Case Study: Real Business, Real Results
At a machining shop in Detroit needing to improve drilling precision on steel components, they upgraded to our Carbide Jobber Drills.
"Switching to these drills significantly cut down on reworks due to holes being off-diameter. The four-facet split point keeps everything straight and true."
Marcus Jennings – Production Manager
Boosted drilling accuracy by over 25%, slashed scrap rates by 15%
Why the Four Facet Split Point Makes the Drilling Recipe Better
The four-facet split point on these drills is key to achieving spot-on holes without the drill wandering. Imagine trying to start a hole in super slick ice without slipping—this split point acts like cleats, biting into the surface to hold the drill steady right from the get-go. This means you waste less time adjusting your position and get cleaner, more precise results every time you drill.
Installation and Maintenance Guide
Setting It Up
- Ensure the drill chuck fits the 6.40mm shank diameter securely.
- Check the drill is tightened firmly in the chuck to avoid slippage.
- Use appropriate coolant or cutting fluid for metal drilling to extend tool life.
- Set drilling speed according to material specifications, generally lower RPMs for harder metals.
- Test on scrap material to adjust feed rate and depth before starting your main project.
Keeping It Going
- Clean chip flutes regularly to prevent clogging and overheating.
- Inspect drill tip for wear or dullness; resharpen or replace as needed.
- Store drills in a dry, safe spot to avoid corrosion.
- Avoid excessive force to prevent snapping or premature damage.
- Keep coolant flow consistent during use to keep temps down and prolong drill life.
Frequently Asked Questions
Q: Can I use these carbide jobber drills on stainless steel?
Yes, these drills are designed to handle stainless steel as well as other common metals with ease.
Q: What does the 118-degree four-facet split point do?
This point design reduces drill wandering and helps the drill start cleanly for accurate holes.
Q: Are standard cut and double cut drills interchangeable?
They serve similar purposes, but double cut is better for harder materials or faster drilling rates.
Q: What size drill chuck fits this tool?
A chuck that accepts a 6.40 mm shank is needed for proper fit and operation.
Q: How deep can I drill with the 50mm flute length?
You can drill holes approximately up to the flute length; deeper holes may risk poor chip evacuation.
Q: What tolerance accuracy does this drill maintain?
It holds a precise tolerance of +.000/-.0005 inches for consistent hole sizing.
Q: Is coolant necessary when using these drills?
While not always mandatory, using coolant extends tool life and improves performance.
Q: Can I resharpen these carbide drills?
Yes, but it requires specialized equipment to maintain the split point geometry properly.
-
Q: How do I know when it’s time to Replace or Resharpen the burr?
Replace or Resharpen it when you notice decreased cutting efficiency or visible wear on the cutting edges.
