Product Details: These aren't your average drill bits. The titanium coating on these high-speed steel bits means exceptional durability and longevity -up to six times longer than standard bits. This translates to less time spent replacing worn-out tools and more time focusing on what matters: keeping your fleet moving. The precise sizes (5/64", 7/64", 5/32", 1/4", and 19/64") are ideal for a wide range of applications, from general repair to specialized tasks. The left-hand spiral design is specifically engineered for removing stripped fasteners, a common problem in demanding fleet operations. This unique feature eliminates the frustration and wasted time associated with struggling to extract broken bolts or screws. The 135-degree split point on the larger bits provides effortless starts and prevents bit walking, ensuring clean, precise holes every time.
