Monaghan Tooling Group Elevates Threading Performance with New Vergnano H-Series Solid Carbide Taps

Monaghan Tooling Group has introduced the Vergnano H-Series, a new line of high-performance solid carbide machine taps engineered to tackle the most demanding threading applications. Designed for use in hardened steel, nonferrous metals, and superalloys, these taps deliver exceptional tool life, thread quality, and cutting speed, making them ideal for industries where precision and reliability are critical.

Crafted from premium micrograin carbide, the Vergnano H-Series taps incorporate advanced geometries and specialized coatings that enhance durability and cutting efficiency, even in challenging materials. With size ranges from 3 mm to 16 mm (0.118″ to 0.63″), the series covers both blind hole and through-hole operations, offering six distinct tap families optimized for various materials and threading requirements.

Among the lineup:

• The HB29 tap is a general-purpose cutting tool for blind holes in medium to long-chipping materials such as cast iron and aluminum alloys, available in 3–10 mm sizes.
• The HB43 and HB45 taps are high-performance tools with through-coolant channels, suited for 3–16 mm blind hole tapping in short-chipping materials like cast aluminum and cast iron, ensuring superior chip evacuation and performance.
• The HB80 is a cold forming tap with oil grooves, ideal for both blind and through holes in alloy steels and similarly tough materials, offering a chip-free threading solution.
• The HB81, designed for fine pitch threading, is also a cold forming tap with oil grooves, covering 8–16 mm applications in mild steel, stainless steel, aluminum alloys, and nickel-based alloys.
• The H130 is purpose-built for medium-chipping materials like hardened steel, available in 3–12 mm sizes for both blind and through-hole operations.

These taps enable faster cutting speeds without compromising thread quality or part integrity, crucial for components used in aerospace, automotive, heavy equipment, agricultural, and general manufacturing applications. Their versatility across hole types and material groups simplifies tool selection while ensuring maximum productivity and process reliability.

With the launch of the H-Series, Monaghan Tooling Group continues to support advanced manufacturing with cutting tools that meet the growing demand for high-precision, high-efficiency threading solutions across critical industries.
