Infinity Tools saw blades are designed to offer superb cuts, reliable performance and extended cutting life. We achieve this by manufacturing saw blades that only use the highest quality materials, manufacturing techniques and employ advanced design.
Premium quality saw blades begin with the finest raw materials:
Hot-Rolled Steel For Optimum Strength
Premium Steel Body |
|
Hot-Rolled steel plates are uniformly strong throughout, making them an ideal foundation for our premium quality saw blades. Inferior quality competitor blades use cheaper Cold-Rolled steel. |
We only use Hot-Rolled steel for the production of our circular saw blades. Inferior quality saw blade manufacturers will use cold-rolled steel since it is cheaper and faster to machine. But the process of cold-rolling creates a steel plate which does not perform under the stresses of woodworking. Conversley, Hot-Rolled steel is pressed at a temperature where the plasticity of the steel is still high. This allows the material to maintain ductility, providing resistance to deformation and forming the ideal foundation for our premium quality saw blades.
Premium Micro-Grain Carbide Tips
Micrograin Carbide Teeth |
|
Micrograin carbide tips come from the leader in Sintered Carbide technologies. This quality insures the longest time betweeen sharpening and the cleanest cutting saw blades possible. |
A circular saw blade is only as good as its cutting edges. That’s why we only use micrograin carbide tips from Ceratizit, the leader in sintered carbide technologies. Their exclusive SinterHIP sintering process make it possible to obtain a premium virgin grade of carbide that is practically free of porosity. A carbide tooth which is non-porous will resist cracking much better than once produced with a lower cost process. We use this premium carbide on all of our woodworking saw blades so you can be sure they will go the distance in your shop or on the job site.
State-Of-The-Art Manufacturing & Advanced Saw Blade Design:
Hi-Tech Construction Technique
Precision laser cut saw blade plate - We use a very precise C.N.C. laser cutting machine to accurately form each blade body. This advanced manufacturing technique allows us to produce a saw blade body that is 5x more accurate than one that comes out of a high-volume press or mold. Laser cutting is the ideal method for making blade bodies since it’s possible to cut the plate within tighter tolerances and to use higher-quality steel plates during the production process.
Thermal heat treatment - A blade plate that contains stresses and molecular non-uniformity will distort and warp when cutting wood. To avoid these potential problems, each of our saw blade plates undergoes a complex annealing process in a closley controlled computerized oven. This extra step in our quality process relieves internal stresses while making the saw blade resitant to warping when working. The end result is a saw blade that runs true and free of distortion when cutting wood.
Flattening of the plate and hand flatness testing - A critically important step in making a premium quality blade is to ensure it's flatness. A blade that is not flat will not cut well. We have a special machine that ensures each saw blade plate is flat to within .002”. Once flattened, each plate is then checked by hand to ensure its parallelism and planarity to within (± 0,01mm). Each saw blade plate must fall within these very tight tolerances or the body is reworked and checked again.
Tension of the plate and hand tension testing - Blade bodies spinning at 8000 r.pm have a tendency to warp or distort under this immense pressure. Tensioning a blade body allows it to stay true while spinning on your saw and minimizes runout. It is an essential part of our quality production process and done properly, it ensures maximum performance in each of our saw blades.
Carbide brazing - We use a special Tri-Metal brazing material which forms an unbreakable bond between the steel plate and the micro-grain carbide tooth. The Silver component of this braze material melts at a lower temperature and thus allows us to introduce less stress during the brazing process. Our fully automatic brazing stations are aided by lasers to obtain perfect tip placement on the steel body and the strongest joint possible. Another important feature of tri-metallic alloy is that it acts as a shock buffer and substantially reduces the effect of the micro-impacts that the cutting edges take during operation. This leads to longer tooth life and increased time between sharpening.
Nickel-Armor or Teflon coating - Nickel Coatings have long been prized for their strength and durability in high tech industries. In fact, the Aerospace industry coats aircraft parts, including engine components and landing gear pieces with Nickel because of its excellent lubricity, wear resistance and anti-corrosive properties. These properties are exactly what you want in a top-quality saw blade which is why we are proud to exclusively offer Nickel-Armor coatings on all of our woodworking saw blades.
Carbide Grinding - Carbide grinding is arguably the most important part of producing a top-quality saw blade. Experience has shown us that the sharper a tool is, the longer it will last and the cleaner it will cut. This is why we employ an array of 5-Axis C.N.C. carbide grinders equiped with high-pressure oil cooling and extra-fine diamond grinding wheels . These special machines allow us to apply a final mirror-finish grind on each carbide tooth that ensures the sharpest and longest lasting cutting edge possible.
