Description of Diablo Freud DMAPL4320 SDS Plus 4 Cutter
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 three row brick wall to install an antifreeze for a hose. It punched through and didn't rip out the brick like a solid carbide drill would otherwise. I also like the security the rebar drill provides when drilling through material with unknown rebar or duralumin. This is my move to Beats now and the price just makes sense.
