Diablo 3/4" x 37" x 39" SDS-Plus 2-Cutter Carbide-Tipped Hammer Drill Bit is engineered for professionals who demand fast, accurate holes in concrete and masonry. Diablo's signature Dura-Carbide construction and precision Peak Point Tip deliver aggressive starts and clean, consistent results - making this SDS-Plus bit a go-to choice for anchor installation and heavy-duty rotary hammer drilling applications. With a 39" overall length and 37" working length, this bit reaches deep into structural concrete and block work where shorter bits simply cannot perform.

Key Features

• Diablo Dura-Carbide construction - withstands high impact and elevated heat during drilling, dramatically extending service life compared to standard hammer drill bits so users replace bits less often and stay productive longer
• Peak Point Tip design - enables aggressive starts that produce clean, fast holes, reducing bit walking and delivering precise hole placement for common anchor sizes
• Optimized brazing and hardening process - secures and strengthens the carbide tips at a molecular level, extending tip life and increasing overall drilling productivity on tough concrete and brick surfaces
• Optimized four-flute design - removes concrete dust faster from the bore, keeping carbide tips cooler during extended use for ultimate strength and long-term durability
• SDS-Plus shank - compatible with both corded and cordless SDS-Plus rotary hammers, giving users flexibility across job site tool setups without adapters or modifications
• 39" overall length with 37" working length - accesses deep anchor points and long-run bore holes in thick concrete walls or block construction where standard-length bits fall short
• 2-cutter carbide-tipped head - balances cutting aggression and bit stability to produce accurate, clean holes with consistent diameter throughout the full working length

Why This Product

• Contractors drilling anchor holes in concrete or brick/block need a bit that stays sharp under repeated impact - the Dura-Carbide tip and specialized hardening process directly address premature wear that slows down jobs and increases bit replacement costs.
• The 37" working length is purpose-built for through-wall drilling and deep anchor applications that would require multiple passes or extensions with a shorter bit - this bit reaches the full depth in one setup.
• Made in Germany to tight tolerances, this bit delivers hole accuracy critical for anchor alignment and load-rated fastener installation in concrete and masonry.
• Optimized for both corded and cordless SDS-Plus rotary hammers, this bit transitions seamlessly between tool platforms - reducing downtime when switching between power sources on site.

Frequently Asked Questions

What materials can this Diablo SDS-Plus hammer drill bit drill through?

This bit is designed to drill through concrete and brick/block. The Dura-Carbide tips and Peak Point Tip design make it suitable for anchor hole drilling and general rotary hammer work in masonry materials.

Is this bit compatible with cordless SDS-Plus rotary hammers, or only corded tools?

This bit is optimized for maximum performance in both corded and cordless SDS-Plus rotary hammers, making it versatile across a wide range of job site tool setups.

What is the difference between the overall length and the working length on this bit?

The overall length is 39", which is the total length of the bit including the SDS-Plus shank. The working length is 37", which represents the usable drilling depth the bit can achieve once seated in the hammer chuck.

Why does the four-flute design matter for concrete drilling performance?

The optimized four-flute design removes concrete dust from the hole faster than designs with fewer flutes. Faster dust evacuation keeps the carbide tips cooler during sustained drilling, which preserves tip sharpness and extends the overall service life of the bit.
