39-Piece Metric Thread Repair Kit

The ROTATION 39-piece metric tap and die set covers thread sizes from M3 to M12. It includes coarse and fine pitches such as M6x1.0, M8x1.25, M10x1.5 and M12x1.75. A 1/8NPT27 pipe tap is also supplied for basic plumbing work. The kit suits mechanics and DIY users who need to create or restore threads on site.

Metric and NPT limits only

Thread coverage stops at M12 and a single 1/8NPT27 size. Larger metric diameters, finer pitches or other pipe standards are not included. The set works on carbon steel, aluminium, copper, cast iron, brass and stainless steel. Users requiring threads beyond M12 or additional NPT sizes will need a separate kit.

HSS and chrome vanadium with double-layer case

Taps and dies are made from hardened high-speed steel and chrome vanadium steel for wear resistance. A quick-lock wrench, tap adapter and tap adapter bar simplify hand operation. An SAE thread pitch gauge and flathead screwdriver are included. The double-layer storage case keeps the 39 pieces organised and protected during transport.

Questions about this item

Should I choose the 39-piece metric set or the SAE version?

The 39-piece metric set covers thread sizes from M3 to M12 including coarse and fine pitches like M6x1.0 and M10x1.5, plus a 1/8NPT27 pipe tap; the SAE version uses inch-based sizes instead.

What does the HSS and CRV steel construction mean for thread quality in stainless steel?

Hardened high-speed steel and chrome vanadium steel provide the toughness and wear resistance needed to cut clean, precise threads in stainless steel without the taps or dies breaking.

Does the 1/8NPT27 pipe tap follow a standard that limits the pipe size I can thread?

The 1/8NPT27 tap follows the National Pipe Taper standard at 27 threads per inch, which is used specifically for 1/8-inch nominal pipe size fittings.
