Automotive Industry

There are 1.4 billion light-duty vehicles worldwide. This number is projected to double by 2030, and triple by 2050. That’s over 4 billion vehicles around the globe!


This skyrocketing trend increases the demand for all sorts of automotive parts and the grinding solutions for all stages of production. Eagle Superabrasives’ lines of diamond and CBN (cubic boron nitride) grinding wheels are manufacturered with these solutions in mind.

Grinding Wheels for the Automotive Industry

Eagle works closely with automotive manufacturers to help them produce the best quality parts and components without burns, burrs or chatter.

Whether you are grinding, cutting, finishing, shaping or polishing, we’ve got you covered.

Our diamond and CBN wheels are commonly used in the manufacturing of engine components, such as camshafts, crankshafts, valves and cylinder heads.

Superabrasives help operators to achieve the specific, polished surface finishes their parts require to ensure optimal operation, leak-free matting surfaces, and reduced wear and friction.

Welded body and chassis parts also typically require grinding to smooth, sharp edges and precise finished surfaces.

Advantages of Superabrasive Wheels


Diamond and CBN wheels are made for the high-volume production environments typical of the automotive industry, and offer a number of advantages over conventional grinding options, including:

  • Durability
  • Longevity
  • Thermal Stability
  • Fewer Wheel Changes
  • Improved Shape Retention
  • Less Truing Required
  • Ability to Grind Hard-to-Machine Materials
  • Quicker Grind Times per Part

These advantages combine to help increase overall efficiency for a variety of automotive grinding applications.

Compared to conventional abrasives, such as silicon carbide and ceramic alumina, superabrasives display cooler operating temperatures, produce smoother surface finishes, and can machine up to 100 times more components.

What Sets Eagle Apart?

Eagle’s superabrasive wheels are used in a wide range of automotive grinding applications, including but not limited to:

  • Spark Plugs
  • Windshields & Mirrors
  • Brake Pads
  • Crankshafts
  • Camshafts

Our wheels are suited for high-speed and precise grinding while providing good surface quality.

In particular, our metal bond wheels provide excellent results when glass cutting, a critical application for windshield and side window manufacturers.

Our customers benefit from a stable manufacturing process, high-quality product finishes, increased dressing intervals, long tool life, and shorter grinding cycles.

If any of these sound familiar and are something you are interested in improving, give Eagle a call!

Grinding Round Tools

Pro Flute Aero Wheels

Formulated with Eagle Superabrasives’ proprietary hybrid porosity technology, the Pro Flute Aero Bond utilizes pores in the bond to help keep the wheel cool, all while maximizing edge retention and cutting faster.

A combination of Eagle’s aggressive-cutting Aero Max and form-holding Pro Flute bonds, the Pro Flute Aero was developed with the intention of grinding tools with 5/8” or smaller diameters.

Round tool manufacturers looking for the best in production, efficiency, and price per part should try a Pro Flute Aero wheel today.

Grinding Valve Seats

SharpTEC Wheels for Stellite

Stellite is a material unlike any other, and Stellite-tipped tools require a superabrasive wheel specifically designed to grind them.

Unlike typical CBN wheels, which notoriously struggle to grind Stellite, Eagle’s SharpTEC CBN wheels cut through effortlessly, leaving no burrs or burns on your parts.

Additionally, our customers experience a significant increase in their wheel life due to increased cutting efficiency.

What sets our SharpTEC wheels apart?

Unlike the rounded CBN particles used in standard formulations, our SharpTEC bond is made with super-sharp, pointy CBN particles, allowing the wheel to slice through Stellite without excessive glazing.

Complete with our proprietary induced-porosity bond providing superior cooling, Eagle SharpTEC wheels offer an unbeatable combination of extremely fast cutting and non-burning high performance for your Stellite-grinding applications.

Grinding Camshaft/Crankshaft

VitTEC Vit. Bond Wheels 

Eagle’s proprietary VitTEC diamond and CBN wheels are made for operators looking for more out of their vitrified grinding wheels.

What sets our VitTEC wheels apart from other vitrified diamond & CBN wheels is a process called Cold Isostatic Pressing (CIP). While ordinary vitrified wheels are only pressed from two dimensions, ours are evenly pressed from every single side, angle, and radii during the CIP process, guaranteeing without fail that our wheel segments have perfectly consistent density throughout the abrasive section.

As a result, our VitTEC wheels provide several advantages over our competition, including:

• High thermal stability
• Dress while mounted to achieve precise wheel forms that last longer, lengthening the time between re-dressings
• Porous bond helps coolant remove heat from contact point & allow for increased stock removal
• Improved edge quality of tools
• Faster cycle times

Beveling Glass

OptiTEC Wheels

Eagle Superabrasives’ OptiTEC grinding wheel line offers metal and resin bonds specialized to suit your application.

Our OptiTEC wheels eliminate chipping issues by using our superior blend of diamond particles to maintain the sharpest cutting edge in any operation.

A sharper diamond is critical when grinding glass. If the diamond is too blocky or rounds over too quickly due to wear, the wheel will start to chip the glass and ruin your parts.

With our metal bond OptiTEC wheels, you may be able to grind well over 10,000 meters of glass before re-truing the wheel radius.

Cutting or Notching

CutMax Cutoff Wheels

Tired of “commodity” cut-off wheels? Feel like you are not getting enough bang for your buck?

Eagle Superabrasives’ CutMax cut-off wheels add versatility to your grinding operation.

With three specialized bond options, CutMax wheels give you the choice to cut faster or last longer:

• CutMax – Our standard, most versatile cut-off bond; ideal for a wide variety of cutting applications

• CutMax Green – Our fastest cutting, most aggressive cut-off bond; ideal when cutting without coolant and when getting the job done as quickly as possible is the top priority

• CutMax CNC – Specifically formulated to run on CNC machines with flood coolant, this cut-off bond is formulated to extend your wheel life and hold its edge longer than typical cut-off wheels

All CutMax wheels are made with the most friable diamond on the market, allowing for fast cutting action while maintaining cooler temperatures.

Grinding Tubes

ETEC Wheels (Electro Chemical Grinding)

All Eagle Superabrasives’ electrochemical grinding (ECG) wheels feature our propritary E-TEC bond formulation.

E-TEC is designed to provide upgraded performance through higher conductivity, allowing for consistent burr-free cuts.

While cutting 3.5mm stainless tubing, Eagle’s E-TEC wheel achieved 24% longer life than our competition in side-by-side testing.

With E-TEC grinding wheels, you can expect:

• Guaranteed burr-free cutting

• Wheels that are consistently conductive

• Durability, wear resistance, and longer-lasting copper & nickel coatings

• More than twice the abrasive depth of our competitors for maximum wheel life – E-TEC offers a 5/8” standard depth for all ECG cutoff wheels, blowing away the industry standard of 1/4”

What People Are Saying


“Eagle Superabrasives has always come through for us with competitive pricing and great customer service. If they don’t have the exact grinding wheel that we need, they will customize a wheel for our end-user’s needs and create a new part number for it. I wish I had discovered Eagle SA years ago.”
