Helicoil 2087-9 Straight Flute Hand Tap M9-1.25 Plug 4

Thread Repair Tap for M9 × 1.25 Holes

This Helicoil straight-flute hand tap cuts internal threads sized M9 with a 1.25 mm pitch. It is designed for technicians who need to create or restore metric coarse threads in steel, aluminium or cast iron using a standard tap wrench. The H5 thread limit provides a standard fit for general-purpose thread-insert installations.

Replaces Worn or Undersized Taps

A new tap restores clean, accurate thread geometry when an existing tap has dulled or when a drilled hole proves slightly undersized. The plug chamfer eases entry and reduces torque, making the step worthwhile whenever thread quality affects fastener holding power or when a damaged thread would otherwise require a larger insert size.

Fits Standard Tap Wrenches and Drill Schedules

The 74.00 mm overall length and 32.00 mm thread length match common M9 tap-drill charts, so the tool works with the drill bits already in a metric tap set. Four flutes clear chips efficiently in through-holes, while the bright high-speed steel finish resists galling without requiring special lubricants or powered tapping equipment.
