The Ohio Broach & Machine Company provides comprehensive broaching solutions, from tool sharpening to machine manufacturing and high-volume production. Renowned for its precision, the company specializes in producing tightly toleranced parts, including broached lower receivers for the AR-15 rifle—components that meet exacting military specifications.
Advanced Broaching Techniques
With extensive experience supplying multiple manufacturers, Ohio Broach has refined its broaching process to ensure optimal accuracy. For AR-15 lower receivers, the company employs a two-pass broaching method.
The process begins with a forged aluminum part pre-machined with a starter hole, allowing the first broach tool to engage. Fixture clamps secure the workpiece, while additional supports prevent distortion during cutting. Guided broach tools then shape the receiver’s top, sides, bottom, and corners, delivering a finished part that meets all critical dimensional tolerances.
Specialized Machinery for Efficiency
Ohio Broach utilizes its proprietary HF1572 horizontal broach machine, equipped with 15 tons of cutting force and a 72-inch stroke. The machine features an automated hydraulic clamping system and a broach retriever, streamlining the operation. Once an operator loads the part and initiates the cycle, the fully automated process completes in approximately one minute, producing a finished lower receiver with a fully broached magazine well.
Industry-Leading Expertise
Since its founding in 1956, Ohio Broach has established itself as a trusted partner across industries, including automotive, aerospace, hand tools, and oil and gas. The company’s commitment to precision and efficiency continues to drive its reputation as a leader in broaching technology.
