Starrett OY-9PPL-LLUA BM18 Bi-Metal Unique Porta-Band Blade, 44-7/8-Inch by 1/2-Inch by 0.020-Inch, 3 Pack

  Product description From the Manufacturer Starrett Portable Band Saw Blades are manufactured using bi-metal unique, a new Starrett exclusive material bonding technology. The proprietary solid-state diffusion process guarantees 170 Percent more weld contact area compared to existing bi-metal high-speed steels. The result is significantly reduced fracture and breakage at the HSS/backing material interface. Soon after initial use, the teeth develop a groove in the very thin center of backing material at the cutting edge. This alters the blade area engaged in the cut to create Multi-Edge performance. As a result, the cutting stroke produces dual chips that are more easily removed from the cut. For applications utilizing coolant, more of it flows to the cutting surface. This is the Split-Chip advantage. Compared to other premium blades, Bi-Metal Unique provides faster cuts, longer blade life, and lower cost -per-cut.     Product information Technical Details Part Number CBM18 Item Weight 7 ounces Product Dimensions 18.9 x 6.5 x 0.8 inches Item model number BM18 Material High Speed Steel Item Package Quantity 1 Batteries Included?
