48-89-4613 Shockwave Impact-duty Titanium Drill Bit, 1/4 In.

The Milwaukee Shockwave Impact-Duty Titanium Drill Bit is a 1/4 inch diameter twist flute bit engineered for both standard drilling and impact applications. The titanium coating provides exceptional durability and extends bit life up to 3 times longer than black oxide drill bits, making it an economical choice for contractors and DIYers who demand reliable performance across repeated drilling tasks.

This bit solves the common problem of premature dulling and heat buildup during extended use. The variable helix design—with an aggressive 35-degree helix angle that transitions to 15 degrees—rapidly removes chips and limits heat accumulation, helping the bit stay sharper longer. The 135-degree split point tip delivers a precision start without walking, enabling fast and accurate hole placement in metal and other materials.

Features and Benefits

• Impact-Duty Titanium Coating: Delivers up to 3X longer life compared to black oxide bits and resists wear through repeated drilling cycles.
• Variable Helix Design: The aggressive 35-degree angle at the flute transitions to 15 degrees, optimizing chip flow for rapid removal and reduced heat buildup.
• 135-Degree Split Point Tip: Provides a precise, self-centering start that prevents bit walking and ensures fast, accurate hole placement.
• Extended Sharpness: Stays sharp through repeated use, delivering consistent drilling performance and reliable results on every job.
• Versatile Applications: Works in all drilling applications with both standard drills and impact tools.
