Cracked Cymbal: What to Do Before You Replace It
A crack does not spread because the cymbal is broken — it spreads because the crack tip concentrates stress every time the cymbal flexes. Stop that concentration with a small drilled hole or a clean cut, and a cracked cymbal can stay in service for years. Jump straight to buying a replacement and you spend $200 on a problem that a 3mm drill bit would have paused.
The short answer
If the crack is at the edge of the cymbal and under about 3 to 5mm long, smooth the edges, drill a small hole just past the crack tip, and re-mount the cymbal with a plastic sleeve so it can move freely. That buys months or years of playable life. If the crack runs across the playing surface or reaches the bell, the cymbal is structurally finished and a cut-down or a replacement is the realistic answer. Never clamp a cymbal tight on its stand — that is usually what caused the crack.
None of this restores the original sound, and none of it is a repair in the sense of "as new". It is damage control that extends usable life, which is usually what you actually want.
Crack or keyhole: two different problems
Players use "cracked" for two failures that behave completely differently, and mixing them up leads to the wrong fix.
A crack is a linear split in the bronze, almost always starting at the edge or at the bell hole. It has two ends, a tip and an origin, and it grows from the tip as the cymbal flexes.
A keyhole is an elongation of the centre hole, caused by the cymbal rubbing against a bare stand post or by tightening the wing nut. It is not a split — it is wear, and it does not propagate the way a crack does. A keyholed cymbal is often perfectly playable for years, and the fix is a sleeve or a grommet rather than any cutting.
The practical difference: a keyhole you live with, and a crack you treat. A crack is active and growing; a keyhole is a fixed shape that stays where it is unless the mounting gets worse.
Why cymbals crack, and how to stop the next one
Bronze is strong but it fatigues, and cymbals fail for a small number of very predictable reasons.
- Hitting the edge straight-on rather than at an angle. A glancing blow lets the cymbal flex; a direct hit drives energy into the rim and starts a crack.
- Over-tightening the wing nut. A cymbal should be able to rock freely on its stand. Clamped tight, it cannot flex, so every hit concentrates at one point.
- A bare metal post through the centre hole. This is what causes keyholing, and it can turn into a crack at the hole over time.
- Bad storage. A cymbal leaning on its edge against a wall for months develops a stress point exactly where it touches.
- Age and metal fatigue. A cymbal that has taken 300 hours of hard playing will eventually fail somewhere, no matter how well you treat it.
The first three are habits, and changing them is free. A cymbal that never gets clamped and never gets hit square at the edge will usually outlive the drummer's enthusiasm for it.
::: callout
The counterintuitive part: a crack spreads not because the cymbal is weak but because the tip of the crack is a stress concentrator — the flexing energy piles up at that one point and rips the metal a fraction further on every hit. That is why drilling a small hole just beyond the tip works: it turns a sharp point into a smooth radius, spreading the same energy over a larger area and stopping the tear.

Where the crack is matters more than how big
Location decides the outcome far more than length.
Edge cracks under 5mm are the best case. They are common, they grow slowly, and they respond well to being smoothed and stopped. Many end up as a slightly shorter cymbal with a tone difference you stop noticing within a week.
Edge cracks over 10mm are still sometimes salvageable by cutting, but you are removing a visible chunk and the sound changes more. Cutting a 20-inch crash down to a 17 or 18-inch is a real option that turns a cracked crash into a smaller, darker crash.
Cracks running inward across the bow are the worst case. They cross the area that vibrates most, they grow fast, and any fix is cosmetic. This is where repair money is better saved for the replacement.
Cracks at or through the bell are effectively terminal. The bell is the stiffest, most stressed part of the cymbal, and a crack there will travel around the hole and kill the cymbal within a short time.
Cutting and drilling: what actually works
Two techniques buy time, and both are about removing the stress concentration.
Drilling. Mark a point 2 to 3mm beyond the visible end of the crack tip, along the direction the crack is travelling, and drill a hole about 3mm in diameter with a sharp bit at low speed. The hole radiuses the tip and stops the tear. Do it with the cymbal supported flat on a block of wood, and use a little cutting oil. You can do this at home; a repair shop will do it cleaner.
Cutting. For a deeper edge crack, a technician can cut a smooth concave scallop that removes the entire crack and leaves no sharp internal corner. This is best done with a metal-cutting tool by someone experienced, and it will noticeably change the cymbal's sound and weight. A poorly cut scallop with a sharp corner is no better than the crack it replaced.
What does not work: gluing, taping, welding and epoxy. All of them either fail to hold under vibration or add mass that changes the sound badly. If someone offers to weld a cymbal, the answer is no.
The stack and effects route
If a crack is beyond sensible repair, the cymbal is often still valuable as a different thing. A cracked crash does not have to go in the bin — it can be repurposed.
Stacking. Two cracked cymbals stacked loosely, or a cracked crash over a splash, produce a dry, trashy sound that is genuinely useful in modern music. Stacks are forgiving because the sound is meant to be chaotic; the crack that ruins an open crash is barely noticeable in a stack.
Effects and percussion. A small cracked cymbal can be mounted on a stand as a bell, a trash crash or a hi-hat auxiliary, or used in a hand-held setup. If you compose or record, a broken cymbal is a free texture.
Many pros deliberately buy cheap cracked cymbals on the used market for exactly this. A cymbal that is worth $30 to a collector because of a crack is worth $30 to a producer who wants that exact sound.
When a crack is genuinely terminal
Be honest about the point at which you stop throwing time at a cymbal.
It is terminal when the crack grows visibly between sessions, when it has reached the bell, when the cymbal has lost its open wash and rings as a dull thud, or when two separate cracks have started and are heading toward each other. Any of those means the bronze is fatigued through its thickness, and a hole at the tip will just move the problem 5mm along.
There is also a value argument. A cymbal you love and have played for 15 years is sometimes worth cutting down to keep it alive. A $150 budget crash with a growing bow crack is not; the drill hole, the time and the compromised sound add up to more than the drum shop's price for a fresh one.
Preventing the next crack: setup, angle and technique
The next cymbal will fail the same way unless you change the setup that killed this one.
Set cymbals at 15 to 30 degrees of tilt toward you, so the stick edge makes a glancing contact rather than a flat one. Fit a plastic or nylon sleeve over the stand post, and add a felt above and below the cymbal. Tighten the wing nut finger-tight only — the cymbal should wobble if you nudge it, and a cymbal that does not move is being asked to absorb energy it cannot take.
Review your technique when you play loud. Crashes are meant to be hit with a sweeping, angled motion that lets the cymbal swing; hitting down into a fixed edge is the single most common cause of edge cracks. Working on cymbal choke technique and general stroke control teaches the glancing motion that saves edges, and if you are shopping for a replacement, the best cymbals for beginners guide points at models that are cheap enough to replace without pain.
One bonus: knowing where the crack is means you can read it in a chart when a part calls for a sustained crash and you are improvising around a dying cymbal. The symbols for crashes, chokes and accent patterns are set out in our explainer on how cymbals are notated, which is worth ten minutes before your next rehearsal.
::: verdict
Before you spend a cent, put the cymbal under a bright light and look at the crack: if it is at the edge and under 5mm, mark a point 2 to 3mm past the tip, support the cymbal flat on wood, and drill a 3mm hole at low speed with a drop of cutting oil. Then remount it with a plastic sleeve and tighten the wing nut finger-tight so it can wobble. That single afternoon of work is the cheapest way to keep a favourite cymbal in the rotation.

Warranty, resale and the honest cost maths
Run the numbers before committing to either path.
Warranty. Most major cymbal makers offer a limited warranty — often 2 to 3 years — against manufacturing defects, but cracks from playing are not covered. It is worth a look if the crack appeared early, at the hole, or in a pattern that suggests a flaw, because a successful claim is a free replacement.
Resale. A cracked cymbal sells for roughly 25 to 40% of the same model uncracked, depending on the size of the crack and the brand. A cut-down cymbal is worth its new size, not its original value, so a 20-inch cut to 17 inches is priced as a 17.
The maths. A repair that costs $40 of a technician's time plus a lost edge on a $180 cymbal is only worth it if you love that specific cymbal. If it is a generic model you replaced on a whim last time, buying the same model again is faster and sounds better. Be honest about which one you are holding.
Frequently asked questions
The questions readers send us most about what to do with a cracked cymbal.
It can be stabilised, not restored. A small edge crack under 5mm can be stopped by drilling a 3mm hole just past the tip, and deeper edge cracks can be cut down by a technician to remove the damaged area. Both keep the cymbal playable but change its weight and sound. Welding, gluing and epoxy do not work and usually make things worse.
Remove the stress concentration at the crack tip. Mark a point 2 to 3mm past the visible end of the crack in the direction it is travelling, support the cymbal flat on a block of wood, and drill a 3mm hole at low speed with a little cutting oil. The radiused hole spreads the flexing energy that was previously piling up at a sharp point.
Yes, if the crack is at the edge and short. It is a low-cost way to buy months of playable life and it takes a few minutes. Drill just past the tip rather than through the crack itself, use a sharp bit and low speed, and keep the cymbal flat and supported so the bit does not skate. If you are not confident, a drum shop will do it cheaply.
A crack is a split that grows from a tip as the cymbal flexes, and it needs treating. A keyhole is wear — the centre hole stretched oval by rubbing on a bare stand post or by an over-tightened wing nut. A keyhole does not propagate, and most keyholed cymbals stay playable for years if you fit a plastic sleeve and stop clamping the nut down.
Replace it when the crack runs across the playing surface or reaches the bell, when it grows visibly between sessions, when two cracks are travelling toward each other, or when a cheap model would cost less to replace than to repair. Cracks at the bell in particular are terminal, because the bell is the most stressed part of the cymbal and the crack will travel right around the hole.
