There's a DoALL band saw blade to increase productivity on any sawing job.
use on contour or cut-off machines, this blade features a hard edge and flexible back. Blade Metal Master Page 16 For friction sawing of ferrous metals on contour machines at band speeds of 6000 fpm (1830 mlmin) or higher. Cut- ting edge is heat treated for maximum wear resistance at high sawing velocities, and its teeth are set heavier to in- crease heat buildup while maintaining proper clearance for the back of the band. Blade Page Friction 17 Special Application Band Machine Tools DoALL offers a variety of special application band machining tools which are described in the second sec- tion of this booklet. These tools include knife bands, file bands, tungsten carbide bands and others. For more spe- cific information on these specialty tools, their machine and coolant requirements and their specific applications, see full descriptions beginning on page 23.
There are two basic considerations for selecting a band tool. The first is to determine the proper blade type, based on the information below. The second is to determine the best blade characteristics, based on the information pro- vided on the following pages. Your choice should be based on:
• the material to be cut. • geometry of the cut.
• the capabilities of your band machine. High Speed Steel Bi-Metal Band Saw Blades
For cutting tough and abrasive materials. These blades are designed primarily for use on cut-off machines with coolant systems, and with power feed. However, they may also be used effectively on contour machines with or with- out coolant systems, especially on difficult to machine steels. DoALL band saw blades with M-42 hss edge, elec- tron-beam welded to high flex back, for these applications are listed below. Blade PenetratorTM Imperial Bi-Metal™ 101 Page 14 11 For cutting materials of varying cross sections, including structurals, tubing, pipe or extrusions, the Decimal Pitch Super Silencer™ is recommended for both cut-off and contour machines. The Decimal-Pitch Super Silencer with hss Matrix edge (based on M-42 cobalt hss) and high flex back reduces high-pitched squeal and blade damaging vibration. This is an excellent blade for efficient sawing of solids, tubing and structural shapes. Blade Page Decimal Pitch Super Silencer™ 13 For general purpose use on cut-off and contour machines, we recommend the versatile Imperial Bi-Metal™ 100, with its M-2 hss cutting edge, electron beam welded to a high- flex back. Blade Imperial Bi-Metal™ 100 Page 10 For the lowest cost-per-cut in sawing mild to tough materi- als in solids, use the Imperial Bi-MetalTM contour or cut-off machines. Blade features a 5-degree positive rake, hss cutting matrix edge, electron-beam welded to an ultra-high strength, high-flex back. Blade Page Imperial Bi-MetalTM102 12 Carbon Steel Band Saw Blades DoALL offers a selection of carbon steel band saw blades for contour sawing and cut-off machines. Applications are listed below: For use on light-duty cut-off and contour saws, use Dart® blade with an all-purpose hard edge and hard back. Suit- able for use with or without coolant systems. Blade Page Dart® 15 For light toolroom, maintenance shop and production ap- plications, and where material and inexperienced opera- tors are a problem, use the DoALL Metal Master blade. For 4
Close-up photo shows how DoALL uses space-age electron-beam welding technology to bond super hard (to M-42) hss cutting edges to high-flex steel back. This provides the optimum combination of long tooth wear with maximum band life. DoALL has also pioneered tooth form designs which minimize blade damaging harmonic vibrations.
