238M - 2-3/8" Bi-Metal Hole Saw, Heavy Duty Pipe & Metal Cutter

Precision 2-3/8" Bi-Metal Hole Saw for Industrial Applications

The Techniweld 2-3/8" (60mm) Bi-Metal Hole Saw is engineered for professional machinists, fabricators, and MRO specialists requiring reliable cutting performance in diverse materials. Constructed with a hardened high-speed steel (HSS) cutting edge electron-beam welded to a tough, shock-resistant alloy steel back, this tool offers the optimal balance of durability and flexibility. The shatter-resistant design ensures safety during heavy-duty operation, while the bi-metal composition resists heat buildup, significantly extending tool life compared to standard carbon steel saws.

This specific diameter, 2-3/8 inches, corresponds to the outside diameter of standard 2-inch pipe, making it a critical size for plumbing, HVAC, and structural pipe applications. It features a variable pitch tooth geometry, typically 4/6 TPI, which serves dual purposes: it reduces harmonic vibration to ensure a smooth cut and facilitates rapid chip clearance to prevent clogging and overheating. The saw provides a standard cutting depth of 1-1/2 inches, allowing for single-pass penetration of 2x lumber, heavy-wall pipe, and thick plate steel.

Designed for use with standard arbors having a 5/8-18 thread, this hole saw integrates seamlessly into existing tool cribs. The heavy-duty backing plate eliminates the need for drive plates and prevents hole elongation. Side knockout slots are strategically placed to allow for the easy leverage and removal of stubborn cores, minimizing downtime between cuts. Whether cutting stainless steel, cast iron, aluminum, or nail-embedded wood, the Techniweld 2-3/8" hole saw delivers consistent, burr-free results.
