SHUATI 5Pcs Counterbore Set M3-M8 4-Flute HSS-AL Straight Shank Tool

Description

Product Overview

The SHUATI 5‑piece Counterbore Set is engineered for precision machining across a broad spectrum of industrial applications. Each end mill in the set is crafted from high‑speed steel alloy (HSS‑AL) that combines superior hardness with exceptional toughness, allowing the tool to maintain sharp cutting edges even under demanding conditions. The straight shank design ensures optimal rigidity and stability when mounted on a milling machine, reducing vibration and delivering consistent bore quality. The set includes five sizes—M3, M4, M5, M6, and M8—covering the most common counterbore diameters used in metalworking, electronics, and prototype fabrication. With a 4‑flute geometry, each cutter provides a balanced chip evacuation rate and a smooth surface finish, minimizing the need for secondary operations. The compact packaging dimensions (4.02 x 3.07 x 1.3 inches) and lightweight construction (3.88 ounces) make storage and handling effortless, while the robust construction guarantees a long service life.

Usage

This counterbore set is ideally suited for machining environments where speed, accuracy, and tool longevity are paramount. Whether you are producing printed circuit board (PCB) prototypes, fabricating molds for injection molding, or performing routine maintenance on aerospace components, the SHUATI set delivers reliable performance. The HSS‑AL material excels in cutting non‑ferrous metals such as copper and aluminum, as well as ferrous alloys like steel and cast iron, making it a versatile choice for mixed‑material workshops. The straight shank configuration aligns perfectly with standard CNC milling machines, allowing for quick tool changes and seamless integration into automated production lines. By consolidating five essential sizes into a single kit, operators can reduce the frequency of tool swaps, thereby decreasing machine downtime and increasing overall throughput. The set also supports manual milling stations, providing hobbyists and small‑scale fabricators with professional‑grade tooling without the need for extensive inventory.

FAQ

What materials can these counterbore end mills cut?

The SHUATI set is designed for high‑speed cutting of copper, aluminum, steel, cast iron, and other common engineering alloys. Its HSS‑AL composition provides the hardness needed for ferrous metals while maintaining the softness required for non‑ferrous materials.

How do I select the correct size for my application?

Each cutter is labeled with its nominal diameter (M3, M4, M5, M6, M8). Match the cutter size to the required bore diameter of your workpiece. For precise fits, consult the size chart provided by the manufacturer and consider the tolerance specifications of your machining process.

Can these tools be used on CNC machines?

Yes. The straight shank design is fully compatible with standard CNC milling spindles. The cutters can be mounted directly into tool holders or collets, allowing for rapid tool changes and integration into automated machining cycles.

What maintenance is required to keep the cutters performing optimally?

Regularly inspect the cutting edges for wear or chipping, and clean the flutes after each use to prevent chip buildup. Sharpening can be performed by a qualified technician using appropriate grinding wheels for HSS‑AL tools.

Is there a warranty or guarantee for this product?

SHUATI offers a limited warranty covering manufacturing defects. If a cutter fails due to a defect within the warranty period, contact our support team for a replacement or repair solution.
