Split Point Icon 

There are 3 split options with the XPS-16+. They are:

Tip:

 If the user wishes to only split the drill and skip the sharpening funtion, turn off the hone 

and point style icons by pressing both until an “X” comes across the image.

The XPS-16+ can be used as a 

HONE ONLY

 machine. This is accomplished by deactivating 

the 

[SHARPEN ICON]

 and the 

[SPLIT ICON]

. This feature is beneficial for new carbide 

drills that have not received a cutting edge treatment. Hone times vary depending on the drill 

size and the type of hone being used. When using the provided Silicone Carbide Hone, use 6, 

12 & 18 seconds for small, medium and large drill bits respectively. If using a Diamond Hone 

(option), reduce those times by 50% for the different drill sizes.

Tip:

 Honing the cutting edge of a carbide drill prolongs drill life and results in better hole-size 

consistency between sharpening.

Tip:

 A longer hone time produces a larger cutting edge radius. Trial and error is needed to 

determine the best cutting edge radius for each individual drill application. Factory default is 1 

second for each mode.

Drill Style Icon
