The Simpson SDS-Plus Drill Bit 3/4 in. x 24 in. 2-Cutter Carbide-Tipped is a professional-grade rotary hammer bit engineered for demanding concrete drilling applications where reach, precision, and durability are non-negotiable. Built by Simpson to conform to ANSI Standard B212.15 and manufactured to the highest industry standards, this bit pairs an SDS-plus shank with a chromium-nickel-molybdenum steel alloy body and a uniformly brazed carbide 2-cutter head, making it a dependable choice for anchoring, through-drilling, and structural fastening work in concrete and masonry.

Key Features

• Uniformly brazed carbide inserts - consistent bonding across the entire cutting tip prevents premature tip loss and extends overall bit life compared to unevenly brazed alternatives
• Centering tip design - facilitates easy spot drilling so the bit stays on target from the first strike, reducing wasted effort and misaligned holes
• Chromium-nickel-molybdenum steel alloy body - delivers the toughness needed to absorb repeated hammer blows while maintaining structural integrity across an extended service life
• Heat-treatment procedures and shot-peened finish - increase surface hardness and drilling speed, reduce drill bit wear, and improve resistance to bending forces so the bit holds up under heavy rotary hammer use
• ANSI Standard B212.15 compliance - ensures the bit meets established dimensional and performance tolerances, giving buyers confidence in fit and interchangeability with compatible SDS-plus rotary hammers
• Chisel-shaped 2-cutter drill-bit head - penetrates material aggressively and directs concrete dust into the multi-flute spiral, keeping the cutting zone clear for faster, more efficient drilling
• High-volume, multi-flute spiral - quickly channels concrete dust from the hole back toward the surface, reducing clogging and maintaining drilling speed throughout deep passes
• SDS-plus shank - allows secure, tool-free bit installation and removal in any compatible SDS-plus rotary hammer or rotohammer, minimizing downtime between tasks
• 22 in. drilling depth on a 24 in. overall length - provides exceptional reach for deep anchor installations and through-slab applications while keeping the shank fully seated in the tool chuck

Why This Product

• Built for deep, heavy-duty concrete work - the 22 in. drilling depth and 3/4 in. diameter make this bit well-suited for large-diameter anchor installations, deep through-drilling, and structural applications where shorter bits simply cannot reach
• Premium materials engineered for longevity - the combination of a chromium-nickel-molybdenum alloy body, uniformly brazed carbide inserts, and a heat-treated, shot-peened finish means fewer bit replacements and more consistent performance across high-demand jobsite conditions
• Faster drilling with less downtime - the chisel-shaped 2-cutter head and high-volume multi-flute spiral work together to clear concrete dust continuously, so drilling speed stays high and the operator spends less time clearing holes between placements
• Part of a complete Simpson drilling system - this bit is one piece of a full line of premium carbide-tipped drill bits, core bits, and chisels from Simpson, allowing contractors to source compatible tooling for a wide range of drilling and demolition needs under a single trusted brand

Frequently Asked Questions

What type of shank does the MDPL07524 use, and which rotary hammers is it compatible with?

The MDPL07524 features an SDS-plus shank, which is the industry-standard connection system for SDS-plus rotary hammers and rotohammers. This shank type allows for quick, tool-free bit installation and removal while providing a secure, wobble-free fit during operation.

What is the difference between the overall length and the drilling depth of this bit?

The MDPL07524 has an overall length of 24 in. and a maximum drilling depth of 22 in. The 2-inch difference accounts for the portion of the bit that remains inside the tool chuck during use, ensuring the SDS-plus shank is properly seated in the rotary hammer.

What makes the carbide inserts on this drill bit last longer than standard bits?

The MDPL07524 features uniformly brazed carbide inserts, which ensure consistent bonding and tip stability throughout the bit's service life. Combined with the chromium-nickel-molybdenum steel alloy body and heat-treatment procedures with a shot-peened finish, the bit achieves increased surface hardness, reduced wear, and improved resistance to bending forces.

How does the drill bit manage concrete dust during drilling?

The chisel-shaped drill-bit head is designed to penetrate the material and direct concrete dust directly into the multi-flute spiral. The high-volume, multi-flute spiral then quickly channels that dust up and out of the hole, keeping the cutting zone clear to improve drilling speed and efficiency.
