Tapping bit and coupon

All our inspectors are experienced pipemen, who get that job after a two week training course in which they spend days practicing tapping. They are strictly trained to keep sharp tapping bits, and they know what a coupon done by a dull bit looks like. So they make the contractors save every one, they inspect every one, and then they take the coupons away so they aren't re-used.
