AccusizeTools Thread Self Reversing Tapping ITH5 4066 Review

Wrong thread and will not thread into die head. I returned and the replacement was the same. I contacted Accusize and they took my email and said they would check it and get back to me with a solution, two weeks and no contact. I thought a company in Canada would have better service. A chopping head is useless if I can't use it in a mill.
