Pegasus 207N Electric Grinder Blade Set with Ghost Tooth Burrs

If your grinder produces inconsistent grounds—some powdery, some boulders—it’s likely the burr set. Many home baristas hit a wall improving extraction, not because of beans or machines, but because standard flat or conical burrs can’t achieve the fine uniformity needed for high-quality brewing. Upgrading the burr set is often the simplest, most effective way to raise extraction precision without replacing the whole grinder.

The Pegasus 207N electric grinder blade set uses a 500g ghost tooth burr configuration. This specific burr type offers a balanced grind profile suitable for filter and espresso applications, aiming to improve particle uniformity over standard flat burrs.

What Is the Pegasus 207N Electric Burr Set?

The Pegasus 207N is an electric burr replacement set designed for compatible grinders. Its defining feature is the 500g ghost tooth burr set—also called a flat-tooth or curved-tooth burr—offering a different grinding geometry compared to traditional flat or conical burrs. The burr set weighs 500g in total and is built for motorised (electric) operation. The part number for this specific assembly is 207N- (207N-blade disc).

Why Choose a Ghost Tooth Burr Design?

Ghost tooth burrs, also referred to as curved or flat-tooth burrs, differ from conventional flat burrs by having a modified tooth geometry. Instead of straight, uniformly aligned edges, ghost tooth burrs feature a more complex, waved or angled edge design. This design aims to produce a more even particle distribution, which can enhance extraction consistency—especially important for light to medium roast single origins and filter brewing methods. While not as common as flat or conical burrs, ghost tooth designs are valued for balancing fines and boulders better than standard flat profiles.

Key Specifications of the Pegasus 207N Set

• Brand: Pegasus
• Weight: 500g (total burr set weight)
• Part Number: 207N- (207N-blade disc)
• Type: Electric burr set (motorised grinder compatible)
• Burr Type: Ghost tooth (flat-tooth/curved-edge design)

These specifications confirm the set is engineered for precise motorised grinding, with the ghost tooth configuration intended to refine grind uniformity over traditional flat burrs. The 500g weight indicates a solid build suited for regular use in home or light commercial settings.

How Burr Geometry Impacts Coffee Grinding

Burr type plays a crucial role in determining grind size distribution. Traditional flat burrs tend to produce a more uniform particle size but can generate more fines, which affect shot clarity and mouthfeel. Conical burrs, meanwhile, may create a wider distribution range, sometimes leading to uneven extractions. Ghost tooth burrs aim to bridge this gap by offering a middle ground—delivering a grind profile that reduces both extreme fines and boulders, thereby supporting more even water flow through the coffee bed during brewing. This can be particularly beneficial for methods sensitive to extraction balance, such as V60, Kalita Wave, or even espresso when dialled in carefully.

How to Install or Use the 207N Electric Burr Set

To install or upgrade your grinder with the Pegasus 207N electric burr set, follow grinder manufacturer instructions for burr replacement. Ensure the grinder is compatible with 500g burr assemblies and electric drive systems. Key steps typically include:

• Disconnecting power to the grinder
• Removing the existing burr set (following tool and safety guidelines)
• Installing the 207N ghost tooth burr set in the correct orientation
• Reassembling and testing the grinder at a mid-range grind setting

Always check compatibility with your specific grinder model before purchase. Proper installation ensures the burr’s performance benefits are fully realised.

Frequently Asked Questions

What is a ghost tooth burr and how is it different from flat or conical burrs?

A ghost tooth burr features a modified, often curved or wavy cutting edge design, differing from the straight, uniform edges of traditional flat burrs or the cone shape of conical burrs. This geometry is intended to produce a more even particle size distribution, potentially reducing both fines and boulders for improved extraction consistency.

What grinder models are compatible with the Pegasus 207N electric burr set?

The article does not specify compatible grinder models. However, the 207N- set is designed for electric grinders and is built to handle a 500g burr assembly. Check with your grinder manufacturer or retailer to confirm fit before purchasing.

Does the Pegasus 207N burr set improve espresso extraction?

The ghost tooth design aims to create a balanced grind profile, which may improve extraction consistency. While it is not explicitly designed solely for espresso, careful dialling in could support espresso brewing, especially for blends or dark roasts where a broader particle spectrum is more forgiving.

What is the weight of the Pegasus 207N burr set?

The complete Pegasus 207N electric burr set weighs 500g. This includes the full ghost tooth burr assembly, which is built for durability and regular use in electric grinders.

How does the 207N burr set affect grind uniformity?

The ghost tooth burr geometry is engineered to reduce inconsistency in grind size—producing fewer extremely fine or large particles compared to standard flat burrs. This can lead to more uniform extraction, especially noticeable in filter coffee brewing methods.
