High-speed steel countersinks provide good wear resistance in a wide range of countersinking applications. Single-flute countersinks are suitable for use at high speeds. They leave clean edges on holes and have a high, positive rake that reduces vibration as they expand the top of an existing hole in a workpiece to ensure screws install flush with the surface of the workpiece.

High-speed steel countersinks provide good wear resistance in a wide range of countersinking applications. Six-flute countersinks provide fast material removal and leave a smooth finish as they expand the top of an existing hole in a workpiece to ensure screws install flush with the surface of the workpiece. They remove more material with each revolution and typically provide more wear resistance than countersinks with fewer flutes.

High-speed steel countersinks provide good wear resistance in a wide range of countersinking applications. General purpose 3-flute countersinks are the most commonly used type of countersink. They expand the top of an existing hole in a range of materials to ensure screws install flush with the surface of the workpiece. Three-flute countersinks typically provide better chip clearance and perform better when machining stringy materials than countersinks with more flutes.

Cobalt steel zero-flute countersinks provide good wear resistance when machining hard materials at high speeds. Zero-flute countersinks have a single flute that passes through the center of the countersink. This minimizes vibration and chatter during use and prevents chips from sticking to the tool. Zero-flute countersinks leave smooth, clean edges on holes and are used to expand the top of an existing hole in a workpiece to ensure screws install flush with the surface of the workpiece. They are commonly used for installing aluminum frame storefronts, glass and window design, and architectural metalworking applications.

Solid carbide countersinks provide excellent wear resistance when machining the toughest materials, such as cast iron and stainless steel. Six-flute countersinks provide fast material removal and leave a smooth finish as they expand the top of an existing hole in a workpiece to ensure screws install flush with the surface of the workpiece. They remove more material with each revolution and typically provide more wear resistance than countersinks with fewer flutes.

Cobalt steel countersinks are harder than high-speed steel countersinks and provide good wear resistance when machining hard materials at high speeds.

Cobalt steel countersinks are harder than high-speed steel countersinks and provide good wear resistance when machining hard materials at high speeds. General purpose 3-flute countersinks are the standard choice for expanding the top of an existing hole in a variety of materials to ensure screws install flush with the surface of the workpiece. Three-flute countersinks often provide better chip clearance and perform better when machining stringy materials than countersinks with more flutes.

Cobalt steel countersinks are harder than high-speed steel countersinks and provide good wear resistance when machining hard materials at high speeds. Single-flute countersinks are suitable for high-speed countersinking operations. They leave clean edges on holes and have a high, positive rake that reduces vibration as they expand the top of an existing hole in a workpiece to ensure screws install flush with the surface of the workpiece.

High-speed steel countersinks offer good wear resistance in a wide range of countersinking applications. General purpose 4-flute countersinks expand the top of an existing hole in a workpiece to ensure screws install flush with the surface of the workpiece. Four-flute countersinks typically provide more wear resistance than countersinks with fewer flutes.

High-speed steel countersinks provide good wear resistance in a wide range of countersinking applications. Also known as machine countersinks, 4-flute countersinks have a long shaft that allows them to be used in lathes, screw machines, and CNC machines. They expand the top of an existing hole in a workpiece to ensure screws install flush with the surface of the workpiece. 4-flute countersinks typically provide more wear resistance than countersinks with fewer flutes.

These countersinks have a threaded shank that keeps them securely attached to a compatible handheld electric or pneumatic power tool during use. This helps ensure the countersink will not fall off the tool when it's being used in hard-to-reach areas. Countersinks are used to expand the top of an existing hole in a workpiece to ensure screws install flush with the surface of the workpiece. These countersinks can also be used to debur holes.
