Besly Special Purpose Taps for Cast Iron

These Besly Special Purpose Piloted Taps help locate the workpiece for tapping especially when holes enter at an angle. The pilot acts as a locator and guide, eliminates special fixtures and reduces tap breakage. Pilot diameters will fit holes drilled for 75% thread height.
