Betterley Tru-Cut Zero Clearance Table Saw Insert Systems

Betterley Industries produces the Tru-Cut Zero Clearance Insert System, a precision table saw upgrade that replaces the factory throat plate with a snug-fitting insert. By closing the gap around the blade, a zero-clearance insert prevents thin workpieces and narrow offcuts from dropping into the saw, and dramatically reduces tear-out on the underside of cuts through solid wood and sheet goods.

Infinity Tools carries both the Betterley Tru-Cut Zero Clearance Tablesaw Insert System and the companion Replacement Inserts for Betterley Tru-Cut Insert Systems (4-Pc). Having spare inserts on hand means you can keep dedicated inserts for standard crosscuts, dados, and angled cuts without resetting a single insert each time.

Why Upgrade to a Zero Clearance Insert?

Reduces or eliminates blow-out on veneered plywood and hardwood faces
Supports narrow workpieces that would otherwise tip into the standard opening
Improves operator safety by minimizing the gap near the blade
Allows dedicated inserts per blade type — standard, kerf, dado

For woodworkers focused on clean joinery and furniture-quality surfaces, a zero-clearance insert is one of the highest-value table saw upgrades available. Pair the Tru-Cut system with quality carbide router bits from Infinity Tools for a complete precision cutting setup.

Frequently Asked Questions

What is a zero-clearance table saw insert?

A zero-clearance insert is a custom throat plate that fits tightly around the saw blade, leaving only a thin kerf opening rather than the wide slot of a factory plate. This support eliminates tear-out on the underside of cuts and prevents narrow offcuts from falling into the saw.

What is the Betterley Tru-Cut system?

The Betterley Tru-Cut Zero Clearance Tablesaw Insert System is a precision throat plate replacement that installs in most standard table saw insert openings. It comes with a blank insert that the user scribes to fit and then cuts with the saw blade to create a perfect zero-clearance kerf.

How many replacement inserts come in the Betterley 4-piece set?

The Betterley Tru-Cut Replacement Insert Set includes 4 blank inserts, giving you enough to dedicate separate inserts to a standard rip blade, a crosscut blade, a dado stack, and angled cuts — without having to recut a single insert each time you change setups.

Will the Betterley Tru-Cut insert work with my table saw?

Betterley Tru-Cut inserts are designed to fit common table saw insert dimensions. Check the product listing for exact specifications and compatible saw models; if you have questions, contact the Infinity Tools team through the contact page.

Does a zero-clearance insert help with cutting plywood?

Yes. Plywood veneers are especially prone to tear-out on the face that contacts the blade exit side. A zero-clearance insert supports the wood fibers all the way to the blade, significantly reducing or eliminating this blow-out on finish-grade and cabinet-grade plywood.

Can I use a zero-clearance insert with a dado blade stack?

A dado-specific zero-clearance insert requires its own kerf since dado stacks cut a much wider groove than a standard blade. The Betterley system supports this by letting you dedicate one of your blank inserts to a dado stack, which you cut separately from your standard-blade inserts.

Is a zero-clearance insert safer than a factory throat plate?

Zero-clearance inserts improve safety by reducing the open area around the blade, which lowers the risk of thin workpieces tipping into the gap and catching on the blade. They are widely recommended by woodworking instructors as a standard safety upgrade for the table saw.

What is Infinity Tools' return policy on Betterley products?

Infinity Tools' standard quality and return terms apply to Betterley products. Visit the Quality Guarantee page for full details on returns, exchanges, and satisfaction policies.

How do I create the kerf in a blank zero-clearance insert?

After fitting the blank insert flush in the table saw opening, raise the blade slowly through the insert while it is held down with the saw guard or a hold-down. This scribes a perfectly aligned kerf. Refer to the Betterley instructions or the Infinity Tools learning resources for step-by-step guidance.

What other precision table saw accessories does Infinity Tools carry?

Infinity Tools carries several precision table saw accessories, including the Precision Miter Bar for crosscut sleds and tapering jigs, and the Thin Rip Guide for safely cutting narrow strips. These complement a zero-clearance insert for an upgraded table saw setup.
