M48x1.5 fine pitch hand taps
Hand Tap M48X1.5 DIN 2181/2 6H HSS is designed for making M48 metric internal threads with a pitch of one and a half millimeters in structural steels up to eight hundred mega pascals; two-member operation without load jumps promotes the maintenance of a six H class fit.
Performance characteristics: nominal diameter forty-eight millimeters; pitch one and a half millimeters; outline sixty degrees according to ISO 68-1; bore tolerance field 6H according to ISO 965; right-hand design; straight chip grooves for uniform evacuation. Ground high-speed steel stabilizes the edge and reduces micro chipping. According to DIN 2181/2, the layout includes an inserting member (I) and a finishing member (II), which equalizes torsional loads and promotes alignment; in the practice of sequential work, the order of transitions is facilitated by the M48x1.5 Hand Tapping Set. Recommended drill bit for the thread: forty-six and a half millimeters; lubrication with emulsion or active oil improves the finish of the bottom of the coil.
- Calm profile shaping - the I/II split extinguishes torque fluctuations and reduces the risk of chafing along the entire length of the outline.
- Longer edge life - precision HSS grinding keeps micro roughness low and slows abrasion during handwork.
- Accuracy in the 6H field - controlled effective diameter promotes a positive "pass/fail" test result.
- Station organization - with clear member markings unifies selection and speeds up rotation between stages.
Reference to DIN 2181/2, ISO 68-1 and ISO 965 guarantees compatibility with inspection instruments, and the use of the M48x1.5 Hand Tapping Set reinforces the repeatability of results and stability of coil geometry.
