How the Four Facet Split Point Makes Drilling Easier
A four facet split point on a drill bit is kind of like having a perfectly sharpened pair of scissors that cut right from the start instead of getting stuck or slipping. This design reduces the chatter and walking that sometimes happens when you start drilling, meaning your holes go exactly where you want them. This makes precise drilling a breeze and reduces wear on the tool, so your bit lasts longer and your work comes out cleaner every time.
Installation and Maintenance Guide
Setting It Up
- Ensure your drill chuck matches the 3.73 mm shank diameter for a secure fit.
- Clean the chuck thoroughly before inserting the drill to avoid slippage.
- Set your drill press or handheld drill to appropriate speed for carbide tools—typically slower than high-speed steel bits.
- Use cutting fluid or lubricant to reduce heat buildup and extend bit life.
- Double-check the alignment before starting to drill to prevent wobbling.
Keeping It Going
- Always clean the bit after use, removing any metal shavings or debris.
- Store drills in a protective case to avoid damage or dullness.
- Inspect regularly for signs of wear or chipping before use.
- Sharpen carbide drills professionally when dull instead of discarding.
- Use proper feed pressure—too much force can break the bit, too little causes overheating.
