DEWALTDW5401B25 DeWalt 5/32" x 4-1/2" x 6-1/2" Rock Carbide™ SDS+ Hammer Bit (Bulk 25)

I drill alot into concrete and I pay quite a bit for dewalt and bosch SDS Hammer Bits. and the store i shop at dont do bulk buy so i cant get a good price. so i looked on here and found these for an amazing price. Obviously too good to be true. these bits last me maybe 5-6 holes before completely flatten out and start to burn. waste of money.

Drilled over 30 holes with a single bit Keep it cool and drill straight. Works great!

Great value

I've been laying sleepers down on concrete and burning through these like crazy. They seem to overheat easily. I think the solution is to avoid overheating them by 1) pre-drill the wooden sleeper, 2) don't push down on the drill, 3) suck the dust out as your drilling.

I used to be able to get a 25 pack of Makita concrete bits on here. 1 Makita bit would outlast 10 of these DeWalt ones easily. I'm a deWalt guy over Makita tonsonthats saying allot. These bits are garbage.

Great product.

Good deal
