Notes:
1.) M style milling heads are recommended for heavier duty milling and drilling applications.
      They incorporate two preloaded angular contact bearings on the front of the spindle for improved
      performance and durability in side load applications.
      D style drilling heads are smaller and may fit where M style heads will not. M style heads are the
      preferred choice where space permits.

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