Spiral Flute Tap: MJ4 x 0.70, MJ, 3 Flute, Modified Bottoming, 4H Class of Fit, HSS-E-PM, Bright/Uncoated MPN:10001070

The spiral flute tap is designed to drill into hard materials such as stainless steel or carbon steel effortlessly. Its MJ4 x 0.70 size makes it suitable for creating holes up to a depth of approximately four times its tap diameter in these harder substrates, offering high efficiency and longer life compared to standard taps when faced with similar taskloads. The modified bottoming feature further enhances its ability to thread start in difficult-to-machine metals, while the HSS-E-PM material allows heat dissipation reducing buildup during drilling for consistent results over extended periods of use. Such characteristics make this spiral flute tap an essential tool among machine shops, maintenance departments or those operating CNC machines where tapping hard materials is a regular requirement on their job sites.
