Ridge Carbide Triple Play Box Joint Blade Set

The Triple Play is another great value in Ridge Carbide’ long line of top-quality cutters – tight tolerances, extreme sharpness, and a moderate price. It’s adjustable like a stack dado but cuts like dedicated flat-topped box joint blades. Kerf adjustable from 3/16” – 7/16” and micro-adjustable with included metal shims. Note: Designed for box joints and long-grain grooves only – use a conventional dado set for cross-grain cuts. Made in USA.

Ridge Carbide Triple Play Box Joint Blade Set
5/8” Arbor, 3/16" to 7/16" Width

You’ll see Ridge Carbide blades place 1st or 2nd in comparison tests that include them, and they’ve been working factory-direct with commercial shops and hobbyists for standard & custom blades, custom cutters, and sharpening since 1970.

With box joints’ growing popularity, the US-made Triple Play blade set is your missing link – it merges the adjustability of a stack dado with the lower price and cut quality of dedicated flat-topped box joint blades.

Ridge Carbide’s tight tolerances and extreme sharpness will produce clean, flat bottom grooves with NO “bat’s ears” in the corners like conventional stack dados.

The Triple Play is also perfect for cutting grooves along the grain, like the slots for drawer bottom panels… if you’re facing a big stack of drawer parts, you’ll appreciate your table saw’s speed advantage over your router.

Important: This blade set is designed for ONLY cutting box joints and cutting grooves & rabbets along the grain. Use a conventional dado set for the best results from cross-grain cuts.

The Triple Play set is loaded with features:

Quickly sets up for 5 kerf widths: 3/16” – 1/4" – 5/16" – 3/8" – 7/16".

The included metal shim kit lets you tweak the kerf width…if you’re cutting box joints with the INCRA I-Box or other step-type box joint jigs, the adjusting shims give you more flexibility in matching the cut pattern to the board width.

Extra-thick C-4 carbide tips let you sharpen the set 20-25 times.

4-piece set is shipped in a cardboard storage case
. Made in USA.

Quick Tip: Ridge Carbide’s sharpening service is the best in the business…do yourself a favor and don’t send your blades anywhere else for service.
