The Milwaukee Tool 4-pc Cushion Grip Screwdriver Set, No. MT200-4, has custom machined screwdriver tips that are designed to deliver a precise fit and reduce stripping during demanding fastening applications. In addition, the tips are laser etched to increase the gripper surface and each screwdriver is made with high strength, boron-infused steel for increased hardness. Select screwdrivers include a wrench-ready bolster for added torque and a knurled shank for precision control. The screwdrivers also have identification markings on the handle which are intended to make it easier to identify tip size including Phillips, slotted, and cabinet tips. This set includes screwdrivers offered in 4" and 6" shank lengths.
