Metal Tapping Services

OSH Cut offers metal thread tapping up to 1.5" in diameter, in steel, stainless, aluminum, copper, brass, and bronze.


Save Time and Headache

Avoid the time, headache, and potential for broken taps by letting us cut threads in your part.

OSH Cut offers metal tapping in tap sizes ranging from 6-32 to 1 1/2-6 (standard) and M3 x 0.5 to M36 - 4.0 (Metric). Our equipment makes metal tapping fast and cost-effective.

Select Tapping After Upload

Our instant quoting app automatically detects circular holes in your flat pattern or 3D model. To add tapping to your part, simply select the appropriate holes in your drawing after upload, and choose the tap size.

We'll automatically adjust the hole size as needed to accommodate the tap size that you selected. We report the adjusted hole size and target thread engagement / thread depth we used to calculate it, and the number of threads that will be cut in your selected material thickness.

Thread Pricing

Pricing depends on part size and tap size. For common taps, pricing starts at less than $10 for a single hole, with additional tapped holes costing as little as 10 cents each.

Most of the initial cost for tapping stems from setup and fixturing time for each part, so a part with many threaded holes costs much less for each hole beyond the first.

Large tapped holes tend to cost more because of higher consumable costs.
