What are conical vs flat burr coffee grinder?

Conical vs flat burr coffee grinder are used to create a fine grind of coffee beans that is suitable for making espresso-like drinks. These grinders are also known as espresso machines, but they are not designed to make espresso. Keep Learning Most conical and flat burr coffee grinders are built for home use. They are available individually or as part of a bigger espresso machine.

conical burrs

Cone-shaped burrs are called conical burrs. They are found in both commercial and home grinders and are the primary burrs found in manual grinders. A conical burr set consists of a ring-shaped inner burr that fits comfortably inside the outer burr.


  • The outer burr is usually larger than the inner burr.
  • The conical burrs are not as strong or durable as flat burrs.
  • They are found in commercial and home grinders and are
  • the primary burrs found in manual grinders.
  • A conical burr set consists of a ring-shaped inner burr that fits comfortably inside the outer burr.


  • These burrs tend to be more difficult to maintain than flat burrs.
  • In order to keep a conical burr set in good condition, you must oil it often.
  • The conical burr must be oiled regularly to maintain its shape and avoid excessive wear.
  • You can oil the burr by simply dipping it in vegetable oil or another type of lubricant.
  • Conical burrs are used on some sewing machines.
  • They have the advantage of being able to squeeze into incredibly small areas. They have the disadvantage of being harder to control than flat burrs.

Flat Burrs

Flat burrs have two flat rings. They feature horizontal, angled teeth. Ring spacing determines size. Conical burrs, on the other hand, grind vertically. One burr is nestled inside another.

Conical burrs, on the other hand, grind vertically. Burrs are nested. Conical burrs fit many tools. A flat burr consists of two parallel rings stacked flat.

They feature horizontal, angled teeth. Two parallel rings stacked flat create a flat burr. They feature horizontal, angled teeth.

As a result, improved particle size uniformity is simpler to achieve.” Indeed, he believes flat burrs will always perform better than conical burrs. “The better the granulometry precision, the more exact the parallelism.”

Since the lowest burr must be on the motor shaft, conical burrs cannot achieve complete concentricity and will remain decentered. Conical burrs’ problematic alignment may cause complications.

There are ways to level out a flat burr and conical burr grinder’s discrepancies. First, they heat up quicker in the first 10-15 minutes. When not in use, they cool down similarly. Flat burr grinders need more mechanical force to maintain a steady heat level.

Flat vs Conical Burr Coffee Grinder – Minor Considerations

While comparing flat vs conical burr coffee grinder, you should consider a few smaller aspects. The main differences between the two include the shape of the grinding surface and the design of the grinding head.


On average, conical burr grinders cost less than flat burr grinders. Baratza’s Virtuoso conical burr grinder costs less than half the price of a comparable flat burr grinder. A conical burr’s mechanism is simpler than a flat burr’s, allowing for a reduced price tag.


Conical burr grinders have a lower RPM than flat burr grinders, which require a higher RPM to force all of the beans into the grinding chamber.


As the beans grind against one another, they produce a little bit of heat. If your grinder uses conical burrs, this heat is minimal. Flat burrs cause considerably more friction, which produces more heat.

It’s ideal to avoid heat as much as possible until you’re ready to brew so that your cup may retain all of its delightful flavors and fragrances.

chamber and out the sides.

A disc sander’s faster-spinning blades need a strong engine, but the increased horsepower doesn’t translate to more noise.

What Does It All Mean?

This article gives great advice about the difference between cone burrs and flat burrs. In fact, I’m confident that cone burrs will soon overtake flat burrs in popularity.

Flat burr grinders make a louder noise than conical burr grinders, are hotter, and cost more. Yet, flat burr grinders produce a more consistent grind than conical burr grinders. It’s important to consider grind consistency when purchasing a burr grinder.

Conical burrs ground coffee because they keep a continual flow of hot water and air over the beans. Flat burrs tend to trap more waste than conical burrs, which means they will need a lot of maintenance and can cause the grinder to be less effective.

Conical vs Flat Burr Coffee Grinder: Which is Better?

Flat burr grinders are good for all types of ground coffee and grinding mediums. They’re less expensive than conical grinders.

Conical burr grinders are very reliable and convenient; however, they lack a high-quality blade-grinding mechanism.

Flat, conical, and ball-shaped grinders have diverse uses and materials. They make flour, spices, espresso, and other drinks.
