"Switching to these carbide drills boosted our hole consistency and saved us significant rework time. Their long-lasting sharpness meant less downtime for tool changes."

How a Four-Facet Split Point Gives You Better Drilling Accuracy
The four-facet split point is kind of like having a guide on the drill tip, helping it start smoothly without wandering all over the place. Imagine trying to poke a hole in a soda can with a dull pencil; it tends to slip or scrape before it bites. With this split point design, the drill bites in cleanly right from the start, which means your holes will be right where you want them—every time. This reduces mistakes, keeps your cuts crisp, and saves you time fixing errors later.
Installation and Maintenance Guide
Setting It Up

Keeping It Going
- Regularly inspect drill edges for wear or chips to maintain precision
- Clean debris and metal shavings from flutes after each use to prevent clogging
