Track Saw Blade Size, Arbor and Kerf: Fit Checklist
A track saw blade must match more than diameter. Arbor size, cutting width, plate thickness, rated speed and the saw’s blade requirements all matter. A blade checker can flag an obvious mismatch, but it should never declare a blade safe solely because two dimensions match.

Inspect the relevant offer
The retained blade offers are seller listing records only. A title-level brand, diameter or bore match does not verify kerf, plate thickness, speed, tooth form, material application or exact saw generation; confirm every required value in current manufacturer documentation.
Milwaukee 48 Teeth Fine Finish Track Saw Blade, 165 mm Blade
Check Amazon offerRead the complete blade requirement
Start with the exact saw model and its current manual. Record blade diameter, arbor diameter, permitted cutting width or kerf, any plate-thickness requirement and the required speed rating. Include the intended material and cutting mode. A nominal six-and-a-half-inch label is not a substitute for the specified metric dimensions. Makita's B-07353 illustrates the complete check: 6-1/2-inch diameter, 20 mm arbor, 0.087-inch kerf, 0.062-inch plate, 9,250 rpm maximum, 48 ATB teeth and a named SP6000J application. If a candidate blade or marketplace record omits one of the values your saw requires, leave that field unresolved rather than turning a partial match into approval.
Kerf and plate thickness describe different things
Kerf is the width removed by the cutting teeth; plate thickness describes the steel body behind them. On a saw with a riving knife, those dimensions must maintain the relationship specified in the manual. The DEWALT DCS520 and DWS520 make the risk concrete: both manuals specify 165 mm diameter, 20 mm bore, at least 6,000 rpm and a plate no thicker than 1.6 mm, but the DCS520 requires at least 1.8 mm kerf while the DWS520 requires at least 2.2 mm. The Milwaukee 2831-20 instructions likewise require the blade body to be thinner than the knife and the cutting width to be wider. Do not remove or alter a riving knife to accommodate an unsuitable blade.
Festool generations show why model names matter
Festool's compatibility chart provides an unusually clear generation stop rule. TS 55 R made from 2012 through April 2021 and TSC 55 made from 2014 through April 2021 use the 160 x 2.2 x 20 mm blade family. TS 55 F and the TSC 55 KEB listing use the 160 x 1.8 x 20 mm family, and Festool bars those 1.8 mm blades from the older 2.2 mm tools. Do not flatten every newer TSC 55 into that supplied-blade line: the TSC 55 KSEB Basic 577991 product page lists a 160 x 1.6 x 20 mm FWWW35 blade, while Festool's individual 1.8 mm fine-cut and laminate pages also name TSC 55 KS applications. Its table separately assigns TS 60 K and TSV 60 K to 168 x 1.8 x 20 mm blades and does not list the 160 mm family for those saws. Read the exact item, blade record and generation before treating a shared bore as compatibility.
Teeth and material come after mechanical fit
Once a blade meets the saw's requirements, choose the maker's intended application. Festool separates WOOD FINE CUT for clean crosscuts in solid wood, laminated or veneered sheet goods; WOOD UNIVERSAL for wood, wood materials, building panels and soft plastics; WOOD RIP CUT for lengthwise solid-wood cuts; and LAMINATE/HPL for laminate and melamine-resin-bonded panels. Those are application families within its compatibility table, not universal promises attached to tooth count. Makita's B-07353 is a separate 48-tooth ATB example listed for hardwood, fine crosscut and melamine with the SP6000J. Mechanical fit and material approval must both pass.
What a responsible blade checker should display
A responsible shopping workflow reports mismatched known values and lists unresolved requirements. It can record that diameter and arbor match while still requiring confirmation of kerf, plate thickness, speed, generation and application. It should not round 160 millimeters into 165, convert 5/8 inch into 20 mm, or treat a missing field as zero. The site's Blade Finder filters retained listings by brand or title; it does not certify dimensions. The Metabo HPT C3606DPA is a practical example: its manual specifies a 165 mm blade with a 16 mm hole, so a generic 165 x 20 mm suggestion fails even before kerf and material checks.
After changing blades, recheck the cutting reference
Disconnect power and follow the exact blade-change procedure, using the specified hardware and orientation. Never substitute an improvised arbor reducer or mounting arrangement. After installation, check the relationship between the new blade and rail splinter strip according to the system instructions. A different approved blade may require a renewed test cut before the strip can be trusted as the cut-line reference. Inspect the result on scrap that represents the project material before cutting parts to finished dimensions.
Questions about Track Saw Blade Size, Arbor and Kerf: Fit Checklist
Are all 6-1/2-inch track saw blades interchangeable?
No. Verify the exact diameter, arbor, kerf, plate thickness, speed rating and application required by the saw. Similar nominal size does not establish a safe mechanical match.
Can I put a thinner-kerf blade on my track saw?
Only where the manufacturer supports it for that exact model, item and generation. Festool excludes its 1.8 mm blades from the older 2.2 mm TS 55 R/TSC 55 system, while the current KSEB item also shows why a broad TSC 55 K label is insufficient: its supplied blade is documented as 1.6 mm.
Does matching a 20-millimeter arbor prove fit?
No. Arbor size is one requirement among several. A checker should show any remaining unknowns and mismatches rather than convert a partial dimensional match into full compatibility.
