Essential Safety Equipment

Riving Knife - MOST IMPORTANT

  • Thin metal plate that sits directly behind the blade
  • Prevents wood from closing back on the blade
  • Primary defense against kickback
  • Never remove unless absolutely necessary
  • Rises and falls with blade - stays aligned

Blade Guard

  • Clear plastic cover over spinning blade
  • Prevents accidental contact with blade
  • Contains dust and debris
  • Remove only when it prevents a specific cut
  • Reinstall immediately after that cut

Push Sticks & Push Blocks

  • Push stick: Hook end pushes back of board, keeps hands away
  • Push block: Downward pressure on board, shoe pushes back
  • Use when ripping boards narrower than 6"
  • Hands should NEVER be within 6" of blade
  • Have multiple push sticks ready at all times

Featherboards

  • Angled fingers press work against fence or table
  • Provides consistent pressure through entire cut
  • Helps prevent kickback by keeping work steady
  • Position before the blade, not beside it
Kickback Prevention

What is Kickback?

When wood binds on the blade, it can be violently thrown back at the operator at speeds exceeding 100 mph. This causes the majority of serious table saw injuries.

Causes of Kickback

  • Fence not parallel to blade (pinches wood)
  • Wood closing on back of blade (no riving knife)
  • Releasing wood before cut is complete
  • Using fence for crosscuts (traps cut-off)
  • Internal wood stress causing wood to twist
  • Reaching over spinning blade

Prevention

  • Always use the riving knife
  • Stand to the side of blade, never directly behind
  • Keep fence parallel to blade (check alignment)
  • Never use fence for crosscuts - use miter gauge
  • Never reach over or behind spinning blade
  • Use featherboards to maintain consistent pressure
  • Let blade stop completely before retrieving pieces
  • Check wood for warps and internal stress
Blade Selection
Blade TypeTeethBest For
Rip blade24-30Cutting with grain, fast lumber ripping
Crosscut blade60-80Cutting across grain, clean edges
Combination blade40-50General purpose, most DIY work
Plywood/Melamine80+Sheet goods, veneers, no chipout
Thin kerfVariousLess powerful saws, less waste

Kerf Considerations:

  • Full kerf (1/8"): More stable, best for powerful saws (2+ HP)
  • Thin kerf (3/32"): Less waste, easier on weaker motors
Dado Blades

What is a Dado?

A flat-bottomed groove cut across the grain (dado) or with the grain (groove/rabbet). Used for joinery - shelves, drawer bottoms, cabinet backs.

Stacked Dado Set

  • Two outer blades plus chipper blades in between
  • Combine to create exact width needed
  • Maximum width typically 13/16" (fits 3/4" plywood)
  • Produces flat-bottomed dadoes

Important Notes

  • Remove riving knife and blade guard for dado cuts
  • Never exceed maximum width for your saw
  • Use featherboards to hold work down
  • Make multiple passes for deep dadoes
  • Note: Dado blades illegal in some countries (UK, EU)
Rip Cuts vs Crosscuts

Rip Cuts (With the Grain)

  • Use the fence to guide the cut
  • Keep board flat on table and against fence
  • Use push stick for narrow rips (under 6")
  • Riving knife prevents wood closing on blade
  • Check fence is parallel to blade before cutting

Crosscuts (Across the Grain)

  • Use miter gauge or crosscut sled - NOT the fence
  • Fence causes cut-off to trap between fence and blade
  • This trapped piece causes kickback
  • If fence needed for stop, use auxiliary fence that ends before blade
  • Crosscut sled provides safest, most accurate crosscuts

⚠️ NEVER use fence and miter gauge together for crosscuts

The cut-off piece gets trapped between the fence and blade, causing violent kickback.

Safe Operating Zone

Clearance Requirements

  • Front: Minimum 36" clearance for operator stance
  • Back: Minimum 36" for outfeed support
  • Sides: 24" minimum for maneuvering
  • Infeed: Support for long boards entering saw
  • Outfeed: Table or roller stand for cut pieces

Operator Position

  • Stand to the left of the blade (for right-hand fence)
  • Never stand directly in line with blade
  • Maintain balanced stance
  • Keep body positioned so kickback goes past you
SawStop & Flesh-Sensing Technology

How It Works

  • Blade carries small electrical signal
  • Human contact changes signal (flesh is conductive)
  • Detection triggers brake within 5 milliseconds
  • Brake stops blade before serious injury occurs
  • Typically results in minor nick instead of amputation

Considerations

  • Brake cartridge needs replacement after activation (~$100)
  • May need blade replacement too if damaged
  • Can't use on wet wood or conductive materials
  • SawStop brand pioneered; others entering market
  • Premium cost but potentially life-changing safety

Additional Information

About This Table Saw Guide

The table saw is arguably the most useful - and most dangerous - tool in a workshop. It excels at rip cuts (cutting wood to width) and with proper accessories, handles crosscuts, dadoes, rabbets, and many joinery operations. Its power and precision make it indispensable for furniture making and cabinetry.

However, table saws cause more serious injuries than any other power tool. This guide emphasizes safety above all else. The riving knife is your most important safety feature - it prevents the most common cause of serious injury (kickback from wood closing on the back of the blade). Never remove it unless absolutely necessary.

Understanding when to use the fence versus the miter gauge, proper push stick technique, and correct body position can mean the difference between a close call and a life-altering injury. Take the time to learn proper technique before operating any table saw.

Frequently Asked Questions

Why can't I use the fence for crosscuts?

When crosscutting against the fence, the cut-off piece becomes trapped between the fence and the blade. The spinning blade catches this piece and throws it back at the operator with tremendous force (kickback). This is one of the most common causes of serious table saw injuries. Always use a miter gauge or crosscut sled for crosscuts. If you need consistent length cuts, use a stop block clamped to the fence that ends before the blade - the piece can then move away from the blade after the cut.

What causes table saw kickback?

Kickback occurs when the back (rising) teeth of the blade catch the wood and throw it violently toward the operator. Common causes: wood closing on the blade (prevented by riving knife), fence not parallel to blade (causes pinching), using fence for crosscuts (traps cut-off piece), internal wood stress causing the kerf to close, and letting go of the workpiece before the cut is complete. The riving knife is your primary defense - it keeps the kerf open so wood can't contact the back of the blade. Never remove it unless impossible to make the cut with it in place.

Do I really need a riving knife?

YES. The riving knife is the single most important safety feature on a table saw. It prevents the wood from closing on the back of the blade - the primary cause of kickback. Modern saws have riving knives that rise and fall with the blade height. Only remove it when making non-through cuts (dadoes, rabbets) or when using a dado blade. Reinstall immediately afterward. If your saw came without a riving knife (older models), strongly consider upgrading to a saw that has one or adding an aftermarket splitter.

What table saw should a beginner buy?

For most DIYers, a quality contractor-style saw ($400-700) offers the best balance of capability, portability, and price. Look for: a good fence that stays parallel and locks securely, a riving knife (essential), adequate power (1.5-2 HP), and dust collection ports. If budget allows and you have dedicated shop space, a hybrid or cabinet saw provides better precision and dust collection. Consider SawStop if you want the added safety of flesh-sensing technology. Avoid the cheapest benchtop saws - their fences are usually inadequate for safe, accurate work.

How do I know if my fence is parallel to the blade?

Raise the blade fully and measure from the fence to the same tooth at both the front and back of the blade. Measurements should be identical (or back slightly wider - never narrower). Most fences have adjustment mechanisms to align them. A fence that's closer to the blade at the back causes the wood to pinch into the blade, leading to kickback. Check alignment: when you first get a saw, after any fence adjustment, and periodically during use. Some woodworkers prefer the fence very slightly open at the back (1/64") to ensure wood can't pinch.

What blade should I keep on my table saw?

A quality 40-50 tooth combination blade handles both ripping and crosscutting adequately for most DIY work. If you do a lot of ripping, swap to a 24-30 tooth rip blade for faster, cooler cuts. For finish work on plywood or hardwoods, swap to a 60-80 tooth crosscut blade. Many woodworkers keep a combination blade on by default and only swap for specific operations. A thin-kerf blade is appropriate if your saw is under 2 HP. Always use carbide-tipped blades - they stay sharp much longer than steel.
