Why the Split Point Design Improves Drilling Accuracy
The 118-degree four-facet split point is like having a guide that centers the drill bit right as it touches the material. Imagine trying to screw in a nail without a guide – it tends to wobble. This design reduces that wobble (‘walking’) by focusing cutting forces at precise points, so your holes start exactly where you want them. It’s essential for clean, accurate holes, especially when working with tough metals where precision matters.
Installation and Maintenance Guide
Setting It Up
- Ensure the drill chuck is clean and debris-free before installation.
- Securely tighten the drill bit in the chuck to prevent slippage.
- Select the correct cutting speed for the metal type.
