Milwaukee Large Thread Arbor 3/8″ Shank

MAXIMUM CORE STRENGTH TORQUE TRANSFER

When you’re cycling through heavy-duty boring applications, the interface between your drill and the hole saw is the primary failure point. The Milwaukee 49-56-7040 Arbor is engineered from high-grade hardened steel to eliminate the stripping and shearing common in standard-duty accessories. This 3/8″ large thread arbor is purpose-built to handle the massive torque loads generated by saws 1-1/4″ and larger, ensuring that your power is delivered directly to the cutting edge without vibration or axial runout.

• / HARDENED STEEL CONSTRUCTION: Provides exceptional durability and long-term resistance to deformation under high-stress drilling conditions.
• / LARGE THREAD COMPATIBILITY: Specifically engineered to fit all hole saws 1-1/4 in. and larger for a secure, non-slip fitment.
• / 3/8″ UNIVERSAL SHANK: Optimized geometry fits all standard 3/8 in. and larger drill chucks for maximum jobsite versatility.
• / PRECISION MACHINED THREADS: Ensures a dead-nuts center alignment to reduce wobbling and extend the life of your hole saw teeth.
