Makita BDF451 18 Volt Lithium Ion Driver Drill Kit Review

I have a small home improvement business and needed a replacement for my aging (and battery eating) Dewalt 18v Ni-Cad drill. Overall i am pretty pleased with this unit. It is very light, compact, powerful and has the basics onboard…like a drive tip clip, a belt loop, and lights. This is my first Lithium Ion tool and i am amazed mainly at how fast the batteries recharge. And I get a full day out of the two batteries in this kit as opposed to the Dewalt which would go through at least three before they ran down. To a point that i had to keep a Dewalt charger in the truck to keep me going. The Makitas will go all day and dont need to be charged until i get home at night.

Makita BDF451 Review – For You

I prefer this drill over the hammer drill version as it is a tad lighter and smaller (the chuck is a little shorter). I keep a hammer drill in the truck and had no need for duplication …for something i only need 3-4 times a month. 
Folks seem to automatically buy the hammer version but look at the size and weight before you do it. That little bit makes a difference when you are slinging these things around all day. And compared to the Dewalt? Wow…it’s sooo much lighter.

I tested a new 18v Milwaukee Lithium-Ion drill. The thing is a beast and is a pleasure to use but the size and weight of that thing is bigger than the Dewalt. No thanks. It is not worth it.

Some Complained

As far as the drill operation itself. It is almost perfect. Some have complained about the speed switch getting stuck at the top which has happened to me maybe 4 times in two months of daily use. Who cares. 
The Dewalt did the same thing on occasion. I had two of them and they both did it. 

The power is rated very high (torque) and have had only a couple of occasions where it bogged driving 4″ screws. Strangely, the Dewalt, which is rated lower, drove the screws the rest of the way. I might have had the torque/speed setting wrong on the Makita …who knows.
Overall…i would recommend it to anyone…homeowner or contractor.

Customer Reviews

Hammer Drill? – M. Boswell – 
The BDF451 is NOT a hammer drill… Amazon is using the specs for the BHP451 which is in fact a hammer drill.

Awesome tool – Barry Boudreau – El Dorado Hills, CA the USA
I had the last generation Makita driver/drill and I really enjoyed it, but the new ones are significantly improved. Solid driver action and a long-lasting battery. The charger is high quality with a built-in cooling fan (the last gen charger would not recharge back-to-back without a cooling period).

Ratchet could use a slightly higher level, but overall I’m completely satisfied…

Do not buy this drill – Carpenter – The speed change switch sticks on 2 when going between 1 and 3 or 3 to 1.
Don’t Waste your money-
