When shopping for a putter, golfers often encounter two terms:
CNC Milled Putter and Cast Putter.
Many premium brands highlight CNC milling as a key selling point, while cast putters remain one of the most widely used options across the golf industry.
So what’s the real difference?
Is a CNC milled putter always better? Or is a cast putter the smarter choice for some golfers and brands?
Let’s break it down.
The Short Answer
Neither process is universally better.
CNC milled putters excel in precision, consistency, and premium craftsmanship.
Cast putters excel in design flexibility, production efficiency, and value.
The best choice depends on your performance goals, target market, and budget.
What Is a CNC Milled Putter?
A CNC milled putter is machined from a solid block of metal using Computer Numerical Control (CNC) equipment.
Instead of being formed in a mold, material is gradually removed until the final shape is achieved.
This process allows manufacturers to create highly precise dimensions and tight manufacturing tolerances.
Common materials include:
- Carbon steel
- Stainless steel
- Aluminum
- Copper alloys
The result is a putter head that closely matches the original design specifications.
What Is a Cast Putter?
A cast putter is produced by pouring molten metal into a mold.
Once the metal cools and solidifies, the head is removed and finished through machining, polishing, and assembly processes.
Casting has been widely used in golf club manufacturing for decades because it allows manufacturers to create complex shapes efficiently.
Common materials include:
- Stainless steel
- Investment cast steel
- Multi-material constructions
Many of the world’s most successful putter models are cast designs.
Manufacturing Process Comparison
CNC Milled Putters
Process:
Solid Metal Block → CNC Machining → Polishing → Finishing
Characteristics:
- Material removed through machining
- Higher machining time
- Greater dimensional accuracy
- More labor-intensive production
Cast Putters
Process:
Molten Metal → Mold Casting → Finishing → Machining → Assembly
Characteristics:
- Shape created through molding
- Faster production
- Lower manufacturing costs
- High-volume efficiency
The difference starts at the very beginning of production.
Precision and Tolerance
This is where CNC milling has a clear advantage.
Because every surface is machined directly from a digital program, manufacturers can maintain tighter tolerances on:
- Head weight
- Face geometry
- Alignment features
- Critical dimensions
For premium brands focused on consistency, CNC milling offers greater control.
Casting can still achieve excellent quality, but dimensional variation is generally higher compared to precision machining.

Feel and Sound
This is one of the most debated topics in golf.
Many golfers describe CNC milled putters as:
- Softer
- More solid
- More responsive
However, feel is influenced by many factors:
- Material
- Face milling pattern
- Head design
- Insert technology
- Ball type
The manufacturing process alone does not determine feel.
A well-designed cast putter can feel exceptional, while a poorly designed milled putter may not.
Winner: Depends on Design
Design Flexibility
Casting offers significant advantages when creating complex geometries.
Manufacturers can easily produce:
- Deep cavities
- Complex weight structures
- Multi-material designs
- Intricate shapes
Some designs that are economical to cast would be extremely expensive to mill.
For brands developing highly engineered putters, casting often provides greater design freedom.
Winner: Cast
Product Consistency
Consistency is critical for both golfers and brands.
CNC milling offers:
- Repeatable dimensions
- Precise weight control
- Better tolerance management
This becomes especially important for premium product lines where every gram matters.
Winner: CNC Milled
Production Cost
One of the biggest differences between the two methods is cost.
CNC Milled Putters
Require:
- Longer machine time
- More tool wear
- More labor
- Higher production costs
Cast Putters
Benefit from:
- Faster production
- Lower machining requirements
- Greater manufacturing efficiency
For high-volume production, casting is usually the more economical option.
Winner: Cast
Premium Brand Positioning
Many golfers associate CNC milling with premium quality.
Brands often use milled construction to support premium product positioning because:
- Precision is visible
- Face milling creates distinctive aesthetics
- Manufacturing complexity adds perceived value
This perception helps many brands justify higher retail pricing.

Which Putter Is Better for Golf Brands?
The answer depends on the market you’re targeting.
Choose CNC Milling If:
You want:
- Premium product positioning
- High-end craftsmanship
- Tight manufacturing tolerances
- Maximum customization options
- Limited edition or boutique products
Choose Casting If:
You want:
- Competitive pricing
- Faster production
- Larger production volumes
- Complex design structures
- Broader consumer appeal
Many successful brands actually use both approaches across different product lines.
Common Misconception: Milled Always Means Better
One of the biggest myths in golf manufacturing is:
“Milled putters are automatically better.”
The reality is more nuanced.
A putter’s performance depends on:
- Design quality
- Weight distribution
- Face technology
- Material selection
- Manufacturing execution
Milling is a manufacturing method—not a guarantee of performance.
A well-designed cast putter can outperform a poorly designed milled putter.
What matters most is how effectively the design serves the golfer.
Final Thoughts
CNC milled putters and cast putters each have unique advantages.
CNC milled putters offer superior precision, consistency, and premium appeal.
Cast putters offer greater design flexibility, production efficiency, and value.
Neither approach is inherently right or wrong.
The best choice depends on the golfer’s preferences and the brand’s objectives.
For manufacturers and golf brands alike, the goal isn’t simply choosing a process.
It’s choosing the process that delivers the right balance of performance, quality, and value for the intended market.
Because in putter manufacturing, the process matters—but the final result matters even more.
