Value Collection JY4995304 Straight Flute Tap M30x3.50

Product Description

The VALUE COLLECTION JY4995304 is a straight flute tap designed for cutting M30x3.50 metric coarse internal threads in through-holes and shallow blind holes. Made from high-speed steel with a bright, uncoated finish, it delivers reliable performance across a range of ferrous and non-ferrous materials. The plug chamfer style provides 3 to 5 chamfered threads at the lead, making it suited for through-hole applications where the tap can pass fully through the workpiece. With an overall length of 5.4375 inches and a thread length of 2.5625 inches, this tap is built for use in manual tapping setups as well as machine tapping operations.

This tap is used in machining, fabrication, and maintenance applications where large-diameter metric coarse threads are required. Typical installation scenarios include tapping threaded holes in structural components, heavy equipment parts, dies, fixtures, and machine bases. It is commonly used by machinists, tool and die makers, and maintenance technicians working with M30 thread specifications in industrial or shop environments.

Key Features

• M30x3.50 metric coarse thread size for large-diameter internal thread cutting
• Plug chamfer with 3 to 5 lead threads for through-hole tapping
• High-speed steel construction for durability across common workpiece materials
• Bright, uncoated finish suitable for use with cutting fluid
• 4 straight flutes for efficient chip evacuation in through-hole applications
• Right-hand thread direction, D5 thread limit for standard fit tolerance

Compatibility

Designed as a standard M30x3.50 metric coarse plug tap compatible with manual tap handles, tapping heads, and machine tapping setups sized for large-diameter taps.

Installation Notes

This tap is typically used by machinists and tooling specialists in shop or production environments. Secure the workpiece fully before tapping and ensure the pilot hole diameter is correctly sized for M30x3.50 metric coarse threads per standard tap drill charts. Apply appropriate cutting fluid throughout the tapping operation to reduce heat and extend tool life. Reverse the tap periodically to break chips when tapping deeper holes.
