Types
Flat 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.
- 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.
Alternate 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.
- 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.
Hi-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.
-
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.
- 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.
Triple 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.
- 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.
4 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.
- 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.
Conical 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.
- 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.
