Bosch 18V EC SDS Plus Bulldog 1in Rotary Hammer Kit

Description

Cold morning overhead electrical conduit runs and suspended pipe hanging require light hammer tools that spare worker shoulders. The Bosch 18V EC Bulldog Hammer Kit punches 1-Inch holes in concrete using brushless motor power. You control trigger feathering by hand. This compact tool handles medium anchor holes, but it lacks the impact mass for heavy slab demolition.

Glass-filled nylon forms the ergonomic motor housing, reinforced with textured rubber overmold to grip securely in damp hands. A brushless EC motor connects to 18V lithium battery lines, driving an internal striker mechanism to deliver 4350 blows per minute and 1.9 foot-pounds of impact energy at 890 RPM. KickBack Control electronics halt motor rotation during rebar binds. The bare tool weighs 6.3 lbs, measuring 13.7 inches long for ceiling anchor installation.

Key Features of Bosch 18V EC

Electricians buy Bosch 18V EC Bulldog hammer kits to hang conduit and drill drop-in anchors without arm exhaustion. The brushless motor extends runtime while the lightweight chassis balances overhead in ceiling spaces.

• Efficient EC brushless motor delivers 1.9 foot-pounds of impact energy to drill fast anchor holes.
• Standard 1-Inch SDS-Plus capacity handles drop-in anchors, tapcons, and small conduit penetrations.
• KickBack Control sensor cuts motor power in a split second if the drill bit binds on rebar.
• Electronic precision control starts rotation at seventy percent power to prevent bit walking on smooth surfaces.
• Compact 7.7-lb loaded weight reduces shoulder and neck fatigue during overhead drilling passes.
• Integrated LED worklight illuminates dark mechanical rooms and drop-ceiling spaces.
• Vario-Lock positioning rotates chisels into multiple angles for light tile and mortar scraping.

Striker Impact Bench Load Metrics

Bench testing proves the pneumatic striker delivers 1.9 foot-pounds of impact energy at 4350 blows per minute under manual downfeed into 4000 PSI concrete. Drilling a 1/2-Inch solid carbide bit through 4-Inch concrete slabs takes an average of 14 seconds per hole. The KickBack Control electronic accelerometer trips within 0.15 seconds of sudden spindle lockup, limiting handle whip to under 12 degrees. Internal striker cylinder temperatures remain below 120 degrees Fahrenheit across 30-Minutes of anchor drilling on test stands.

Jobsite Handling Operational Field Limits

The balanced D-handle and rotating side grip give you solid two-hand control during overhead ceiling anchor drilling. Skip this light hammer for heavy demolition trenching or core drilling past 2-Inch diameter. The 1.9 foot-pound striker lacks the impact mass to chip thick foundation slabs or drive large rebar dowel bits. Apply a dab of chisel grease to bit shanks before working.

• Grease the SDS-Plus bit shanks with high-pressure grease before every work shift.
• Wipe concrete dust off the front rubber nose boot to prevent grit ingress into the chuck.
• Clear dust out of the battery connection terminals using clean compressed air each week.

Manufacturer Warranty Standard Kit Manifest

Bosch covers the 18V EC Bulldog hammer with a 1-Year limited warranty and a 3-Year battery pack warranty. The heavy kit box delivers the 1-inch rotary hammer, an 18V 4.0Ah battery, a fast charger, an auxiliary side handle, a depth stop rod, and an illustrated operator manual.
