Is it risky to buy Cordless Drill from US online for use in Ireland?

Looking at purchasing an 18v Makita Cordless Drill
unsure as to whether a power adapter will work
Update: This Drill seems to be top of the range.
Makita BDF452HW 18 Volt Compact Lithium-Ion Driver Drill Kit.
Priced it in Ireland at €500, was looking at same spec Drill on, cost is $200 (€130 roughly). Have mailed supplier.
