5 Select the Right Band Saw Blade in Six Steps (continued) 3 Tooth Rake Straight (Zero), Positive, or Heavy Set* Rake Positive Straight (Zero) *Available with Emperor for cutting heavy beams and bundles. 4 Tooth Shape: Regular A conventional tooth used for general purpose sawing, straight or zero rake. Gladiator Large teeth, up to 12º positive rake angle, for optimum production cutting of steels up to 42 HRc, stainless, nickel based and nonferrous alloys Hook A positive rake for fast cutting of nonferrous metals and non-metallics Skip Zero rake and shallow gullets for cutting large sections of soft, nonferrous material. 5 Type of Pitch: Constant All teeth on the blade have uniform spacing, gullet depth, rake angle throughout the full length. Typically for general purpose cutting. Identified by one pitch number. Variable Size of tooth and depth of gullet varies to substantially reduce noise levels and vibration. Helps cut all structurals, tubing and solids smoothly and quickly. Identified by two pitch numbers. 6 Pitch (Teeth-per-inch) Pitch is generally regarded as the number of teeth per inch or 25mm. Cutting thinner sections requires a finer pitch (more teeth per inch /25mm). Thick sections require coarser pitches (less teeth per inch/25mm). The charts are good guidelines. Feeds and Speeds Starrett has a Band Saw Blade Selection Slide Chart available by request for a quick reference to the optimal feeds and speeds Band Saw Blade Break-In Procedures The proper break-in of a bi-metal blade assures longer blade life, faster cuts for a longer period of time and consistent performance. Refer to the slide selection chart for proper feeds and speeds. Easy-to-cut material such as carbon steel and aluminum Run the normal surface feet per minute (SFM). Adjust the feed pressure to about one-half the normal cutting rate for the first few cuts or for square inches ( sq. cm). Increase to the normal rate. Because the cross section limits in the chart are broad and overlap, choose a coarser pitch if the speed of cut is most important. Choose a finer pitch if finish is most important. Variable Pitch Selection Cross Section Thickness To Be Cut Inch mm Use Variable Pitch 7/32-7/8 6-22mm /4-1 1/ mm /32-1 1/2 9-40mm / mm /2-2 3/ mm mm / mm mm mm and Over 200mm and Over Constant Pitch Selection Cross Section Thickness To Be Cut Inch mm Use Constant Pitch 32 (Anything Thinner Than Up to 5/16 Up to 8mm a 1/8 (3.2mm) Cross Section Should Be Angled to the Blade) 5/32-1/2 4-13mm 24 7/32-5/8 6-16mm 18 1/4-7/ mm 14 3/8-1 1/ mm 10 1/2-1 1/ mm mm 6 1 1/ mm mm mm 2 4 1/ mm 1 1/4 8 and Over 200mm and Over Hard-to-cut materials such as nickel-based alloys like Inconel, hardened steels, tool steels and stainless steels Run the normal surface feet per minute (SFM). Adjust the feed pressure to about three-quarters of the normal for the first few cuts or sq. inches, increase the cutting rate part way to normal for the next few cuts, then increase to the normal cutting rate. Avoid vibration. NOTE: Be sure to remove chips on these types of materials.

23 Carbide Grit Bands These band saw blades will easily cut through most hard and abrasive materials. Starrett carbide band saw blades are especially useful in cutting new and complex materials such as composite graphite, fiber-reinforced plastics and titanium. In some cases, they cut better than regular blades. In other cases, they re the only blades that will cut when a regular band can t. Use Carbide Grit Band Saws : For material 1/4 (13mm) in thickness and above, use gulleted blades Where surface chipping is possible or on brittle materials or material thicknesses less than 1/4 (13mm), use continuous edge blades Coarse grit is applicable for faster cutting of thick materials or metals Finer grit is applicable on thin materials and fine finishing Minimum machine wheel diameter of 24 (600mm) is recommended for continuous band. Smaller diameters tend to increase fatigue and reduce blade life Use widest applicable blade for straight cutting 30% reductions in cut radius can be achieved using grit blades instead of standard blades EDP No. Offered in 100 and 250 (30 and 76m) Coils Width x Thickness Fine Grit Medium Grit Medium Coarse Grit Coarse Grit Inch mm Tooth Type /4 x x 0.50mm Gulleted /8 x x 0.65mm 1/2 x x 0.50mm 1/2 x x 0.65mm 3/4 x x 0.80mm 1 x x 0.90mm Gulleted Continuous Gulleted Continuous Gulleted Continuous Gulleted Continuous Gulleted Continuous x x 1.10mm Gulleted /4 x x 0.90mm Coolants are needed for most metal cutting and should be considered for glass and ceramics Start cuts at lower speeds and gradually increase until the required performance is achieved Gulleted Continuous /4 x x 1.10mm Gulleted Bands furnished in coils as listed or available welded, cut to length and ready to use.
