Design a circular saw blade

Why

A saw blade is made to its machine: the saw fixes the diameter, the bore, the pinholes and the widest kerf.

How

Open Design, choose the family, set the sizes, teeth and mounting from the machine or the old blade and read the checks and the price.

It opens in the workbench at /app/design/circular-saw-blades.

Families

A PCD tipped blade has its own design module: see Design a PCD saw blade.

What you set

• Family fills a published starting blade so that something is drawn. On a carbide tipped blade Use fills the diameter, kerf, body, bore, teeth, tooth shape and cutting angle of its published row.
• Use is one of: Panel sizing, with a scoring saw; Panel sizing, hard coatings (HPL, CPL); Panel sizing, large diameter; Sizing, table and sliding table saws; Sizing coated board with no scoring saw; Ripping along the grain; Ripping, thin kerf; Cross cutting, optimising saws; Cross cutting, radial and pull saws; Scoring, conical teeth; Non-ferrous and plastic profiles; Non-ferrous and plastics, negative angle; Steel sections, dry cut; Another use.
• Replace every starting size with the machine's or the old blade's before you quote.
• Bore and hub on an HSS blade sets the bore and the hub diameter as a published pair.
• Pinhole pattern holds the published patterns, each against its bore and its machines. A pattern that is not listed is entered as custom with its count, diameter and pitch circle.
• Clearance angles, bevel angles and tip sizes nobody states stay empty. The picture draws them in proportion and says so. They never reach the price or the designation.
• The design module composes the designation line and reads back the tooth pitch.

What is checked

A block stops the design until the value it names is changed. A warning changes nothing and is said out loud. Several warnings call the blade a special: it can be made and the maker confirms it.

Blocks

• A kerf that is not wider than the body of a tipped blade.
• A machine speed above the n max marked on the blade.
• A positive cutting angle on the use for radial and pull saws.
• A tip too short to leave a usable tooth.
• A tip sequence that cannot be read.
• A mounting that does not fit: the bore, a pinhole or a keyway meets another hole or the tooth roots.

Warnings

• Teeth that project less or more over the body than the published rows do.
• A machine speed with no n max to check it against. An n max that gives a rim speed above the published ratings.
• A value outside the published span for carbide tipped blades or outside the row for its use.
• Tips drawn thinner than entered, because the pitch or the top clearance cannot seat them.
• Laser ornaments on a blade too small for them or on a body with no room.
• On an HSS blade: a tooth form that does not suit the pitch or the kerf. A diameter, a kerf or a bore and hub pair that is not in the standard range.
• On a solid carbide blade: a diameter, thickness or bore outside the ISO 2296 series. A pin drive at a diameter the standard does not offer one for.
• A pinhole pattern published for another bore or another family.

The carbide tipped rows are Leitz's published product rows, one maker's range. The HSS range is Kinkelder's standard range. The slitting saw series is ISO 2296, read in its public preview.

How it is priced

The body sheet and tips of a tipped blade and the disc blank of an HSS or solid carbide blade are matched from the stock you hold. Where nothing held fits, the material is priced at the design module's own rate and the result says so.

What it produces

• Customer drawing
• Blade body DXF
• Cutting list with the designation
• Spec sheet
• STEP, STL and GLB

Exports offers a customer drawing, a specification and quote PDF, a cutting list CSV, a DXF, an STL, a GLB and a STEP file.

From a wizard

The recommendation of the circular saw blade wizard opens here with the blade's family, sizes, teeth and mounting set. A PCD recommendation opens the PCD saw blade design module instead.

It hands nothing over where this design module has no family for the answer, such as a two part scoring blade or an HSS slitting saw.

What it does not make yet

The workbench and the specification sheet state its scope in these words: "This module sets out a carbide tipped, HSS or solid carbide circular saw blade, composes its designation line, checks it against the published tables and prices its manufacture. Where no figure is published (clearance and bevel angles, tip size, hollow grind, solid tooth angles) the picture is drawn in proportion and says so: it is not a grinding specification. It does not rate the blade's maximum speed, certify it to EN 847-1 or choose the scoring pair: those stay with the maker and the machine manual. PCD tipped blades have their own module."

• An HSS segmental blade, a friction blade, a two part scoring blade and a carbide or cermet tipped steel cold saw.
• An irregular pitch pattern: the blade is marked for it and its teeth are drawn at an even pitch.
• The chip breaker grind: it is drawn as the curved tooth form.
• Riveted or shaped expansion slots, cooling elements, chip limiters, a hub recess, countersunk pinholes and a tension ring.
• Cutting data: the design module states no speed or feed.

Tolerances, a balance grade, a body hardness and a carbide grade by material are not values here. They go in the quote line's note word for word.
