Bosch DDMS20 Impact Tough 20-piece Drill Drive Set

Product Description

The ROBERT BOSCH TOOL GROUP DDMS20 is a 20-piece impact-rated drill and driver bit set packaged in a tilt-in/tilt-out case designed for trade use on jobsites. The set includes a full range of insert bits, 2-inch power bits, black oxide drill bits, and a standard bit holder. Driver bits feature an X-Tended Torsion Zone that absorbs the high torque output of impact drivers, extending bit life under heavy use. Precision-engineered tips deliver a tighter fit at the fastener head to reduce cam-out. Heat-treated construction and high-visibility bit markings round out the core design.

This set is suited for electricians, HVAC technicians, plumbers, and general trade contractors who need a compact, organized drill and driver solution on the bench or in the field. The customized storage configuration keeps individual bits accessible without digging through a pouch or loose case. The black oxide coating on the drill bits reduces friction and heat buildup during drilling, which extends bit life in repetitive-use applications.

Key Features

• Impact-rated driver and drill bits with X-Tended Torsion Zone to absorb impact driver torque
• Precision-engineered driver bit tips reduce cam-out and improve fastener engagement
• Black oxide drill bits with lower-friction coating for reduced heat and longer life
• Heat-treated bit manufacturing for increased strength under load
• Tilt-in/tilt-out case mechanism for quick, easy bit access
• High-visibility bit markings allow fast bit identification on the job
• Customized internal storage keeps the correct bit at hand at all times

Compatibility

Designed for use with standard 1/4-inch hex-drive impact drivers and drill/drivers commonly used in residential and commercial trade applications.

Installation Notes

Insert bits and power bits are compatible with any 1/4-inch hex chuck; confirm chuck type before use. When using impact-rated bits in a standard drill, do not exceed the drill manufacturer's recommended torque settings. Store bits in the provided case to prevent tip damage and keep the set complete between jobs.
