Corded, 1 in. Rotary Hammers are suited for overhead drilling.
Press Release Summary:
February 27, 2014 - To increase accuracy, model HR2611F, and model HR2621 feature Anti-Vibration Technology (AVT®) internal counterbalance system. Both models deliver 2.1 lb-ft impact energy and offer 3 selectable modes of operation: rotation only, hammering with rotation, or chipping only. Other features include sequential impact timing, variable speed trigger, and 40 bit angle settings. While HR2621 has ergonomic D-shaped handle with rubberized soft grip, HR2611F has LED light at base of pistol grip.

MAKITA Adds Two New 1 Inch Rotary Hammers to Expanding AVT Line-Up
Press release date: February 18, 2014
La Mirada, CA – Makita has expanded its line-up of concrete hammers with two new 1” Rotary Hammers: model HR2611F (Pistol-Grip), and model HR2621 (D-Handle). Both feature Anti-Vibration Technology (AVT), an internal counterbalance system for significantly less vibration.
“Reducing vibration and increasing accuracy in smaller rotary hammers addresses a key user need on jobsites,” said Adam Livingston, Product Manager, Commercial Products, Makita USA. “A one-inch rotary hammer is frequently used for overhead drilling, and less vibration is strongly preferred for this type of application in order to help increase drilling accuracy. The new HR2611F and HR2621 with AVT meet this demand.”
The HR2611F and HR2621 are the latest additions to Makita’s line-up of concrete hammers equipped with AVT, including demolition hammers (70 lb., 42 lb., 27 lb.) and rotary hammers (2”, 1-3/4”, 1-9/16”, 1-1/4”). With the addition of the two new 1” AVT hammers, Makita now offers an AVT hammer solution in every hammer class.
Enhanced Anti-Vibration Technology
Makita AVT is an internal counterbalance system engineered inside the tool that greatly reduces vibration by moving a counterweight in the opposite direction of the drive piston. The new HR2611F and HR2621 feature a 2-component AVT system:
• With AVT, the same “wobble” bearing that moves the drive piston inside the tool also moves the counterweight (highlighted with arrow, right) in the opposite direction, thereby reducing vibration.
• An integrated damper spring at the base of the impact bolt is engineered to absorb impact vibrations from the drill bit.
Less Vibration, Increased Performance and Versatility
The new HR2611F (7 AMP) and HR2621 (8 AMP) Rotary Hammers both deliver 2.9 Joules (2.1 ft.lbs.) of impact energy to handle the most demanding applications. Both hammers offer 3-mode operation for “rotation only”, “hammering with rotation” or “chipping only” for multiple applications. Modes can be easily changed with a recessed hammer-function selector, which is located below the gear housing for improved durability.
Additional features in the HR2611F and HR2621 include sequential impact timing that delivers timed hammering during rotation to minimize overlapping bit impacts for up to 50% faster drilling. The variable speed trigger enables the user to match the speed to the application, and the 40 bit angle settings offer increased operating convenience. Both rotary hammers offer convenient one-handed bit changes for added convenience.
The HR2621 has an ergonomic D-shaped handle with a rubberized soft grip for increased operator comfort, as well as a retractable tool hook to secure the tool to studs, ladders, and rails when not in use. The HR2611F has an LED light at the base of the tool’s pistol grip to illuminate the work surface in low-light conditions.
The new HR2611F and HR2621 are engineered for a range of concrete applications including overhead drilling into concrete, wood and metal, removing tile, and more. They are ideal for a range of trades including masons, plumbers, electricians, sprinkler installers, city maintenance crews, and general contractors seeking a best-in-class 1” rotary hammer.
