Features & Benefits

• Premium M42 Cobalt Bi-Metal Teeth. Engineered with M42 high-speed steel cutting teeth containing 8% cobalt for exceptional hardness and durability. The HRC65–68 hardened teeth deliver long-lasting cutting performance, superior wear resistance, and reduced tooth chipping.
  
  
• Ultra-Thin Wall Design for Faster Cutting. Featuring an ultra-thin 0.6mm cutting wall that minimizes resistance during drilling. The optimized design allows smoother cuts, faster penetration, and reduced power consumption for improved efficiency.
  
  
• Precision Multi-Tooth Cutting Geometry. Advanced alternating tooth configuration provides balanced cutting action, enhanced stability, and cleaner hole edges. The sharp, precision-ground teeth ensure fast, accurate hole making in various materials.
  
  
• Integrated Safety Stop Shoulder. Built-in stop shoulder helps control drilling depth and improves positioning accuracy. Achieve cleaner, more consistent holes with greater safety and ease of operation.
  
  
• Efficient Chip Ejection & Heat Dissipation. Large chip-removal slots promote rapid debris evacuation and effective cooling during operation. Reduced heat buildup helps prevent tooth temper loss and extends tool life during continuous use.
  
  
• Precision-Ground HSS Pilot Drill Bit. Equipped with a fully ground high-speed steel pilot bit for accurate centering and reliable positioning. Delivers improved drilling precision and long-term durability.
  
  
• Quick-Change Anti-Slip Hex Shank. The 1/4" hex shank enables fast accessory changes while providing a secure grip that resists slipping under load. Compatible with cordless drills, electric drills, and drill presses.
  
  
• Ideal for Electrical Installation Work. Designed specifically for electricians and maintenance professionals. Easily create clean, round holes in electrical cabinets, distribution boxes, control panels, cable trays, thin steel sheets, and plastic enclosures.
  
  
• Portable Storage Case Included. Comes with a compact folding storage case that keeps all components organized, protected, and easy to transport between job sites.
