The EXOPRO Mega Muscle drill is the world's first 3-flute drill for steels. Patented geometry permits stable chip ejection, even with less chip pocket space inherent in 3-flute drills. The result is up to 3X faster than 2-flute drills and up to 3X longer life.  

Features & Benefits:

• OSG's WD1 Nano Coating Technology: Higher coating oxidation temp & hardness dramatically improve wear resistance
• Patented Flute Geometry: Breaks steel chips into small manageable pieces for easy ejection
• Triple coolant ports: Optimum coolant delivered to cutting edges for longer life and smooth chip evacuation
