Features:Steel forging grinding molding, ensures high hardness, good wear resistance, and screw hole design for strong clamping forceAnti-skid rubber gasket, make clamp firm, and will not hurt the table surfaceNew jaw, suitable for different size and shape objectsIn order to ensure that the hole of the log pin is perpendicular to the joint surface, the log pin drilling positioner must be used when making the spanking furniture connected by the log pin.If direct drilling with hand drill will lead to hole deflection, using a hole locator can achieve good drilling position.Specification:Name: drilling locatorMaterial: steelWeight: 418 g / 14.7 oz(approx.)Package list:7 *drill sleeves5/6/7 8/9/10/12 mm7 *limit rings 5/6/7 8/9/10/12 mm1 *drill tray1* hex wrench
