Valve Lapping Tool Attachment 8mm Shank 4 Suction Plates

A valve lapping tool attachment for seating engine valves during cylinder head work and rebuilds. It has an 8mm shank, automatic reverse action and includes four suction plates to suit different valve sizes.

Used for valve seating work during engine servicing, rebuilds and general workshop maintenance, this attachment helps when refitting valves and working on cylinder heads. It is suited to mechanics, engine builders and capable DIY users carrying out repair work where a consistent lapping action is needed with fine grinding paste. The automatic change in direction helps keep the lapping process moving without constant manual adjustment, which is useful when working through multiple valves on the same head.

The supplied suction plates in 20mm, 30mm, 35mm and 45mm sizes give coverage across a range of common valve head sizes. An 8mm shaft allows the attachment to be fitted to suitable equipment, and the stated working speed of 1000rpm to 1250rpm max gives clear operating guidance for use. It is intended for use with fine grinding paste and can also be used with CT4429. Having four suction plate sizes in one set makes it easier to handle different jobs without needing separate attachments, which is useful for regular maintenance and repair work.
