Types

my desktopFlat Top (FT):
Typically used for ripping (cutting with the grain) softwood and hardwood.

    Advantages:
    • It cuts both sides of the kerf simultaneously, making it twice as effective as teeth in a staggered tooth saw in which each tooth cuts only one side at a time.
    • Its balanced cutting forces reduce saw body stresses.
    • It has large included angles between cutting edges that strengthen the tooth form and keep it sharp for longer periods of time.
    • The tooth form is relatively easy to maintain.
    Disadvantages:
    • The tooth form generates relatively large cutting pressure and this contributes greatly to chip out or tear out at the exit point on the material.
    • Low side clearance angles inhibit the freedom of chip flow. The chips generated in the cut drag on the side of the cut causing a buildup.


my desktopAlternate Top Bevel (ATB):
Typically used for general purpose / combination and and crosscut saw blades

    Advantages:
    • It produces very low cutting pressures that almost eliminate the tendency to tear out.
    • The chips fall free in the chip spaces created by the large side clearance angles.
    Disadvantages:
    • The leading point is susceptible to wear and damage from shock loads.
    • Cutting forces perpendicular to the beveled edge result in semi-lateral thrusts on the saw body.
    • When sharpening, it is difficult to maintain an equal bevel and equal diameter across the points of the teeth around the saw.


my desktopHi-Alternate Top Bevel (HI-ATB):
Higher top bevel grind and longer teeth than standard ATB blades. Specially designed for cutting acrylics and formicas or melamine with chip free results.

extra fine chipless sawing on acrylics and formicas or melamine where a scoring unit is not used
    Advantages:
    • Gives an extra fine cut.
    • Perfect blade to cut man-made materials when a scoring unit is not used.
    • The chips fall free in the chip spaces created by the large side clearance angles.
    Disadvantages:
    • The leading point is extremely susceptible to wear and damage from shock loads.
    • Can not be used for solid wood sawing, as the intermittent cutting resistance can cause tooth breakage.
    • Cutting forces perpendicular to the beveled edge result in semi-lateral thrusts on the saw body.
    • When sharpening, it is difficult to maintain and equal bevel and equal diameter across the points of the teeth around the saw.


my desktopTriple Chip (TCG):
The 45º Teeth do the cutting and the flat tooth is a raker for chip cleanout. Triple Chip Grinds combine a balanced cutting force, low tooth drag and free chip flow. This blade can be used to cut Melamine, Plastics, Formica®, other materials that are subject to chipping.


    Advantages:
    • Large inclined angles in the cutting edges give the triple chip form good wear resistance.
    • A balanced cutting force.
    • Low tooth drag.
    • Free chip flow.
    Disadvantages:
    • The triple chip tooth form requires extra maintenance care to avoid the risk of changing tooth forms during sharpening. Alterations can lead to deteriorated cutting action.
    • The triple chip tooth form has strong blunt edges, there is a relatively low shear generating high cutting pressures which tend to produce chip outs.


my desktop4 Tooth and Raker (4&1):
Used on General purpose / combination blades. Rips and crosscuts equally well and provides a very smooth cut.


    Advantages:
    • It produces very low cutting pressures that almost eliminate the tendency to tear out.
    • The chips fall free in the chip spaces created by the large side clearance angles.
    • A balanced cutting force.
    Disadvantages:
    • The leading point is susceptible to wear and damage from shock loads.
    • In sharpening it is difficult to maintain an equal bevel diameter across the points of the teeth around the saw.


my desktopConical Form:
Used on scoring blades.



    Advantages:
    • Large included angles in the cutting edges give the triple chip form good wear resistance.
    • A balanced cutting force.
    • Low tooth drag.
    • Free chip flow.
    Disadvantages:
    • The triple chip tooth form requires extra maintenance care to avoid the risk of changing tooth forms during sharpening. Alterations can lead to deteriorated cutting action.
    • The triple chip tooth form has strong blunt edges, there is a relatively low shear generating high cutting pressures which tend to produce chip outs.
