Speeds

Before you begin any bandsaw operation, turn on the Mark V, set the speed according to Table 14-1, and let the bandsaw come up to speed. The speed of a bandsaw is measured by how fast the blade travels, or "Feet Per Minute (FPM)."

The speed is determined by the blade and the material. Generally, slow speeds are used with wide blades to cut hard, thick woods and dense materials. High speeds are used with narrow blades in soft materials.

Table 14-1: Bandsaw Blades and Speeds
Characteristics Recommended Use Recommended Speed**
1/16" Woodcutting Blade* - 24 teeth per inch, 1/32" minimum turning radius For extretmly fine detail work only. Use for wood and plywood up to 3" thick. Not for heavy-duty cuts or resawing. Note: Set the tension scale at 1/8" setting. A (750 RPM, 2160 FPR) for hardwood. B (850 RPM, 2450 FPM) for softwood.
1/8" Woodcutting Blade - 7.5 teeth per inch, 1/4" minimum turning radius For very fine detail work only. Use for wood and plywood up to 3" thick. Not for heavy-duty cuts or resawing. C (950 RPM, 2750 FPM) for hardwood. D (1050 RPM, 3000 FPM) for softwood
1/4" Combination Blade - 6 teeth per inch, 3/4" minimum turning radius A good general purpose blade for wood, plywood, plastics, particle board, and soft non-ferrous metals. Limit resawing to stock 4" thick, metalwork to stock 1/4" thick. This is the blade that comes with your bandsaw. B (850 RPM, 2450 FPM) for hardwood. C (950 RPM, 2750 FPM) for softwood. Slow (700 RPM, 2000 FPM) for other materials.
1/2" Combination Blade - 4 teeth per inch, 2" minimum turning radius For heavy-duty cutting fo wood, plywood, plastics, particle board, and soft, non-ferrous metals. Suitable for resawing stock up to 6" thick, and metalwork in stock up to 1/2" thick. Slow (700 RPM, 2000 FPM) for hardwood, softwood, and other materials.
5/8" Woodcutting Blade - 3 teeth per inch For heavy-duty resawing. Efficiently handles wood up to 6" thick. Straight cuts only. Note: Set the tension scale at the 1/2" setting. Slow (700 RPM, 2000 FPM) for hardwood and softwood

Several blade manufacturers make bandsaw blade stock for a variety of special purposes -- intricate scrollwork, cutting iron pipe, etc. If you need a special blade, you can have it made at a well-equipped commercial saw shop. Use only high-quality blade stock 1/16" - 1/2" wide. Be sure that the finished blade is 72" long, plus or minus 1/2" and that the weld is ground perfectly smooth.

*Caution: Do not use 1/16" blade without special guide blocks. Failure to use special guide blocks will ruin the blade and damage the standard guide blocks. **Note: these speeds are for 60 hz. operations.
