CME 39 Pcs HSS Interchangeable Pilot Counterbore Set Wooden Box

Description

Product Overview

The CME 39‑piece HSS Interchangeable Pilot Counterbore Set arrives in a robust wooden box that not only protects the tools during shipping but also provides a convenient storage solution for workshop environments. Each counterbore is crafted from high‑speed steel (HSS) that has been heat‑treated for superior hardness, ensuring long‑term durability even under heavy machining loads. The set includes a range of interchangeable pilot sizes, allowing users to create precise ½‑inch pilot holes before the counterbore operation, which reduces material stress and improves hole quality.

Designed for versatility, the set is compatible with standard drill chucks and can be used on a variety of materials, including steel, aluminum, stainless steel, and hardwoods. The wooden case features a custom foam insert that holds each bit securely, preventing movement and damage while making it easy to locate the required size quickly. Technical specifications such as a 12‑pound total weight and a model number 500S‑A000 reflect the set’s solid construction and professional‑grade performance, making it a reliable choice for both high‑volume production and precision one‑off projects.

Usage

In a typical machining scenario, the user selects the appropriate pilot bit from the set, inserts it into the interchangeable holder, and drills a pilot hole to guide the subsequent counterbore. This two‑step process is especially valuable when working with hard alloys or composite materials where accurate alignment is critical. The HSS material resists wear and maintains sharp cutting edges, reducing the need for frequent re‑sharpening and extending tool life. Whether you are preparing a mounting surface for a bolt, creating a recessed socket for a fastener, or finishing a decorative inlay, the set delivers consistent results with minimal vibration.

The set is also well‑suited for maintenance technicians who need to service equipment on‑site. The compact wooden case can be easily carried in a tool bag, and the interchangeable design means a single set can replace multiple dedicated pilot and counterbore tools, saving space and simplifying inventory. For hobbyists, the set provides a professional‑grade capability that elevates DIY projects, from custom furniture to automotive modifications, without requiring a large investment in separate tooling.

FAQ

What material are the counterbore bits made from?

The bits are forged from high‑speed steel (HSS) that has been heat‑treated to achieve a hardness level suitable for cutting a wide range of metals and hardwoods. This material choice provides excellent edge retention and reduces the frequency of re‑sharpening.

Can the set be used with a standard drill press?

Yes, the bits are designed to fit standard 1/2‑inch drill chucks, making them compatible with most bench‑mounted and floor‑standing drill presses. The interchangeable pilot holder also fits these chucks, allowing seamless transition between pilot drilling and counterboring.

Is there a warranty or after‑sales service for this product?

CME offers a limited warranty that covers manufacturing defects for a period of one year from the date of purchase. In addition, CME’s technical support team is available to assist with installation, usage tips, and any troubleshooting you may encounter.
