Full CNC-Milled Single Iron — PGM TIG039 — Fully Milled, Black Finish, Four Shaft Options | FairwayWise
The PGM TIG039 is a premium CNC-milled iron with a black finish, sold as a single club. Four shaft options — graphite S, SR, R, or steel.
The CNC milling runs across the entire head, not just the face. The black finish is non-glare matte, similar to the look that boutique CNC brand and premium iron brand charge $800-1,300 per set for. This is the top-tier single iron in the PGM lineup.
CNC-milled irons are rare at any price. Most irons are cast or forged, then finished by hand.
A fully CNC-milled head — like the boutique CNC-milled blade that reviewers call “undeniably buttery” — is machined from a single block of metal, giving you tighter tolerances and more consistent weighting than either casting or forging. The TIG039 brings that manufacturing approach to a single-club price. If you want to experience what a fully machined iron feels like without buying a $800 set, this is how you do it.

Full CNC — Why Machining Matters More Than Forging
Forged irons get the glory. But CNC milling — cutting a clubhead from a solid block of metal — produces tighter tolerances than either forging or casting. Weight is more precisely distributed.
Faces are more consistently flat. The boutique CNC-milled blade, a fully CNC-milled iron that reviewers compare favorably to $1,600 sets, is built this way for exactly these reasons. The TIG039 applies the same manufacturing logic at the single-club level.
The black matte finish reduces glare at address. Same thinking as premium iron brand’s limited-edition black chrome ZXi7. The look is clean, modern, and — fair warning — it will show wear marks on the face and sole with use. Black finishes scratch.
That’s the trade-off for the look. The performance doesn’t change. The cosmetics do. If you want a finish that hides wear, buy satin chrome. If you want the blacked-out look and accept the patina it develops, this is your iron.
But here’s the thing. Four shaft options — graphite S, SR, R, and steel — give you more fit flexibility than any other iron in the PGM lineup. Most single irons offer one or two shafts.
The TIG039 offers four. Dial in the flex that matches your swing speed. That shaft optionality is worth more to your score than any head material or finish.
Frequently Asked Questions
Q1: What does “full CNC-milled” mean vs forged or cast?
A: The clubhead is cut from a solid block of metal by a computer-controlled machine. Every surface — face, cavity, sole — is machined to tighter tolerances than forging (heated and pressed) or casting (poured into a mold). Weight distribution is more precise.
Face flatness is more consistent. boutique CNC brand uses the same process for their $799 iron sets that reviewers call “buttery. “.
Q2: Will the black finish scratch?
A: Yes. All black/dark finishes show wear marks on the face and sole.
DBM (Diamonized Black Metal) finishes are more durable, but even those scratch over time. It’s cosmetic. The grooves, the CNC precision, the performance — none of that changes.
Q3: Which shaft should I choose with four options available?
A: Graphite R for slower swings (under 85 mph driver speed). Graphite SR for moderate tempos.
Graphite S for faster swings (95+ mph). Steel for traditional feel and maximum feedback. The graphite options reduce vibration and fatigue.
Q4: Is a CNC-milled iron forgiving enough, or is this only for scratch golfers?
A: The TIG039 is a precision tool — it rewards center strikes with excellent feel and consistency. It won’t bail you out on mishits the way a wide-sole cavity-back will.
Mid-to-low handicappers (under 15) who find the center of the face most of the time will appreciate what CNC precision brings. Higher handicappers should start with the TIG040 or TIG036 — more forgiveness, less punishment.
