When off-the-shelf taps don’t meet your specific manufacturing requirements, Regal Cutting Tools provides an ultra-fast, highly accurate alternative. By utilizing semi-finished blanks, we can engineer and ship custom taps engineered to your exact specifications in as little as 24 hours.
Best for: Customers who require custom threading solutions that fit basic ANSI standards but need specialized features, thread forms, or pitch diameters.
Availability: Ships as early as next business day via our signature 24-Hour Custom Taps service. (Conditions do apply.)
A tap blank is a semi-finished unthreaded cutting tool that has been pre-machined to conform to ANSI (American National Standards Institute), DIN (Deutsches Institut fur Normung), JIS (Japanese Industrial Standard) or DIN/ANSI (DIN OAL ANSI Shank/Square) dimensions for overall length and holding (shank) specifications, but has not yet had its specific cutting threads or flutes ground.
By stocking thousands of high-quality blanks, we bypass the most time-consuming steps of tool manufacturing, allowing us to grind the specific thread characteristics you need and ship the finished product immediately.
Once the appropriate ANSI blank is selected, our engineers customize the cutting end based on your exact application needs:
Threads Per Inch (TPI) / Pitch
Custom spacing to match specialized fasteners or unique part designs.
Thread Form
We can grind standard 60-degree V-threads (UNC, UNF, UNEF), Metric profiles, ACME, Whitworth, coil, buttress, as well as a wide range of special thread profiles
Pitch Diameter Limits
Precision grinding to specific "H" limits (inch) or "D" limits (metric) to accommodate pre-plating, heat-treat shrinkage, or oversized/undersized hole conditions.
Chamfer Style
Taper, plug, or bottoming chamfers designed for your specific blind or through-hole applications.
Massive Size Range: Taps are manufactured up to 6″ in diameter daily.
High Volume Output: We process and manufacture up to 100 custom orders every single day for next-day shipment.
Regal pioneered the “24-Hour” shipment model for custom taps over six decades ago. Today, our streamlined processing and specialized grinding equipment remain unmatched by the competition. We understand that spindle downtime costs money, which is why 99% of customer orders for blank custom taps are shipped the very next day.
Thanks to our extensive inventory of ANSI-compliant blanks and streamlined grinding processes, 99% of custom tap orders are manufactured and shipped within 24-72 hours of order placement.
We routinely manufacture custom taps up to 6 inches in diameter. If you have needs beyond standard sizes, please contact our engineering team.
Yes. One of the primary advantages of modifying a tap blank is the ability to specify custom pitch diameter limits (H-limits or D-limits). This allows you to cut a slightly oversized or undersized thread to compensate for secondary finishing processes like anodizing, plating, or heat-treating.
We can grind nearly any thread form required, including standard Unified National (UNC/UNF), Metric, ACME, Trapezoidal, Pipe Threads (NPT/NPTF), and custom or proprietary profiles.
Absolutely. Because the shank and overall length adhere strictly to ANSI 302 and 303 standards, these custom tools will drop perfectly into your standard collets, tap chucks, and holders without the need for specialized tooling.
