The DEWALT Impact Ready 6 in. Magnetic Locking Bit Holder provides users exactly what they need when fastening or drilling with hex-shank accessories. The bit holder's locking mechanism securely keeps the accessory in place during use and the quick-change features makes it easy to change accessories on the job. Robust magnetism provides optimal fastener retention for screwdriving applications. The magnetic locking bit holder's durable, uniquely designed locking mechanism allows users to not only drive with screwdriving bits, but accept all hex-shank accessories. 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.
