 Notes:
 Milling heads are
 recommended for heavier
 duty milling applications.
 They incorporate two
 preloaded angular contact
 bearings on the front of
 the spindle for improved
 performance and durability
 in side load applications.
 Drilling heads are more
 compact.

 2. "Taperlock and "Eltool"
 Spindles are proprietary
 spindles designed to
 minimize the profile of the
 angle heads.

 3. Please specify the size
 of Weldon spindle when
 ordering.
