Blade Selection (TPI)
The selection of the best blade configuration (see the table below) is
necessary for optimum cutting performance.
• Correct blade choice is primarily dependant on two factors: material
thickness and material type.
• Greater TPI should be selected as material thickness decreases.
• However, if the TPI is too great, the tooth loading will be insufficient to
enable penetration; and cutting. The teeth will also rapidly lose
their sharpness.
• For thicker material a lower TPI should be used otherwise the gullet will
not be sufficient to clear the waste and the blade will stall or burn
the wood.
The accompanying blade selection chart (see the table below) gives
guidance on the TPI that should give the best results when cutting a
variety of material types and thickness. (See the table below) provides
recommendations on selecting the correct blade for a variety of commonly
used materials. If in doubt about any aspects of blade selection contact
Customer Services on 01246 561 520 for assistance.
The table provides a guide to selection only. Exact tooth configurations
are not always available, nor are all blade configurations covered, but the
principles remain the same.
For special applications, custom blades can be supplied please call
Customer Services on 01246 561 520 and we can advise you accordingly
on your specific needs.
