extra-low voltage<\/li><li>The economical alternative for on-site use<\/li><li>and in the workshop<\/li><\/ul><h3>Features:<\/h3><p>Two electric motors ensure a uniform drive for the boring head.<br\/>The boring head is replaceable, so that the specified seat angle can be precisely maintained by selecting the appropriate boring head. <br\/>By turning the valve seat, a perfect concentric sealing surface for the valve is created.<br\/>Roundness, concentricity, seat angle, and surface quality of the turned valve seat comply with the specifications of the engine manufacturers.<\/p><p> <\/p><h3>Handling:<\/h3><p><b>Setup is very simple.<br\/><\/b>Clamp pilots with the mounted support cross into the valve guide. Place the machine onto the pilot and position the cutting tip of the turning tool in front of the inner edge of the valve seat.<br\/>Set the depth of cut using the finely graduated feed scale. Turning is performed automatically. At the push of a button, the valve seat is turned from the inside out at the specified seat angle.<\/p><p> <\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\n<\/div>\n<div class=\"elementor-element
