Cleveland C54232 Hand Tap 6-40 Taper Rh Hss 3-flute

Product Description

The CLEVELAND C54232 is a 6-40 taper chamfer, right-hand, straight-flute hand tap designed for cutting internal threads in both blind and through-hole applications. Made from high speed steel with a bright uncoated finish, it holds up well across a broad range of workpiece materials. The tap carries an H2 thread limit and is ground to a 2B/3B class of fit, making it a reliable choice for UNF threaded fastener assemblies where standard tolerance is required. Overall length is 2 inches with a thread length of 0.38 inches. Machinists, toolroom technicians, and maintenance mechanics are the typical end users.

This tap is suited for production and maintenance tapping in alloy steel, carbon steel, aluminum, and free-machining stainless steel. The taper chamfer — typically 8 to 10 threads of lead — makes it well-suited for starting threads cleanly, particularly in through-hole work. It also performs in blind holes when adequate chip clearance is maintained. The straight-flute geometry keeps the design simple and compatible with standard tap wrenches and tapping heads used in manual operations. It belongs to Cleveland Series 1001.

Key Features

• 6-40 UNF thread form, right-hand cut, 2B/3B class of fit
• Taper chamfer for easy thread starting in through-hole and blind-hole applications
• High speed steel construction for durability across ferrous and non-ferrous workpieces
• H2 thread limit for standard tolerance thread production
• Bright uncoated finish suitable for use with cutting oils and standard tapping fluids
• 3-flute straight-flute design compatible with manual tap wrenches and machine tapping setups

Compatibility

Designed for use in alloy steel, aluminum, carbon steel, and free-machining stainless steel workpieces requiring 6-40 UNF internal threads in blind-hole or through-hole configurations.

Installation Notes

This tap is installed by machinists or maintenance technicians using a standard tap wrench or tapping fixture. Always secure the workpiece and ensure the tap is started square to the hole to prevent thread misalignment or tap breakage. Apply an appropriate cutting oil or tapping fluid before and during use. Back the tap off periodically to break chips, especially in blind holes, and never force the tap against the bottom of a blind bore.
