The Simpson 5/8 in. x 18 in. SDS-Plus Drill Bit with 2-Cutter Carbide Tip is a premium, professional-grade rotary hammer bit engineered for demanding drilling applications in concrete, masonry, and similar hard materials. Built to the highest industry standards, this bit delivers the precision, durability, and speed that contractors and construction professionals require when boring 5/8 in. diameter holes up to 16 in. deep.

Key Features

• Uniformly brazed carbide inserts - maintain a secure, consistent bond between the carbide tip and the steel body, resulting in longer bit life and fewer replacements on the job.
• Centering tip - facilitates easy spot drilling so the bit locates and starts holes accurately without walking or slipping, saving time and reducing material waste.
• Chromium-nickel-molybdenum steel alloy body - ensures superior hammering quality and extended service life under the repeated impact of heavy rotary hammer use.
• Heat-treatment procedures and shot-peened finish - increase surface hardness and drilling speed, reduce bit wear, and improve resistance to bending forces, keeping the bit performing reliably through tough applications.
• Chisel-shaped 2-cutter drill-bit head - penetrates concrete and masonry efficiently and directs concrete dust into the multi-flute spiral, reducing clogging and maintaining cutting performance.
• High-volume, multi-flute spiral - quickly channels concrete dust out of the hole, improving drilling speed and reducing the need to repeatedly withdraw the bit to clear debris.
• Conforms to ANSI Standard B212.15 - ensures consistent dimensional accuracy and interoperability across all compatible SDS-plus rotary hammer tools.

Why This Product

• Professional-grade construction built for real job site demands - the combination of a chromium-nickel-molybdenum alloy body, uniformly brazed carbide inserts, and heat-treated, shot-peened finish gives this rotary hammer bit the structural integrity and wear resistance required for repeated heavy-duty concrete and masonry drilling.
• Faster drilling with less interruption - the chisel-shaped 2-cutter head and high-volume multi-flute spiral work together to penetrate hard materials quickly and evacuate concrete dust efficiently, keeping holes clear and reducing downtime between passes.
• Trusted Simpson engineering in a precision-made tool - this bit is part of Simpson Strong-Tie's complete line of premium drilling accessories, manufactured to the highest industry standards and designed with proprietary features that enhance durability and ease of use across professional anchoring and construction applications.
• Broad compatibility with standard SDS-plus rotary hammers - the SDS-plus shank fits all SDS-plus rotary hammer tools, allowing for secure, tool-free bit changes and making this bit a reliable fit for professionals who work with a range of compatible equipment.

Frequently Asked Questions

What type of rotary hammer is this drill bit compatible with?

This drill bit features an SDS-plus shank, which fits all SDS-plus rotary hammers. The SDS-plus shank design allows for secure, tool-free bit changes on any compatible SDS-plus rotary hammer tool.

What are the key dimensions of this drill bit?

This drill bit has a diameter of 5/8 in., an overall length of 18 in., and a maximum drilling depth of 16 in.

What materials and construction methods are used to ensure durability?

The bit body is made from a chromium-nickel-molybdenum steel alloy for superior hammering quality and extended service life. The carbide inserts are uniformly brazed for a consistent, secure bond that extends bit life. Heat-treatment procedures and a shot-peened finish increase surface hardness, reduce wear, improve drilling speed, and enhance resistance to bending forces.

Does this drill bit meet any industry standards?

Yes, this drill bit conforms to ANSI Standard B212.15, which ensures consistent dimensional accuracy and interoperability across compatible rotary hammer tools.
