PUTTER INSERTS: OPTIONS & DEVELOPMENTS

At spryevo.com, our development of the putter insert is never ending, diligent, and most of all fun.  Only what is tested and proven is released to the public for only a select few brands, which we find interesting and efficient to work with.  Our solutions are not a copy of how the putter was in stock condition, but instead we aim for consistency, response, and feedback. 

When replacing a putter insert, ask yourself 3 questions:

1.  Do I want to add weight or keep it the same?

2.  Do I want a metal face or non-metal?

3.  Do I want a smooth face or a grooved face (milled or horizontal)?

 

For now, we prefer to concentrate on five proven materials:


1.  TWILL CARBON FIBER LAMINATE:  

This material was developed from our experience in motorsport.  We are not the first to introduce a carbon fiber hitting surface on a putter, but we aim for it to be the most advanced.  The material is imported from Italy and is of the same grade used by teams in Formula 1 racing.  The manufacturing side is then performed in the motorsport hub of Charlotte, North Carolina, USA.  Inserts from this material provide the following advantages:

1.  No added weight because of it's low density

2.  Polymer feel because of its resin content

3.  Pronounced response and sound because of the fibers and their reinforcing properties

4.  Smooth glossy surface with a stealthy aesthetic often seen on exotic sports cars



2.  MILLED TELLURIUM COPPER (TeCu)

Copper has long been a favorite metal as a putting surface because it is a soft metal with a high density, often perceived by the golfer as greater feel.  We choose to work with a tellurium copper because of it's machinability and mechanical properties.  Another advantage is the ability to achieve different aesthetics ranging from a high luster polish, to machined grooves.  A most recent notable win with a copper insert putter is Brooks Koepka, 2017 US Open.  Te-Cu inserts provide the following advantages:

1.  Adding weight to the putter face because of its high density, anywhere from 30-60 grams, depending on geometry.

2.  The quality feel and deep sound of a high density metal against the ball during impact

3.  Milled to a precise thickness with textured cut grooves (smooth is also available)

3.  Amber aesthetic which can take on many looks:  smooth polished shine, brushed satin, blasted satin (rose gold), or a rough light cross-milled machining.



3.  MILLED AIRCRAFT ALUMINUM

Not just any aluminum will do, aircraft grade provides a higher quality for added durability, function, and aesthetic.  This is the lightest metal solution possible, besides magnesium, for a putter head insert, and it only adds about 10g in weight.  This grade of aluminum has great machining characteristics, which can provide an accurately grooved face, or a flat, smooth brushed surface.  Advantages of this insert include:

 

1.  A precisely milled metal insert solution, which only adds 10-20 grams to the club head.

2.  Versatile face finish properties from precision grooves to a smooth brushed surface, with no corrosion maintenance.

3.  The silver aesthetic provides a unique sound at ball impact, compared to plastic. 



4.  ALUMIDE

As technology advances, so do the inserts at www.spryevo.com  After extensive research and testing, we are pleased to offer alumide 3D printed inserts from www.shapeways.com.  It's a hybrid material made from aluminum powder and a polyamide.  The result is a light, durable, responsive solution that sends the ball rolling smoothly.  We are working on populating our entire collection with this material, and you can find an examples here like:  #9XG

White Hot XG Marxman

 Works 2-ball

 TaylorMade

 

Characteristics include: 

1.  A precise hybrid insert, which does not add any weight to the club head.

2.  A smooth face is shown, but many face groove patterns can be printed, like horizontal grooves, diamonds, and more, with no corrosion maintenance.

3.  The silver aesthetic provides a unique sound and pronounced response at ball impact compared to stock plastic. 



5.  HP Multi Jet Fusion Black

3D printing with the HP Multi Jet Fusion and www.shapeways.com has been very exciting.  High accuracy, incredible detail, speed, and cost effectiveness make this a great aftermarket solution to the needs of the putter.  The nylon hybrid material is tough, light, black in color, and its combination with the horizontal grooves make for a great roll off the putter face.  Not everyone can buy this material from Shapeways yet, but we are stocking some insert designs in this material.
