Case Study: Real Business, Real Results
Seattle, Washington - Precision Tool Co. upgraded their drill bits to CARBIDE JOBBER DRILLS to ensure tighter tolerances and faster cycle times.
"Switching to these drills gave us cleaner holes and greatly reduced the amount of rework needed on our aluminum parts."
Linda Fowler – Production Manager
Increased drilling accuracy by 35% and reduced downtime by 20%
Why the 118-Degree Four-Facet Split Point Makes a Difference
The split point design means the tip of the drill starts cutting right away, reducing the chance that the drill will skid or wander on the material’s surface. Think of it like the difference between trying to start a pencil point on rough paper versus a fine-tipped mechanical pencil: the split point gets you exactly where you want with no fuss. This is especially handy when precision counts or working with delicate materials.
Installation and Maintenance Guide
Setting It Up
- Ensure the drill chuck is clean and free from debris before inserting the drill.
- Secure the drill bit firmly in the chuck, avoiding overtightening to prevent damage.
- Set the correct drilling speed based on the material being worked on.
