Helicoil M8x1.25 STI Tap

This Helicoil 2087-8 straight flute hand tap cuts M8 by 1.25 metric coarse threads for screw thread inserts. It is made from high speed steel with a bright uncoated finish and a right hand thread direction. The plug chamfer and four flutes suit through holes and general purpose threading work.

Machinists repairing damaged threads

Technicians who need to create internal threads for Helicoil inserts will find this D9 limit tap matches the insert specification. It is not for cutting standard bolt threads without an insert, nor for left hand thread applications, and it does not suit blind holes that require a bottoming chamfer.

74.61 mm overall length with 31.75 mm thread length

The 74.61 mm overall length and 31.75 mm thread length determine whether the tap reaches the required depth in your workpiece. Verify these dimensions against your hole depth and fixture clearance before ordering.

Questions about this item

How much torque or heat builds up when running the M8×1.25 tap continuously through steel?

The tap is uncoated high-speed steel with a 31.75 mm thread length and four straight flutes; cutting fluid and proper speed keep heat low during extended use.

What holder or wrench does the 2087-8 tap need to operate?

It has a standard metric shank for an M8 tap wrench or T-handle; no proprietary driver is required.

Will this D9-limit plug tap cut threads that accept standard M8×1.25 bolts from older toolboxes?

Yes, the D9 limit produces a standard 6H-class internal thread compatible with existing metric coarse fasteners.
