DeWalt Impact Ready locking bit holders provide users exactly what they need when fastening or drilling with hex-shank accessories. The locking mechanism securely keeps the accessory in place during use and the quick-change feature makes it easy to change accessories on the job. Robust magnetism provides optimal fastener retention for screwdriving applications and the durable, uniquely designed locking mechanism allows users to not only drive with 1 In. screwdriving bit, but accept all hex-shank accessories, making these holders accept 2 In. bits and longer, as well as hex-shank drill bits. The slim profile allows users to complete more applications than bulkier, competitive designs like countersinking screws in brackets or when installing fasteners in close quarters.
