Knife Material

WEINIG CORRUGATED KNIFE MATERIAL

SRS HIGH SPEED STEEL - Short runs of up to 1000 LF in hardwoods; up to 3000 LF in softwoods. Easy to rough grind with 54 grit Grinding Wheels (Aluminum Oxide) and finish grind with either 100 grit Ceramic Grinding Wheels or CBN (Cubic Boron Nitride) Grinding Wheels

M3+ HIGH SPEED STEEL – Weinig standard knife steel used in both hardwood and softwood applications. Longer run times that with industry standard M2 knife steel. Easy to rough grind with 54 grit Ceramic Grinding Wheels (Aluminum Oxide) and finish grind with either 100 grit Ceramic Grinding Wheels or CBN (Cubic Boron Nitride) Grinding Wheels

SUPRE-18 HIGH SPEED STEEL - Extra tough knife steel for use on long runs (up to 5000 LF) in extremely hard wood species, such as Maple, Hickory and imported exotics. Also works well with Soft Maple mineral streaks. Easy to rough grind with 54 grit Ceramic Grinding Wheels (Aluminum Oxide) and finish grind with either 100 grit Ceramic Grinding Wheels or CBN (Cubic Boron Nitride) Grinding Wheels.

TCT – Carbide tipped knife steel for use on long runs (up to 50,000 LF) of highly abrasive hardwoods, composite wood products, wood with glue lines and synthetic materials. Best if rough ground with a Diamond Grinding Wheel designed for grinding carbide and tool steel simultaneously and finish ground using a Diamond Grinding Wheel designed for finish grinding carbide knives.

DOUBLE BACK CARBIDE – A harder grade of Carbide for use for extremely long runs (50,000+ LF) of clear (not knotty) highly abrasive hardwoods, composite wood products, wood with glue lines and synthetic materials. The backers are rough ground using a 54 grit Ceramic Grinding Wheel (Aluminum Oxide) finish ground using a Diamond Grinding Wheel designed for finish grinding carbide knives.

Being knowledgeable and selective in choosing your steel types can help you improve the finish of your products and save you time and money.

As you gain experience running different types of material, you will build an understanding as to how well some knife steels will work for you in your production. For instance is you have a 300 LF run of poplar in a small band moulding to produce, then the SRS High Speed Steel would be just right for the job. Now if you had that same job to run but the material was to be teak or an exotic hardwood, then TCT or Double-Back Carbide would be the correct choice for your tooling.

Keeping accurate records of the steel types you run and the results you find from the variety of different materials you will be using will pay dividends to you and your company now and in the future.
