1.350in Spring Seat Cutter

The 1.350in Spring Seat Cutter by Comp Cams is a precision tool designed for engine builders and performance mechanics engaged in cylinder head work. This specialized cutter is essential for reconditioning valve spring seats to meet OEM and aftermarket specifications, making it invaluable for those upgrading camshaft packages or rebuilding high-mileage heads.

With a cutting diameter of 1.350 inches, this tool allows for precise depth control and surface finish, which are critical when matching seat profiles to both OEM and competition valve springs. Comp Cams' engineering ensures that the cutter produces concentric, properly angled seats that prevent rocking and binding under dynamic load, a common issue with poorly reconditioned heads.

Professional engine shops, experienced home builders, and powertrain rebuild specialists rely on this cutter for restoring or upgrading heads across both domestic and imported engines. Its compact and lightweight design enhances handling during extended machining sessions while maintaining the rigidity necessary for accurate cuts.
