High productive head-changeable drill

Stable performance, long tool life, and significant cost-savings are possible thanks to the elimination of tool reconditioning and reduced inventory

Applications & Features

Drilling

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

Inserts & Grades

Inserts

DMP (ø4.0 – ø25.9 mm)
