Jonsereds Cutter for Planing of Wooden Profiles

Precision Tool
Jonsereds cutters are precision tools with a long working life.  The whole length of the tip can be used and its profile remains the same after regrinding until the cutter is worn out.  Even composite cutters (with setting adjustment screws) do not require any adjustment after re-grinding.  This has been achieved by the development of a special curve on the tooth back and helical side clearances.  It is therefore essential that the cutter is correctly used and maintained so that these excellent characteristics will be maintained.  Regular cleaning, grinding and honing will increase the working lifetime of the cutter considerably, and maintain a high standard of finish throughout the mill.

Tungsten Carbide Tipped Cutters
These are more suitable for very dry timber, hardwood or very abrasive applications such as rounding of edges.  The carbide gives longer edge life than High Speed Steel.

Waco - Jonsereds V-Grooved Back Type
The knives in these cutterheads have a single large v-groove in the back.  The face projects forward, giving a thick knife designed for easy sharpening by face grinding.   The profile is made when the knife is supplied by the customer.

Serrated Back Knife Type
These profile cutterheads can be supplied with either HSS or carbide tipped serrated back knives.  The knives have to be sharpened on the backs, i.e. in a profile grinder.

Thin planer knives are available in three different materials: normal quality, high speed steel 2722 and carbide tipped.  Carbide is recommended for longest standing times and for more abrasive applications (e.g. glue lines).
