Hitachi Power Tools has expanded its line of diamond-grit drill bits with four new sizes: 1/2-inch, 5/8-inch, 3/4- inch and 1-inch. They are designed to power through class 5 tile, marble, porcelain, granite, slate and glass quickly, outperforming standard carbide glass and tile bits in speed and volume.
Hitachi diamond-grit drill bit bodies are constructed of hardened and tempered thin-wall alloy steel. Required water lubrication can be applied with a spray bottle, producing a small puddle of water that is spiral-fed down the reverse flute threads onto the bit to continuously supply water to the cutting edge, cooling the bit tip and extending its life.
Hitachi Power Tools has also announced a new series of cordless drills powered by 1.5Ah lithium ion batteries that can be recharged 1,500 times before replacement.
The DFL series includes an 18-volt (DS18DFL) and a 14.4-volt (DS14DFL) drill. They feature two-piece magnet motors and deliver 374 inch/pounds (DS18DFL) and 274 inch/pounds (DS- 12DFL) of torque to push through the toughest jobs with ease. Both come with two 1.5Ah batteries. They maintain a steady charge from the moment the trigger is pulled until they need to be recharged. The battery technology reduces the weight by approximately a pound per tool.
A unique charger from Hitachi will charge 7.2-volt up to 18-volt lithium ion batteries. The proprietary technology in the universal charger provides Hitachi lithium ion batteries with overload and discharge protection so they won’t overheat or lose power. Batteries charge in 30 minutes.
