How to Choose the Right Bandsaw Blade.docx

How to Choose the Right Bandsaw BladeNOTE: Choosing the right bandsaw blade depends on many factors; including type of bandsaw, condition of bandsaw, what material is to be cut, and how the material will be cut. It is impossible for one blade to work well for every purpose. Some applications need special blades for best results.

Carbon Tool Steel blades are more economical to purchase. Carbon Tool Steel blades will cut mild steel if used at speeds under 200 feet per minute (fpm) for best results, preferably with coolant. If you are sawing in a production setting, your saw is in good repair and adjusted correctly, and want the longest life blade available, then you should use Bimetal bandsaw blades. Bimetal blades cost more than carbon blades, but are generally more economical to operate in the long run, because they can outlast carbon blades by up to 10 times if used properly. Also, they are capable of cutting harder materials, such as stainless steel.金属切割锯带：使用碳钢或双金属锯带从小到大，从水平到立式，金属切割锯带或者使用碳素工具钢或双金属锯带。碳素工具钢锯带更经济。碳素工具钢锯带如果使用在速度低于200feet/min（fpm）切割低碳钢可获得较好的结果，最好带有冷却。假如你正在以批量生产锯切，锯带维修良好，调整适合，想获得寿命较长的锯带，那么你应该使用双金属锯带。双金属锯带成本比碳素钢锯带高，但是在对于长时间运行通常更经济，因为如果恰当使用可比碳素钢锯带寿命长10倍。他们也可切割硬材料，如不锈钢。WOODCUTTING BANDSAWS: Use Carbon Tool Steel, Premium Gold Carbide, or Specialty ResawVertical woodcutting bandsaws from 10” and up will use Carbon Tool Steel blades for most sawing needs. Our Premium Gold carbide impregnated blades are designed to be used either in heavy production or by craftsmen who demand the very best blade available. Our Premium Gold carbide impregnated blades are extremely fast cutting with the longest life of any woodcutting blades we offer - they are quickly becoming the most used and prized blades in the shops of serious woodworkers. Our WoodSaver thin kerf, carbide impregnated resaw blades are specially designed for resawing expensive hardwoods when conserving material is very important. Our Hawc Pro resaw blades are best for general resawing. They cut fast due to their aggressive set and tooth design, and they work well in more inexpensive woods. NOTE: Your owners manual may say that your woodcutting bandsaw can cut metal, but woodcutting bandsaws can only cut soft metals, such as aluminum, brass, copper, etc. Cutting steel could damage your saw, due to the fact that blade speed on most woodcutting bandsaws (average 800 to 3500 fpm) is not slow enough (40 to 200 fpm) for cutting ferrous metals (i.e. steel). Trying to cut steel at woodcutting speeds will ruin the blade due to the extreme heat produced.木材切割锯带：碳素工具钢，Premium Gold Carbide，专业解锯10以上立式木材切割锯使用碳素工具钢可满足大部分锯切需求。Premium Gold CarbideSMALL 2 AND 3 WHEEL TABLETOP WOODCUTTING BANDSAWS: Use The Three Wheeler BladesSmall tabletop saws with 2 or 3 wheels need a very thin blade, such as our Three Wheeler bandsaw blades. The challenge with these saws is that the wheels are so small that a standard thickness blade flexes beyond proper tolerances when it travels around these small wheels, thereby shortening blade life. “The Three Wheeler” bandsaw blades are designed to withstand this extreme flexing and will give you the longest life on these saws.- Return to Top of Page -STEP 2 - CHOOSE A WIDTH: HOW TIGHT DO YOU NEED TO TURN?Horizontal metalcutting bandsaws are typically designed to use only one width of blade. Vertical metalcutting bandsaws and woodcutting bandsaws have the capacity to run a wide range of widths. Here are some minimum turning circle diameters for our most common blades:- Return to Top of Page -STEP 3 - CHOOSE A TOOTH PATTERN: WHAT ARE YOU CUTTING?WOODCUTTING BANDSAWS:There is a wide range of what is considered correct for tooth patterns on a woodcutting bandsaw. The general rule is that fewer teeth per inch provide a faster, but rougher cut; and more teeth per inch provide a smoother, but slower cut.METALCUTTING BANDSAWS:The correct tooth pattern for metalcutting is determined by the thickness (cross-section) of material you are cutting. There should be between 2 and approximately 10 teeth in contact with the material at all times. Generally, choose fewer teeth per inch for thicker materials and more teeth per inch for thinner materials. The chart below will give you some basic guidelines for choosing the correct number of teeth per inch.Solids vs. Structural Shapes:It is simpler to determine the correct tooth pattern for solids than for structural shapes. Structural shapes such as square tubing and angle pieces need to be cut at the correct angle to keep the teeth in contact with the thinner portion of the cut. For example, if you are cutting a piece of 4” angle with a 1/4” wall, you should match the tooth pattern to the 1/4” thickness (10-14 Variable or 14 Raker) and not to the 4” thickness (3-4 Variable or 3 Hoo
