Get the job done with this Milwaukee Shockwave 45pc Impact Driver Bit Set. Engineered to be the most durable, best fitting driver bits on the market, the Wear Guard Tip delivers increased wear resistance which protects the impact bit's fit over its lifespan. The Shockzone is optimized for each tip type and length of driver bit in the set to absorb peak torque and prevent breaking. For a customized steel and heat treatment per tip type to extend the life of the user's driver bits, the driver bits offer Custom Alloy76, providing up to 50 times life versus other impact driver bits on the market. The Milwaukee seven-piece Shockwave Red Helix Titanium Drill Bit Set is engineered for extreme durability and lasting use. To enable faster removal and less heat for longer bit life, the Quad Edge Tip provides a precision start and four cutting edges to create smaller chips. A variable helix offers an aggressive 35-degree helical angle that ends at 15 degrees. With Red Helix, these tapered drill bits provide rapid chip removal limiting heat buildup to stay sharper longer. An internal enhanced tapered web greatly improves their strength, reducing premature breakage. Perfect for many applications including but not limited to wood, plastics and metals, Milwaukee Red Helix Titanium Drill Bits deliver up to five times life when compared to black oxide drill bits.
