What Size Drill Bit for 10 32 Tap

When preparing to tap a 10-32 thread, selecting the correct drill bit size is critical to achieve proper thread engagement and avoid tap breakage. You’ll want to use a 21/64 inch drill bit, as it provides the ideal minor diameter for clean, strong threads.

But what if that size isn’t available? Understanding why this precise dimension matters and how to adapt can save you time and prevent costly errors.
