The WILLIAMS COMFORT PRODUCTS 3906-250-24-100 is a bimetal hacksaw blade designed for cutting metal, conduit, pipe, and other hard materials encountered in trade work. At 10 inches in length with 24 teeth per inch (TPI), this blade delivers fine, controlled cuts suited to thin-walled tubing, electrical conduit, and light structural stock. The bimetal construction bonds a high-speed steel tooth edge to a flexible alloy steel body, producing a blade that resists breakage under lateral stress. Sold in a 100-pack, this product is well suited for shops and service fleets that go through blades at volume.
This blade fits standard 10-inch hacksaw frames used by plumbers, HVAC technicians, electricians, and general mechanical contractors. The 24 TPI configuration is appropriate for medium to thin wall thickness materials, including copper tubing, EMT conduit, iron pipe, and angle iron. It is a practical stock item for service vans, job boxes, and shop inventories where blade replacement is routine.
Designed as an OEM-style replacement blade for standard 10-inch hacksaw frames used across plumbing, HVAC, electrical, and general mechanical trades.
Hacksaw blades are installed by licensed tradespeople and journeymen working in accordance with applicable shop safety practices. Mount the blade with the teeth facing forward, away from the handle, and tension the frame until the blade is rigid with no lateral flex. Wear appropriate eye protection when cutting, and allow the blade to cool before handling after extended use. Replace blades showing visible tooth wear or cracking rather than continuing to force cuts.
