Balax - M12x1.75 Metric Coarse D12 Thread Limit Bottoming Thread Forming Tap - Cobalt, Bright Finish, 3-3/8" OAL, Series BXMOTL

Bottoming chamfers are used for threading blind holes to the bottom. They have 1 to 2 threads.

Bright provides a smooth, polished finish on the tool. It increases chip flow in softer materials such as aluminum, wood and plastic.

Cobalt is harder than high speed steel and provides better wear resistance. It is commonly used on high tensile alloys.
