In my experience Tap and Die Company are a reputable company, selling good material.
Don't think that they are a back street, "knock 'em out cheap" company. FAR from it.
They supply industry, with well known and respected brands, such as Totem.
If their products are good enough for Rolls Royce, they are good enough for me!
I have always been satisfied with the Taps, Dies and boxes bought from them. (I have BSW, BSF, UNF and ME40 boxes on the shelf ) and Perkins Heritage Group have bought from them.
Look at their website to see if they have what you want.
Did you ring the correct number, 020 – 8888 -1865? If amything, I have had problems ending the conversations!
According to the website, they open again at 0900 on Thursday 24th August.
