Frequently Asked Questions
Q: What is the benefit of indexable over solid HSS? A: Indexable tools maintain a constant length and never need re-sharpening; you simply replace the low-cost carbide edge.
Q: Will this work in a standard 1/2" chuck? A: Yes, the shank is sized to fit standard industrial drill chucks and tool holders.
