Bearing type or guide is vital for controlling the bit’s path and preventing damage to finished surfaces. Non-marring or ultra-glide ball bearings protect workpieces and ensure smooth operation, while different bearing sizes can match specific bowl slopes or templates. For example, the 49/64" Sink and Trim Bit Amana Tool 57155 features an ultra-glide ball bearing, perfect for smooth trimming, and the 2-9/64" Undermount Bowl Bit Amana Tool 57267 uses a bearing matched to its 10° draft. Multiple bearing options are available to suit various applications and preferences.
