Hitachi DH28PFY SDS-Plus Rotary Hammer

Hitachi DH28PFY SDS-Plus Rotary Hammer

Hitachi has announced two new tools, adding to its growing concrete rotary hammers. The Hitachi DH28PFY SDS-Plus Rotary Hammer and its DH26PF brother are said to deliver higher durability thanks to three specific improvements. One is a hammering mechanism featuring an air channel system that reduces wear and damage inside the cylinder.

The second improvement is a ball bearing that supports the front end of the second shaft to prevent a shortage of grease and reduce the generation of heat that could damage the gear cover. The last is a new internal pressure control mechanism that provides smoother airflow.

Both the Hitachi DH28PFY SDS-Plus Rotary Hammer and DH26PF claim to deliver faster drilling speed due to the combination of Hitachi’s motor selection and enhanced hammering mechanisms.

The Hitachi DH26PF SDS Plus-Rotary Hammer features a 1-inch capacity with its 7.5-amp motor that produces 2.4 ft-lbs of impact energy while the Hitachi  DH28PFY SDS-Plus Rotary Hammer is a 1-1/8-inch model using an 8-amp motor that produces a little better impact energy at 2.5 ft-lbs.

Both tools offer no-load impact speeds of 0-1,100 RPM and impact rates of 0-4,300 IPM. The Hitachi DH28PFY SDS-Plus Rotary Hammer also features Hitachi’s patented User Vibration Protection (UVP) technology, which reduces vibration transfer to the user and can reduce the risk of developing a vibration-related injury due to prolonged exposure.

Both Hitachi DH26PF and DH28PFY SDS-Plus Rotary Hammers are equipped with “D” shaped rear handles for better control in overhead applications. Both tools deliver 3 standard modes of operation: drilling only, hammering only and hammer drilling along with an angle adjustment position.

More features include soft double-molded side handles for soft and easy grip and comfortable operation, a large change lever located on the side for easy operation, and one-push action for quick bit mounting. The new Hitachi DH26PF and DH28PFY SDS Plus Rotary Hammers come complete with a depth gauge, side handle and plastic carrying case.

The Bottom Line

The big difference between these two hammers is the Hitachi’s User Vibration Protection. You also get a little more muscle in the DH28PFY. The price difference for the additional ergonomic consideration and power is about $60, but worth it for the guy that’s going to be using it. Hitachi has been focusing more on the concrete side of the industry and we expect to see more, including continued expansion of their AC Brushless line of rotary hammers.
