2pcs M12 x 1.75mm / M14 x 2.0mm / M16 x 2.0mm Metric Tap High Speed Steel Thread Tap Metalworking

Label:Yes - THREE METRIC SIZES - This set covers three large-diameter metric sizes: M12 x 1.75mm(0.47 x 0.07in) pitch (drill 10.2mm(0.40in)), M14 x 2.0mm(0.55 x 0.08in) pitch (drill 12mm(0.47in)), and M16 x 2.0mm(0.63 x 0.08in) pitch (drill 14mm(0.55in)), addressing common coarse-thread requirements for general machinery and heavy equipment repair.

- 4 STRAIGHT FLUTES DESIGN - The four-flute configuration facilitates chip evacuation during the tapping process and delivers stable thread formation across steel, cast iron, and aluminum materials in both manual and machine-driven use on larger diameter threads. - ENGRAVED SIZE MARKING - Each tap shank features clear size engraving (such as M12X1.75) for quick identification without referring to packaging, reducing selection errors during workshop use. - TAPER AND PLUG TAP PAIR - Each size includes one taper tap for initial thread cutting and one plug tap for completing full-depth threading to specification, enabling two-pass tapping for clean and accurate internal threads on through-hole and blind-hole applications.

- ALLOY TOOL STEEL CONSTRUCTION - Each tap is made from hardened alloy tool steel with H2 tolerance grade, providing durable cutting performance on steel, cast iron, aluminum alloy, and brass workpieces for machining and equipment maintenance applications.

Specifications: Material: Alloy Tool Steel (Hardened) Flute Type: 4 Straight Flutes Tolerance Grade: H2 Thread Standard: Metric (ISO) Thread Direction: Right-Hand Finish: Polished / Black Oxide (varies by size) Shank Type: Square Drive End Size Marking: Engraved on Shank Color: Sliver

Size Options: - M12 x 1.75mm (Drill Diameter: 10.2mm / 0.40in) - M14 x 2.0mm (Drill Diameter: 12mm / 0.47in) - M16 x 2.0mm (Drill Diameter: 14mm / 0.55in)

Compatibility: Suitable for cutting internal threads in steel, mild steel, cast iron, copper, brass, aluminum alloy, and plastic materials. Compatible with tap wrenches, drill press chucks, CNC lathe tool holders, tapping heads, and handheld tapping fixtures. The taper-and-plug pairing supports both through-hole and blind-hole threading applications in machining workshops, equipment repair, mold making, agricultural machinery maintenance, and general metalworking tasks. Recommended for coarse-pitch (coarse thread) applications on machinery bases, mounting flanges, and structural fastening points.
