air vents. Wear approved eye protection
and approved dust mask when
performing thisprocedure.

chemicals may weaken the materials

(DCH143, DCH243, DCH253, DCH273).
Special SDS Plus
®
adaptors with threaded
sections are available for use with standard
10 or 13 mm chucks to enable straight shank
bits to beused.
