  • Enhanced Durability - Diablo's Dura-Carbide technology offers up to 2X more carbide, enduring up to 1800°F. This significantly enhances durability by resisting intense heat and rebar impact that typically cause standard bits to fail at 800°F.
  • Superior Impact Resistance - The Carbide Head ensures controlled, consistent carbide wear and reduced vibration. This design allows for smaller, more manageable rebar extractions, delivering fast and precise holes even under extreme conditions.
  • Advanced Weld Strength—Equipped with Tri-Metal Fusion Welding, the bits feature a weld that is up to 3X stronger. This weld maintains the integrity of the full carbide head during severe impacts, such as hitting rebar, and prevents premature breakage.
  • Optimized Flute Design - The flute design enhances dust removal, which keeps the carbide head cooler and prolongs its strength and durability. This results in faster and efficient drilling, preserving the bit's sharpness and structural integrity.
  • Precision and Consistency - The precision tip of the bits ensures stable and accurate drilling, crucial for creating precise holes quickly in reinforced concrete for anchor setting.


Diablo’s revolutionary, complete range of SDS-Max Rebar Demon 4-cutter full-carbide head hammer bits are the first full line of bits designed to be the strongest, most durable, and fastest solutions on the market. Diablo’s ultra-hardened, full-carbide head bits withstand the stress of high powered hammer drills and the impact of rebar cutting, delivering extreme durability and strength. Produced with Tri-Metal Diffusion Bonding technology, the full-carbide head resists heat and prevents breakage for maximum life and productivity. Precision Tip delivers the stability and accuracy required to produce fast, precise holes in concrete with rebar for ANSI approved anchor setting. Diablo hammer bits are optimized for maximum performance in corded and cordless SDS Plus and SDS Max rotary hammers.

Those 4-cutter heads chew through concrete/stone very fast and hold up for a very good length of time.
