The EAGLE CUTTING TOOL MT-330-350-P-I is an M33.0x3.50 high-speed steel (HSS) metric plug tap designed for cutting internal threads in metal workpieces. The plug chamfer style — typically 3 to 5 threads of lead — makes it suitable for both through-hole and blind-hole threading applications. At a thread size of M33.0 with a 3.50 mm pitch, this tap is built for larger-diameter metric threading work common in heavy fabrication, machinery repair, and industrial maintenance environments. Installation is performed by licensed machinists, tool-and-die professionals, and experienced trade mechanics.
This metric plug tap is used in applications requiring standard ISO metric threads at the M33.0x3.50 specification. It is suited for ferrous and non-ferrous metals in shop, field, and maintenance environments. The import designation indicates a cost-effective sourcing option for production shops and service operations where volume threading of large-diameter metric fastener holes is routine.
Designed as a standard M33.0x3.50 metric plug tap compatible with conventional tap wrenches, adjustable tap handles, and machine tapping setups accepting the appropriate shank size for this thread class.
Tapping operations should be performed by qualified machinists or trade mechanics familiar with proper cutting speeds, lubrication, and chip-clearing technique for large-diameter taps. Use an appropriate cutting fluid to reduce heat and extend tool life. Secure the workpiece firmly before beginning and back the tap out periodically to clear chips and prevent binding or breakage. Always verify the correct drill size for the M33.0x3.50 thread specification before starting the pilot hole.
