What is the minimum thread engagement for blind holes in aluminum?

For aluminum and other non-ferrous materials, 1.5× the nominal diameter of thread engagement is sufficient for most applications. For steel and stainless steel, 1.0× diameter is typically adequate. Always verify against your engineering requirements.

Should I use a forming tap for blind holes?

Forming (roll) taps are not recommended for blind holes because they require 40–60% more torque and generate significant radial force that can deform thin-walled features. Use cutting taps with spiral flute geometry for blind hole applications.

How do I program chip breaking for blind hole tapping?

Use rigid tapping cycles with peck tapping if your CNC control supports it (G84.2 or M29). Otherwise, program a dwell at the bottom of the hole before reversal to allow chips to clear. Reduce tapping speed by 20% for blind holes deeper than 2× diameter. ⚡ Calculated for Carbide-Tooling.com High-Performance Series. View Catalog →
