CBN Boring Tools - Brazed, Bar(s), Tipped, and Inserts

A question I get asked quite often, is what sort of tool would be best for hard boring my x,y or z. Well that all depends on the answers I get for these questions:

What is the min. bore diameter?

What is the bore depth?

Are you willing to use a different tool?

Instead of sending me answers to these questions, here is a quick guide for boring applications:

Size of Bore = Recommended Tool

8mm or smaller= CBN Tipped Brazed Boring Tools

8mm – 10 mm= CCMW 06 or CCMW 2(1.5) CBN Insert

10mm – 16 mm= CCMW 09 or CCMW 3(2.5) CBN Insert

25mm – up= CNMA CBN Insert
