Cleveland C56062 Hand Tap 1/4-20 Unc Ticn Hss

Product Description

The CLEVELAND C56062 is a 1/4-20 UNC straight-flute hand tap designed for cutting internal threads in metalworking applications. Part of the Series 1002TICN line, it features a plug chamfer and a titanium carbonitride (TiCN) coating over a high speed steel (HSS) body. The TiCN coating increases surface hardness and reduces friction, extending tool life compared to uncoated taps. With 4 flutes and a right-hand thread direction, this tap is built for controlled hand tapping operations in both blind holes and through holes. Overall length is 2.5 inches with a thread length of 0.63 inches. Licensed tradespeople and skilled machinists are the typical users.

This tap is suited for threading 1/4-20 UNC holes in ferrous and hard materials. It is rated for use in cast iron, stainless steel, and steel. The plug chamfer style — with a moderate lead-in — makes it appropriate for starting threads in through holes or for continuation tapping after a taper tap in blind hole work. It handles both blind hole and through-hole threading applications. The H3 thread limit provides a standard oversize tolerance, accommodating coatings and typical class 2B fit requirements in production and maintenance environments.

Key Features

• High speed steel construction provides toughness for hand tapping operations
• Plug chamfer with 4 flutes suits both blind hole and through-hole threading
• H3 thread limit for class 2B fit compliance
• Right-hand, 1/4-20 UNC thread form for standard unified coarse thread applications
• Rated for cast iron, stainless steel, and steel material applications

Compatibility

Designed for 1/4-20 UNC blind hole and through-hole threading in cast iron, stainless steel, and steel. Part of the CLEVELAND Series 1002TICN hand tap line.

Installation Notes

This tap is installed by machinists, toolmakers, or maintenance technicians using a standard tap wrench or T-handle. Always secure the workpiece and ensure the tap is started square to the drilled hole to prevent breakage. Apply appropriate cutting fluid for the material being tapped, particularly when working with stainless steel. For blind holes, clear chips frequently to prevent tap binding and breakage.
