A New Drilling Concept!
0.5xD of spotting
Many drill manufacturers and suppliers state that their drills start drilling on the solid material.
You can look forward to the following benefits when using the NC Spot Drill to drill a spot that
is half of the drilling diameter.
Drill Benefits >>
• Higher feed rate.
Why? Because the drill is guided at the strongest part of cutting edge.
• Better center position.
Why? Because the spotting is done by a single cutting edge which is out of center,
and similar to boring operation.
• Increased tool life.
NC Spot Drill
• Better center
position!
• Longer tool life!
Without Spotting 0.5xD Spotting
• Drill has less position accuracy • Best result!
• Higher speed and feed rate.
• Better position accuracy and
and diameter tolerance.
Larger Spotting
• Longer spotting time!
• Guided at the weakest
corner of drill.
• Shorter tool life
diameter tolerance.
Unstable tool life
