflection of your machine’s geometry, without rocking or false high spots.
Condition
Used (Good Condition / In Wooden Box).
This precision level is in good, fully functional used condition and has been treated with the respect a layout tool deserves.
- Surface Condition: There is some visual, superficial surface patina present on the underside reference face. However, it is entirely smooth to the touch, with absolutely no pitting, dings, or raised surface imperfections that would compromise its seating or accuracy on a flat surface.
- Complete Setup: It comes safely housed in its original foam-padded RSK wooden storage box to protect the delicate glass vial from shop floor accidents. It also includes the original factory paperwork certificate and the crucial Allen key required for adjusting the bubble.
