Simpson 3/16 in. x 14 in. 2-Cutter Head SDS-Plus Drill Bit with Carbide Tip is a premium, professional-grade rotary hammer drill bit engineered for precise, high-speed drilling in concrete, masonry, and other hard materials. Built from hardened steel with a carbide-tipped cutting head, this bit is designed to meet demanding tolerance requirements while delivering exceptional drilling speed and extended tool life. The SDS-Plus shank offers tool-free bit changes and secure chuck engagement, making it a dependable choice for contractors and tradespeople who need reliable performance on the job site.

Key Features

• 3/16 in. diameter with 12 in. drilling depth - delivers clean, accurately sized anchor holes that meet the precise tolerances required for structural fastening applications
• Carbide-tipped 2-cutter head - provides aggressive material removal and long-lasting cutting performance in concrete, block, and masonry without premature wear
• SDS-Plus shank - locks securely into SDS-Plus rotary hammers for positive drive transmission and fast, tool-free bit swaps, reducing downtime on the job
• 14 in. overall length - adds reach in confined spaces and through-wall drilling situations where standard-length bits fall short
• Hardened steel construction - resists stress and flexing under the repeated impact loads of rotary hammer operation, extending working life
• Manufactured to the highest industry standards - incorporates proprietary features that enhance both durability and drilling speed, reducing operator fatigue and total drilling time
• Professional-grade quality from the Simpson Strong-Tie line - designed to satisfy the strict performance criteria demanded by structural installation work

Why This Product

• Precision-toleranced for structural anchor work - the 3/16 in. diameter is held to tight dimensional tolerances, which is critical when drilling holes for code-compliant anchoring systems where hole size directly affects load performance
• Extra-long 14 in. length reaches where standard bits cannot - the 14 in. overall length paired with a 12 in. drilling depth makes this bit practical for deep embedment anchors and through-wall applications that shorter bits cannot handle
• Broad SDS-Plus compatibility - the SDS-Plus shank format is the industry standard for rotary hammer drills, meaning this bit integrates immediately with the rotary hammers already on your job site
• Part of a complete Simpson Strong-Tie drilling system - designed alongside Simpson Strong-Tie anchors, fasteners, and accessories so the bit geometry and tolerances are matched to Simpson's anchor installation requirements

Frequently Asked Questions

What type of rotary hammer does this drill bit fit?

This bit uses an SDS-Plus shank, which is the most widely used rotary hammer chuck format in the industry. It is compatible with any rotary hammer or combination hammer drill that accepts the SDS-Plus (also called SDS+) shank standard.

What is the difference between the overall length and the drilling depth?

The overall length of this bit is 14 in., which includes the full shank and body. The drilling depth is 12 in., which is the maximum usable cutting length that can penetrate into the material. The difference accounts for the portion of the bit retained inside the chuck during drilling.

What does a 2-cutter head mean and how does it affect performance?

A 2-cutter head features two carbide cutting edges arranged at the tip of the bit. This configuration efficiently breaks up concrete and masonry material under rotary hammer impact, producing clean, consistently sized holes. The carbide tips are engineered for durability so the cutting edges maintain their geometry over extended use.

Is this drill bit suitable for drilling anchor holes in concrete?

Yes. The carbide-tipped 2-cutter head and SDS-Plus shank are designed specifically for rotary hammer use in concrete and masonry. The bit is manufactured to precise tolerance requirements, making it well-suited for drilling anchor holes where accurate hole diameter is necessary for proper anchor engagement and load performance.
