HSS M42 With 8% Cobalt Bi-Metal Hole Saw

【Size】Cutting diameter: 14-210mm, BI hole saws over 51mm require a stronger handle to ensure greater safety; Hole saw depth: 38mm | 1-1/2 inches. Made of raw materials from Japanese brand saw blades.

【Extra-long life】The saw teeth are made of M42 high-speed steel with a hardness of ≥65HRC, which has a longer service life and is rust-resistant and corrosion-resistant. The center drill bit is gold and titanium plated, making it stronger than silver or black.

【High Standard】The hole saws can reach a height of 1.5 inches, with a tooth height of 1.5mm-1.8mm, and can easily cut a variety of thick wood, plywood, plastic, drywall, soft plaster, sandbag board, and thin metal. In addition to stamping cans or recessed lights, they are also suitable for home DIY air ducts, speakers, ceiling lights, etc.

【Professional Use】The hole saw has a variable tooth pitch. The main advantage of this pitch is to reduce vibration and noise during cutting, resulting in smoother cutting. Sawtooth thickness 1.0 mm, height 1.8~2.0 mm.

【Efficient and smooth cutting】Due to the high performance of M42, cutting is convenient and the cut is flat and smooth. The spring on the drill bit will automatically push the disc out of the saw as soon as the hole is completed.
