Key Features

OEM Replacement Fit Built as the original equipment replacement blade for Freud JS100 and JS102 biscuit joiners, so you can get your joiner back to cutting proper slots without guessing on fit. Carbide Cutting Edge Six Super Micrograin Carbide teeth are built for long life. That matters on a biscuit joiner blade because a clean, consistent slot is what keeps joints fitting the way they should. Right Size Setup With a 4 in. blade size and 22 mm bore, this Freud FI100 4 in. 6-Tooth Replacement Blade is made for biscuit joiners that need this specific arbor and blade format.

Overview

The Freud FI100 4 in. 6-Tooth Replacement Blade is a replacement biscuit joiner blade for restoring cutting performance on compatible plate joiners. This is a replacement biscuit joiner blade designed for cutting biscuit slots in wood. Model Number: FI100. If your current blade is dull, slowing the tool down, or leaving rough slots, this is the part that gets the machine working like it should again.

Freud lists the FI100 as the original equipment replacement for the JS100 and JS102, and also notes compatibility with many similar biscuit joiners. The 4 in. class blade size, 22 mm bore, and 6-tooth layout are the key numbers here. On a biscuit joiner, correct diameter and bore matter just as much as sharpness because the tool is built around that blade geometry. Get those right and you get clean, repeatable slots that let biscuits seat properly and joints pull together without fighting alignment.

This blade uses six Super Micrograin Carbide teeth for long service life. That matters more than it might on a general-purpose saw blade because biscuit joiners do one very specific job: plunge quickly, cut a clean slot, and retract without tearing up the workpiece. A carbide-tipped replacement blade helps keep cuts smooth in hardwood and softwood while holding its edge longer than a basic steel cutter. Freud also calls out a kickback-reducing design, which is a practical benefit when you want the plunge to feel controlled instead of grabby.

The FI100 is a straightforward part, but it is the kind of part that can make an older tool feel useful again. When a biscuit joiner starts leaving burned edges, fuzzy slots, or feels like it is working harder than it should, the blade is usually where you start. Swapping in the right replacement blade is often faster and smarter than trying to work around poor cuts or forcing a worn blade through finish work, cabinet parts, face frames, or panel glue-ups.

This Freud replacement blade is aimed at woodworkers, cabinet installers, trim carpenters, and serious DIY users who already own a compatible biscuit joiner and want the correct replacement part instead of a maybe-it-fits substitute. If you use a plate joiner for edge joining, alignment during panel glue-ups, or cabinet casework, this is the kind of accessory that directly affects cut quality and how easily the rest of the job goes together.

Get Your Biscuit Joiner Cutting Clean Again

A biscuit joiner only works as well as the blade in it. The Freud FI100 is built to replace worn cutters on compatible joiners so you can get back to accurate slot cutting for wood joining and panel alignment.
