Why the Four-Facet Split Point Design Makes a Big Difference
The 118-degree four-facet split point isn’t just technical jargon—it’s what helps these drills bite into the material without slipping or wandering off target. Imagine trying to drill a perfectly round hole freehand: without a steady guide, the drill tip can scoot around, ruining the hole. The four-facet split point acts like an autopilot, centering the drill right where you want it and getting a clean start every time. This means fewer mistakes and less rework, saving you time and effort on the job.
Installation and Maintenance Guide
Setting It Up
- Match the drill diameter (0.0760 in) precisely to your workpiece requirements
- Ensure the drill chuck is clean and free of debris before insertion
- Tighten the chuck firmly but avoid over-tightening to prevent drill damage
- Use appropriate coolant or lubricant to extend tool life during drilling
- Set drilling speed to match material hardness for optimum results
Keeping It Going
- Clean chips off the drill flute regularly to avoid clogging
- Inspect the split point tip for dullness or damage before each use
- Store drills in a dry, safe place to protect carbide edges
- Use a sharpening service when edges become noticeably worn
- Avoid drilling without proper lubrication to prevent overheating
