1" Reduced Shank Black Oxide Drill Bit (1/2" Shank - DeWALT

The DeWALT DW1629 1" Reduced Shank Black Oxide Drill Bit is engineered for professional performance in demanding automotive and industrial applications. Designed for durability and precision, this high-speed steel bit features a specialized coating and flute geometry to optimize drilling efficiency in both metal and wood. Its reduced shank design ensures broad compatibility with standard 1/2" chuck drills.

Key Features

• 135-Degree Split Point: Enables immediate, precise drilling on contact, reducing bit "walking" and improving hole accuracy from the start.
• Parabolic Flute Design with 31-Degree Helix: Optimizes chip ejection for cleaner holes and faster material removal in diverse materials like metal and wood, balancing aggressive cutting with extended tool life.
• Black Oxide Coating: Enhances wear resistance and lubricity, contributing to a longer bit lifespan and consistent performance under rigorous use.
• Reduced 1" Cutting Diameter with 1/2" Shank: Provides a large cutting capacity while maintaining compatibility with common 1/2-inch drill chucks found on most professional-grade hand-held drills and drill presses.
• High-Speed Steel (HSS) Construction: Ensures robust performance and resilience for repeated use in tough materials.
