  • Electronic Level – Digital readout for quick, accurate adjustment.
  • Depth Indicator – Shows the operator exactly how much has been removed from the seat assuring consistent seat depth. Also useful for installing seat rings, reducing valve guides, facing spring seats, etc.
  • Adjustable Depth Stop
  • Dual Speed Spindle Feed – Large handwheel provides rapid feed and small handwheel allows precise fine feed control of the spindle. Very helpful when depth of cut must be maintained to extreme levels of accuracy.
  • 15 Degrees Tilt – Spindle tilts up to 15 degrees from vertical in both directions , providing quick alignment on all canted valve cylinder heads. Cuts each seat to the exact same depth – a must for today’s computer controlled engines.
  • Spindle Nut – Offers quick tooling change for a wide selection of tooling and spindle adapters.
  • Rottler Patented Tooling – Rottler’s patented SG tooling totally eliminates any bounce springs. The quick change spherical spindle adapter allows different tool holders to be changed in a few seconds, change from multi angle seat cutting to pocket boring or reaming in just a few seconds! When the collar is moved down it aligns the tool holder vertically to allow the tool holder to be easily lowered down over the fixed pilot. While the tool holder is being lowered, the collar is lifted to release the sphere for precision centering and cutting. One hand pilot removal wrench allows fixed pilots to be moved from guide to guide – fast and easily.
