Miter Angle Cutters

Make accurate cuts at precise angles in material that is too pliable for a saw, such as weatherstripping, or too hard for scissors, such as wooden dowels. These cutters are often used to cut trim to create corners in door and window frames. The miter guide is notched to line up your workpiece. 8 _1/2" long cutters are notched at 15° increments. 8 _3/4" long cutters are notched at 45°, 90°, and 120°.

Replacement Blades—Cutters with a replaceable blade allow you to switch out the blade when it gets dull.
