Q: What size is the pilot bit

a month ago
1 Answer
  • A: Howdy neighbor! The pilot bit included with this Mibro hole saw kit features a standard 1/4-inch diameter to help center your cuts perfectly. The bit sits inside a mandrel that has a 3/8-inch shank, meaning it will fit securely into any standard 3/8-inch or 1/2-inch drill chuck.

Didn’t even drill through sheet metal once before the mandrel stripped out and teeth dulling.

No, I do not recommend this product.
