Titleist 718 T-MB Irons Review

Put on the map by Jordan Spieth’s miraculous recovery on the 13th hole during the final round of the Open Championship at Royal Birkdale, the new 718 T-MB iron is a technologically advanced distance muscleback.

Previously it was only available in 716 2 – 5-iron but now golfers can benefit from the performance in a full set.

The irons feature a hollow-back construction with a thin, unsupported L-Face insert that allows the face to flex more at impact, increasing launch and speed for more distance.


The most high-density tungsten in the Titleist 718 lineup – with an average of 93.9 grams precisely placed in the heel and toe – highlighted by the brown sections on the sole, optimises launch and spin to produce higher shots that go far and land soft.

This high-MOI design increases off-centre ball speed and accuracy for forgiveness while delivering stability and tour-validated feel. Improved leading edge pre-wear creates more efficient turf interaction for more consistent contact.

“T-MB is an absolute workhorse that launches high and just keeps going,” Josh Talge, Vice President of Marketing, Titleist Golf Clubs, told GM. “Players can’t believe the performance they get out of a club that from address looks like a classic muscle back.”

The Titleist 718 T-MB irons are available in 2-P, 50º with an RRP of £230 per club in the True Temper Project X PXi steel shaft, £255 per club in graphite. In addition, Titleist offers an industry-leading number of custom shaft choices.
