The Panasonic EY75A7 impact driver is a dual voltage model, which means that it is compatible with both 18v and 14.4v Panasonic batteries. 

Improvements made over the previous model include a new “self-drilling screw mode”, improved durability, improved brushless motor, and a stylish new “carbon black” design. 

What Are The Key Features Of This 18v Panasonic Impact Driver?

• Tough Tool IP56 dust and splash protection means that you can use this tool in any conditions.
• Self-drilling screw mode: the tool starts at the highest speed to cut the hole, then transfers to “hard” (high-impact) mode to cut the thread. After that the load is reduced, so the tool switches to “soft” (soft-impact) mode to limit potential thread stripping.
• New brushless motor is more powerful, more compact, and more well-balanced. It will provide you with up to 200% more cycles, and has a thicker motor shaft to provide greater strength for heavy-duty use.
• Improved durability: see below for details.
• Improved drivetrain design reduces “centre run-out”, improves accuracy, reduces damage to the screw, and allows smoother driving with lower noise and vibration levels even during heavy usage.
• Hard, medium, and soft modes are ideal for fastening long bits and bolts, furniture, and plasterboard respectively.
• 3-speed provides even more application flexibility.
• Electric brake improves user and tool protection.
• Usability features include improved anti-slip grip pattern, belt hook, LED worklight, and tapered bit holder that enable quick and easy bit changes.
• Superb battery technology

What Improvements Have Been Made To Durability?

• Housing: metal plates have been added where the battery locks into the tool. This helps to prevent wear and tear caused by abrasion and vibration during heavy use.
• Anvil: the redesign and improvement of anvil materials has increased the durability of the impact parts, which ensures a longer service life and increased overall performance.
• Switch: the hybrid switch uses rigid metal parts in the trigger for 200% more durability compared to the previous switch model.
• Motor: thicker motor shaft (φ5mm) ensures greater strength, for heavy-duty use.
• Elastomer Bumper: increased amounts of rubber and resin coating on the bottom of the tool which help prevent damage if dropped from elevated areas.
