The Simpson 1/4 in. x 12 in. Straight Shank Carbide-Tipped Drill Bit is a premium, professional-grade tool engineered by Simpson to meet the precise tolerance requirements of demanding drilling applications. Built to the highest industry standards, this carbide-tipped masonry and concrete drill bit combines an advanced steel alloy body with proprietary manufacturing features that deliver faster drilling, longer service life, and dependable performance across a wide range of drilling tasks.

Key Features

• Uniformly brazed carbide inserts - provide consistent cutting edge integrity across the full life of the bit, meaning fewer replacements and more reliable performance job after job
• Centering tip design - facilitates easy spot drilling so the bit stays on target from the first contact, reducing slippage and improving accuracy
• Chromium-nickel-molybdenum steel alloy body - ensures hammering quality and extended service life, giving the bit the toughness to hold up under repeated impact and heavy use
• Heat-treatment procedures and shot-peened finish - increase surface hardness, drilling speed, reduce drill bit wear, and improve resistance to bending forces, so the bit performs faster and lasts longer under stress
• Conforms to ANSI Standard B212.15 - confirms the bit meets established industry requirements for performance and dimensional consistency, giving professionals confidence in the tool's reliability
• Straight shank design - ensures broad compatibility with standard drill chucks, making this bit easy to integrate into existing tool setups without adapters
• 10 in. drilling depth on a 12 in. overall length - provides the reach needed for deeper anchoring and fastening applications while maintaining control and stability

Why This Product

• Professional-grade construction built to tight tolerances - the combination of a chromium-nickel-molybdenum alloy body, uniformly brazed carbide inserts, and a shot-peened finish means this bit is engineered specifically to handle demanding drilling conditions where durability and precision both matter
• Faster, more accurate drilling from the first hole - the centering tip reduces wandering at startup and the heat-treated surface hardness promotes higher drilling speeds, helping crews work more efficiently without sacrificing hole quality
• Designed and manufactured to a verified industry standard - conformance to ANSI Standard B212.15 means buyers are not relying on manufacturer claims alone, but on a recognized benchmark for drill bit performance and dimensional accuracy
• Extended reach for deeper anchoring applications - with 10 in. of usable drilling depth, this 1/4 in. carbide-tipped bit handles applications that shorter bits simply cannot reach, making it a practical choice for structural fastening, anchor installation, and through-material drilling
