Page 8: General Information
Table of radii inch Types of Set The set is the tilt, or angle, given to the teeth of the saw blade to provide clearance for the blade body and the tooth edges. Below are different types of set: Raker set In the raker set, one tooth is set to the left, one tooth is set to the right, and one tooth (raker) is unset. - Page 9 This is because the penetration capacity of each individual tooth is greater if the saw’s feed pressure is distributed over a fewer number of teeth. A coarse pitch (few TPI) therefore increases productivity and provides a desirable, large chip space.

- Page 11 Tooth pitch for solid workpieces The diagram below will help you select the right pitch for cutting solids. The ideal choice is at the widest point of each field. Example 1: When cutting a Ø 6 inch (150 mm) bar, use 2 TPI, if an evenly pitched blade is your choice.
- Page 12 General Information Cutting pipes and profiles The diagram below will help you find the right tooth pitch for cutting pipes and profiles. The recommended tooth pitch for cutting profiles is found in the field where the width meets the wall thickness of the profile. Example 3: When cutting a 4"...
- Page 13 Tooth Shape guide Metal Cutting (Evenly pitched) The tooth shapes have different rake angles, clearance angles and gullet depths. This makes each tooth shape suitable for a specific application. Regular is a standard tooth shape with 0˚ rake angle. Regular is the traditional tooth shape for general cutting of small, solid workpieces.
