Starrett 17039 Welded Bandsaw Blade 4 Tpi Bi-metal M42

Product Description

The STARRETT 17039 is a bi-metal welded bandsaw blade built for demanding cutting applications in metal fabrication and trade shop environments. Manufactured under the Intenss PRO-DIE series, the blade features an M42 high speed steel tooth material bonded to a flexible back, combining tooth hardness with back toughness. At 93.5 inches long and 0.5 inches wide, it runs a constant 4 TPI hook-form tooth pattern with a raker set and positive rake angle. Licensed HVAC shops, pipefitters, fabricators, and general metalworking trades typically install this blade on horizontal or vertical bandsaw machines sized to accept a 93.5-inch loop.

This blade is suited for cutting steel, stainless steel, exotic steel alloys, and non-ferrous metals. The constant 4 TPI pitch provides aggressive material removal in solid stock and structural shapes. The hook tooth form accelerates chip clearance, and the raker tooth set distributes cutting load evenly across the blade width. It is a practical choice for job-shop environments where a single blade must handle a variety of metal types without frequent changeovers.

Key Features

• Bi-metal construction with M42 high speed steel teeth for extended blade life on hard metals
• Constant 4 TPI hook tooth form for aggressive, fast cuts in solid and structural stock
• Raker tooth set for balanced cutting load and consistent chip removal
• Positive rake angle improves feed rate and reduces cutting force
• Flexible back material reduces fatigue cracking during continuous bandsaw operation
• Contour cutting capable for curved or irregular workpiece profiles

Compatibility

Designed for bandsaw machines that accept a 93.5-inch welded loop blade with a 0.5-inch width and 0.025-inch blade thickness. Verify wheel diameter, blade guide clearance, and tension specifications on the host machine before installation.

Installation Notes

Bandsaw blade replacement should be performed by a qualified technician familiar with the host machine. Disconnect power and release blade tension completely before removing the old blade or mounting the new one. Wear cut-resistant gloves when handling coiled or loop blades. Confirm blade tracking and tension per the machine manufacturer guidelines before resuming cuts.
