Congratulations on the purchase of your 

Darex 

XT-3000

 Countersink Attachment. This fixture 

comes with 2 V-40 double angle collets and is 
used in conjunction with the 

Darex XT-3000

 X-Y 

Attachment.  

By now you are familiar with the ‘quick disconnect’ 
feature of your 

XT-3000

. Begin by removing the 

current sharpening 
fixture and replacing it 
with the X-Y table. 
Secure it in place by 
rotating the ‘Docking 
Lever’ clockwise. In a 
similar manner, lock 
the Countersink 
Attachment to the top 
of the machine.  

 

It is now necessary to 
determine the shank 
diameter of the tool that will 
be sharpened and place the 
corresponding collet into the 
Countersink Attachment.  
 
To do so 
slowly rotate 
the spindle 
clockwise until 
the Spindle 
Lock engages 
the spindle. 

Now unscrew the 
Draw Tube assembly. 
Place the correct collet 
in the end of the Draw 
Tube and replace the 
Draw Tube assembly 
and tighten 3 or 4 
revolutions. Should 
you need a collet size other than the ones 
provided, you may order them from Darex 
Corporation. (1-800-547-0222) 
 
Slide the cutting tool 
into the spindle leaving 
approximately 1” or 
more of the tool 
exposed. Loosen the 
Alignment Thumb 
Screw and rotate the 
Alignment Arm 
assembly around until 
the dowel pin 
intersects both the 
cutting edge and the 
heel simultaneously.  
 
 
 
Tighten the Alignment 
Thumb Screw.  Rotate 
the Draw tube 
assembly clockwise to 
tighten the tool in the 
spindle. Return the 
Alignment Arm to its 
original position and 
release the spindle lock 
pin by pulling up and 
turning the pin 90°. 
The cutting tool is now 
oriented to the spindle 
cam and is ready to be 
sharpened.
