• Stubby length design provides superior rigidity and reduced deflection
• 135° split point tip for self-centering and fast penetration
• Ideal for drilling stainless steel, titanium alloy, and hard sheet metal

• High-speed steel construction for durability and performance
• Made in USA by Tru-Cut Manufacturing

Stubby drill bits offer increased stability compared to jobber-length bits, making them less prone to walking or breaking when drilling through tough materials. The compact design is particularly useful in confined spaces where standard-length bits cannot reach. Each package contains 12 drill bits for professional or high-volume applications.
