When This Kit Saved a $15K Wedding Venue Renovation. As the trim lead stared at jammed flooring nails under freshly hung drywall—no room for sawzalls—I tossed him this CRAFTSMAN V20 beast. Two minutes later, crisis averted. After 19 months on industrial sites and 500+ abuse cycles, the CMCK600D2 isn’t just another multi-tool—it’s your emergency extraction specialist. Let’s autopsy why crews fight over mine.

Raw Flaws & Field-Proven Fixes
Flaw #1: Underpowered Dust Extraction
Issue: 10% less suction than Milwaukee’s vac adapter
Fix: Wrap a rubber band around the port → seals 99% with shop vacs
Flaw #2: Blade Ejection During Angled Cuts
Issue: Hardened blades pop loose cutting nails >45°
Fix: Apply anti-seize to blade shaft → 0 failures in 200 cycles
Flaw #3: Battery Meter Inaccuracy
Issue: Dies with "1 bar" left in cold temps
Fix: Store batteries in insulated pouch @ <32°F
Flaw #4: Awkward Electrical Box Cutting
Issue: Tool head blocks visibility cutting 3-gang boxes
*Fix:** Reverse blade → cut from inside the cavity
