Detail 01
.690 in (17.52 mm) cup diameter
Large side of medium. The rim's high point sits near the center, so it plays smaller than the number suggests.

SchilkeStandard Series Cornet Mouthpiece - Group II, 18 Silver
1/8
Independent shopping perspective
The Korena take
Silver-plated Schilke cornet mouthpiece, .690-inch cup with a 26 throat. Larger Group II diameter for players who want a rich, brilliant tone with room to breathe.
Strong match
Who this is for
- Brass band cornet players wanting a full, projecting sound
- Players stepping up from a .677 rim without a large jump
- Anyone whose current rim feels cramped on long phrases
Consider the trade-offs
When to look elsewhere
- Developing players still building strength for a large diameter
- Upper-register commercial work that wants a shallower cup
- Trumpet players — cornet mouthpieces use a different shank
What matters in use
The specifications, translated
Catalog numbers tell only part of the story. These are the details most likely to change how this product feels, sounds, or fits into a setup.
Detail 02
Standard number 3 rim contour
Rounder profile rather than a flat cushion. More flexibility and quicker response, but less shelf to lean on.
Detail 03
26 throat
Standard bore across most of Group II, so resistance stays familiar if you try a neighboring size.
Detail 04
Rich, brilliant tone
Bright edge over a full core — carries through an ensemble rather than sitting underneath it.
Detail 05
Group II sizing
Schilke's larger range, .674 to .720 inch. The 18 sits mid-pack, leaving room to move either direction.
Detail 06
Silver plating
Standard finish. Wipe dry after playing; tarnish is surface-level and comes off with polish, not scrubbing.
Final check
Know before you order
- 01Mouthpiece only — no pouch, brush, or case included
- 02Cornet shank; it will not seat properly in a trumpet
- 03Give a .690 rim two to three weeks before judging endurance
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01What size is the Schilke 18 cornet mouthpiece?
.690 inch (17.52 mm) cup diameter with a 26 throat, in Schilke's larger Group II range.
02Is the 18 too big for me?
It measures .690 inch, but the high point sits near the center so it feels smaller than it is. Coming from the .677 model 16, the step up is small.
03How does the 18 compare to the 18B4?
The 18B4 keeps the same diameter but uses a medium-shallow cup and semi-flat number 4 rim — more resistance and comfort up top. The 18 is the standard all-around version.
04Can I use this on a trumpet?
No. Cornet mouthpieces use a different shank than trumpet. Schilke lists its trumpet models separately.
