In-Store Exclusive

This one's worth the trip to the store.

Brands like Weber, Milwaukee, Yeti, and DeWalt restrict where their products can be sold online — and for good reason. In-store buyers get authentic products, full manufacturer warranty, and access to pricing that simply isn't allowed to be advertised on the web.

  • Authorized dealer network · Full manufacturer warranty & support
  • Guaranteed authentic · No counterfeits, no gray-market resellers
  • The brands set these standards · Be wary of sellers who don't follow them

Every order helps keep your local hardware store on the corner.

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

Engineered by DeWalt for precision and lasting performance, the DEWALT 3/8 in. High Speed Steel Countersink Bit delivers clean, consistent countersinks that make screw heads sit flush with your material. Designed for durability and ease of use, this bit is a smart choice for woodworking, cabinetry, and DIY projects where a professional finish matters.

Key features

  • Countersink size: 3/8 in. for a broad, clean countersink that accommodates common screw heads with confidence.
  • Countersink angle: 82 degrees, providing a precise conical recess that seats screws flush with the surface.
  • Material: High Speed Steel (HSS) for durability, heat resistance, and long edge life during drilling and countersinking.
  • Shank: 1/4 in. round shank compatible with standard drill chucks for quick setup and reliable grip.
  • Packaging: Carded single-piece packaging—easy to inspect and store before use.

Why this countersink bit stands out

What sets this DEWALT countersink apart is the combination of robust HSS construction and a precisely engineered 82° angle tailored for consistent flush seating. The 3/8 in. diameter creates a wide, clean entry that reduces tear-out and leaves a smooth surface, while the 1/4 in. round shank fits neatly into most drill chucks without wobble. Built for reliability, this bit maintains sharpness through repeated use, making it ideal for repetitive cabinetry tasks, furniture assembly, and general woodwork where a professional finish is non-negotiable.

Ideal use cases

  • Cabinetmaking and built-in carpentry where precise sink-in of wood screws is essential.
  • Furniture construction and repair, ensuring fasteners sit flush for a polished look.
  • DIY projects that require clean, uniform counterbores in softwood or hardwood.
  • General woodworking where a dependable countersink bit with a standard shank is preferred.

How to get the best results

  1. Mark the screw locations and pre-drill a pilot hole to guide the bit and prevent splitting.
  2. Attach the DEWALT 3/8 in. countersink bit in a drill with a standard 1/4 in. round shank chuck.
  3. Align the bit with the screw hole and drill until the conical recess reaches the desired depth for a flush screw head.
  4. Insert the screw and drive gently to seating without forcing the bit, ensuring a clean, professional finish.

With the DEWALT 3/8 in. High Speed Steel Countersink Bit, you get a purpose-built solution that delivers dependable performance, clean countersinks, and a finish you can trust on everything from cabinet doors to custom shelves. Ideal for woodworkers who value accuracy, durability, and a tool that respects the grain and integrity of the material.

Their Counter
Try local first · we'll wait

The stores we send you to are local and independently run — often for generations, the kind of place where someone behind the counter knows the regulars. We don't own them. We just think they deserve the foot traffic. They can put most of what we sell on their next truck. Ask there before you check out here.

About our directory. National Hardware Group is an independent retailer and directory. The local stores we list and link to are separately owned and operated — we have no ownership stake in any of them, and most pay us nothing to be included. That includes plenty of stores flying a co-op banner that people don't realize are locally owned and run, not operated by a corporation. Store owners can choose to upgrade their listing for an enhanced presence or pickup features, but the base directory is free, and inclusion is never a paid endorsement.
