For increased durability, DeWALT built the new IMPACT READY™ drill bits with a unique, one-piece shank design. The integral design helps to reduce the occurrence of bit breakage, which is a common occurrence with bits that have two-piece designs. A patented tapered web design provides added strength in high-torque applications. The improved durability allows users to complete more applications using an impact driver including drilling holes into sheet metal, stainless steel, steel studs and junction boxes.
Let's face it, in a perfect world, galvanizing steel poles will provide a good level of protection against corrosion and pole failure. Unfortunately, this is an imperfect world. Before the pole leaves the factory, scratches, dents and ding will quickly compromise the zinc galvanizing and lead to pre-mature failure.
