Value Collection JY4995908 M11x0.75 Hand Tap 4-flute Hss

Product Description

The VALUE COLLECTION JY4995908 is a straight-flute hand tap designed for cutting M11x0.75 metric fine internal threads in through-holes and blind holes. Manufactured from high speed steel (HSS) with a bright, uncoated finish, this tap operates with a right-hand thread direction and carries a 6H class of fit with a D4 thread limit. The plug chamfer — typically 3 to 5 threads — makes it suitable for starting threads in through-holes or continuing threads in partially tapped blind holes. With an overall length of 2-15/16 inches and a thread length of 1-1/4 inches, it fits standard tap wrenches used in machine shop and field maintenance applications.

This tap is suited for threading metric fine M11x0.75 holes in a variety of materials where high speed steel tooling is appropriate, including mild steel, aluminum, brass, and plastics. The 4-flute straight-flute geometry provides balanced cutting and chip control in these materials. It is sized for hand-tapping operations rather than machine tapping, making it a practical choice for maintenance technicians, machinists, and trade professionals performing field repairs or low-volume threading tasks where a lathe or CNC machine is not available.

Key Features

• M11x0.75 metric fine thread profile for precise, fine-pitch threading
• Plug chamfer (3-5 thread lead) works in through-holes and continuation of blind holes
• High speed steel construction provides durability across a range of common workpiece materials
• Bright uncoated finish allows direct inspection of cutting edges before use
• 4-flute straight-flute design delivers balanced cutting forces and chip clearance
• 6H class of fit and D4 thread limit ensure consistent, gauged-fit results

Compatibility

Designed for use with standard tap wrenches and T-handle tap holders that accept the shank diameter of an M11 metric hand tap. Suitable for metric fine threading applications requiring an M11x0.75 6H thread form.

Installation Notes

Hand tapping should be performed with appropriate cutting fluid to extend tap life and improve thread quality. Secure the workpiece firmly before starting; misalignment during entry is a primary cause of tap breakage. Advance the tap forward approximately one full turn, then back off one-quarter turn to break chips before continuing. If the tap becomes difficult to turn, back it out to clear chips before proceeding.
