Robert Bosch Tool Group DDMS40 40-piece Drill Driver Set

Product Description

The ROBERT BOSCH TOOL GROUP DDMS40 is a 40-piece Impact Tough Drill Driver Custom Care System Set designed for trade professionals who need a reliable, organized bit solution on the job. The set includes a full range of insert bits, 2-inch power bits, and black oxide drill bits, all housed in a tilt-in/tilt-out storage case that keeps the right bit accessible at all times. Both driver and drill bits are impact rated, with a heat-treated manufacturing process for added strength. The X-Tended Torsion Zone on driver bits absorbs high torque from impact drivers, extending service life compared to standard impact bits.

This set is suited for residential and commercial installation work including HVAC rough-in, electrical rough-in, plumbing fixture work, and general construction tasks. It covers the most common drive types encountered in trade applications: Phillips, Robertson (square), Torx, and combination profiles, plus a graduated selection of black oxide drill bits from 1/16 inch through 1/4 inch. The customized case configuration keeps bits sorted and reduces time spent searching for the correct size during a service call or rough-in job.

Key Features

• Impact-rated driver and drill bits for longer service life than standard impact bits
• X-Tended Torsion Zone absorbs high torque generated by impact drivers
• Black oxide coating on drill bits reduces friction and heat buildup
• Precision-engineered driver bit tips for tighter fit and reduced cam-out
• Heat-treated bit construction for increased strength
• Tilt-in/tilt-out case mechanism with customized storage layout for fast bit access

Compatibility

Designed for use with standard 1/4-inch hex chuck impact drivers, drill/drivers, and power screwdrivers commonly used in HVAC, electrical, plumbing, and general trade applications.

Installation Notes

Insert bits and power bits are intended for use with power tools only — confirm the tool chuck is rated for 1/4-inch hex shank accessories before use. Inspect bits for wear or deformation before each use, and replace any bit that shows cracking or rounding at the tip. Store the set in the provided case to prevent bit loss and protect tips from damage.
