What Stands Out
High-Speed Steel
Crafted from high-speed steel, these drill bits ensure longevity and better heat resistance, making them ideal for tough materials and extended drilling sessions.
Extended Length
With a 12-inch overall length, these bits provide deep hole drilling capabilities, allowing for usage in thicker workpieces and hard-to-reach areas.
Black Oxide Finish
The black oxide coating enhances durability and reduces friction, leading to smoother drilling and a longer lifespan while resisting rust and corrosion.
