FAQ:

Q: What size drill bit for 5 16 18 tap?

A: Tap & Drill Bit 5/16 – 18. The set’s letter G bit attaches to standard chucks to drill holes with a 0.261-inch diameter. The Irwin high carbon steel tap relies on its high-strength composition to withstand tough jobs, and it delivers consistent results every time. This happens because the tap self-aligns without any special tools.

Q: How to size helicoil?

A: How to calculate the size of a helicoil drill? F is equal to the insert nominal length (Q) + ½ the nominal bolt diameter + 5 Pitch (allowing for tap chamfer, countersink and maximum “set-down”).

Q: Are helicoil taps special?

A: Fixing Stripped Threads The components of a Helicoil kit are the inserts, a special tap and the installer too. You need to provide the drill bit for most kits.
