When it comes to drilling, two factors often determine the success or failure of your operation: chip control and hole quality. At Fullerton, we believe these aren't just details - they're the foundation of high-performance drilling.
Let's break down what makes a difference in your day-to-day drilling results, and why the design of your drill matters more than you might expect.
What Is Chip Control - And Why Should You Care?
Chip control refers to how well a drill breaks and evacuates chips during cutting. Sounds simple, but poor chip management can spiral into a host of problems - slower cycle times, tool failure, even safety risks.
Here's why effective chip control should be non-negotiable:
- Higher Productivity: Clean chip evacuation allows you to run faster speeds and feeds without clogging.
- Better Heat Management: Short, broken chips remove heat from the cutting zone more efficiently, preserving tool life and reducing workpiece damage.
- Smooth Evacuation: Controlled chips are easily flushed out by coolant or carried away via flute design - no jamming, no drama.
- Reduced Tool Breakage: Poorly formed chips can wedge in the flutes, leading to overheating, galling, or catastrophic failure.
- Safer Operations: Long, stringy chips (aka "birds nests") are not only annoying - they're dangerous for operators.

Why Hole Quality Isn't Just About Looks
Hole quality goes far beyond making a part "look good." It's about precision, reliability, and reducing waste. Factors like diameter accuracy, concentricity, straightness, and surface finish directly affect how your part performs - and whether it passes inspection.
Here's what great hole quality delivers:
- Functional Integrity: A precision hole ensures proper fit and performance, especially in assemblies and mating parts.
- Less Rework and Scrap: Better holes mean fewer rejected parts and more consistent production.
- Confidence and Credibility: Clean, precise holes reflect well on your process - and help build trust with customers.
- Critical Reliability: In high-stakes industries like aerospace or medical, poor hole quality isn't just a defect - its a risk.

The Fullerton Approach
Behind every Fullerton drill is careful engineering - geometry, flute design, edge prep, coatings - all optimized to deliver efficient chip control and exceptional hole quality.
