Questions about this item

Does the 118° point angle generate excess heat when drilling metal all day?

The 118° point is designed for general-purpose drilling in wood, metal and plastic; using cutting fluid and proper speed reduces heat build-up during extended use.

Will the 31/64 inch diameter shank fit my 3/8 inch drill chuck?

The reduced shank measures 3/8 inch so it fits any standard 3/8 inch drill chuck without an adapter.

Can I use this bit in an older 3/8 inch corded drill with a keyed chuck?

Yes, the 3/8 inch reduced shank seats securely in both keyed and keyless chucks found on older drills.
