Professional circular saw bladesFreud
Freud LU4D professional circular saw blade family with 3 verified configurations from 250 to 350 mm.
Application
The LU4D range includes 3 configurations, with diameters from 250 to 350 mm, bore sizes from 30 to 30 mm and tooth counts from 80 to 108. Use the dimensional selector to identify compatible codes, then compare kerf, plate thickness and pin-hole pattern.
Technical note
H01K carbide, Triple chip grind (TCG) tooth geometry, 5° tooth angle, 5° hook angle. Check blade diameter, bore, flange or pin-hole pattern and maximum RPM against the machine specifications before fitting.

Technical configuration
Shared family specifications, kept separate from the dimensions of each individual code.
H01K carbide, Triple chip grind (TCG) tooth geometry, 5° tooth 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.
Operating parameters
The chart shows how the recommended speed changes across the LU4D range.
Rotational speed
The actual speed must remain within the limits of both the blade and 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 LU4D 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.
Cutting polymeric materials.
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.
LU4D is designed for Cutting polymeric materials. Its suitability must be checked against the material, machine and exact variant specifications.
The family is specified for Polymeric materials. Material density, coating, thickness and condition can affect the resulting edge quality. For LU4D, verify the selected reference within its 250–350 mm diameter and 80–108-tooth range.
The catalogue specifies Squaring saws, Table saws, Mitre saws. Before fitting, check diameter, bore, flange or pin-hole pattern and the permitted maximum speed. For LU4D, verify the selected reference within its 250–350 mm diameter and 80–108-tooth range.
The family uses Dente piano trapezio 5° tooth geometry. Refer to the technical note for the carbide grade and hook angle. For LU4D, verify the selected reference within its 250–350 mm diameter and 80–108-tooth range.
There are 3 variants, with diameters from 250 to 350 mm, bores from 30 to 30 mm and tooth counts from 80 to 108. For LU4D, verify the selected reference within its 250–350 mm diameter and 80–108-tooth range.
For LU4D, start with the machine bore (30–30 mm) and the required diameter (250–350 mm). Then select within the available 80–108-tooth range by comparing kerf, plate thickness and any pin holes or keyways.
The correct speed for an LU4D blade depends on the selected diameter, which ranges from 250 to 350 mm, and on the machine. Never exceed the lower of the maximum RPM marked on that blade and the machine manufacturer’s limit.
A specialist can assess and resharpen the Dente piano trapezio carbide teeth used by LU4D, provided the blade body is undamaged. The original geometry, angles and balance must be preserved; the number of possible services depends on the condition of the selected reference.
