Straight Shank Drill Bit by Simpson is a premium carbide-tipped drilling tool engineered to meet precise tolerance requirements for professional masonry and concrete drilling applications. Designed and manufactured in Germany to the highest industry standards for Simpson Strong-Tie, this straight shank drill bit incorporates proprietary features that enhance durability and drilling speed while improving ease of use on the job site. Whether you are anchoring fasteners into concrete, masonry, or similar hard materials, this professional-grade bit delivers consistent, reliable performance across demanding installations.

Key Features

• Carbide-tipped cutting edge - provides exceptional hardness and wear resistance for faster, cleaner holes in concrete and masonry without premature dulling
• 1/4 in. straight shank diameter - compatible with standard drill chucks for quick, tool-free bit changes and versatile use across common drilling equipment
• 6 in. overall length with 4 in. drilling depth - reaches adequate depth for anchor installations without requiring an extension, reducing setup time
• Straight shank design - ensures secure chuck grip and minimizes bit slippage during high-torque drilling operations, improving accuracy and safety
• Manufactured in Germany to the highest industry standards - consistent tolerances from bit to bit mean predictable hole sizing for anchors and fasteners every time
• Proprietary design features for enhanced durability - extends service life under repeated use, lowering the cost per hole on larger projects

Why This Product

• Built specifically for Simpson Strong-Tie anchor systems, this drill bit is sized and toleranced to produce holes that align precisely with Simpson anchor specifications - reducing the guesswork of matching generic bits to fastener requirements
• German-manufactured to strict professional-grade quality standards, this carbide-tipped bit delivers the consistency that contractors and installers demand when drilling into concrete and masonry where hole quality directly affects anchor holding strength
• The straight shank configuration makes this bit immediately usable with standard keyless or keyed drill chucks already on the job site, without adapters or special equipment
• Proprietary features engineered for both speed and durability mean fewer bit replacements over time, making this an efficient choice for repetitive anchor installation work

Frequently Asked Questions

What type of chuck is compatible with this drill bit?

This drill bit features a 1/4 in. straight shank, which is compatible with standard keyless and keyed drill chucks commonly found on rotary drills and hammer drills. No adapters are required for most professional drilling equipment with a 1/4 in. or larger chuck capacity.

What is the maximum drilling depth this bit can achieve?

This bit is designed for a drilling depth of 4 in., with an overall length of 6 in. The additional length beyond the drilling depth accommodates chuck grip and helps ensure the bit remains secure during the full depth of the bore.

Is this drill bit suitable for use with Simpson Strong-Tie anchor systems?

Yes. This carbide-tipped drill bit is manufactured to meet the precise tolerance requirements specified for Simpson Strong-Tie anchor systems, making it a reliable choice when installing Simpson anchors into concrete and masonry substrates.

What makes carbide-tipped drill bits preferable for concrete and masonry applications?

Carbide tips are significantly harder than standard high-speed steel, allowing them to cut through abrasive materials like concrete and masonry without dulling quickly. This results in cleaner, more accurately sized holes and a longer usable bit life compared to non-carbide alternatives.
