Are Forming Taps More Expensive Than Cutting Taps?

Short answer: yes, forming taps usually cost 15–30% more at the checkout​ — but on a per-hole basis they are almost always cheaper in production. The sticker price is not the story; total cost per threaded hole is.
What the shelf price looks like
For an M10×1.5 HSS-E tap, a spiral-flute cutting tap typically runs $35, while a comparable forming (extrusion) tap sits around $45​ — about 28% higher upfront. For smaller sizes like M6, the gap narrows: a cutting tap may be $18 vs. $26 for forming, roughly 44% more for the forming tool, though absolute dollars are small. On B2B platforms, entry-level HSS forming taps start near $0.75/pc at volume, spiral-flute cutting taps $1.50–$8 depending on coating — so the "forming is pricier" rule holds across tiers, but the spread compresses at scale.
Why the math flips on the shop floor
Forming taps have no cutting edges to dull. In ductile materials they commonly last 3–20× longer​ than cutting taps:
•Aluminum: 500 holes (cutting) → 5,000+ (forming), 10×
•Brass/copper: 800 → 4,000+, 5×
•Mild steel: 300 → 1,500+, 5×
Take the M6-in-1018-steel example: cutting tap $18 / 1,500 holes = $12.00 per 1,000 holes​ in tooling; forming tap $26 / 12,000 holes = $2.17 per 1,000 holes. Add tool-change downtime at $4 per change and the totals become $14.70 (cutting) vs. $2.50 (forming) per 1,000 holes. Over a 100,000-hole run, that is $1,220 saved​ before counting scrap from chip jams.
A Balax customer on a Tormach center went from 200 holes/tap to 2,000+ after switching to forming on aluminum — and reported a 73% drop in annual threading tool spend​ despite buying pricier taps. In a deep-blind-hole case study, extrusion taps hit 40× the life​ of cutting taps and cut per-part cost by ≥50%.
When cutting taps still win
•Brittle materials: cast iron, hardened steel, brittle plastics — forming cracks them.
•Low-volume / job-shop mixes: setup discipline (tight drill-tolerance, EP fluid, higher torque) isn't worth it for ones-and-twos.
•Large threads above ~1″: torque demand makes forming impractical.
Bottom line for buyers
If you run ductile material, decent volume, and a rigid CNC, forming taps are the cheaper tool even at a higher unit price — often 5–10× lower cost per hole. If you're a distributor stocking for general job shops, cutting taps stay the default for flexibility; forming taps are the upsell for high-volume aluminum/copper/mild-steel customers who care about cost-per-hole, not cost-per-tap.
