But the drills make horrible gear grinding sounds now, and power no longer gets to the chuck. Eventually, all gears are affected.
Just need to be a little tougher. I used to own a commercial cabinet shop and must have heavy-duty tools, as I demand a lot from them.
I have used three of the Makita BDF451s in my home furniture and cabinet business for three years now, and they are great drills to use. The problem starts with 3rd gear (gears slipping, popping out of gear).
I concur with what others have said about power, balance, the very helpful light, quick charge time, etc. But now, two of the three drills have developed transmission problems.
The motors run just as powerfully as the day I bought them, and battery endurance is likewise still great. I would give 5 stars if Makita made a tougher transmission.
The BDF451 is NOT a hammer drill. Amazon is using the specs for the BHP451 which is in fact a hammer drill.
I had the last generation Makita driver/drill and really enjoyed it, but the new ones are significantly improved. Solid driver action and long lasting battery. Charger is high quality with a built in cooling fan (the last gen charger would not recharge back-to-back without a cooling perios).Ratchet could use a slightly higher level, but overall I'm completely satisfied.
The Makitas will go all day and dont need to be charged until i get home at night. Wow.it's sooo much lighter.I tested a new 18v Milwaukee Lithium-Ion drill. 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. It is very light, compact, powerful and has the basics onboard.like a drive tip clip, a belt loop, and lights.
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. The Dewalt did the same thing on occasion. Overall i am pretty pleased with this unit. I prefer this drill over the hammer drill version as it is a tad lighter and smaller (the chuck is a little shorter). The thing is a beast and is a pleasure to use but the size and weight of that thing is bigger than the Dewalt.
It is almost perfect. To a point that i had to keep a Dewalt charger in the truck to keep me going. I keep a hammer drill in the truck and had no need for duplication.for something i only need 3-4 times a month. The power is rated very high (torque) and have had only a couple of occasions where it bogged driving 4" screws.
I have a small home improvement business and needed a replacement for my aging (and battery eating) Dewalt 18v Ni-Cad drill. No thanks. It is not worth it.As far as the drill operation itself. Who cares. That little bit makes a difference when you are slinging these things around all day. Strangely, the Dewalt, which is rated lower, drove the screws the rest of the way. This is my first Lithium Ion tool and i am amazed mainly at how fast the batteries recharge.
I might have had the torque/speed setting wrong on the Makita.who knows.Overall.i would recommend it to anyone.homeowner or contractor. Folks seem to automatically buy the hammer version but look at the size and weight before you do it. And compared to the Dewalt. I had two of them and they both did it.
The speed change switch sticks on 2 when going between 1 and 3 or 3 to 1Don't Waste your moneyMakita say's this is normal.
