Starrett 10489 Welded Bandsaw Blade 4 Tpi Carbon Steel

Product Description

The STARRETT 10489 is a welded carbon steel bandsaw blade from the Duratec SFB series, designed for continuous cutting operations on stationary band saws. It measures 93.5 inches in total loop length and 0.5 inches wide, with a blade thickness of 0.025 inches. The blade runs a constant 4 teeth per inch (TPI) skip tooth pattern with a raker set and straight rake angle, making it well suited for fast, aggressive cuts through a range of materials. The flexible back construction helps the blade track cleanly and resist fatigue during extended cuts. Installation requires no additional welding — the blade arrives ready to mount.

This blade is configured for contour cutting applications and handles ferrous metal, non-ferrous metal, plastic, and plywood. It fits band saws that accept a 93.5-inch loop blade in the 0.5-inch width class. The skip tooth geometry clears chips efficiently, which reduces heat buildup in softer materials like plastic and non-ferrous stock. It is a practical general-purpose blade for metal fabrication shops, millwork operations, and maintenance trades that run variable stock types through a single machine.

Key Features

• Constant 4 TPI skip tooth pattern for aggressive material removal and efficient chip clearance
• Raker tooth set delivers consistent, straight cuts in ferrous and non-ferrous metals
• Carbon steel blade and tooth construction throughout the Duratec SFB series
• Flexible back resists cracking and fatigue during extended bandsaw operation
• Pre-welded loop — mounts directly without field welding
• Rated for contour cutting across ferrous metal, non-ferrous metal, plastic, and plywood

Compatibility

Designed as a direct-mount replacement blade for stationary band saws accepting a 93.5-inch loop blade, 0.5 inches wide, with a 0.025-inch kerf thickness.

Installation Notes

Band saw blades should be installed by a qualified technician familiar with the specific machine make and model. Disconnect and lock out power to the saw before opening blade guards or handling the blade. Verify blade tension and tracking per the machine manufacturer specifications before making cuts. Wear cut-resistant gloves when handling the coiled or looped blade, as the tooth edge presents a laceration hazard.
