MITER SAW PROTRACTOR

109Tools Miter Saw Protractor can rotate 360° to measure and find any internal or external angle. Suitable for most materials or surfaces. The Protractor can provide measurement angle value dimension on the scale and four different miter cut values next to the scale.

This product is a convenient angle measurer that can measure angles and check miter cutting values immediately. In particular, this product shows precision within 0.03 degrees of measurement error. This product is a best-selling product that has been in development since 1997 and started selling in Korea in 2005. It is a product whose quality and durability has been sufficiently proven in the Korean tool market.

109Tools Miter Saw Protractor is equipped with standard angle value scales on both sides of the arms, and left and right edges. These scale graduations and slope measurements are based on the standard angle notation scale. Angles (Miter) are measured so that the angle value can be cut flat as well as perform compound miter cuts. In order to provide ease of use for miter cuts, four types of miter cut values are indicated in two rows that are marked on the two arms for easy cutting of the measured angle to the grid. Easily perform accurate miter cutting work without a jig.

We noticed that angular values marked on a international standard protractor are different from angular dimensions marked on the compound miter saw tray. Therefore the user of the compound miter saw can be confused by mismatching the cut-off values. So we've developed a Miter Saw Protractor that uses the angle value of the protractor in the right picture and the angle value in the compound miter saw in the left picture to extract the math and display the four miter cut values.

In particular, when installing crown moldings, I needed a tool that could facilitate miter cutting. Also, when working on a wooden house, it was very important to measure the angle when installing pipes and steel frames, and to check the angle especially when welding.

Provides flat miter cut angles / Cosine values for molding wihout a jig / Carpenter tools Woodwork / Steel frame and sheet.

Useful for any steel and panel work,
plumbing and sheet metal, inspection

How to use the product.
Just watch this instruction manual and how-to video.

You don't need a battery to use this product anymore.
It can be used in all weather conditions and is a durable product that can be passed down from generation to generation because it is an aluminum heat treated product.

Adjust the saw angle to the angle indicated on the inner arm, tighten and cut.

When using carpenter saw, angle grinder etc, measure corners of cutouts by retracting smart protractor.
Set to Standard Angle Values, place on material, measure and tighten locking nut. Mark the lines and cut.

When working with interior (crown) molding, you can cut easily and quickly using cosine angle cutting value data of the crown molding cut. There are two types of miter angle cutting values for crown molding: 1) at 45°/45° and 2) at 38°/52°, which are shown in the two lines next to the scale. The cutting value indicated by the “miter” arrow next to the scale is the cutting value that adjusts the angle of the workpiece as indicated on the compound miter saw tray on a compound miter saw. The cutting value indicated by the “saw” arrow is the cutting value that adjusts the angle of the saw blade portion of the compound miter saw. By adjusting the angle of the saw blade and the tray to the cutting value of the crown molding cut (Bevel), the crown molding can be placed on the saw’s tray flat without use of a jig so that the diagonal articulation by the cosine value can be done with ease.
