Document revision: 2026-10-27.1. This is a documentation revision, not a new hardware version. Physical sample testing has not been performed for this release. Test dates, sample serial numbers, operators and independent approval are not available. Values copied from product specifications are declared specifications, not measured results.

Versioned specification snapshot

Snapshot taken on 27 October 2026 from the linked product pages and their technical tables. This revision does not identify a manufacturing batch. Before ordering, confirm the current shipping revision, exact burr set, electrical requirements and carrier with support. Dimensions below preserve the source order; an unconfirmed width/depth/height orientation is not added.

The YEH-98L dimension correction in this revision is 220 × 150 × 330 mm. It supersedes the earlier 230 mm figure in site copy. A signed physical measurement and hardware serial number are still pending. Rated electrical figures are product declarations, not a measured power-consumption or grinding-throughput result. The current grinder specifications state 220 V, 50/60 Hz; confirm the current unit before use. A plug adapter does not convert supply voltage. For a 110/120 V installation, confirm an appropriately rated step-up transformer and the unit's requirements with support.

Listed burr-option matrix

This matrix transcribes the English purchase options visible on the product pages on the snapshot date. “Listed” means a purchase configuration offered by YARRAMATE; it does not claim an independent installation test or compatibility with every burr of the same diameter. No precise bolt pattern, thickness or adapter part number has been supplied for verification.

Fit conditions to confirm

• Match the exact burr maker, series, generation, diameter, thickness, inner opening, rotation, mounting pattern and carrier clearance. Ask for the corresponding carrier or adapter identifier; do not buy by diameter alone.
• The 98L uses a 98 mm flat-burr platform. Supported 102 mm sets require the corresponding dedicated 102 mm carrier adapter. This page does not say the adapter is included free or that all 102 mm sets fit.
• 80L and 120L are flat-burr platforms; 83C is conical. Flat and conical sets are not interchangeable merely because a nominal diameter looks similar.
• Blind means there are no screw holes on the cutting face. It does not mean conical, entirely hole-free or necessarily magnetic. Different rear/side/magnetic mounting arrangements exist.

Terminology source: LeBrew, Blind Burrs | The Pinnacle of Grinding Design, published 12 June 2025, section “What Are Blind Burrs?” and “Mounting Methods”. This source explains terminology; it is not a fit certificate for YEH grinders.

Choosing a configuration

Start with espresso/filter use, your coffee and roast preferences, available counter space, mains supply and a confirmed burr/carrier combination. The 80L is an 80 mm flat-burr option; 98L offers the documented 98/102 mm path; 120L targets professional single-dose use; 83C offers a conical platform for buyers considering body-led espresso profiles. These are selection conditions, not measured taste rankings. Burr size alone does not establish cup quality, speed or value.

Check current price and selected burr on the linked product page. Grinder delivery can take up to two months depending on burr supply and assembly; ask for an estimate for your exact configuration. Consult the grinder after-sales policy for coverage and Wholesale Orders for business quotations.

Revision and approval record

2026-10-27.1: first public source snapshot, 98L dimension correction preserved, native flat/conical platforms distinguished and 102 mm adapter condition made explicit. Hardware revision, physical fit verification date, test operator and reviewer: not supplied. No sample installation passes are claimed.
