Why the Four-Facet Split Point Makes a Difference
The 118-degree four-facet split point is like the GPS for your drill bit—it helps the drill find the exact spot and start cutting cleanly without wandering or slipping. Think of it as having sharper guidance when drilling, which saves time and prevents damaging expensive workpieces. This feature reduces the force needed to penetrate metal, meaning your drill works smarter, not harder, and lasts longer between replacements.
Installation and Maintenance Guide
Setting It Up
- Ensure the drill chuck size matches the 2.90 mm shank diameter for a firm hold.
- Secure the drill bit tightly to prevent slippage during operation.
- Use a proper drill press or CNC setup to maintain accurate feed and speed.
- Choose correct RPM settings for the metal type to extend bit life.
- Make sure coolant or lubrication is applied where needed to reduce heat buildup.
Keeping It Going
- Regularly check the drill bit for signs of wear or chipping.
- Clean the bit flutes after each use to prevent clogging and overheating.
- Store bits in a protective case to avoid damage.
- Use proper cutting fluids for tougher metals to maintain sharpness.
- Avoid excessive feed pressure to prevent premature breakage.
