Review on DEWALT DW1921 64 Inch Ferrous Oxide by David Venable

When I tried this bit, I was amazed by the clear, precise holes it created without any difficulties.The ferrous oxide coating prevents slipping and shockwaves. The strength and durability of this bit make it UNBEATABLE and it cuts quickly with little effort. The only downside is its price, but when it comes to industrial needs, it's worth the expense. Overall, its an optimal choice for heavy-duty usage..
