Description of π₯ Diablo Freud DMAPL4180 SDS Plus 4 Cutter: Supreme Performance for Effortless Drilling
Diablo made Dura-Carbide withstands impact and high heat applications, dramatically extending life versus standard hammer bits. Precision Tip delivers stability and accuracy required for fast, precise holes. Tri-Metal Diffusion Bonding provides heat resistance and prevents breakage of the full-carbide heat for maximum life and productivity. Optimized four-flute design removes dust faster, keeping the carbide head cooler for ultimate strength and durability.
I used this drill bit to drill through a 4" thick concrete slab with a pergola to attach a 6" x 6" anchor post for a pergola. It's a beast! Highly recommended. Drilled 16 holes in 4" rebar concrete and it went like a hot knife through butter with no sign of wear.
I used this DEWALT Hammer Drill Bit with Shock Absorbers, D-Handle, SDS, 1-1/8" (D25263K) and it drilled a 4" deep hole in it 30 seconds: something I couldn't do with a regular Dewalt hammer drill with a regular concrete drill in 20 minutes of idle drilling. With this product you can quickly drill holes in reinforced concrete.
