How to Prevent Planer Snipe: Causes and 7 Proven Fixes

Planer snipe, the shallow dip cut into a board’s first or last few inches, happens when one end loses support while the cutter head is still engaged, not because the blades are dull or the machine is broken. Left alone, it can waste an entire board meant for a glue-up or a finished top. This guide covers what causes snipe, how to support and feed a board correctly, and which passes and jigs remove it for good.

What Causes Planer Snipe?

Planer snipe is a shallow, tapered dip cut into the first and/or last few inches of a board as it passes through a thickness planer. It happens because a benchtop planer only has one infeed roller and one outfeed roller pressing the board flat against the bed – when the leading or trailing end of the board isn’t yet under both rollers, nothing is holding that end down evenly, so the cutter head bites slightly deeper. It’s a setup and technique issue, not a sign of a broken machine, and it responds well to a few specific fixes.

Three things make snipe worse: infeed/outfeed tables that sit lower than the planer bed (the board tips down as it transitions), dull or unevenly set knives that increase cutting pressure, and taking too much material off in a single pass. The fixes below address each of these, starting with the single most effective one – keeping both ends of the board supported the entire time it’s feeding.

Set Up Your Planer Correctly First

Start with the machine itself before blaming your technique. Set the planer on a flat, stable surface and check the base with a level – a planer that rocks even slightly will telegraph that movement into every board.

Next, check that the infeed and outfeed tables (or extension wings, on a benchtop model) are exactly level with the planer bed itself. Lay a straightedge across the transition from table to bed – any gap or step means the board will dip as it crosses that seam, which is one of the most common causes of snipe on portable planers. Most benchtop models, including popular ones like the DeWalt DW733, have adjustment screws under the tables for exactly this fix.

Feeding Techniques That Actually Eliminate Snipe

Machine setup removes most of the problem; how you feed the board removes the rest. These four techniques address the moment snipe actually happens – when a board’s end is only partially supported.

Support Both Ends With Roller Stands or Sacrificial Boards

The single most effective fix is keeping both ends of the board supported at bed height the entire time it’s feeding. Two options work well: a pair of roller stands set to the exact height of the planer bed at the infeed and outfeed sides (the box above shows the matched pair we recommend), or a “sacrificial board” – an offcut of the same thickness butted directly against your workpiece so the rollers never lose contact with a supported surface. Either way, the board stays flat instead of tipping the moment it clears the table.

Feed the Board at a Slight Angle

Instead of feeding a board straight into the planer, angle it 15 to 30 degrees relative to the cutter head. The board’s leading edge engages the infeed roller gradually instead of all at once, which spreads the pressure change over a longer distance and noticeably softens or eliminates snipe. It costs nothing and takes no setup, so it’s worth trying before you build or buy anything.

Lift the Board Slightly Going In and Coming Out

As the trailing end of the board approaches the infeed roller, lift it slightly from underneath. This presses the leading edge down against the bed instead of letting it tip up, which is what causes the deeper cut. Do the same at the outfeed side as the board’s leading end clears the last roller: keep the exiting end supported and level instead of letting it drop.

Take Shallower Passes

The more material a pass removes, the more the rollers have to compress the board to hold it, and the more that pressure changes as the ends enter and exit – which is exactly what produces snipe. Reducing depth of cut per pass and running the board through twice removes most of the snipe a heavier single pass would leave behind.

Staying well under your planer’s maximum rated depth of cut – even a light 1/16″ pass on figured or wider stock – puts less stress on the rollers and directly reduces snipe severity, on top of whatever technique you’re using to support the board.

Prep Your Wood Before It Reaches the Planer

Some snipe and tear-out problems start before the board ever touches the planer. Use good-quality stock without loose knots or cracks near the edges – a knot at the very end of a board is more likely to chip or tear during the pass. Cut boards to final length first and make sure the ends are square; a rough or angled end feeds unevenly into the rollers.

Check every board for warp and twist before running it through. Sight down the length from one end, and set it on a flat surface to see if it rocks. A cupped, bowed, or twisted board will contact the bed unevenly, which changes the cutting pressure at unpredictable points – not just at the ends. Set aside badly warped boards for a jointer pass first, or replace them; a planer alone can’t fix twist.

Snipe-Prevention Techniques Compared

Technique	Setup Effort	Cost	Best For
Roller stands (matched pair)	One-time, ~10 min	$35–$70	Long boards, repeated milling
Sacrificial board	None, per-board	Free (scrap)	One-off boards, no stands on hand
Feed at 15–30° angle	None	Free	A fast fix with zero setup
Shallower passes	None, slower milling	Free	Figured or wider stock
Homemade snipe jig	30–60 min to build	Free (scrap)	Repeated cuts on the same stock size

Keep the Planer Itself in Good Condition

Sharp, evenly-set knives cut cleanly with less pressure; dull ones tear and require more downforce, which worsens snipe. Check the blades before each project and sharpen or replace them once cuts start looking fuzzy or torn rather than clean. Clean out chips and dust after use, since debris under the rollers or bed can throw off how flat a board sits mid-pass. If you’re also seeing straight lines or ridges rather than a dip at the ends, that’s a different issue – see our guide on why a planer leaves lines in a board for that specific fix.

Jigs, Fixtures, and Other Snipe-Fighting Methods

A homemade snipe jig – a simple scrap-wood cradle that clamps to the infeed and outfeed sides at bed height – does the same job as roller stands for less money if you have scrap and a few clamps on hand. Test it with a piece of scrap first and adjust the height before running a good board through. Commercial fixtures do the same thing with adjustable, reusable hardware if you’d rather not build one.

For rough-sawn stock, hand-planing or trimming the ends square before the board ever reaches the thickness planer helps it feed in flat instead of catching on an angled or splintered edge. If you’re flattening a slab or working from raw-sawn lumber rather than surfaced boards, our guides on flattening slab wood and milling wood from raw logs cover the steps that come before this one. A drum sander can also true up a board’s surface before planing, which removes high spots that would otherwise cause uneven cutting pressure – take light passes, since heavy sanding can gouge the surface.

Troubleshooting: Still Getting Snipe?

If you’re still seeing dips after trying the fixes above, measure how far the snipe extends from each end and note whether it’s happening at the infeed side, the outfeed side, or both – that tells you where the support is failing. Snipe only at the outfeed end usually means the exiting board isn’t being kept level; snipe at both ends usually points back to table alignment.

Re-check that the infeed and outfeed tables are level with the bed, confirm the blades are sharp and set evenly, and test with a scrap board before committing a good one. Small adjustments to table height often solve snipe that persists even with good feeding technique.

Frequently Asked Questions

What Causes Snipe On A Planer?

Snipe happens when one end of a board loses support as it enters or exits the planer, letting the infeed or outfeed roller press that end down deeper than the rest of the pass. Misaligned infeed/outfeed tables and dull blades make it worse.

How Can I Reduce Snipe On My Planer?

Support the wood at both ends with roller stands or a sacrificial board, level your infeed and outfeed tables with the bed, feed at a slight angle, and take shallower passes rather than removing a lot of material at once.

Does Feeding A Board At An Angle Actually Work?

Yes. Feeding a board into the planer at roughly a 15 to 30 degree angle instead of straight-on spreads out the moment the leading edge engages the cutter head, which softens or eliminates the pressure spike that causes snipe. It costs nothing and needs no extra setup.

Is Snipe Preventable On All Planers?

While snipe is common on portable and benchtop planers, it can be minimized to almost nothing with proper table alignment, board support, and feed technique – even if it’s rarely eliminated completely on every single board.

Does Planer Maintenance Affect Snipe?

Yes. Dull or unevenly set blades require more downforce to cut cleanly, which increases pressure changes at the board’s ends. Regular sharpening, cleaning, and blade alignment keep snipe to a minimum along with proper support.

Conclusion

Planer snipe almost always comes down to one thing: a board’s end losing support while the cutter head is still engaged. Level your infeed and outfeed tables, support both ends of the board with roller stands or a sacrificial piece, feed at a slight angle, and take shallower passes. Combine two or three of these and snipe stops being something you fight on every board.
