Applications & Features
Applications
Features
1. Exchangeable head drills for unparalleled tool life and machining performance
– Helical margin to prevent chip adhesion between the body and the hole during machining
– Tool body made from highest grade of steel with superior hardness for high wear resistance
– Wide variety of geometries for every drilling application
– Advanced grade options ensure stable, long tool life
– Internal coolant channels supply efficient cooling and lubrication during the drilling process
2. Quick and precise head changing with advanced self-clamping system
– Drilling head pocket designed to withstand high machining cutting conditions
– Allows easy and fast head indexing, minimizing machine downtime
3. Ensures long tool life and wear predictability
Margin of DrillMeister head
– Cutting head is always new and reliable
– Optimized coating thickness provides long tool life
– Constant coating quality provides superior tool life predictability
Tool life fluctuations of DrillMeister
Margin of solid carbide drill (after reconditioning)
– Excess coating thickness due to multiple re-coating processes
– Fragile coating layer due to excess re-coating
– Result: unpredictable tool life
Tool life fluctuations of solid carbide drills
