Powerful and economical
- Self-centring split point for precise spot drilling and noticeably less effort required.
- High resistance to breakage due to the roll-forged manufacturing process for robust assembly and workshop applications.
- Fast drilling progress due to geometry specially developed for Würth.
- Vaporised surface for good adhesion of coolants and lubricants, as well as reduced buildup of material deposits.
- High production quality for consistently good drilling results.
- Long service life for economical use.
The service life can be significantly increased by using sufficient coolant and lubricant.
