Coolant flow (AD/B)

For Internal Coolant Supply (IK) through the spindle we offer different solutions:    
Form A              without IK ( = external coolant supply)        
                           pull studs with or without bore can be used.      
Form AD            IK central through spindle        
                           Use pullstuds with bore           
Form B              IK through bores over collar        
Use pullstuds without bore        
Form AD/B         combined version        
IK either central or over the collar possible        
                            Use pullstud as mentioned above           
The coolant bores for Form B are sealed with plastic dowel and screw, which can be removed if needed.               
Do not re-use dowel and screw after taking them out of bore.
