While tape measures are a staple of any toolbox or carpenter's belt, the time necessary to take a measurement and mark a material every time a cut needs to be made quickly adds up. The M1 Caliber Measuring Tool eliminates the need to measure and mark materials, significantly lowering the time to make cuts, increasing safety by keeping measuring related activities in a central location, and providing a hassle-free experience allowing professionals to measure and cut materials without stopping to mark them. The M1 Caliber is a digital measuring tool that works by sliding material underneath its wheel. The M1 Clamps directly to saw fences. The blade width is automatically compensated for and units can be displayed in both English and Metric units on a large, backlit, LCD display. The M1 can make a wide range of cuts including angled, beveled, miter, and compound cuts and is accurate beyond 1/32 (0.5mm). It is powered by 2 AA batteries (not included). It can work on both the left side and right side of the saw fence and digitizes any measurements taken on your miter saw, chop saw, or band saw. An automatically adjusting spring loaded arm allows the M1 to work with a range of material thicknesses along with material types ranging from wood to composites to metals.
