MZG Fast Drilling System
MZG present a detailed introduction to our comprehensive Fast Drilling System. This system represents a paradigm shift from conventional drilling, moving away from slow, solid HSS or brazed carbide drills towards a highly efficient, indexable insert-based methodology. It is engineered to dramatically increase metal removal rates, reduce operational costs, and enhance safety and precision across a vast spectrum of hole-making applications, from shallow holes in general manufacturing to deep, large-diameter bores in heavy industry.

Extreme Drilling Efficiency
Dramatically increase metal removal rates through advanced indexable insert technology with optimized geometries supporting high speeds and feeds compared to traditional solid drills.
Superior Chip Control & Evacuation
Advanced chip-breaking geometries with central coolant holes ensure efficient chip evacuation from deep holes, preventing chip packing and eliminating hazardous stringers.
Outstanding Cost-Effectiveness
Indexable design eliminates tool regrinding costs - simply replace low-cost inserts in seconds while maintaining consistent performance and minimizing machine downtime.
System Performance Analysis
The performance of our Fast Drilling System is defined by its exceptional speed, versatility, and intelligent design, which translates directly into superior productivity and hole quality. The core of the system, our U-Drills (WC, SP, SO, XO, WD, TAF series), are built for speed. By utilizing small, tough carbide inserts with advanced geometries and coatings, these drills can operate at significantly higher speeds and feeds than traditional twist drills.
A critical performance feature across the entire system is advanced chip control. Inserts are designed with sophisticated chip-breaking geometries that produce small, manageable chips. This, combined with the universal feature of central coolant holes in the drill bodies, ensures efficient chip evacuation even from deep holes. This prevents chip packing, reduces cutting forces, and eliminates the long, hazardous "stringers" associated with twist drills.
For deep-hole applications where the length-to-diameter (L/D) ratio exceeds 5xD, the Spade Drill is the superior performance choice. Its self-centering point geometry and balanced, dual-edge design ensure exceptional hole straightness and stability over long reaches. For machining extremely large diameters, the VMD system delivers unmatched performance with its modular design and replaceable components.
