• [2 Taps & 1 Die Set]: M18 x 2.5 metric, right hand. Includes 1 taper tap (starter tap for first stage threading, long chamfer for easy start), 1 plug tap (for blind/through holes, covers the function of a bottom tap), and 1 round die (for external thread cutting & repair). Perfect for creating new threads or fixing worn/stripped metric threads
• [Specification ]: M18-2.5 tap & die are manufactured strictly to metric thread specifications, achieving 6H internal thread precision / 6g external thread precision to ensure accurate thread profile and fit. Tap: Overall length 89mm, thread cutting length 42mm, shank diameter 14mm, square drive 11.2mm, square length 14mm. Die: outer diameter 45mm and thickness 18mm. Complete dimensions ensure perfect fit with standard tap wrenches and die stocks
• [Material]: 18x2.5 tap and die set is crafted from 9SiCr alloy tool steel — outperforming ordinary bearing steel and carbon steel. Cutting edge hardened to 60-63HRC for sharpness, wear resistance, and anti-chipping. Shank maintains 45-50HRC for torsion strength. This hardness-gradient design significantly reduces tap breaking and tooth chipping risk during manual operation
• [Application]: 18mm x 2.5 tap die works on low-carbon steel, aluminum, brass, cast iron, and hard plastics. Widely applied in automotive repair, mechanical maintenance, plumbing renovation, farm machinery repair, mold processing, workshop production and household DIY projects. Ideal for professional maintenance workers, technicians and DIY enthusiasts to solve various metric thread problems
• [Pro Tips for M18 2.5]: Hand use only. Straight flute design allows downward chip evacuation for through holes and blind holes. Recommended pre-drill hole size: 15.5mm(0.6102"). Always use tapping oil/cutting fluid for better thread quality. Tapping depth ≤ 1.5x tap diameter. Die works best with proper die stock (not included)
