Constant Pressure Tamper 58.35mm — 30lb Precision | MHW-3Bomber

The MHW-3Bomber Flash Constant Pressure Tamper 2.0 (58.35mm, Walnut / Black Titanium) is a spring-loaded espresso tamper engineered for home baristas and café professionals who demand perfectly consistent 30lb tamping pressure with every single shot.

Key Features

• Guaranteed 30lb Constant Pressure: Internal triple-spring mechanism automatically calibrates and releases at exactly 30lb of force, eliminating over- or under-tamping every time.
• Rippled / Threaded Base Design: The precision-machined rippled base promotes even puck distribution and reduces channelling for a cleaner, more uniform espresso extraction.
• Premium Walnut Handle: Ergonomically shaped walnut wood handle provides a warm, natural grip and reduces wrist fatigue during high-volume tamping sessions.
• Black Titanium-Plated Finish: The titanium-coated stainless steel base resists corrosion, staining, and daily wear while delivering a sleek, professional aesthetic.
• 58.35mm Diameter Precision Fit: Sized specifically for standard 58mm portafilters found on the majority of home and commercial espresso machines, ensuring full edge-to-edge puck coverage.
• Durable SUS304 Stainless Steel Core: Food-safe, rust-resistant stainless steel construction built to withstand years of daily use in demanding café environments.
• Repeatable Extraction, Shot After Shot: Removes the human variable from tamping, making it ideal for training new baristas or dialling in a consistent recipe at home.

Frequently Asked Questions

What espresso machines is the 58.35mm tamper compatible with?

The 58.35mm diameter is compatible with the vast majority of 58mm portafilters, including popular brands like Breville, De'Longhi, ECM, Rocket Espresso, and La Marzocco. Always verify your portafilter's inner basket diameter before purchasing.

How does a constant pressure tamper work?

The Flash Tamper's internal triple-spring mechanism compresses as you press down and automatically clicks or releases once exactly 30lb of pressure is reached, preventing you from applying too much or too little force regardless of technique.

Is the walnut handle durable enough for daily café use?

Yes. The walnut handle is sealed and shaped for repeated daily use. It is recommended to keep it away from prolonged water submersion, but standard wiping and cleaning will not affect its integrity or appearance over time.

What is the difference between the threaded base and a flat base tamper?

The threaded (rippled) base creates micro-channels in the puck surface that can aid even water distribution during extraction and reduce channelling. A flat base produces a smooth, uniform puck surface. Both are effective — choice often comes down to personal preference and grind consistency.
