Why we built NHG
You might find it for less locally. Independent retailers often offer competitive pricing — some products are even cheaper in-store than online.
Real expert advice — not search results. Independent hardware staff know their inventory and the local conditions you're working in.
Keep the neighborhood working. Every dollar spent at an independent retailer returns roughly 3x more to your local economy than at a national chain.

About Product Overview

This IRWIN countersink bit is a replacement part sized for #10 screws, cutting a clean, tapered pilot hole and countersink in one pass through wood. The high speed steel construction holds an edge through repeated use, and the 1/4" hex shank drops straight into any standard drill or impact driver.

Use it to replace a worn or damaged bit in a countersink set without buying the whole kit over again. Packaged as a single bit, it's a straightforward swap-in fix for anyone doing regular woodworking or trim carpentry.
