Accusize H.S.S. Solid Cap Screw Counterbore Set, 3 Flute Straight

Description

Product Overview

The Accusize H.S.S. Solid Cap Screw Counterbore Set is a precision-engineered tool designed for industrial and scientific applications requiring flush or countersunk recesses for cap screws. Constructed from high-speed steel (H.S.S.) with a straight shank design, this 7-piece set includes sizes: 6#, 8#, 10#, 1/4”, 5/16”, 3/8”, and 1/2”. Each tool is crafted for durability and consistent performance under heavy-duty use. The 3-flute geometry ensures efficient chip removal, reducing heat buildup and extending tool life. Ideal for mechanical assembly, fabrication shops, and maintenance teams needing reliable counterboring solutions.

Usage

This set is engineered for use in industrial workshops, manufacturing plants, and scientific labs where cap screws are used to secure components with flush or countersunk heads. Common applications include mounting panels, assembling machinery, and creating clean aesthetic finishes on metal surfaces. The straight shank design ensures compatibility with standard drill presses and power tools, while the H.S.S. material withstands high temperatures without deformation. Suitable for both professional machinists and DIY enthusiasts working with steel, aluminum, or other non-ferrous metals.
