We manufacture and sharpen 2 primary types of High Speed Steel (HSS) Cold Saw Blades for specific applications.
Black Oxide HSS Cold Saw blades (also known as Vapor Treated, VT, or Steam Treated) have a Ferric Oxide surface coating for a longer blade life and reduced galling with steel. They are mainly used for cutting steels on manual and semi-automatic sawing machines. Vapor Treated blades can be used to cut small amounts of non-ferrous metals (like aluminum), but galling may be a problem. VT blades have a dark grey, almost black finish over the entire blade. We sell KINKELDER brand VT blades in all sizes, and our house brand Economy VT blade (asian) in popular sizes.
EC3000 HSS Cold Saw blades by KINKELDER are a cost effective saw blade featuring a very sophisticated, proprietary multi-coating. This special coating and procedure was developed to give the blade exceptional surface hardness and a very low friction coefficient. EC3000 blades offer an excellent price to performance ratio: high performance at an attractive price. EC3000 blades feature a multi-layered orange colored band extending in about two thirds from the edge of the blade. The final coatings are Titanium Carbon Nitride (TiCN).

Tips for Selecting Diameter
Here you choose the correct diameter specified for your machine.
The only exception would be if you need to reduce your blade speed
(also referred to as surface feet per minute, or SFM) on a fixed RPM machine.
If you have a fixed speed machine and need to slow the SFM down,
AND you will be cutting small enough stock,
you can put a smaller blade on the saw than what is called for.
Example: If you have a machine that takes a 350mm blade and runs at 27 RPM,
your blade will be cutting at 97 surface feet per minute.
If you can cut your through your material with a 275mm blade,
your SFM will be reduced to 77 SFM.
This may increase your tool life significantly in some applications
(tough/hard materials like Alloyed Steels or some Stainless Steels).
Tips for Selecting Thickness
Choose other thicknesses to view other choices, pricing and availability
The most popular thicknesses are highlighted in the selections.
A different thickness may cost less due to popularity or ease of manufacturing.
Certain blades are only available in some thicknesses.
A thinner blade will cut smoother and take less power, but may not cut as square. Typically used in thin-wall tubing and other light cuts
A thicker blade will cut more square due to rigidity, but may vibrate more, and will take more power. Typically used in thick-wall pipe, solids, mitering, and heavier cuts.
Tips for Selecting Material Type
Telling us what material you will be cutting allows us to custom grind your blade with the proper angles to maximize performance. We understand that you may not cut only one material all the time, so here are some tips to help you make the best choice.
Harder materials like Mild Steel and Stainless Steel need stronger,
more blunt angles. Blades ground for these materials will also cut softer materials,
but slower than would the proper grind.
Softer materials like Aluminum, Brass & Copper
(although there are some very hard Coppers) need more aggressive angles.
Blades ground for these materials will cut harder/tougher materials, but the blade
will certainly dull faster, and you risk breaking or stripping teeth.
If you cut mostly one type of material, choose that one.
If you cut a lot of materials that fall into both categories above, having blades ground
for each would be the best choice. But if you do decide to cut a lot of material from both
categories above (like Stainless Steel and Aluminum) with the same blade
(NOT recommended) include a note in the comments box during check out as to what you
will be cutting, and we will grind your blades with 'middle-of-the-road' angles.
Tips for Selecting Number of Teeth:
Our exclusive AutoTooth is an industry first!
AutoTooth takes the guess-work out and automatically calculates the correct pitch, tooth count, and grind for you based on your selections of material shape being cut.
Even if you decide to select the number of teeth yourself, you might want to use the AutoTooth feature to compare what you are thinking of using with what is recommended. You may switch back and forth at any time between the two methods with a simple click.
If you regularly cut larger quantities of the same material shape and thickness, consider buying blades dedicated for that use.
If you decide to cut a variety of different material thicknesses with one blade, first use AutoTooth to determine the proper tooth count for each application. Then click 'I want to select the number of teeth myself' and select a number of teeth that is an average for your different applications.
Typically, it is ideal to have about 2-4 teeth engaged in the work at all times (consider both walls when cutting tubing).
Too few teeth may cut faster, but you risk stripping teeth or breaking the blade.
Too many teeth may cut smooth, but your cut time will increase and the blade will dull prematurely.
