Professional circular saw bladesFreud
Professional circular saw blades for ripping softwood and hardwood on squaring saws and multiripping machines.
Application
The LU1C family is designed for ripping and multiripping solid wood, including workpieces with loose knots. Its thirteen variants cover diameters from 250 to 550 mm, bore sizes from 30 to 70 mm and configurations from 22 to 48 teeth.
Technical note
H01K carbide with a 10° ATB tooth geometry and a positive 20° hook angle. Select the exact blade by checking diameter, bore, pin-hole pattern, kerf and tooth count against the machine specifications. The catalogue also provides operating charts for rotational speed and maximum cutting height.

Technical configuration
Shared family specifications, kept separate from the dimensions of each individual code.
H01K carbide, alternate top bevel tooth geometry and positive hook angle.
Specially formulated carbide tips for durability and cutting quality.
Coating designed to reduce friction, heat and material build-up.
Technology designed to reduce vibration and noise.
Anti-kickback design that controls tooth engagement with the material.
Operating parameters
The charts show how the recommended speed and cutting capacity change across the LU1C range.
Rotational speed
The actual speed must remain within the limits of both the blade and the machine.
Cutting capacity
This is a family-level reference; actual clearance and capacity also depend on the machine.
Essential check: before fitting the blade, check its diameter, bore, pin-hole pattern, direction of rotation and the maximum RPM marked on the blade.
Dimensional selector
Filter the variants by the two key dimensions, then compare kerf, plate thickness, tooth count and pin-hole patterns.

Before choosing
Once LU1C has been identified, the exact product code depends on the machine requirements. The portal keeps these two decisions separate.
Permitted diameter, bore and pin holes.
Ripping / Multiripping.
Kerf, plate thickness and tooth count.
Speed and cutting height according to the family charts.
Frequently asked questions
Quick answers for checking the application, compatibility and operating parameters before selecting a product code.
LU1C blades are designed for ripping and multiripping softwood and hardwood, including solid wood with loose knots, on squaring saws and multiripping machines.
Ripping is its primary application. For a cleaner crosscut, choose a family with a tooth geometry and tooth count specifically intended for crosscutting. For LU1C, verify the selected reference within its 250–550 mm diameter and 22–48-tooth range.
Check the machine's permitted blade diameter first, followed by the bore, pin holes or keyways, kerf and tooth count. The dimensional selector narrows the thirteen available codes by diameter and bore. For LU1C, verify the selected reference within its 250–550 mm diameter and 22–48-tooth range.
The d value is the diameter of the central bore. FT and CH identify additional pin holes or keyways; these must also match the machine spindle configuration. For LU1C, verify the selected reference within its 250–550 mm diameter and 22–48-tooth range.
FT01 includes 2/7/42 + 2/9/46.4 + 2/10/60 patterns, while FT02 includes 2/9/46.4 + 2/10/60. The notation specifies the number of holes, hole diameter and pitch-circle diameter. For LU1C, verify the selected reference within its 250–550 mm diameter and 22–48-tooth range.
ATB means alternate top bevel: adjacent teeth are bevelled in opposite directions. On LU1C it is made from H01K carbide and paired with a positive hook angle for efficient ripping.
There is no single speed for the entire family because the recommended RPM range changes with blade diameter. Refer to the operating chart and never exceed the maximum speed marked on the blade or permitted by the machine. For LU1C, verify the selected reference within its 250–550 mm diameter and 22–48-tooth range.
The carbide teeth can be resharpened by a specialist service. The process must preserve the original tooth geometry, angles and blade balance, after first checking the overall condition of the blade. For LU1C, verify the selected reference within its 250–550 mm diameter and 22–48-tooth range.
