Background and Identification
Makita Jack Hammer HM1812 is a corded electric breaker hammer or jackhammer manufactured in Japan. This model weighs about 69 pounds and can be used for breaking, chipping, and digging applications. This jackhammer can be used for landscaping, pool installation, plumbing, masonry, remodeling, and contracting, among other applications.
It includes a 15 Amp motor that delivers non-variable 870 blows per minute (BPM) and 53.9 foot-pounds (72.8 joules) of impact energy per blow. This jackhammer operates at 106 decibels, which is relatively quiet for comparable power breakers. The HM1812 model includes a 16.4-foot long cord. This model accepts 1-1/8 -inch Hex Bits and includes a cylindrical tool holder that enables the operator to re-position the assembly if the original bolts or bolt holes break.
The HM1812 model also includes anti-vibration technology (AVT) that reduces vibration and directs more impact energy to the work surface for increased productivity. It also features a soft-start function to suppress start-up reactions for operator safety and accuracy. The HM1812 model also includes an LED service/power indicator that indicates cord damage or a switch failure and alerts the user up to eight hours before the hammer’s brushes need to be replaced.
The Makita Jack Hammer HM1812 can be identified by its teal color and the name “Makita” in lowercase letters vertically along the main body of the machine. This model also includes the acronym “AVT,” which stands for anti-vibration technology, printed vertically in the middle of the main body of the hammer. It includes black handles on either side of its body and a 1-1/8-inch chuck attached to the main body.
