Compliment your tool collection with RYOBI Diamond Grit Coated Technology. The 5 PC. 2" Impact Drive Bits include Diamond Grit Coated Technology. The Diamond Grit Coated Technology provides an additional layer of protection for 20X longer life, improving the bit durability across all Phillips screw driving applications. Diamond Grit produces a 2X stronger grip which allows for a strong pre-driving hold and seating of the fastener into the bit. This added grip creates a similar experience as a magnetically charged bit, but with a more secure hold. The Diamond Grit Coated Technology grabs into the Phillips fastener during driving applications for better fitment to prevent stripping of the Phillips head. This set is a perfect drive bit solution for all DIYers and Pros looking for less stripped screw frustration, and optimal pre-drive control. These 5 PC. 2" Impact Drive Bits are compatible with standard drills and impact drivers and include (5) 2" Diamond PH2 Bits.
