ENGINEERED FOR STAINLESS: THE ULTIMATE HARD METAL DRILLING SOLUTION

Heat is the primary cause of bit failure when drilling through high-tensile materials like stainless steel and cast iron. These Cobalt RED HELIX bits are mechanically engineered to mitigate thermal breakdown through a sophisticated variable helix geometry. By transitioning from an aggressive 35 angle to a 15 exit, the bit achieves Rapid Chip Removal, preventing the material re-cutting that leads to friction-induced dulling. For the professional demanding long-term ROI, the cobalt infusion provides the structural integrity needed to outlast standard black oxide bits by 10X in the most punishing metalworking environments.

• / 135 Split Point Tip: Delivers a precision start on contact and eliminates bit walking, even on curved or uneven surfaces.
• / Variable RED HELIX Design: Optimizes chip ejection to reduce heat soak and maintain a sharper cutting edge for longer durations.
• / Chip Breaker Technology: Integrated into the cutting edge to break up large metal shavings, reducing friction and tool stress.
• / 3-Flat Secure-Grip Shank: Provides three flat contact points to ensure the bit remains locked in the chuck under high-torque drilling.
