APPLICATIONS
& Many More
Born alongside the rise of diesel-powered tractors and large-scale farming equipment, Jarvis has been a trusted partner to the agriculture industry since the 1940s. Trusted by OEMs like John Deere and Caterpillar, we engineer precision taps that meet the rugged demands of agricultural powertrains, frames, and hydraulic systems—delivering tool life, consistency, and confidence in every cycle.
It started in 1940’s, when Jarvis began producing high-speed steel taps for the heavy equipment sector, supplying the manufacturers behind the John Deere Model R and other groundbreaking machines. Since then, we’ve evolved alongside the industry—designing and manufacturing application-specific taps that can handle abrasive cast irons, alloy steels, and large-diameter threads common in drivetrain and structural components. Whether it’s a wheel spindle, engine block, or transmission housing, Jarvis taps are engineered to perform at scale and hold tight tolerances, even under extreme machining conditions.
At Jarvis, we understand that agricultural equipment demands more than just durability—it demands dependability in high-load, high-volume environments. That’s why we collaborate directly with your engineering teams to develop tap solutions optimized for the full system—from toolholding and coolant delivery to hole preparation and thread engagement. We help you reduce cycle time, eliminate rework, and achieve reliable thread quality across every part.

BEYOND TAPS
We create value by delivering more than just cutting tools. Our expertise, technical insight, and long-term support make us a trusted partner on your manufacturing floor.
In the agriculture industry, where uptime and reliability are critical, Jarvis engineers taps for the entire machining system. We optimize toolholding, machine setup, hole preparation, and coatings to ensure consistent performance across castings and forgings. Our expertise in cast iron, alloy steels, and welded assemblies helps reduce tap breakage, improve chip control, and extend tool life in high-torque applications.
We’ve earned our reputation as a tap specialist and long-term partner to OEMs like Cummins and Caterpillar, supporting them with large, high-performance taps built for heavy-duty applications. That same level of precision and reliability is available to you—whether you’re tapping engine blocks, CAT parts, structural frames, or transmission housings, we know what it takes to perform under pressure.
From global OEMs to contract manufacturers, we bring this same level of technical engagement to every customer. Our support includes on-site training for machinists and engineers on tapping fundamentals, thread tolerancing, and large-diameter tap application. We track tool performance, analyze thread quality, and provide data-driven recommendations to improve productivity and reduce scrap. Whether you’re tapping new designs or legacy equipment, our goal remains the same: optimize performance through precision and partnership.
