Milwaukee 48-89-2301 Red Helix Cobalt Drill Bit, 1/16 In., 2 In. Length

The Milwaukee 48-89-2301 RED HELIX Cobalt Drill Bit is engineered for extreme durability and long life in hard metal applications. This jobber-length twist drill is designed to handle demanding drilling tasks with precision and reliability, making it suitable for both professional and DIY use.

Milwaukee's RED HELIX design combines a variable helix angle with a reinforced core to address common drilling challenges like bit breakage, walking, and premature dulling. The aggressive 35-degree helix that transitions to 15 degrees promotes rapid chip removal, limiting heat buildup and keeping the bit sharper longer. This cobalt construction provides up to 10 times the life of standard black oxide drill bits.

Features and Benefits

• Variable Helix Design: The aggressive 35-degree helix that transitions to 15 degrees promotes rapid chip evacuation, reducing heat buildup and extending bit life.
• 135° Split Point Tip: The precision split point design ensures a clean entry without walking, delivering fast and accurate holes.
• Reinforced Core: A thicker web design provides ultimate strength, protecting against side-load breakage and enhancing flute durability.
• Cobalt Material: High-quality cobalt steel provides exceptional strength for long-lasting performance in hard metal applications and all twist drilling applications.
• Two-Flute Twist Design: The standard 2-flute jobber bit delivers effective drilling performance across a range of applications.
